Refuse-derived fuels (RDF) are an innovative solution adopted by industrialists to reduce their dependence on fossil fuels while valorizing waste. A true energy alternative, both economical and ecological, RDF is increasingly attracting 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 within this framework that specialized laboratories like CIRAM play a fundamental role. Thanks to their advanced analysis methods, laboratories are able to accurately assess the chemical composition of CSR, their energy potential, and possible contaminants. They provide industry professionals with the necessary advice and data to adjust their combustion processes and maximize their 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 carbon-14 analysis, in accordance with standard EN ISO 21644 (formerly EN 15440), which specifies the methods for determining the composition of CSRs. The analysis of the bio-based content also plays a role in compliance with European and international regulations on sustainable development. By mastering these aspects, manufacturers can thus meet the growing demands for CO2 emission reduction.

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 analysis laboratories like CIRAM is not limited to simple quality controls through composition analyses (bio-based content) but also extends to the regulatory level concerning current standards. By integrating solid recovered fuels into their energy strategy, industrial players have indispensable technical and scientific support to maximize the added value of these fuels while minimizing associated risks. This includes rigorous management of biomass content and biogenic carbon, essential for aligning industrial processes with environmental and regulatory standards. If you wish to benefit from the expertise of a laboratory specializing in SRF analysis, request a study of your samples from the CIRAM teams and obtain quality advice and analyses.

As the cosmetics market undergoes many changes, the demand for bio-based products continues to grow. For professionals in the cosmetics industry, it is essential to guarantee the authenticity and quality of their products, while avoiding the pitfalls of adulteration.

In this article, we explain how to identify the origin of biobased ingredients, the importance of cosmetics testing, and innovative solutions such as biosynthesis. Find out how to secure your production processes and meet consumer demands while complying with the most stringent standards.

Understanding biosourced cosmetics and their naturalness

Understanding the specifics of biobased cosmetics is now essential for professionals in this industry. In this section, we look at the fundamentals of bio-based cosmetics, highlighting the importance of naturalness and ingredient selection criteria in guaranteeing the integrity of products offered on the cosmetics market.

Biobased cosmetics and their benefits for industry

The term "biosourced cosmetics" refers to products formulated with ingredients of biological origin, derived from renewable sources. Unlike synthetic ingredients, these are obtained through environmentally-friendly processes such as plant extraction or fermentation. For manufacturers, the use of biosourced cosmetics offers strategic advantages. It is a viable response to growing consumer demand for more natural, sustainable products.

Cosmetic tests then play a fundamental role in ensuring that ingredients claimed as bio-based truly are. These analyses help reduce the risks of adulteration and non-compliance with expected certifications. Labels like COSMOS and Ecocert indeed guarantee the origin and quality of the raw materials used and are therefore sensitive for manufacturers.

The importance of naturalness and natural ingredients in cosmetics

The notion of naturalness in cosmetic products is a key criterion for the R&D departments of the cosmetic industry wishing to stand out in this competitive market. However, be aware: naturalness is not limited to the origin of the ingredients, but also includes their processing method. Naturalness tests thus make it possible to verify the absence of adulteration and the compliance of ingredients with regulatory requirements.

The distinction between natural and biobased ingredients is sometimes subtle, but it's crucial to understand it. A natural ingredient is one extracted directly from nature. A biobased ingredient, on the other hand, can be produced via processes such as biosynthesis, which enables the reproduction of rare compounds or those difficult to obtain in large quantities. The naturalness of our products is thus guaranteed by rigorous analysis, ensuring consumer confidence and regulatory compliance.

We have explored the foundations of biobased cosmetics and the importance of naturalness in formulations. In the next section, we'll explore the tools and methods for identifying the origin of biobased ingredients, and the importance of cosmetic testing in this process.

Identify the origin and guarantee the authenticity of biobased cosmetics

For manufacturers, ingredient traceability is an essential component for guaranteeing the quality and compliance of bio-based cosmetic products. In this section, we explore the tools available to the cosmetic industry for verifying ingredient provenance. We will also discuss the importance of cosmetic testing to ensure their authenticity.

Labels, certifications and databases to verify the origin of biobased ingredients

The use of recognized labels and certifications is essential to attest to the authenticity of bio-based ingredients. Labels such as COSMOS, Ecocert, and NATRUE offer guarantees on the origin of the raw materials used, ensuring they come from renewable and environmentally friendly sources. To obtain these labels, professionals not only validate the organic origin but also verify the sustainability and transformation practices of the ingredients.

There are also online databases like CosIng, or specialized platforms. These allow for checking the compliance of ingredients with current regulations. These tools are valuable for professionals wishing to quickly and efficiently validate the naturalness and traceability of the components used in their formulations.

The essential role of cosmetic testing in the validation and interpretation of natural and biobased ingredients

Cosmetic tests are a major pillar for ensuring the compliance of bio-based products with quality standards. These tests are carried out by specialized laboratories (such as CIRAM) and make it possible to validate the authenticity of declared ingredients and to detect any form of product adulteration. For example, the carbon 14 test is an effective method for distinguishing ingredients of natural origin from those of petro-sourced origin.

Interpreting cosmetic test results requires advanced technical expertise. It is essential for R&D departments to be able to understand analysis reports to ensure that products meet the requirements of labels and certifications. To achieve this, the best cosmetic testing laboratories offer manufacturers quality post-analysis support and continuous monitoring. These tests also make it possible to verify the absence of contaminants or non-compliant substances. This thus guarantees the safety and effectiveness of products placed on the market.

Having looked at the methods used to verify the origin of biobased ingredients and the importance of cosmetic testing to guarantee their authenticity, let's turn our attention to the risks of adulteration.

Prevent the risks of adulteration and explore alternatives via biosynthesis

Preventing fraudulent practices such as adulteration is essential for professionals in the cosmetics industry to guarantee the authenticity of ingredients. In this section, we'll look at the risks associated with adulteration, and discover why biosynthesis is an innovative solution for guaranteeing the quality of biobased cosmetics.

Adulteration of biobased cosmetics: risks and consequences for industry professionals

Adulteration of biobased cosmetic products is a real challenge for professionals in the cosmetics industry. This practice, which consists of partially or totally replacing a biobased ingredient with a component of inferior quality or synthetic origin, can have serious consequences. Adulteration can not only mislead consumers as to the naturalness of the product, but also compromise the safety and efficacy of the final product.

Cosmetic testing plays an essential role in detecting adulteration. For example, chromatographic and spectrometric analyses can identify the precise composition of ingredients and spot any fraudulent substitutions. Quality departments and the experts who work in them must be extremely vigilant in the face of these risks, in order to protect the brand's reputation while ensuring that product ranges comply with regulatory requirements.

Biosynthesis: an innovative alternative for guaranteeing the quality and durability of cosmetic ingredients

Although biosynthesis could be an innovative solution for the cosmetics industry, it actually represents a risk of adulteration for biobased products. A majority of industry professionals seek to distinguish between genuinely natural products and those derived from biosynthetic processes. The latter, although technically derived from organic raw materials, do not correspond to the expectations of naturalness and "botanicity" sought by consumers and quality labels.

Advanced analytical techniques, such as isotope profiling, are essential to identify biosynthetic ingredients and guarantee product authenticity. In particular, the CIRAM laboratory uses methods based on the analysis of stable isotopes of carbon (δ13C), hydrogen (δ2H), oxygen (δ18O) and nitrogen (δ15N). These isotopes make it possible to establish the botanical or geographical origin of ingredients, but also to detect adulteration by biosynthetic products. For example, analysis of δ13C values can differentiate vitamin C extracted from natural sources such as acerola, from that synthesized from glucose.

Although these analyses are mainly qualitative and not quantitative, they nevertheless provide valuable information for detecting cases of adulteration and guaranteeing the true "naturalness" of products. Cosmetic tests using the coupling of several isotopes enable us to pinpoint the origins of ingredients in much greater detail. This method is an invaluable asset for professionals in the biosourced cosmetics industry, who are keen to comply with quality and naturalness standards for the ingredients in their products.

Biosourced cosmetics therefore represent a major step forward for the cosmetics industry, providing a viable response to the growing demand for naturalness and sustainability. However, guaranteeing the authenticity and quality of ingredients remains a major challenge, given the risks of adulteration and the complexities of ingredient traceability.

Cosmetic testing, carried out by specialized laboratories such as CIRAM, is essential for validating the origin and conformity of products. Thanks to rigorous methods and cutting-edge technology, CIRAM supports professionals from the request for a study through to post-analytical follow-up, to ensure that products are reliable and compliant.

For industry professionals, the composition of paints is of paramount importance. Whether for applications in automotive, aeronautics, or other manufacturing fields, the properties of paints are determined by their chemical composition.

In this article aimed at industry professionals, we will explore the different components of industrial paints, the categories of paints based on their composition with a focus on bio-based paints. We will continue with the importance of chemical analysis and the impact of chemical composition on the performance and use of paints.

General composition of industrial paint

The main paint components

Industrial painting consists of four main elements:

• pigments,
• binders,
• solvents,
• and additives.

These components have different impacts on manufactured products:

• The pigments are responsible for the color and opacity of the paint. There are organic or inorganic pigments. These each have specific properties of resistance to UV, heat, and chemicals.
• The binders form the paint film and determine the mechanical properties of the paint, such as its hardness and adhesion. Binders can be oil-based (alkyds), latex-based (acrylics), or epoxy resins (among others).
• Solvents are used to adjust the viscosity of the paint, which facilitates its application. Volatile solvents such as aromatic hydrocarbons or alcohols are commonly used. However, their use is regulated due to their environmental impact.
• Additives are minor components that are part of industrial paints. They improve certain properties of the paint, such as mold resistance, UV stability, or improved drying time. Anti-sagging agents and corrosion inhibitors are essential additives for industrial applications.

The composition of paints is therefore determined by the addition of different components. The choice of these components determines the category of paint.

Paint categories by composition

There are several categories of industrial paints. These are determined by their composition and each meets particular uses:

• Solvent-based paints: they are traditionally used for their fast drying time and durability. This category is declining due to environmental concerns and VOC regulations (volatile organic compounds). Environmental regulations imposed on companies are forcing manufacturers to turn to other categories to limit the impact of paints on the environment.

• Water-based paints: they are increasingly popular due to their low VOC content. These are often used in sensitive environments such as food production facilities and hospitals. However, their chemical composition makes them less resistant, which limits their range of applications.

• Powder coatings: they are applied in dry powder form and then cured at high temperature. These coatings offer excellent wear resistance and are solvent-free, making them environmentally advantageous. Their field of application is therefore wider than water-based coatings.

• Bio-based paints: bio-based paints are made from renewable raw materials. They represent a major step forward towards more sustainable industrial production, more environmentally friendly without compromising their technical performance.

It is crucial for professionals in the manufacturing industry to have a good understanding of the different industrial paint compositions. This allows R&D departments to select the products best suited to their specific needs while respecting their environmental and regulatory constraints in their manufacturing processes.

Bio-based paints are a category of paints that are particularly relevant for manufacturers to cope with new regulatory constraints. Let's take a closer look at them.

Biosourced paint: a sustainable and ecological choice

Bio-based paintsare gaining popularity among manufacturers due to their environmentally friendly composition. Indeed, they offer a sustainable alternative to traditional paints, while meeting the performance requirements of industrial applications.

What is the specific composition of biosourced paint?

The composition of bio-based paints incorporates various sustainable ingredients:

• Bio-based binders are resins that primarily come from linseed, soybean, or castor oil. These binders offer performance similar to synthetic resins while being biodegradable.
• Natural pigments are extracted from minerals or organic matter. They provide a durable and stable coloring role without being toxic.
• Eco-friendly solvents and bio-based paints use water-based solvents or natural alcohols. This usage helps reduce VOC emissions and improve safety during application.
• Bio-based additives (such as beeswax or plant extracts) improve various properties of paint.

These natural additives enhance water and scratch resistance, while remaining environmentally friendly.

There are several chemical analysis techniquesfor evaluating the composition of paints:

• Radiocarbon analysis (C14)

Radiocarbon analysisaccording to NF EN 16640 standardis used to identify the presence or absence of natural products in paint. The concentration of carbon 14 indicates the content of biobased products: the more carbon 14 the paint contains, the more natural products it contains.

This is an essential technique for analyzing thecomposition of bio-based paints.

• Infrared spectroscopy (IR)

Infrared spectrometry analysis is used to identify the chemical bonds and functional groups present in the paint. This technique allows for the characterization of binders and additives.

• Gas chromatography (GC)

Gas chromatography is essential for analyzing volatile solvents and additives. It allows for the separation and identification of organic compounds present in paint.

• Mass spectrometry (MS)

Mass spectrometry is often coupled with chromatography because it allows for the identification and quantification of chemical components at very low levels. It provides a detailed analysis of the composition.

• X-ray fluorescence (XRF)

Xfluorescenceis a non-destructive method used to determine the elemental composition of pigments and mineral fillers. It is a fast and accurate technique for the analysis of metallic or mineral elements.

Biosourced paint chemical analysis laboratories

Specialized laboratories for the analysis of bio-based paints play a key role in the development and optimization of these ecological products.

They use cutting-edge technologies to perform complex analyses, which guarantees the quality and performance of bio-based paints. The choice of a paint and pigment analysis laboratory is essential for manufacturers.

Biofuels offer a promising alternative to fossil fuels. However, this alternative is not yet the norm in industrial processes. To better assess their importance, you need to understand the role of biogenic carbon.

• Why is it crucial to quantify this carbon in biofuels?
• How does this help reduce CO₂ emissions and achieve sustainability goals?

This article is intended to provide industry professionals with information and clear answers on the importance of this quantification.

The importance of quantifying biogenic carbon in biofuels

Definition and role of biogenic carbon in biofuels

Biogenic carbon, or biogenic carbon, is essential in biofuels. Derived from renewable organic matter such as agricultural residues and forest waste, it differs from fossil carbon originating from non-renewable sources like oil.

Biofuels such as biodiesel, biogas, and SAFs (Sustainable Aviation Fuels) use biogenic carbon. This carbon, captured by plants through photosynthesis and released during combustion, completes a cycle without adding extra CO₂ to the atmosphere. This process reduces the carbon footprint and helps achieve sustainability and greenhouse gas emission reduction goals.

Implication of biogenic carbon in the emission of biogenic CO₂

Accurate quantification of biogenic carbon in biofuels is crucial for assessing the environmental impact of these fuels. Biogenic CO₂, emitted during the combustion of biofuels, differs fundamentally from fossil CO₂.

While fossil CO₂ contributes to rising atmospheric CO₂ levels on a permanent basis, biogenic CO₂ is part of a short cycle where it is reabsorbed by plants as they grow.

For industry professionals, understanding this distinction is crucial. Not only will it enable you to optimize biofuel production processes, it will also ensure compliance with environmental regulations and sustainability certifications.

As an example, in the context of SAF and e-fuel production, the quantification of biogenic carbon is essential to demonstrate that these fuels meet reduced CO₂ emission criteria, thus promoting their adoption in the aviation industry.

Let's take a look at the environmental implications of biogenic carbon. What is its impact on global warming, and what role can it play in protecting our environment?

The environmental implications of biogenic carbon

The impact of biogenic carbon on climate change

Biogenic carbon, in its use as biofuel, plays a crucial role in efforts to limit global warming. While fossil carbon increases atmospheric CO₂ concentrations by releasing carbon stored for millions of years, biogenic carbon participates in a short carbon cycle. This cycle reduces the overall carbon footprint of fuels.

So, although biofuels such as biodiesel, biogas, or SAF (Sustainable Aviation Fuels) emit biogenic CO₂ during combustion, this is largely offset by the CO₂ absorbed by plants during their growth.

This cycle then helps to maintain a balance in atmospheric carbon and limit the effects of the greenhouse effect, thus helping to slow global warming.

The importance of reducing fossil CO₂ for environmental protection

Reducing fossil CO₂ emissions is essential to protect the environment and promote sustainable development. Today, optimizing biofuel production and use methods to minimize emissions is therefore a priority for manufacturers.

As a result, it has become essential for manufacturers to implement rigorous standards for quantifying biogenic carbon. As we have seen, these standards make it possible to guarantee that the biofuels produced meet environmental requirements. This is why biofuel certifications and eco-labels are rightly based on strict biogenic carbon content criteria.

The adoption of biofuels with an optimized carbon footprint can play a major role in the global energy transition. Sectors such as aeronautics can thus hope to reduce their dependence on fossil fuels and cut their CO₂ emissions. An essential subject for this sector regularly put under pressure by civil society.

Reducing fossil CO₂ through the use of well-quantified and optimized biofuels is therefore a key strategy for meeting current and future environmental challenges. Let's now look at how biogenic carbon is used in different types of biofuels, such as biodiesel, biogas, and SAF (Sustainable Aviation Fuels).

The use of biogenic carbon in different types of biofuels

Biogenic carbon in biodiesel

Biodiesel is one of the most commonly used biofuels, and is largely based on biogenic carbon. Produced from renewable sources such as vegetable oils and animal fats, biodiesel contains carbon captured by organisms as they grow. This carbon is then released during combustion, completing the biogenic carbon cycle.

Accurate quantification of biogenic carbon in biodiesel is essential for determining its environmental impact. By measuring the proportion of biogenic carbon, manufacturers can optimize their processes to maximize efficiency and minimize CO₂ emissions. This also helps meet regulatory requirements, enabling companies to benefit from carbon credits or other ecological advantages.

Biogenic carbon in biogas

Biogas is another important biofuel that takes advantage of biogenic carbon. Derived from the anaerobic decomposition of organic matter such as agricultural waste, food residues and sewage sludge, biogas is a renewable energy source that can be used in a variety of ways: to generate heat, electricity or as a vehicle fuel.

The use of biogenic carbon in biogas offers several environmental advantages. By capturing and reusing methane, biogas contributes to the reduction of overall greenhouse gas emissions. Furthermore, the quantification of biogenic carbon in biogas helps ensure that these emissions remain within acceptable limits and also that biogas remains a green alternative to fossil fuels.

Biogenic carbon in SAF (Sustainable Aviation Fuel)

SAF, or Sustainable Aviation Fuel, represents a major step forward for the aviation industry in its quest to reduce its impact. Made from a variety of biomass sources, including waste oils and agricultural residues, SAF integrates biogenic carbon into its life cycle. In this way, it significantly reduces CO₂ emissions from aviation, a sector heavily dependent on fossil fuels.

For SAF manufacturers and consumers, quantifying biogenic carbon is essential. It helps demonstrate that fuels meet stringent sustainability and CO₂ emissions standards. Thus, by optimizing biogenic carbon content, SAF manufacturers can improve fuel efficiency and reduce the overall carbon footprint of their products. An essential aspect for airlines seeking to reduce their environmental impact and comply with increasingly stringent international regulations.

The use of biogenic carbon in different types of biofuels, whether biodiesel, biogas, or SAF, therefore plays a central role in promoting renewable and sustainable energy sources. By quantifying and optimizing this carbon, industrialists can not only improve their environmental performance but also contribute significantly to the fight against climate change.

Having explored the use of biogenic carbon in various biofuels, we now turn our attention to the evolution of biofuels with the emergence of e-fuel and its production process.

The evolution of biofuels: the importance of e-fuel

What is e-fuel and how is it produced?

E-fuel, or synthetic fuel, is a first-rate innovation in the field of biofuels. Unlike traditional biofuels, e-fuel is produced from hydrogen and CO₂, captured either directly from the air or from industrial sources. The e-fuel production process requires the use of electricity to electrolyze water and produce hydrogen. The hydrogen is then combined with the captured CO₂ to synthesize various types of fuel, such as gasoline, diesel or kerosene.

Synthetic fuels therefore offer several advantages, including the possibility of reducing CO₂ emissions and using existing infrastructure for fossil fuels. Indeed, these synthetic fuels are chemically similar to conventional fuels. This similarity facilitates their adoption without requiring major modifications to engines or distribution systems. A transformation towards a use of synthetic fuels that MotoGP is in the process of adopting.

The role of biogenic carbon in e-fuel production

Biogenic carbon plays an essential role in e-fuel production as it provides a renewable and sustainable source of CO₂. By using biogenic CO₂, captured from biomass or biological processes, e-fuel producers can create a closed carbon cycle. This means that the CO₂ used to produce e-fuel is that previously absorbed by plants, reducing the fuel's net carbon footprint.

For manufacturers, the quantification and integration of biogenic carbon in e-fuels are critical aspects. These analyses make it possible to certify that e-fuel is truly sustainable and does indeed contribute to reducing overall CO₂ emissions. On the other hand, by optimizing the use of biogenic CO₂, industrial companies can improve the efficiency of their production processes and increase the economic viability of e-fuel.

E-fuel thus represents a promising technological advance in the development of biofuels as a sustainable alternative, while at the same time being compatible with existing infrastructures. The role of biogenic carbon in this context is essential, as it ensures that these new synthetic fuels make an effective contribution to reducing greenhouse gas emissions and combating climate change.

Future prospects for biogenic carbon quantification

The challenges of accurately measuring biogenic carbon in biofuels

Precise quantification of biogenic carbon in biofuels poses a number of challenges. One of the main obstacles is the complexity of the biomass sources used to produce these fuels. Feedstocks can vary considerably in their chemical composition and biogenic carbon content. This makes standardization difficult.

On the other hand, the processes involved in transforming and converting biomass into biofuels can alter the chemical structure of biogenic carbon, further complicating quantification methods. For quality departments, developing robust protocols that can adapt to these variations while guaranteeing reliable, reproducible results remains crucial.

Regulatory constraints and certification requirements also add a layer of complexity. Biofuels must meet stringent standards to be considered sustainable, requiring precise quantification of biogenic carbon to prove compliance.

Technological advances in biogenic carbon quantification

To meet these requirements, significant technological advances have been made to improve the quantification of biogenic carbon. Mass spectrometry, in particular, enables the precise determination of biogenic carbon content. Laboratories such as those at CIRAM support manufacturers in the analysis and certification of components.

For R&D departments and regulatory authorities, these technical advances offer new opportunities to strengthen quantification methods and guarantee the sustainability of biofuels.

Finally, although the accurate measurement of biogenic carbon in biofuels presents significant challenges, technological advances offer promising solutions. These innovations improve the accuracy of analysis and ensure that biofuels meet sustainability standards, contributing to a greener, more efficient energy transition.

To conclude, quantifying biogenic carbon in biofuels is therefore essential to ensure their sustainability and effectively reduce CO₂ emissions. We have seen that biogenic carbon, derived from renewable sources, plays a crucial role in the life cycle of biofuels such as biodiesel, biogas and SAF. E-fuel also represents a major step forward, thanks to its innovative production process. Despite measurement challenges, technological advances offer promising solutions for accurate quantification.

In a context where sustainability and environmental responsibility have become key priorities, bioplastics are emerging as a promising opportunity for companies.

However, the credibility and transparency of the environmental claims associated with these materials depend heavily on certifications and labels.
In Europe, two labels stand out in particular: “OK Biobased” and “DIN CERTCO.”These certifications play a key role not only in ensuring compliance with environmental standards but also in building trust among consumers and business partners.

For industry professionals, understanding and integrating these labels into their day-to-day work is essential.

In this article we explore in depth the current and future impact of these labels on the European biobased plastics market. We also explain why it's crucial for these experts to familiarize themselves with these certifications. You'll discover how these labels can foster innovation, optimize manufacturing processes, guarantee product quality and ensure regulatory compliance.

Labels for bioplastics and biopolymers

The importance of labels for biobased products

The labels simply certify that the product is made from renewable organic materials. It's a way for producers to demonstrate their commitment to producing products with low environmental impact. In other words, when a product bears one of these labels, it guarantees that it has been manufactured with respect for the environment.

Bioplastics and biopolymers represent a significant step forward for the plastics industry. This ecological and sustainable choice could well be an advantage for market players wishing to be pioneers in complying with future environmental standards. The objective for manufacturers is to integrate these materials as early as possible in order to gain a major competitive advantage in the future.

These labels are therefore a crucial tool for consumers and business partners alike, since they can be used to display a product's quality and environmental credentials.

Now that we've defined the importance of these labels, it's time to analyze their specific characteristics.

OK Biobased" label

The "OK Biobased" label is a certification awarded by TÜV Austria that guarantees the percentage of bio-based material in a product. It aims to quantify the proportion of renewable raw materials used in the manufacturing of bioplastics.

It uses a star rating system, ranging from 1 to 4 stars, to indicate the proportion of renewable raw materials used. Each star represents a certain percentage range of biobased material:

• 1 star: 20-40% renewable materials
• 2 stars: 40-60% renewable materials
• 3 stars: 60-80% renewable materials
• 4 stars: over 80% renewable materials

This certification is particularly useful for companies wishing to demonstrate their commitment to the environment. This label is often used in the production of bioplastics.

DIN CERTCO" label

DIN CERTCO, a subsidiary of TÜV Rheinland, offers various certifications, including one for bioplastics. The DIN CERTCO label for bioplastics certifies products based on their biodegradability and compostability. DIN CERTCO certifications are based on European standards EN 13432 and EN 14995. The criteria include:

• Biological degradation in an industrial composting environment
• No toxic residues after decomposition
• Physical disintegration within a specified timeframe
• The quality of the resulting compost

This label is essential for companies wishing to guarantee that their products are not only biobased but also capable of biodegrading efficiently, thus responding to concerns about environmental impact and waste management regulations.

This certification ensures that the plastic is biodegradable and decomposes under industrial composting conditions without leaving harmful residues.

What impact do bioplastics labels have on the European market?

The European market for bioplastics and biopolymers is growing fast, fueled by growing environmental concerns and stricter regulations on traditional plastic materials.

In this context, the "OK Biobased" and "DIN CERTCO" labels play an essential role in guaranteeing the credibility and transparency of the ecological claims made for bioplastic products.

We're going to analyze the impact these labels have had on markets and companies' capacity for innovation.

OK Biobased: promoting renewable materials

The "OK Biobased" label has had a significant impact in encouraging manufacturers to increase the proportion of renewable raw materials in their products. By awarding certification based on the percentage of biobased content, this label has encouraged companies to invest in more sustainable materials and develop alternatives to fossil-based plastics.

Companies' R&D departments have thus been motivated to explore new biomass sources and improve production processes to achieve higher levels of certification.

For process engineers and quality managers, this label offers a means of differentiating their products in an increasingly competitive market, by highlighting their commitment to the sustainability of their products.

DIN CERTCO: guaranteeing biodegradability and compostability

The DIN CERTCO label has played a crucial role in setting clear standards for the biodegradability and compostability of bioplastics. By certifying that certified products break down efficiently under industrial composting conditions, DIN CERTCO certification has helped overcome initial mistrust concerning the environmental impact of bioplastics.

For regulatory authorities, DIN CERTCO offers assurance of compliance with European standards such as EN 13432, EN 16640, and EN 14995, which are often required for product approval in the market.

By validating the compostability of products, this label has also helped municipalities and waste managers integrate bioplastics into organic waste management systems, enabling companies to take another step towards a circular economy.

The "OK Biobased" and "DIN CERTCO" labels therefore have an impact on both companies and markets. They boost consumer and business confidence by providing greater transparency on the environmental claims of bioplastics products. Confidence is essential to the widespread adoption of bioplastics, as it helps overcome skepticism and promotes a transition to more sustainable materials.

But what does the future hold for bioplastics and biopolymers labels in Europe? Will they evolve to better meet the expectations of institutions and consumers? Will regulations evolve? Let's take a look at the future of these certifications at European level.

The future of bioplastics labels in Europe

As Europe continues to strengthen its environmental policies and demand for sustainable materials increases, the future of bioplastics labels looks bright. The "OK Biobased" and "DIN CERTCO" labels will play an even more crucial role in ensuring the transparency, credibility and compliance of biobased plastic products.

Evolving standards and regulations

Reinforced requirements

With the introduction of new European directives on plastics and packaging, the requirements for obtaining certifications such as "OK Biobased" and "DIN CERTCO" are likely to become more stringent. This will force companies to adopt more sustainable production practices and invest more in the research and development of new biobased and biodegradable materials.

European legislation on plastic bags, which must contain at least 50% of

carbon by 2020 and 60% by 2025

To ensure compliance with these regulatory requirements, it is crucial for companies to engage in an innovation process, by carrying out biopolymer and bioplastic analysis studies. Companies that have already integrated these materials will therefore gain a head start on the rest of the market, thus ensuring sustainable growth while lowering their production costs.

Harmonizing standards

In the future, we are likely to see increased harmonization of certification standards across Europe, facilitating cross-border trade in certified biodegradable plastic products. This harmonization will also enable mutual recognition of labels between different countries, reinforcing the credibility of certifications and simplifying regulatory processes for companies.

Technological innovations and new labels

New materials and technologies

Technological advances in bioplastics will continue to emerge, leading to the creation of new materials with improved properties. In response, certification bodies will need to adapt their criteria and perhaps even create new labels to accommodate innovations, such as bioplastics with additives for specific functionalities (e.g. UV resistance or controlled degradation).

Multiple specialized labels

In the future, we may see the emergence of more specialized labels that focus on particular aspects of bioplastics, such as carbon footprint, recyclability, or decomposition in marine environments. As these issues are at the heart of current discussions concerning the protection of living organisms, they are likely to lead to new regulatory requirements for biosourced polymers. These specialized labels will provide precise, relevant information for organizations concerned about the environmental impact of their products.

Impact on consumers and the market

Awareness-raising and education

As environmental awareness increases among consumers - from an early age - bioplastics labels will play a key role in educating the public about the benefits of biosourced and biodegradable materials. Information campaigns and educational initiatives could be launched to explain the meaning of labels and encourage responsible consumer choices. Integrating these materials and labels today will enable companies to make tomorrow's profits and meet future market requirements.

Growing demand and consumer pressure

Consumer pressure for more sustainable products will continue to grow in the future. This will force companies to comply with biobased plastics labels to remain competitive. Labels will thus become a determining factor in purchasing decisions, directly influencing companies' market strategy.

All the indicators are therefore green for the future of bioplastics and biopolymers. Environmental issues and their transposition into regulatory standards will drive companies to integrate these materials into their processes, enabling them to lower their production costs. This will enable them to meet market and consumer demands, while at the same time working on their CSR policies.

The "OK Biobased" and "DIN CERTCO" labels are therefore much more than simple certification marks; they are catalysts for transformation for the bioplastics industry in Europe. By promoting the use of renewable raw materials and guaranteeing the biodegradability and compostability of products, these labels play an essential role in the transition towards a more sustainable economy.

Whether you work in an R&D department, on your internal processes, in the quality department or on the regulatory aspect of your activities, knowledge of these certifications is crucial. Not only does it enable you to meet regulatory requirements and consumer expectations, it also stimulates innovation, optimizes manufacturing processes and boosts your company's competitiveness in the marketplace. Bioplastics and biopolymers analysis and study laboratories like CIRAM can help you in this innovation process.

As Europe continues to move towards stricter environmental standards, understanding and integrating the "OK Biobased" and "DIN CERTCO" labels is becoming essential. By adopting these certifications, companies can ensure that their products are not only compliant, but also at the cutting edge of sustainability. These labels are therefore a clear solution for navigating a complex regulatory landscape driven by corporate environmental and CSR issues.

The same applies to the analysis of isotopic ratios of carbon, nitrogen, oxygen and hydrogen (δ13C, δ15N, δ18O and δ2H). Their analysis will provide information on the diets of ancient populations and the geographical or botanical origins of agri-food products.

Stable isotope analysis with IRMS

The technique dedicated to the study of stable isotopes is IRMS, isotope ratio mass spectrometry. We measure the ratios of stable isotopes such as 13C/12C, 15N/14N, 2H/1H and 18O/16O. Measurements are compared with international references, considered as "zero points": for carbon, this is the Vienna Standardized Peedee Belemnite (VPDB), for nitrogen it's air, and for hydrogen and oxygen it's the Vienna Standardized Mean Ocean Water (VSMOW). CIRAM laboratories use a vario ISOTOPE select elemental analyzer (EA) and an IRMS Isoprime precisION from ELEMENTAR.

Distortions in plant isotope ratios

It is the different types of photosynthesis that are responsible for distortions in plant isotope ratios. For example, woody trees, barley, rice and beans (C3 plants) have a d13C carbon isotope ratio of less than -20 ‰, while maize, sorghum and sugar cane (C4 plants) have a d13C of between -10 and -20 ‰. It's the presence of nitrogen in proteins that will provide information on their origin: terrestrial or marine. By coupling the study of carbon and nitrogen isotopes, we can define the diet of an individual or animal: carnivorous, herbivorous or omnivorous; and the origin of its diet: terrestrial or marine.

Industrial applications of stable isotope analysis

In industry, stable isotope analysis is used for product authentication in general, and in particular to verify provenance, identify adulteration or define the original raw material for biofuel production, for example.

The stable isotopes of carbon will be used to identify the adulteration of honey with corn-derived fructose syrup. Corn, a C4 plant, has a d13C between -20 and -10‰, whereas authentic honey has a δ13C below -23.5‰. A d13C measurement above -21‰ will indicate adulteration. Carbon isotopic ratios will also allow the identification of "real" apple cider vinegar with a δ13C around -25‰, while apple cider vinegar adulterated with biosynthetic acetic acid will have a δ13C around -10‰.

Adulteration of fruit juice or wine can be detected by studying stable oxygen isotopes. The δ18O value of the adulterated product will be negative, while that of the pure products will be positive.

Stable hydrogen isotopes will be used to differentiate between two C3 plants: orange and beet, for example. An orange juice adulterated with beet sugar will have a δ2H around -50‰, while authentic orange juice will have a δ2H between -40 and -13‰.

Stable isotope analysis is a very important source of information on ancient dietary habits, botanical origins and the authentication of raw materials. But these are qualitative techniques only. In most cases, it will be essential to couple these studies with carbon-14 dating or radiocarbon analysis, in order to obtain chronological information or quantify adulteration.

CIRAM, a laboratory for isotopic analysis and carbon 14 dating since 2005, assists you in addressing your archaeological and industrial challenges.

Radiocarbon analysis (or carbon-14 dating) is a scientific technique that has revolutionized our understanding of ancient and modern materials. This type of analysis is widely used in the fields of art and archaeology. It is now increasingly used for industrial applications such as paint and pigment production. 

Growing environmental concerns are driving manufacturers to develop new, more sustainable products. Their manufacture requires a distinction to be made between bio-based materials, derived from biomass, and petro-sourced materials. petrosourced materials. 

In this article, we explore how radiocarbon analysis, combined with the study of volatile organic compounds and modern analytical techniques can be used to assess the composition of industrial paints. You'll also discover the challenges associated with this method and the promising innovations innovations.

Introduction to radiocarbon analysis of paints and pigments

Definition and importance of radiocarbon analysis

Radiocarbon analysis (or carbon-14 dating) is a scientific method used to determine the age of carbon-containing materials. carbon-14 is an unstable isotope that decomposes over time (with a half-life of halflife of 5730 years). Based on this this half-lifelife that carbon-14 dating laboratories dating laboratories can estimate the age of organic materials.

In the context of paints and pigments, this method is used to identify the proportion of biogenic carbon (derived from biomass) and fossil carbon (petroleum-based).

Link between radiocarbon analysis and biobased paint

The bio-based paints are made from renewable components of plant or animal origin. They therefore contain a significant proportion of biogenic carbon. Radiocarbon analysis is therefore essential to quantify this composition and verify the proportion of natural materials in the paints.

This paint analysis method is particularly relevant for manufacturers striving to reduce volatile organic compound (VOC) emissions and improve air quality.

What's more, the production of bio-based paints is part of an ecological approach aimed at minimizing environmental impact. In fact, bio-based materials have the advantage of of being derived from renewable renewable sources. This enables the industry to reduce its dependence on fossil fuels and reduce the carbon footprint of paint production. The use of radiocarbon analysis can certify the presence and proportion of biogenic carbon, offering a guarantee of transparency and compliance with environmental standards.

Exploring different analysis techniques for industrial paints

Analysis of traditional industrial paints

The industrial paints, which are often used in construction, generally contain pigments and organic binders derived from fossil materials.

Radiocarbon analysis plays a key role in differentiating between components of fossil origin and natural materials. For manufacturers, it is essential to understand this distinction in order to reduce the use of petrochemical-based compounds and improve the environmental footprint of their products.

Study of modern bio-based industrial paints

The developments undertaken by manufacturers to improve the durability of their products have resulted in a major increase in the use of biosourced components. These bio-based paints use pigments and binders made from renewable raw materials, such as vegetable oils or natural resins. 

For this, radiocarbon analysis is crucial to determine the proportion of biogenic carbon present in these products, and thus guarantee their compliance with environmental standards and obtain ecological certifications (such as obtaining the "Biosourced Product" label label, for example).

Radiocarbon analysis also enables manufacturers to confirm the durability criteria of their paints and pigments paints and pigments to meet the growing demand for environmentally-friendly industrial products.

Importance and methodology of air quality in paint analysis

The role of volatile organic compounds in air quality

The COV (Volatile Organic Compounds) are chemical substances that evaporate easily at room temperature and can have a significant impact on indoor air quality. In the case of paints, these compounds often originate from solvents and additives used. Radiocarbon dating of bio-based paints then makes it possible to check if they emit less VOCs compared to traditional paints and thus contribute to better air quality.

Reducing VOC emissions is important not only for the environment, but also for human health. Prolonged exposure to VOCs can lead to a variety of health problems, from respiratory irritation and headaches to more serious effects such as liver damage and hormonal disruption.

It is therefore crucial for manufacturers to develop industrial paints formulated with low VOC emissions. Thanks to radiocarbon analysis of paints, manufacturers can have their bio-based paints certified as low-VOC.

These products will thus meet the requirements of increasingly stringent environmental regulations and satisfy the growing demand for healthier, environmentally-friendly products.

The future of radiocarbon analysis of paints and pigments

Recent and future innovations in paint analysis

The accuracy and reliability of radiocarbon measurements are continually being improved by laboratories using new technologies, such as the particle gas pedal coupled to a mass spectrometer (AMS). The use of AMS has truly revolutionized the field, enabling the detection of extremely low levels of carbon-14, even in samples of just a few mg.

Innovation continues to non-destructive techniques, like the infrared spectroscopy and Raman spectroscopy, has also transformed the analysis of industrial paints. These technologies indeed make it possible to determine the The chemical composition of paints and pigments without requiring any samples. This innovation is essential to ensure the quality control eand manufacturing process optimizations. These methods indeed offer rapid and precise diagnostics of chemical components, allowing manufacturers to quickly identify and correct formulation defects.

More recently, the integration of artificial intelligence and machine learning algorithms into data analysis is also modernizing industry practices. These technologies can detect anomalies and optimize formulations to improve the durability and performance of industrial paints.

The role of carbon-14 analysis laboratories for paints and pigments

Specialized laboratories, such as lCIRAM Laboratories, play a vital role in the analysis and certification of paints and pigments. By providing accurate data on the composition of materials, these laboratories enable manufacturers to validate their products by verifying compliance with quality and safety standards.

They also play a crucial role in verifying the presence of bio-based components, helping to certify products as environmentally friendly. This expertise is essential for companies seeking environmental certifications, such as ecolabels, which demonstrate a commitment to sustainable, environmentally-friendly practices.

Radiocarbon dating of paints and pigments therefore represents a major advance in understanding the composition of bio-based industrial products. As demand for greener products continues to grow, the role of specialized laboratories, such as CIRAM, becomes increasingly crucial. By combining science and process innovation, radiocarbon dating contributes to a future where sustainability is at the heart of industrial production.
