Milk adulteration represents a critical risk for players in the food industry wishing to secure their production facilities against fraud. Dilution, addition of prohibited substances or fraudulent substitutions: these practices, which are often invisible to the naked eye, compromise product quality, expose manufacturers to regulatory risks and jeopardize consumer confidence.

Reliable, rapid milk adulteration testing methods adapted to industrial constraints are now essential for all industry professionals. But what techniques are available today? Should we prefer destructive methods (HPLC, colorimetric tests, etc.) or non-invasive technologies (IRMSNIR, etc.)? And how can we be sure of their effectiveness in real-life conditions?

In this article, we explore the most common forms of adulteration, the limitations of conventional methods, non-destructive innovations, and the strategic role of specialized laboratories like CIRAM in securing the agri-food production system. 

Understanding forms of adulteration and classic detection methods

Compliance with standards and transparency are essential elements of an industrial production strategy in the food industry. That's why it's essential to be aware of the various types of milk fraud and the limits of conventional detection methods, in order to set up a rigorous quality control plan.

Types of milk adulteration in the industry

Milk adulteration methods can take a variety of forms, all of which respond to a short-term economic rationale, but have major consequences for product quality, health safety and regulatory compliance.

The most common practices include :

• Dilute milk with water to increase volumes,
• The addition of cow's milk to differentiated milks (goat's, sheep's),
• The use of vegetable proteins, which are sometimes difficult to detect,
• The addition of chemical neutralizers to mask abnormal acidity,
• The addition of melamine to simulate a compliant nitrogen content.

These spoilages represent critical risks for food industry professionals : between loss of traceability, non-compliance with food safety standards, downgrading of products and increased regulatory risks, the stakes are high.

This type of fraud is not confined to dairy products: the same problems can be found in other sectors, such as honey adulteration or adulterated adulterated essential oils.

It is therefore essential to set up rapid and reliable detection processes, which represent both a lever for industrial performance and tools for legal protection in the face of regulatory quality controls. regulatory quality controls.

Traditional test methods: between usefulness and limitations

Historically, fraudulent milk analysis has relied on destructive or semi-quantitative methods requiring sample degradation. These include :

• High-performance liquid chromatography (HPLC) to detect certain additives,
• Colorimetric tests, simple but not very sensitive analyses,
• Enzyme-linked immunosorbent assays, which are more specific but slow.

Many of these analyses are based on standardized protocols, such as the ISO 8968-1 (determination of nitrogen/protein content in milk) or standard EN ISO 14501 (determination of melamine by liquid chromatography).

These methods for analyzing fraudulent milk are effective under laboratory conditions, but have a number of limitations: they take a long time to implement, are sometimes costly, and are ill-suited to a just-in-time production environment (real-life conditions).

For manufacturers seeking to integrate the detection of milk adulteration into their quality processes, the question arises: how can they guarantee analytical precision, operational speed and preservation of the milk sample? It is in this context, and in response to industrial requirements, that non-destructive techniques come into their own.

The rise of non-destructive techniques for the analysis of fraudulent milk

Constrained by the operational limits of conventional approaches, manufacturers have adopted non-destructive technologies, better suited to production environments, and to the reactivity and traceability requirements of dairy products.

Focus on non-destructive milk analysis techniques

Non-destructive analysis techniques are a concrete response to the challenges of modern quality control in the dairy industry. They enable the detection of milk adulteration without altering the sample, while guaranteeing reduced analysis time, controlled operating costs and easy integration into production lines.

The methods most commonly used by manufacturers include :

• Near infrared spectroscopy (NIR): this is highly prized for its rapid, non-invasive nature, and enables analysis either on-line or in the laboratory. It is particularly well-suited to detecting fraudulent mixtures (e.g. milk cut with water, cow's milk in goat's milk, etc.), while offering a high level of sensitivity.
  
• The mass spectrometry Mass spectrometry may or may not be coupled with chromatography. This method enables fine detection of exogenous proteins or contaminants such as melamine, with high analytical precision. It is widely used in regulatory and legal contexts. This technique is often implemented in accordance with validated protocols, such as the ISO standard 18330which describes the use of mass spectrometry for residue analysis in dairy products.
  
• Immunochromatographic methods: are based on antigen-antibody reactions and offer rapid tests for certain targeted markers (proteins, casein, allergens). They offer the advantage of great portability, particularly in production environments. Methods such as those described in ISO 21528-2 standard or the AOAC guidelines are used to guarantee the reproducibility of antigen detection tests in milk.
  

These tools are a direct response to industrial requirements: the ability to increase analysis rates without sacrificing reliability, while complying with food safety requirements.

Advantages and applications of non-destructive testing for milk adulteration

Non-destructive milk analysis techniques can be seamlessly integrated into quality processes, both upstream and downstream. They provide agri-food professionals with greater responsiveness in the event of an alert or suspicion of non-conformity linked to milk adulteration. They also facilitate product documentation for internal and external audits.

Another interesting quality of these methods lies in their ability to operate without complex preparation, which reduces dependence on specialized technicians and limits handling errors. For production, quality control or regulatory affairs managers, they provide a concrete answer to the question of how to reconcile operational efficiency, compliance and risk anticipation.

The role of specialized laboratories like CIRAM in the fight against milk adulteration

Manufacturers are increasingly relying on partner laboratories capable of combining scientific expertise, regulatory compliance and analytical performance to guarantee reliable, auditable and usable results for their business teams.

Why use an expert laboratory to detect milk adulteration?

Testing milk for adulteration can be a complex business for quality managers. For professionals in charge of manufacturing processes, it requires a thorough understanding of methods, particularly non-destructive techniques, equipment and current standards, which is not their core competence. More and more of them are entrusting these analyses to a expert industrial production laboratory to secure their monitoring, production and quality control processes.

Milk adulteration represents a major risk to the quality, regulatory compliance and food safety of dairy products in the agro-industry. While traditional methods have long served as the analytical foundation, non-destructive techniques such as NIR spectroscopy, mass spectrometry and immunochromatography now offer faster, more sensitive answers that can be integrated into industrial production processes.

Guarantee the naturalness is no longer just a marketing ploy. Manufacturers must meet both regulatory requirements and the need for transparency demanded by consumers. Certifying thenatural origin of a flavor is becoming strategic for players in the food, functional flavor and nutritional supplement industries. However, traditional analytical methods are showing their limitations when faced with the risks offlavor adulterationwhich complicates the distinction between a natural flavor and an artificial flavor.

L'carbon-14 analysisanalysis, an essential component of the science of dating, now offers a reliable, scientifically valid way of demonstrating theauthenticity of flavors at every stage of the industrial cycle, from component sourcing to the finished product.

In this article, we explore why and how this technology can be integrated into the certification process. certificationcertification traceability and quality controlwith a focus on concrete applicationsand the key role played by specialized laboratories in the food industry such as CIRAM.

Flavor naturalness: issues, definitions and limits of conventional methods

Guaranteeing the naturalness of a flavor is a strategic imperative for any manufacturer committed to quality, transparency and compliance.

Understanding the naturalness of flavors in the food and cosmetics industry

A natural flavor is a flavoring substance derived exclusively from plant, animal or microbiological sources, by physical or enzymatic processes, in accordance with EC regulation n°1334/2008. To claim an "X" natural flavor, at least 95% of the flavor components must come from the source mentioned.

For manufacturers, guaranteeing this naturalness implies perfect traceability, controlled sourcing and usable scientific proof. It is also a prerequisite for obtaining natural flavor labeling, for access to certain certifications (BIO, clean label), or for meeting the expectations of R&D, marketing or regulatory departments.

Flavor adulteration: a growing risk for manufacturers

Flavor adulteration occurs when petrochemical components are intentionally or unintentionally introduced into a formulation presented as natural. This practice poses major risks for product marketing: regulatory non-compliance, loss of certification, food fraud, damage to reputation.

However, conventional chemical flavor analysis methods (GC-MS, HPLC, sensory control) are unable to distinguish a compound's fossil or biobased origin, particularly in complex matrices.

That's why it's so important to call on an analytical laboratory specialized in the industry (like CIRAM) and use scientific methods to prove the naturalness of flavors. These techniques, such as isotope analysis and carbon-14 analysis, are capable of accurately detecting any food flavor adulteration, enabling manufacturers to preserve the integrity of their products.

Carbon 14 for authenticity and traceability of aromas

Carbon analysis 14 analysis analysis is an essential technique for validating the authenticity of a product, proving its biosource, and validating control processes when conventional tools reach their limits.

How does carbon-14 analysis work to verify the naturalness of an aroma?

Carbon-14 is a radioactive isotope naturally present in all living matter. However, fossil matter (such as petroleum) no longer contains it, as this isotope decays over time (with a half-life ≈ 5730 years). Thus, quantifying carbon-14 makes it possible to measure the proportion of "modern" (biobased) carbon versus "old" (petrochemical) carbon.

Carbon-14 isotope analysis can be used to detect adulteration, authenticate natural flavors, and even validate the biobased origin of packaging or additives, thanks to gas pedal mass spectrometry (AMS),

The method is fast (results in 5 à 10 days), highly accurate (0.4% absolute absolute uncertainty) and applicable to all types of matrix (liquids, solids, gels, without prior knowledge of composition). Water content does not interfere with the measurement.

CIRAM complies with international standards ASTM D6866 and EN 16640which govern the analysis of the biobased content of materials.

Practical applications of carbon-14 naturalness verification

Radiocarbon analysis of flavors is applicable at all stages of the product life cycle:

• Sourcing and supplier selection
• Product development and formulations
• Quality control for flavor production
• Regulatory compliance assessment
• Natural labeling or organic certification
• Verification of biobased packaging

Carbon-14 analysis is also a relevant technique used in commercial disputes, audits, or to reinforce an industrial group's CSR approach.

In addition to this technique, CIRAM offers stable isotope analysis (δ¹³C, δ¹⁵N, δ¹⁸O, δ²D) via EA-IRMS. This can be used to determine botanical origin, geographical provenance, or to detect finer fraud on complex aromas. This complementary technique enhances the reliability of analyses and secures teams on the market.

Guaranteeing analysis reliability: the key role of specialized laboratories like CIRAM

The effectiveness of verification of a flavour's naturalness by carbon 14 depends as much on the rigour of the method as on the quality of its execution. That's why more and more manufacturers are working with accredited laboratories experienced in natural flavor analysis. 

Why call on an expert laboratory in the biobased industry?

Using an ISO/IEC 17025-accredited laboratory has become a strategic requirement for manufacturers seeking analyses that ensure reliable results, sample traceability, and compliance with regulatory requirements. This accreditation guarantees that analyses, particularly those of stable isotopes, are performed using validated methods by qualified personnel, while being evaluated by the French Accreditation Committee (COFRAC). As a specialist inscientific analysis applied to industry, CIRAM offers manufacturers across various sectors its recognized expertise in graphitization and isotopic characterization through its NF EN ISO/IEC 17025 accreditation (accreditation no. 1-7217, COFRAC Testing, scope available at www.cofrac.fr). 

In this article, we explore why using anISO/IEC 17025 accredited laboratory is essential to guarantee the reliability of stable isotope analyses, to understand the requirements linked to graphitization, and to master the challenges of traceability, compliance and competitiveness in a demanding industrial context.

Understanding ISO/IEC 17025 accreditation: issues and regulatory framework

Manufacturers seeking traceable, verifiable and usable data are well advised to use a laboratory accredited to ISO/IEC 17025 for their stable isotope analyses. The international recognition of results makes this a strategic lever for any company wishing to expand its activities. 

What is ISO/IEC 17025 recognition and why is it crucial to the industry?

ISO/IEC 17025 is the international standard defining the general competence requirements for testing and calibration laboratories. It covers both technical aspects (validated methods, accuracy, measurement uncertainties) and management aspects (traceability, impartiality, integrity of results and competence of personnel in particular). An ISO/IEC 17025-certified laboratory thus proves that it masters the entire chain.

For manufacturers, this means :

• reliable, comparable results between laboratories
  
• complete traceability
  
• quality risk management
  
• easier regulatory compliance
  

In the specific case of stable isotope analysis, choosing CIRAM, a laboratory accredited to NF EN ISO/IEC 17025, (accreditation no. 1-7217, COFRAC Essai, scope available on www.cofrac.fr) guarantees that every stage in the analysis process, from sample reception to results processing, is governed by strict procedures that are regularly audited.

You may be wondering why it's so crucial to choose an accredited laboratory for stable isotope analysis - and what risks are involved?
Today, it's well known that untraceable data or data from uncontrolled procedures can mislead a manufacturer's strategy (material qualification, supplier control, product lifecycle management). This can have serious consequences for your company, both internally and externally. ISO/IEC 17025 recognition provides a reassuring framework for your activities.

The role of the COmité FRançais d'ACcréditation (COFRAC) and international scope (ILAC MRA)

In France, ISO/IEC 17025 accreditation is issued by the COFRAC (Comité Français d'Accréditation). This is an independent body which carries out demanding assessments based on a detailed reference system.

"But how does ISO/IEC 17025 recognition guarantee the quality of isotopic results?" Obtaining this accreditation is a demanding process for any laboratory wishing to be accredited. It requires rigorous method validation, proven staff competence, calibrated instrument maintenance and full traceability of every measurement.

This recognition guarantees that analyses carried out by an ISO 17025 laboratory will be accepted without re-checking, reinforcing the efficiency of the supply chain and compliance processes for manufacturers operating on an international scale. Choosing an ISO 17025-accredited laboratory means integrating analytical quality as a lever for industrial competitiveness. It's an integral part of any winning industrial strategy.

Why is graphitization a guarantee of quality control?

Graphitization is a key stage in the preparation of samples for radiocarbon analysis by mass spectrometry. It consists in extracting the carbon present in a pure graphite sample.

The graphitization process follows strict protocols, validated and documented within the framework of ISO/IEC 17025 accreditation. Each batch of material used, each temperature parameter, each reduction time is controlled to ensure complete traceability and reproducibility of results.

Industrial R&D teams tend to wonder about the technical challenges involved in graphitization under accreditation. These include the chemical stability of graphite, the elimination of contaminants, and the precise control of conversion conditions.

But how does an ISO/IEC 17025-accredited laboratory guarantee material traceability? CIRAM ensures traceability by systematically recording operating conditions, double-checking materials and keeping all raw results, in line with internal requirements and those of ISO/IEC 17025.

For example, ISO/IEC 17025 compliance ensures reliable quality control of raw materials, secure origin labelling and optimized traceability of finished products.

Sectors concerned and concrete impacts (industry, R&D, supply chain)

Accredited stable isotope analyses (scope available on www.cofrac.fr) are therefore finding concrete applications in several industrial sectors:

• Agri-food Food: for verification of origin and fraud prevention
  
• Biobased materials: certifying organic origin
  
• Chemistry and polymers Lifecycle monitoring and comparative batch analysis.
  
• Pharmaceuticals: for analytical traceability in R&D and regulatory controls.
  

Access to reliable isotopic data makes it possible to objectify physico-chemical phenomena, secure innovations and accelerate validation phases. These aspects are crucial for R&D teams seeking to optimize and secure their activities.

But using an ISO/IEC 17025 accredited laboratory is not just for R&D teams. For the supply chain, it secures critical data throughout the chain, reducing disputes and reinforcing the compliance of ISO 17025-accredited laboratories and their partners.

Control, compliance and value enhancement: controlling risks and processes

As a manufacturer, your ability to demonstrate the reliability of your analyses is not an option: it's a requirement for your customers or regulatory bodies. ISO/IEC 17025 accreditation therefore becomes a key asset for securing audits, enhancing compliance and reinforcing your technical credibility.

Ensure the validity and conformity of its analyses

CIRAM is accredited to NF EN ISO/IEC 17025, and is committed to producing technically valid results, accompanied by certificates of analysis with the use of the accreditation mark (accreditation n°1-7217, COFRAC Essai, scope available on www.cofrac.fr) for ISOTOPES analyses and graphitization. This document attests to the rigor of the process, from sample preparation (for graphitization, for example) to the processing of analytical data. It certifies that the analysis has been carried out according to validated methods, by competent personnel, with calibrated equipment and under quality supervision.

The analyses carried out thus offer a number of benefits in terms of validity and conformity. Indeed, the audits carried out as part of ISO/IEC 17025 accreditation and its maintenance verify not only technical compliance, but also the way in which risks and opportunities are identified and dealt with. The laboratory must demonstrate a thorough understanding of its critical processes to ensure consistent reliability.

Enhancing the value of using an accredited laboratory: image, safety and competitiveness

For a manufacturer, integrating an ISO/IEC 17025 accredited laboratory into its production or R&D chain means gaining in :

• Scientific credibility: by demonstrating the rigor of its quality approach
  
• Control customer satisfaction: by having and producing standardized, immediately usable reports
  
• Competitive edge: by offering customers products that are traceable, compliant and technically validated
  

Management teams can therefore choose to communicate their use of an ISO/IEC 17025 laboratory. It's a way of highlighting their mastery of quality control, their high standards, and their desire to provide their partners with usable, comparable results.

By opting for an ISO/IEC 17025 accredited scientific analysis laboratory, manufacturers do more than just outsource an analysis service: they align themselves with international best practice in their sector.

Traceability, sustainability, and transparency have become essential requirements for manufacturers due to changing regulations and consumer pressure. As such, the ISCC Plus certification serves as a key standard for industry professionals committed to utilizing bio-based or recycled raw materials. 

In this article we'd like to share essential information on the specifics of the ISCC Plus standard and the process involved in obtaining it. We will also explore its technical challenges, such as mass balance, and the fundamental role of scientific studies carried out by industrial product analysis laboratories in securing compliance.

Understanding the ISCC PLUS certification framework

The numerous sustainability and traceability requirements make ISCC Plus certification essential for industry professionals. It provides a dedicated framework for bio-based supply chains, while ensuring regulatory and environmental compliance.

Definition and scope of ISCC Plus certification

The ISCC Plus certification or International Sustainability and Carbon Certification, is a voluntary certification system designed to validate the sustainability characteristics of alternative raw materials. The system defined by ISCC Plus is designed for non-energy markets, including the food industry, biosourced packaging , recycled plastics and green chemistry. 

Unlike ISCC EU certification, which targets biofuels under the European RED II directive, the ISCC Plus system meets the need for traceability and certification of biobased sustainability in sectors not covered by energy regulations.

ISCC Plus defines strict principles: 

• Complete traceability of biobased raw materials
• Application of social and environmental criteria (human rights, preservation of soil and biodiversity)
• Verification of compliance via an annual ISCC Plus certification audit. 

Its scope of application covers both bio-sourced products and recycled materials, with a view to the circular economy.

This certification is compatible with other systems, such as ISO 14001, and provides international recognition of manufacturers' environmental commitments.

Why has ISCC PLUS certification become strategic for manufacturers?

Growing consumer and regulator demand for sustainable, traceable, greenwashing-free products is forcing manufacturers to prove the biobased authenticity of their ingredients and packaging. ISCC Plus offers a rigorous, recognized reference framework for structuring this demonstration.

Furthermore, bio-based traceability is supported by tools such as carbon-14 analysis (in accordance with ASTM D6866 or EN 16640) and is essential for avoiding penalties related to potential non-compliance with ISCC Plus. 

Analytical laboratories such as CIRAM are able to comply with the system described by ISCC Plus, and play a decisive role in providing scientific proof, notably through stable isotope analysis, authenticity testing of natural ingredients, or implementing biobased agri-food quality control.

To this end, certification gives manufacturers a sustainable competitive advantage, especially SMEs wishing to access international markets while securing their compliance.

Obtain and maintain ISCC PLUS certification

ISCC Plus compliance cannot be improvised: it requires structured preparation, rigorous document management and an integrated traceability strategy at every link in the production chain.

The certification process: stages, costs, deadlines

The process for obtaining ISCC Plus certification follows a standardized methodology, applicable to all companies wishing to add value to their biobased or recycled flows. It begins with a preliminary internal audit, often carried out in conjunction with ISCC Plus certification support, to identify gaps and update internal procedures. Industry-specialized analysis laboratories such as CIRAM play a key role in initiating this process, thanks to their dual expertise in biobased product analysis and compliance consulting. 

The documentary resources to be prepared cover the origin of bio-based raw materials, production data, supplier contracts, mass balance system management, quality control plans and non-conformity management procedures.

The ISCC Plus certification audit is then carried out by an approved body. In particular, it assesses :

• Verifiability of material flows (upstream/downstream traceability)
  
• Compliance with environmental and social criteria (known as Major Musts)
  
• Compliance with technical standards (e.g. EN 16640)
  

In the event of discrepancies, a period of 40 days is allowed to correct any non-conformities observed. The cost depends on the size of the company, the complexity of the supply chain, and the scope of the audit. On average, the budget is between €4,000 and €10,000 for initial certification. Annual renewal requires an annual ISCC Plus audit.

Critical points: mass balance, traceability, food requirements

What is "mass balance ISCC Plus"? It's a material accounting system used to certify the biobased component of a final product, even if it's not physically separable. Mass balance imposes a strict logic of balance between inputs and outputs, verified at each audit.

It is important to note that additional requirements apply to the agri-food sector, notably for natural ingredients, flavors, bio-based food additives or essential oils. Specific analyses must therefore be carried out to demonstrate ISCC Plus regulatory compliance, via carbon-14 analysis, stable isotope analysis or agri-food biosourced authenticity tests.

Specialized laboratories, such as CIRAM, play an essential role in validating the technical conformity of products before and after audits (particularly for renewals or in the event of deviations), and help to ensure smooth certification management over the long term.

The role of laboratories and prospects for manufacturers

In a context of growing standardization, manufacturers need to rely on reliable technical partners to secure their compliance and anticipate regulatory changes linked to ISCC Plus certification.

Support from specialized laboratories: a lever for compliance

Biobased traceability requirements call for tangible, verifiable proof at every stage of the chain. This is where the involvement of an analytical laboratory such as CIRAM, familiar with ISCC Plus requirements, becomes strategic.

CIRAM performs standardized analyses such as :

• Carbon 14 analysis (ASTM D6866 or EN 16640) validates the renewable origin of raw materials.
  
• Stable isotope analysis is complementary for identifying the botanical and geographical origin of an ingredient.
  
• Conformity testing of bio-based ingredients such as flavors, additives, essential oils or encapsulation supports.
  
• Advice on setting up a biobased agri-food quality control system, including reports to be used during the ISCC Plus certification audit.
  

The scope of our support enables us to achieve a dual objective: to guarantee regulatory compliance, and to avoid any non-compliance during the audit, which could lead to suspension or refusal of certification. A recognized laboratory also makes it possible to list the documents to be provided during an ISCC Plus audit.

Maintain, enhance and anticipate the evolution of ISCC Plus certification

ISCC Plus certification is not set in stone: it evolves in line with ESG policies, European regulations (EUDR, Green Deal), market expectations and consumer demands. Manufacturers must therefore integrate certification into their overall sustainable development strategy.

This includes :

• Integration with other recognized standards such as ISO 14001, BRC, FSSC 22000, to optimize documentation resources.
  
• Upgrading the skills of in-house teams to manage traceability, cross-checks and annual ISCC Plus audits.
  
• Adaptation of the approach for agri-food SMEs, with modular solutions and support from expert partners such as industrial analysis laboratories.
  

Manufacturers can rely on robust scientific analyses carried out by laboratories such as CIRAM, and reliable document management tools to obtain and maintain their certification, as well as to use it as a differentiating commercial and strategic lever.

ISCC Plus certification has become an essential standard for manufacturers committed to a sustainable, traceable approach that complies with regulatory requirements. To succeed in obtaining this essential certification, manufacturers need to understand its specific features, structure their certification process, master mass balance management and rely on reliable scientific analyses.

In this context, laboratories play a decisive role. CIRAM, a recognized expert in radiocarbon (carbon 14) analysis and biosourced authenticity, supports manufacturers in the technical validation of their products, the preparation of audit files and the securing of their conformity.

The standard EN ISO 21644 defines the analytical methods for determining the bio-based fraction of solid recovered fuels (SRF). This study is a key issue for manufacturers engaged in energy transition and regulatory compliance. Through rigorous analyses, this standard ensures the traceability and quality of materials used in industrial processes.

In this article, we explore the specifics of the EN ISO 21644 standard and its implications for industrial applications. You will also learn about the requirements for bringing your processes into compliance with this standard. We will conclude by highlighting the importance of laboratories and their analyses in supporting manufacturers as they adapt their processes to comply with the EN ISO 21644 standard. 

Understanding EN ISO 21644 and its implications for industry

The EN ISO 21644 standard establishes a rigorous methodological framework for the analysis of solid recovered fuels (SRF), in particular by determining their biomass content. This essential standard for manufacturers committed to the energy transition ensures accurate assessment of the environmental impact of SRF, while facilitating their integration into demanding industrial processes.

Definition and objectives of EN ISO 21644

ISO 21644 specifies the methodologies used to assess the proportion of biomass contained in these fuels. It was adopted to harmonize SRF analysis practices and replaces the former EN 15440 standard, improving the accuracy of results and their comparability between laboratories.

Its main objective is to ensure the traceability and conformity of CSR used in energy-intensive industries (including cement kilns and thermal power plants). This standard was born out of a desire to standardize methods to better control the carbon footprint of SRF and optimize their energy recovery.

CSR analysis methods according to ISO 21644

ISO 21644 recommends various analytical and sample preparation techniques for determining the biobased fraction of a RSC:

• Carbon-14 (¹⁴C) analysis : This is the gold standard method because it allows for the quantification of biomass content by distinguishing between fossil carbon and bio-based carbon (here, 14C is proportional to the biomass content of the CSR). This method is suitable for all types of samples and uses a sample size ranging from 0.4 to 2 g for particles with a nominal size of 1 mm or less.
• Selective dissolution (SDM) : is used to isolate certain material fractions and refine the quantification of biobased elements. It is based on the property of biomass to be dissolved in a sulfuric acid/hydrogen peroxide mixture. This method requires at least 5 g of material for a maximum nominal particle size of 1 mm or less.
• The manual sorting method (Msort): although more empirical (based on visual examination of fractions and their separation according to nature and origin), it remains a complementary approach in certain cases. This method requires a sample quantity in compliance with ISO 21645 (upon receipt), as calculated in EN 15443.

The use of these methods guarantees a precise assessment of the sustainability of SRFs and their compliance with environmental regulations. They are essential for manufacturers wishing to reduce their dependence on fossil fuels and improve their carbon footprint.

Where to get analyze my CSR ?

Specialized laboratories, such as CIRAM, offer analyses that comply with current standards. Using advanced techniques such as mass spectrometry and radiocarbon analysis, they ensure reliable measurement of the biomass content in RDF and other industrial materials. This expertise enables manufacturers to optimize their processes and ensure compliance with regulatory requirements.

CSR requirements and compliance with EN ISO 21644

The ISO 21644 standard imposes strict criteria for sample preparation, analysis methodology and interpretation of results, in order to guarantee the reliability of analytical results and ensure compliance with regulatory requirements. Manufacturers must rely on these standardized procedures to avoid discrepancies and guarantee measurement repeatability.

Criteria for CSR

Sample preparation is a key step in obtaining usable results. ISO 21645 provides a framework for sampling and storage protocols, to guarantee the representativeness of the RSC analyzed. In addition,ISO 21646 specifies chemical and physical sample characterization methods.

The minimum quantities required vary according to the technique used:

• For carbon-14 analysis, a sample of just a few grams is generally sufficient.
• Physico-chemical methods require larger volumes, up to several hundred grams.

The expression of the results is standardized: the biosourced fraction of a RSC can be indicated in terms of carbon content, mass or energy content. 

Sector challenges and applications for manufacturers

Compliance with CSR standards represents a strategic challenge for several sectors:

• Cement industry and thermal power plants: they have to demonstrate the sustainability of their energy sources. Highly energy-intensive, their activities are particularly exposed and controlled. 
• Waste recycling: in particular via pyrolysis and gasification of bio-based materials. This sector is at the heart of environmental issues. 
• Agri-food: this sector uses biobased carbon measurements to assess product authenticity and compliance with environmental labels.

The rigor of ISO 21644, ISO 21645 and ISO 21646, which govern sample preparation, analysis methods and interpretation of results, is an essential pillar in guaranteeing the traceability, comparability and regulatory compliance of CSR. These standards provide manufacturers in the energy, recycling and agri-food sectors with a reliable framework for enhancing their environmental and operational performance. 

To achieve this, manufacturers can rely on specialized industrial analysis laboratories that use these methods and support their teams in integrating them into their business processes.

The key role of analysis laboratories like CIRAM for manufacturers

Beyond their composition, biobased paints need to prove their performance and positive impact on the environment to establish themselves as credible alternatives to synthetic paints for manufacturers.

Performance and durability testing of bio-based industrial paints

Biobased paints can't just be environmentally friendly: they also have to meet the high standards of industrial applications. These include rigorous tests to assess their mechanical resistance, durability under extreme conditions (heat, humidity, friction) and adhesion to various substrates.

Today's tests no longer focus solely on mechanical or chemical resistance, but also include criteria relating to the interaction of paints with the materials to which they are applied. For example, bio-based formulations can improve adhesion on complex surfaces such as composites or light alloys, commonly used in the aerospace and automotive industries.

At the same time, performance tests now include analyses of industrial paints for long-term stability under extreme conditions, as well as for compatibility with biobased multilayer systems.

These new approaches ensure that paints incorporating biobased products do not compromise durability or the requirements of the most demanding industrial sectors. By collaborating with specialized biobased paint analysis laboratories like CIRAM, manufacturers can ensure that the composition of their products meets these new standards, while offering innovative, sustainable solutions.

Environmental impact of industrial paints and bio-based coatings

The environmental impact of biobased paints can be seen primarily in their reduced carbon footprint and overall life cycle. By integrating renewable raw materials and minimizing VOC (volatile organic compound) emissions, paints incorporating biobased products contribute to reducing negative impacts on air quality and climate.

According to the “Bio-based Product” label, some products contain up to 60% biomass sourced in France, reinforcing their local footprint and their contribution to the circular economy. For manufacturers, this is a strong selling point in a sustainable development strategy, limiting volatile organic compounds for regulated markets such as aviation, construction or the automotive industry. 

The Life Cycle Assessment (LCA) of bio-based paints enables us to evaluate their overall impact, from the production of raw materials to their end-of-life. This approach guarantees that paints meet environmental criteria at every stage of their use. Increasing the proportion of paints produced using biobased products not only enables manufacturers to reduce their carbon footprint, but also to meet their internal and external CSR objectives.

Biobased paints represent a major advance for industry professionals looking for new processes. Their integration relies on a thorough understanding of standards, precise analysis of composition, and rigorous testing to guarantee their durability and low environmental impact.

Adulteration of essential oils is a major challenge for professionals in theindustry as it jeopardizes the quality of their products and their regulatory compliance.

In this article, we'll explore detection techniques, authentication methods and the importance of laboratory analysis in guaranteeing the purity and traceability of essential oils. You'll also find out why analyses such as carbon-14 and isotope ratios can help ensure the safety of your formulations. 

Understanding the adulteration of essential oils

The adulteration of essential oils is a major problem for the food the food industry to guarantee to guarantee the purity of their products. It is essential to understand its mechanisms in order to better detect and avoid the risks associated with the use of adulterated products.

Definition and challenges of essential oil adulteration

Adulteration of essential oils occurs when an oil is diluted or modified by the addition of undeclared foreign substances. These modifications can include the addition of solvents or less expensive oils to reduce production costs, without this being mentioned on the label. For manufacturers, the impact of such adulteration is far greater than a simple drop in quality: it can lead to health risks for end-users, as well as defects in cosmetic or pharmaceutical product formulations. 

Industry professionals need to understand that adulteration not only affects the performance of their products, but also their compliance with current regulations. An adulterated essential oil can not only compromise the efficacy of formulations, but also lead to health risks. For example, the use of adulterated essential oils in wellness or cosmetic products can cause skin irritation or other undesirable effects. Health authorities could penalize the company if these effects affect all users.

This underlines the importance of adulteration testing to guarantee the quality and safety of finished products .

Adulteration problems are not confined to the cosmetics sector: they also affect other natural ingredients, such as adulterated honey. From milk adulteration tests have also revealed the extent of these fraudulent practices.

Geographical origin and traceability of natural ingredients

The geographical origin of natural ingredients such as essential oils is a key indicator of their quality and authenticity. Certain essential oils, such as lavender from Provence or sandalwood from India, are renowned for their unique properties, derived from their terroir. For industry professionals, it is therefore essential to ensure complete traceability of raw materials, since this makes it possible to verify not only their origin, but also the conditions under which they were produced. Reliable traceability helps to ensure that oils have not been altered throughout the supply chain.

The traceability of natural raw materials is a fundamental pillar for manufacturers seeking to certify the authenticity of their bio-based products. Strict control of suppliers and systematization of regular tests, such as isotopic analysis or carbon-14 analysis, are effective ways of determining whether the declared origin is respected. These methods also ensure that essential oils meet the required purity standards, thus avoiding any risk of regulatory non-compliance.

Detection and authentication methods

The industrial manufacturing process requires reliable and precise solutions for testing the purity of essential oils. Several methods are available to ensure product authenticity and meet quality requirements.

Tests to detect adulteration of essential oils

Detecting the adulteration of essential oils relies on specific, rigorous tests. Among the most commonly used techniques is gas chromatography (GC), often coupled with mass spectrometry. These methods can be used to separate the various components of an essential oil and compare their profile with a reference to identify foreign or undesirable substances. For industry professionals, these analyses are crucial as they provide precise results on the composition of the essential oil, guaranteeing that it has not been altered by chemicals or solvents.

In addition, advanced methods such as isotope analysis or carbon-14 analysis enable us to verify the bio-sourced origin of essential oils, confirming that they come from authentic natural raw materials and not synthetic sources. These analyses are essential to guarantee product purity and compliance with current regulations. 

Verification of purity and authenticity: advanced analyses to guarantee quality

Carbon-14 analysis is one of the most advanced methods for verifying the authenticity of essential oils.

Products of natural origin contain carbon 14, whereas petrochemical components are totally devoid of it. This method offers industry professionals a reliable guarantee of the purity of essential oils, ensuring compliance with the requirements of natural and biobased labels.

Stable isotope analysis allows us to trace the geographical origin of essential oils. By studying the isotopic ratios of carbon, hydrogen and oxygen, we can determine the environment in which the plant was grown, and thus authenticate its origin. For manufacturers, this analysis offers double assurance: not only does it confirm the purity of the oil, but it also guarantees that the ingredients used do indeed come from the advertised sources, thus contributing to complete traceability and protection against fraud.

Quality control and the importance of laboratory analysis

Ensuring the quality and traceability of the essential oils used in products is essential for manufacturers. Analytical laboratories therefore play a crucial role in this process by guaranteeing the integrity of bio-based products.

Quality control and certification of biobased products: criteria and standards to be met

The quality control of essential oils begins at the raw material selection stage. Industry professionals must ensure that each batch of essential oils meets strict purity criteria and complies with current standards. These criteria include absence of adulterants, compliance with organic certifications, and respect for authorized impurity thresholds. To obtain 100% natural product certification, it is necessary to demonstrate that the oils really do come from genuine sources, and that they have not undergone any unauthorized modification or dilution. 

To guarantee the quality and authenticity of essential oils used in the cosmetics industry, standards and certifications validate the origin and purity of the raw materials used.

• ASTM D6866 Standard: The ASTM D6866 standard is widely used to certify bio-based products. This standard relies on carbon-14 analysis to measure the percentage of naturally derived components. This allows manufacturers to verify and promote the sustainability of their ingredients. Adhering to this standard helps build consumer trust and avoid the risk of non-compliance.
• Certification criteria and eco-responsible labels: labels such as EcoCert or Cosmebio certify that essential oils are chemical-free and natural. The products used must be free from adulterants and comply with authorized impurity thresholds. Manufacturers can rely on these labels to guarantee formulations that comply with international standards.

The role of laboratories in natural product analysis: from traceability to authentication

Laboratories that analyze bio-based products play a crucial role in ensuring the traceability of natural raw materials and the authenticity of essential oils. Adulteration tests on finished products enable laboratories to detect any addition of foreign or synthetic substances, thereby ensuring that essential oils meet the required standards. 

By calling on specialized analysis laboratories such as CIRAM, manufacturers can benefit from : 

• Ingredient authentication tests: techniques such as carbon-14 analysis and isotope analysis are used to verify the purity of essential oils. These analyses are used to define the composition of a cosmetic product (natural vs. synthetic percentage), but also to authenticate products from organic farming or to identify plant origins. The results of these tests enable manufacturers to guarantee the authenticity of their raw materials.
• Traceability and regulatory compliance: the laboratories verify the regulatory and normative compliance of raw materials. Thanks to isotope analysis, they can track the geographical origin and production conditions of products, and guarantee that they are of high quality and comply with regulatory requirements.
• Support for the integration of analyses and regulatory compliance into industrial processes: our laboratories work closely with manufacturers to integrate quality and compliance analyses throughout their processes.

Methanization offers manufacturers a solution for optimizing their energy and recovering their waste. But while setting up such a project requires solid financial backing and rigorous technical support, what financing options are available to manufacturers?

In this article, we explore the methanization subsidies available, and the vital role of analytical laboratories in bringing these initiatives to fruition. 

Biogas production and its importance for industry

Biogas production through methanization represents a strategic opportunity to diversify energy sources and reduce the carbon footprint of industrial activities. However, it requires appropriate support to maximize benefits and ensure integration into production processes.

Biogas production and methanization: what are they?

Methanization is a biological process that transforms organic matter into biogas, composed mainly of methane and carbon dioxide. The latter can be used as a renewable energy source to produce electricity, heat or fuel. For manufacturers, biogas represents a solution for the future, enabling them to valorize the organic waste from their production while meeting energy transition targets.

Biogas production requires facilities that vary in size and capacity. Processing facilities must be carefully optimized to ensure efficient, cost-effective biogas production. To achieve this, it is crucial to control every stage of the production project, from the choice of raw materials to the management of by-products.

Biogas: what are the strategic advantages for manufacturers?

Biogas production offers several significant benefits for manufacturers. It helps reduce energy costs by enabling the on-site generation of renewable energy, thereby reducing dependence on fossil fuels. Manufacturers can also recover value from their organic waste (food waste, sewage sludge, etc.), which would otherwise be costly to dispose of.

However, biogas production can be a heavy investment. That's why biogas subsidies and other support schemes have been set up to help manufacturers overcome the financial challenges of initial investment in biogas plants.

Financial schemes to support biogas production

Industry professionals wishing to embark on biogas production projects need to be aware of the many support schemes available to cushion investment costs. Subsidies and other financial assistance are available to help secure the project's financial package and increase its chances of success.

Methanization subsidies available to manufacturers

Subsidies generally account for 10% of the funding for an industrial biogas project. Among existing subsidies, the methanization subsidy is one of the main ways of supporting biogas production. Offered by various bodies, includingADEME and local authorities, it covers part of the investment involved in setting up methanization units. Since the launch of methanization in France, ADEME has provided financial support for over 150 projects. In 2020, ADEME introduced a lump-sum approach to standardize access to its support. In 2023, flat-rate support for biomethane injection projects will be €45/MWh, with a ceiling of €700,000 per project. 

Specific criteria such as a prior feasibility study, minimum energy efficiency and Qualimétha certification are required to qualify for these grants. To obtain these subsidies, manufacturers must put together detailed technical files demonstrating the project's economic and environmental viability. 

Finally, some regions also offer specific subsidies for projects located in rural or industrial areas. These subsidies can often be combined with national subsidies, significantly reducing the cost of setting up a biogas plant.

Optimizing financing and preparing applications

A number of financing options are available to support a methanization project. These are generally distributed as follows: 80% bank loans, 10% equity capital and 10% subsidies. To maximize access to subsidies, it's crucial to structure the project's financial package properly. A common strategy is to combine several sources of financing: methanization subsidies, regional grants and soft loans. For example, some banks offer specific loans for methanization projects, with preferential interest rates.

In partnership with Bpifrance, ADEME is offering an unsecured loan of up to €1 million for methanization projects meeting strict agri-environmental criteria. This loan enables projects to be co-financed alongside conventional bank financing. A practical guide and financial simulation tools are also available to help project developers build their financing plans.

Preparing a project file is a key step in convincing funding bodies. It must include a detailed study of the return on investment, taking into account initial costs, expected energy production and long-term savings. The ability to demonstrate the profitability of the project, while complying with environmental standards, is crucial to obtaining grants. The support of experts, such as specialized consultants or laboratories, may be essential to ensure that the application complies with technical and regulatory requirements.

The key role of analytical laboratories in the success of biogas projects

Financial schemes, while central, are not enough to guarantee the success of a biogas production project. The quality of raw materials, process optimization and compliance with standards are also decisive factors. This is where analysis laboratories like CIRAM come in, to support manufacturers. 

The importance of analysis for optimizing anaerobic digestion projects

The efficiency of the anaerobic digestion process relies heavily on the quality of the organic materials used and the precise management of process parameters. Analytical laboratories specialized in the biobased industry carry out detailed studies of raw materials, to assess their biogas production potential and detect any contaminants that could affect the performance of anaerobic digestion units.

Several analysis methods can be used in a project. Radiocarbon analysis of biogas enables the proportion of biogenic carbon to fossil carbon to be determined. This distinction is essential for manufacturers wishing to prove the proportion of biomass used in their energy production process, particularly to meet environmental requirements and benefit from methanization subsidies. The measurement is based on carbon-14 concentration, a key indicator for assessing the biobased content of gases emitted or biogas produced, in accordance with standards such asASTM D6866.

These analyses are essential for anaerobic digestion projects. They enable industry professionals to demonstrate the compliance of their facilities with financial aid eligibility criteria, by proving significant biomass use. Analysis of biogas samples also helps optimize production processes by adjusting the feedstock mix. This maximizes energy efficiency while minimizing environmental impact. Biogas and flue gas analysis laboratories can therefore intervene at various stages of a project to assess its profitability and identify possible optimizations. 

Technical support from laboratories for biosourced industry professionals

Analytical laboratories such as CIRAM can assist manufacturers in drawing up the technical documents required to obtain methanization subsidies. Their role is to ensure a smoother transition between project development stages, by verifying that the analytical results comply with the requirements of the funding bodies. 

Technical support includes recommendations on equipment selection and plant configuration. A well-designed anaerobic digestion project is based on an understanding of the interactions between materials, technology and environmental parameters. The analysis laboratory plays a key role in providing manufacturers with precise data and advice based on concrete results. This ensures that anaerobic digestion plants are optimally integrated into production activities. 

The laboratory's support not only secures financing, but also ensures that the anaerobic digestion plants operate at full capacity, with optimum energy yields.

This collaboration between manufacturers and specialized laboratories is therefore a key factor in the success of biogas production projects. It ensures that the former have the data and support they need to overcome technical and financial obstacles, while benefiting from available support mechanisms.

Biogas production therefore represents a strategic opportunity for manufacturers seeking to reduce their energy costs and valorize their waste while meeting the requirements of the energy transition. Thanks to methanization subsidies and other financial schemes, methanization projects can become profitable, provided they are properly structured in terms of financing and implementation.

Analytical laboratories such as CIRAM play an essential role in ensuring success. By offering raw materials analysis services, CIRAM supports you at every critical stage of your anaerobic digestion project.

Recovered solid fuels (RSF) are an innovative solution adopted by manufacturers to reduce their reliance on fossil fuels while recovering value from waste. As a genuine energy alternative that is both economical and environmentally friendly, RSF is attracting an increasing number of companies. 

But how exactly do CSRs work, and what benefits can they bring to your industrial processes? In this article, we take you through their advantages, the technical challenges to be overcome, and the importance of rigorous quality control by analytical laboratories. 

Understanding solid recovered fuels (SRF)

The energy transition is gradually becoming a priority for many industry professionals. In this context, solid recovered fuels (SRF) offer a credible alternative to fossil fuels. Their advantages go far beyond simply reducing carbon footprints, since they are part of a dynamic of waste-to-energy and energy-cost optimization. However, to exploit their full potential, it is essential to understand their nature, how they are produced and the issues involved in using them in industrial processes.

Definition and characteristics of CSR

Solid recovered fuels (SRF) are fuels produced from non-hazardous waste, such as plastics, paper, wood or textiles. This waste, initially destined for landfill or incineration, is then sorted, transformed and homogenized to create combustible materials with a high calorific value.

Unlike traditional fossil fuels, RDF is the result of a circular recovery process. They recover energy while reducing the amount of household or industrial waste processed by waste management systems. This circularity offers manufacturers a dual opportunity: to reduce their carbon footprint while limiting their dependence on fossil fuels, whose reserves are limited.

CSRs can be tailored to the specific needs of each industrial facility, depending on the composition of the available waste and the requirements of the combustion processes used in heating networks. By adjusting moisture content and particle size, it is possible to optimize the energy performance of SRFs in different boilers or industrial furnaces. CSRs are therefore a major strategic asset for industry professionals looking for more flexible and sustainable energy solutions.

CSR manufacturing processes and quality control

CSR production relies on a rigorous waste treatment process to ensure consistent, reliable fuel quality. The CSR manufacturing cycle begins with the collection and selective sorting of non-hazardous household waste. It is then crushed and dried to achieve the homogeneity required for combustion.

This transformation process includes several crucial quality control stages to ensure that SRF meets industrial specifications in terms of calorific value, moisture content and pollutant content (heavy metals, chlorine, etc.). It is essential for manufacturers to ensure that the solid recovered fuel used in their facilities complies with strict standards, to avoid any risk of equipment corrosion or pollutant emissions.

It is in this context that specialized laboratories such as CIRAM play a fundamental role. Thanks to their advanced analytical methods, these laboratories are able to accurately assess the chemical composition of RDF, its energy potential, and potential contaminants. They provide industry professionals with the advice and data needed to adjust their combustion processes and maximize efficiency while minimizing environmental risks.

CSR quality control is therefore not limited to guaranteeing sufficient calorific value, but also to ensuring that these fuels are adapted to the specific requirements of each industrial process. This includes particular attention to the technical and regulatory aspects governing their use.

Technical challenges of SRF for industry

Making efficient use of solid recovered fuels (SRF) involves overcoming major technical challenges associated with the variability of their composition for industry professionals. This heterogeneity can have a direct impact on the performance of their industrial processes, making laboratory testing essential to guarantee consistent, reliable quality.

Variability in RSC composition: a challenge for manufacturers

Solid recovered fuels, which are derived from the recovery of non-hazardous waste (plastics, textiles, paper or wood), are characterized by their highly heterogeneous composition. The proportions of organic and inorganic components, moisture levels and pollutant content can vary considerably depending on the waste source. This variability creates a major challenge for manufacturers seeking to guarantee efficient, stable combustion.

For manufacturers, the impact of this heterogeneity is manifold. Firstly, fluctuations in the calorific value of RDF can make it difficult to adjust combustion equipment, such as boilers or industrial furnaces. Uncontrolled variations can lead to a drop in energy yield, or untimely shutdowns due to overheating or insufficient combustion. Secondly, the unpredictable presence of impurities such as chlorine or heavy metals can cause material damage, particularly by increasing the risk of plant corrosion. If this phenomenon is not anticipated, it generates additional maintenance costs and shortens equipment life.

To achieve this, it is crucial to take these challenges into account upstream of the energy production process. CSR homogenization, although difficult to achieve on a large scale, can help reduce these performance gaps. In addition, it is essential to adapt combustion equipment control systems to respond to variations in composition. Some manufacturers also use filtration or pre-treatment technologies to minimize the impact of pollutants, but these solutions require initial investment and a high level of technical expertise.

Importance of laboratory testing to guarantee CSR quality

Given the variability in the composition of Solid Recovered Fuels (SRF), the role of analytical laboratories is becoming crucial in ensuring optimal exploitation from an industrial perspective. Rigorous tests enable us to assess the precise chemical composition of SRF, its energy capacity, and the presence of substances potentially hazardous to installations or the environment. This information is vital in order to adjust combustion equipment parameters in real time and ensure stable performance.

An essential aspect of RSC analysis concerns their biosourced content, i.e. the proportion of biomass present in the fuel. Biogenic carbon content, which measures the percentage of carbon originating from biological sources, is a key indicator for assessing the environmental impact of RDF. The radiocarbon method enables this percentage to be accurately determined. This analysis is essential for verifying compliance with regulatory and environmental requirements, particularly for manufacturers seeking to reduce their carbon footprint. Biomass content is often a decisive factor in certification processes and in the awarding of carbon credits.

Laboratory tests, carried out by CSR analysis laboratories such as CIRAM, include stable isotope and carbon14 analyses, in accordance with EN ISO 21644 (formerly EN 15440), which specifies methods for determining the composition of CSR. Analysis of the biobased component also plays a role in compliance with European and international regulations on sustainable development. By mastering these aspects, manufacturers can meet the growing requirements for reducing CO2 emissions.

Having an in-depth knowledge of the composition of SRF prior to its use is essential for industry professionals to better anticipate the necessary adjustments to combustion processes. This enables them to avoid possible fluctuations in performance and maximize plant efficiency, while limiting the risk of unplanned shutdowns or property damage.

On the other hand, these analyses guarantee compliance with current standards, particularly in terms of atmospheric emissions and management of combustion residues. For manufacturers, the penalties incurred in the event of non-compliance can be costly, both in financial terms and in terms of image. By integrating regular testing into their production processes, companies not only reduce the risk of incidents, but also increase the energy efficiency of their facilities, thereby optimizing their operating costs.

SRFs therefore represent a major opportunity for manufacturers seeking to improve their manufacturing processes, from reducing environmental impact to optimizing energy costs. But while these fuels promote energy circularity, they also present major technical challenges, with their variable composition and impact on equipment. 

Using analytical laboratories such as CIRAM is therefore not limited to simple quality control through composition analysis (bio-based content), but also extends to regulatory compliance with current standards. By incorporating solid recovered fuels into their energy strategy, manufacturers gain access to the technical and scientific support essential for maximizing the added value of these fuels while minimizing associated risks. This includes rigorous management of biomass content and biogenic carbon, which are essential for aligning industrial processes with environmental and regulatory standards. If you’d like to benefit from the expertise of a laboratory specializing in RDF analysis, request an analysis of your samples from the CIRAM team and receive expert advice and high-quality results.
