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

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

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

Understanding forms of adulteration and classic detection methods

The compliance with 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 limits of classical detection methods in order to implement a plan of quality control rigorous.

Types of milk adulteration in the industry

Visit milk adulteration methods can take various forms that all respond to short-term economic logic, but whose consequences on product quality, health safety, and regulatory compliance are major.

The most common practices include :

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

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

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

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

Traditional test methods: between usefulness and limitations

Historically, the analysis of fraudulent milk relies on destructive methods or semi-quantitative ones requiring sample degradation. Among these are:

• The high-performance liquid chromatography (HPLC) which allows the detection of certain additives,
• Visit colorimetric tests, simple but insensitive analyses,
• Visit immunoenzymatic tests, which are more specific but slow.

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

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

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

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

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

Focus on non-destructive milk analysis techniques

Visit non-destructive analysis techniques are a concrete response to the challenges of modern quality control in the dairy industry. They indeed 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

Visit non-destructive techniques 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 the adulteration of milkThey 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?

Visit Milk adulteration testing techniques can prove complex for quality managers in companies. For professionals in charge of manufacturing processes, this requires a fine mastery of methods, particularly of non-destructive techniques, equipment, but also current standards, which is not their core competency. More and more of them are entrusting these analyses to a Expert laboratory in industrial production in order 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 analysisanalysis, an essential component of the science of dating, now offers a reliable, scientifically valid way of demonstrating theauthenticity of flavors at every stage of the industrial cycle, from component sourcing to the finished product.

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

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

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

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

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

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

CIRAM complies with international standards (ASTM D6866 and , 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?

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

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

Understanding the ISCC PLUS certification framework

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

Definition and scope of ISCC Plus certification

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

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

ISCC Plus defines strict principles:

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

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

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

Why has ISCC PLUS certification become strategic for manufacturers?

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

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

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

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

Obtain and maintain ISCC PLUS certification

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

The certification process: stages, costs, deadlines

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

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

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

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

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

Critical points: mass balance, traceability, food requirements

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

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

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

The role of laboratories and prospects for manufacturers

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

Support from specialized laboratories: a lever for compliance

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

CIRAM performs standardized analyses such as :

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

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

Maintain, enhance and anticipate the evolution of ISCC Plus certification

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

This includes :

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

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

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

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

The standard EN ISO 21644 defines 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 standard ISO 21644 recommend different analytical techniques and sample preparation to determine the bio-based fraction of a SRF:

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

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

Where to get analyze my CSR ?

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

CSR requirements and compliance with EN ISO 21644

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

Criteria for CSR

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

The minimum quantities required vary according to the technique used:

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

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

Sector challenges and applications for manufacturers

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

• Cement industry and thermal power plants : they have to demonstrate the sustainability of their energy sources. Highly energy-intensive, their activities are particularly exposed and controlled.
• Waste recycling : in particular via pyrolysis and gasification of bio-based materials. This sector is at the heart of environmental issues.
• Food industry : 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 industrial analysis laboratories that use these methods and support their teams in integrating them into their business processes.

The key role of analysis laboratories like CIRAM for manufacturers

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.

Visit solid recovered fuels (SRF) are an innovative solution adopted by industrialists to reduce their dependence on fossil fuels while valorizing the resulting waste. A true energy alternative, both economical and ecological, CSRs are 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 in this context that specialized laboratories such as CIRAM supports play a fundamental role. Thanks to their advanced analytical methods, these laboratories are able to accurately assess the chemical composition of RDF, its energy potential, and potential contaminants. They provide industry professionals with the advice and data needed to adjust their combustion processes and maximize efficiency while minimizing environmental risks.

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

Technical challenges of SRF for industry

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

Variability in RSC composition: a challenge for manufacturers

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

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

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

Importance of laboratory testing to guarantee CSR quality

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

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

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

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

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

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

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