The adulteration of milk 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 the quality of products, expose manufacturers to regulatory risks, and jeopardize consumer trust.

The implementation of reliable, rapid, and industrially suitable adulteration testing methods for milk is now essential for any industry professional. But what techniques are available today? Should destructive methods (HPLC, colorimetric tests, etc.) be favored, or non-invasive technologies (IRMS, NIR, etc.)? And how can their effectiveness be ensured under real-world conditions?

In this article, we will explore the most common forms of adulteration, the limitations of classical methods, non-destructive innovations, as well as the strategic role of specialized laboratories like CIRAM in this system for securing the agri-food production apparatus.

Understanding forms of adulteration and classic detection methods

The adherence to standards and transparency are essential elements of an industrial production strategy in the agri-food sector. It is therefore essential to know the different possible frauds related to milk and the limitations of classical detection methods in order to implement a rigorous quality control plan.

Types of milk adulteration in the industry

Milk adulteration methods can take various forms, all driven by short-term economic logic, but with major consequences for product quality, food safety, and regulatory compliance.

The most common practices include :

• The dilution of milk with water to increase volumes,
• The addition of cow's milk to differentiated milks (goat, sheep),
• The use of plant-based 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 alterations represent critical risks for food industry professionals: between loss of traceability, non-compliance with food safety standards, product downgrading, and increased regulatory risks, the stakes are high.

This type of fraud is not unique to dairy products: the same problems are found in other sectors, notably with honey adulteration or adulterated essential oils.

It is therefore essential to implement rapid and reliable detection processes, which represent both a lever for industrial performance and tools for legal protection against regulatory quality controls.

Traditional test methods: between usefulness and limitations

Historically, the analysis of fraudulent milk relies on destructive or semi-quantitative methods requiring sample degradation. These include:

• The high-performance liquid chromatography (HPLC) which allows the detection of certain additives,
• Colorimetric tests, simple but not very sensitive analyses,
• The enzyme immunoassays, which are more specific but slow.

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

These methods for analyzing fraudulent milk are effective in laboratory conditions, but present several limitations: they are time-consuming to implement, sometimes costly, and are poorly suited to a just-in-time production environment (real conditions).

For industrialists looking to integrate milk adulteration detection into a quality process, the question then arises: how to guarantee analytical accuracy, operational speed, and preservation of the milk sample simultaneously? It is in this context, and in response to industrial requirements, that non-destructive techniques make perfect sense.

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 make it possible to detect milk adulteration without altering the sample, while guaranteeing reduced analysis time, controlled operational 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 techniques for milk analysis can be seamlessly integrated into quality processes, both upstream and downstream of the chain. They ensure better responsiveness for agri-food professionals in case of alerts or suspected non-compliance related to milk adulteration. They also facilitate product documentation for internal or 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?

Milk adulteration testing techniques can be complex for company quality managers. For professionals in charge of manufacturing processes, this requires a fine mastery of methods, particularly non-destructive techniques, equipment, but also current standards, which is not their core competency. Increasingly, they are entrusting these analyses to an expert laboratory in industrial production to secure their monitoring, production, and quality control processes.

The adulteration of milk represents a major risk to the quality, regulatory compliance, and food safety of dairy products in the agribusiness sector. While traditional methods have long served as an analytical foundation, non-destructive techniques such as NIR spectroscopydating, mass spectrometry or immunochromatography now offer faster, more responsive, and integrable solutions for 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.

Thecarbon-14 analysis, an essential component of dating sciences, today offers a reliable and legally defensible scientific answer to demonstrate theauthenticity of aromasat all stages 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 like CIRAM supports.

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

Carbon14 analysis is anessential technique for validating product authenticity, 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 in5 to 10business days), very precise (0.4%absolute uncertainty) and applicable to all types of matrices (liquids, solids, gels, without prior knowledge of the composition). Water content does not interfere with the measurement.

CIRAM complies with international standards ASTM D6866 and , ASTM D6866which 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?

French laboratories specializing in scientific analysis for industry support quality, R&D, purchasing, compliance, and regulatory marketing teams on sensitive projects related to the naturalness of flavors.CIRAM, an expert in analysis for the bio-based industryhas teams with know-how based on:

• standardized, enforceable protocols

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 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 supports 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 will explore why using an accredited laboratory ISO/IEC 17025 is essential for ensuring the reliability of stable isotope analyses, understanding the requirements related to graphitization, and mastering the challenges of traceability, compliance, and competitiveness in a demanding industrial framework.

Understanding ISO/IEC 17025 accreditation: issues and regulatory framework

Industrialists seeking traceable, verifiable, and exploitable data have every interest in using a laboratory accredited to ISO/IEC 17025 for their stable isotopic analyses. Due to the international recognition of the results, this lever becomes strategic for any company wishing to expand its activities.

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

The ISO/IEC 17025 standard is the international reference that defines the general requirements for the competence of testing and calibration laboratories. It covers both technical aspects (validated methods, accuracy, measurement uncertainties) and elements of (traceability, impartiality, integrity of results, and staff competence in particular. A laboratory recognized as competent according to the ISO/IEC 17025 standard thus proves that it masters the entire chain.

For manufacturers, this means :

• results reliable and comparable between laboratories
  
• one full traceability
  
• one Quality risk management
  
• one regulatory compliance facilitated
  

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 (French Accreditation Committee). It is an independent body that carries out demanding evaluations, based on detailed requirements.

"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)

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

• Food industry 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 according to NF EN ISO/IEC 17025 and is committed to producing technically valid results, accompanied by certificates of analysis using the accreditation mark (accreditation no. 1-7217, COFRAC Testing, scope available on www.cofrac.fr) for ISOTOPE and graphitization analyses. This document attests to the rigor of the process, from sample preparation (e.g., in the context of graphitization) to the processing of analytical data. It certifies that the analysis was carried out using 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 industrialists due to evolving regulations and consumer pressure. As such, ISCC Plus certification embodies a key benchmark for industry professionals committed to the valorization of 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 intended for non-energy markets, particularly for the agri-food sectors, bio-based packaging, recycled plastics, and green chemistry.

Unlike the ISCC EU certification, which targets biofuels under the European RED II directive, the ISCC Plus system meets the traceability and bio-based sustainability certification needs for 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.

Note that this certification is compatible with other systems, such as ISO 14001, and allows for international recognition of industrialists' 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.

On the other hand, bio-based traceability is supported by tools such as carbon 14 analysis (in accordance with ASTM D6866 or EN 16640 standards) and is essential to avoid penalties related to potential non-compliance with ISCC Plus.

Analytical laboratories such as CIRAM that enable compliance with the system described by ISCC Plus play a decisive role here in providing scientific evidence, particularly through stable isotope analysis, natural ingredient authenticity testing, or for implementing bio-based 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 ISCC Plus certification process follows a standardized methodology, applicable to all companies wishing to value their bio-based or recycled streams. It begins with a preliminary internal audit, often conducted with support for ISCC Plus certification, in order to identify gaps and update internal procedures. Industry specialist analysis laboratories such as CIRAM play a key role in initiating this process due to their dual expertise in bio-based product analysis and compliance consulting.

The documentary resources to prepare 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 "ISCC Plus mass balance"?It is a material accounting system that allows for the certification of a bio-based share in a final product, even if it is not physically separable. Mass balance imposes a strict balance logic between inputs and outputs, verified at each audit.

It is important to note that additional requirements apply to the agri-food sector, particularly for natural ingredients, flavorings, 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 bio-based authenticity tests.

Specialized laboratories, such as CIRAM, thus play an essential role in validating the technical conformity of products before and after audits (particularly for renewals or in case of discrepancies), and ensure smooth long-term certification management.

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 analytical methods for determining the biobased fraction of solid recovered fuels (SRF). This study is a key issue for manufacturers engaged in an energy transition and regulatory compliance process. Through rigorous analysis, this standard guarantees the traceability and quality of materials used in industrial processes.

In this article, we explore the specifics of EN ISO 21644 and its implications for industrial applications. You will also discover the imperatives of bringing your processes into line with this standard. Finally, we'll look at the importance of laboratories and their analyses in helping manufacturers adapt their processes to comply with EN ISO 21644. 

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

The standard ISO 21644 specifies the methodologies for assessing the proportion of biomass contained in these fuels. It was adopted in order to harmonize CSR analysis practices and replaces the old standard EN 15440, 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

The ISO 21644 standard recommends various analytical and sample preparation techniques to determine the bio-based content of a CSR:

• Carbon 14 (14C) analysis : this is the reference method as 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 SRF). This method is suitable for all types of samples and uses a material quantity ranging from 0.4 to 2 g for a nominal size less than or equal to 1 mm.
• 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 their nature and origin), it remains a complementary approach in certain cases. This method requires a sample quantity in accordance with ISO 21645 (upon receipt), according to the calculations of 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 like mass spectrometry and radiocarbon dating, they ensure reliable measurement of the biomass content in SRF and other industrial materials. This expertise allows manufacturers to optimize their processes and guarantee 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 result interpretation to ensure the reliability of analysis results and compliance with regulatory requirements. Manufacturers must rely on these standardized procedures to avoid observed discrepancies and ensure measurement repeatability.

Criteria for CSR

Sample preparation is a key step to ensure actionable results are obtained. ISO 21645 standard governs sampling and storage protocols to guarantee the representativeness of the analyzed CSRs. In addition, ISO 21646 specifies the methods for chemical and physical characterization of samples.

The minimum quantities required vary according to the technique used:

• For a carbon-14 analysis, a sample of 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 must demonstrate the sustainability of their energy sources. Highly energy-intensive, their activities are particularly exposed and controlled.
• Waste recycling: notably through the pyrolysis and gasification of bio-based materials. This sector is at the heart of environmental challenges.
• Agri-food: this sector uses bio-based 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 analytical laboratories in the Industry which use these methods and support teams in integrating them into their business processes.

The key role of analysis laboratories like CIRAM for manufacturers

It is in the interest of manufacturers to rely on specialized laboratories to guarantee the conformity of their RSCs and bio-based materials. Laboratory analysis provides accurate, usable results, facilitating certification processes and regulatory validation. As a leader in radiocarbon analysis, CIRAM supports manufacturers by providing them with reliable data to assess the bio-sourced content of their materials and thus ensure their compliance.

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

In this article, we will explore detection techniques, authentication methods, and the importance of laboratory analyses to guarantee the purity and traceability of essential oils. You will also discover why analyses such as carbon 14 and isotopic ratios help ensure the safety of your formulations.

Understanding the adulteration of essential oils

The adulteration of essential oils is a major issue for the food industry seeking 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 falsified products.

Definition and challenges of essential oil adulteration

The 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 these adulterations is much more significant than a simple drop in quality: it can lead to health risks for end-users as well as defects in the formulations of cosmetic or pharmaceutical products.

Industry professionals must understand that adulteration affects not only the performance of their products but also their compliance with current regulations. An adulterated essential oil can not only compromise the effectiveness of formulations but also pose health risks.

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 advantages for industrialists. It allows for a reduction in energy costs through the self-production of renewable energy, which reduces dependence on fossil fuels. Industrialists can also valorize their organic residues (food waste, sewage sludge, etc.) that would have been 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

Grants generally represent 10% of the funding sources for an industrial methanation project. Among existing grants, the methanation grant is one of the main support schemes for biogas production. Offered by various organizations, including ADEME and local authorities, it covers part of the investments related to the creation of methanation units. Since the launch of methanation in France, ADEME has financially supported over 150 projects. In 2020, it implemented a lump-sum approach to standardize access to its aid. In 2023, the lump-sum aid for biomethane injection projects is €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.
