ANALYSIS OF RECYCLED PRODUCTS

— On-site and Laboratory Interventions —

Circular economy is gaining importance globally, and with it, the use of recycled raw materials is becoming more and more common. However, before these recycled materials can be reused in the manufacturing of new products, it is crucial to ensure their quality and safety. This is where physico-chemical analyses play an essential role in the recycling process.

At OSE Industries, our experts address these issues on-site or in the laboratory to provide you with the appropriate answers to your questions:

PHYSICO-CHEMICAL CHARACTERIZATION AND TESTING TO ENSURE THE SAFETY OF RECYCLED PRODUCTS

What strategies to verify the safety of recycled materials?

One of the first steps in analyzing recycled materials is to verify their formulation.

  • This means determining the chemical and physical composition of the recycled raw material using suitable analysis techniques.
  • In the case of recycled plastics, it is crucial to know the type of plastic (PET, HDPE, PVC, etc.)
  • Ensuring there are no unwanted contaminations, such as other types of plastics or additives.

Why and how to search for Heavy Metals in recycled products?

The presence of heavy metals in recycled materials can pose risks to human health and the environment, and lead to regulatory non-compliance (Directive RoHS No. 2015/863, Toy Directive No. 2009/48/EC, REACH Regulation No. 1907/2006, Packaging and Waste Directive No. 94/62/EC...)

  • Physico-chemical analyses allow the detection of heavy metals such as lead, mercury, cadmium, and hexavalent chromium.
  • The levels of these metals must comply with safety standards to ensure that products made from recycled materials do not pose unnecessary risks.

What products to search for in recycled materials?

Recycled materials may contain potential contaminants. This can result from environmental pollution or inefficient recycling processes. Physico-chemical analyses are essential to identify these contaminants and take appropriate measures to eliminate or reduce them to safe levels.

  • This can include contaminants such as chemical residues,
  • microplastics, or other undesirable substances, particularly pollutant emissions from the environment or recycling processes.

What techniques are used for the analysis of recycled materials?

  • ICP-MS technique: analysis of heavy metals, pollutants
  • RAMAN, FTIR, Py-GC/MS technique: confirmation of polymer nature
  • NMR technique: characterization of unknown products
  • Isotopic analysis technique: verification of the recycled nature of the material

These techniques are essential for identifying and quantifying these exogenous elements.

STUDY OF TECHNICAL PERFORMANCE OF RECYCLED RAW MATERIALS (RRM)

What are the challenges related to the use of Recycled Raw Materials (RRM)?

The use of RRMs, although sustainable, presents significant challenges in terms of performance and reliability. Indeed, recycling cycles can alter the mechanical properties of materials, affecting their strength, elasticity, and durability. Recycled fibers may become more fragile, less effective, or show quality variations from one batch to another, making it difficult to ensure consistent performance. It is therefore crucial to rigorously assess these materials to ensure they meet the technical requirements of your products.

OSE SERVICES Expertise

To assess the technical performance of these materials, OSE SERVICES assists you in the physical and chemical characterization of your recycled products. Our tests include:

  • Analysis of mechanical properties (tensile tests, drop tests…)
  • Durability (aging in climatic chambers)
  • Resistance to stress
  • Compliance with current standards

ensures that you can guarantee optimal quality products while meeting environmental and regulatory expectations.

THE LEGISLATION OF RECYCLED RAW MATERIALS (RRM) AND CLAIMS

How to verify the traceability of Recycled Raw Materials (RRM)?

  • Traceability and Transparency:

One of the main challenges with RRMs is ensuring complete traceability. Knowing the origin of the recycled materials, their collection process, and their treatment is essential to ensure they meet quality standards and regulations. Traceability enhances transparency and trust throughout the supply chain, reducing the risk of non-compliance.

  • Caution on Recycled Product Claims:

The mass balance method allows certification of the proportion of recycled materials without strict separation of flows, but this can lead to misleading claims about the content of recycled materials. End users may believe that a product is entirely recycled, while only a fraction of it actually is. While this method is practical, it requires transparent and rigorous management to avoid distortions and ensure clear information for consumers.

What are the developments in recycled product regulations?

Regulations regarding the use of recycled materials are constantly evolving. It is therefore necessary to stay up-to-date with the applicable standards and legal requirements. Physico-chemical analyses help businesses comply with current regulations and adapt to future changes.

  • Circular Economy: The AGEC Law and Its Impact on Textiles

The AGEC (Anti-Waste for a Circular Economy) law imposes new obligations on the textile industry to reduce waste and encourage recycling. It mandates the prohibition of destroying unsold goods, the requirement for transparency on product composition, and strengthens manufacturers' responsibility for the end-of-life of textiles. These measures aim to transform the sector towards more sustainable practices, promoting the use of recycled materials and better resource management throughout the product life cycle.
