Recycled plastic Certifications
Environmental conservation has become a focal point of global concern since the global warming and ocean pollution has continued to worsen. Whether it's national governments or private enterprises, there is an increasing emphasis on environmental-friendly materials, low-carbon processes, and eco-friendly products. This has prompted various parties to gradually establish standards and regulations for the use of recycled materials, leading to the emergence of carbon taxes, carbon emission fees, recycled material certifications, and eco-labels related to environmental conservation.   When companies commit to reducing their carbon footprint and obtain relevant recycled material certifications or environmental labels, they are better positioned to gain recognition and trust from both customers and end users in the realm of green environmental practices. Recycled plastics are primarily divided into two categories: Post-Industrial Recycled material (PIR) and Post-Consumer Recycled material (PCR). PIR materials are sourced mainly from industrial tailing and offcuts, while PCR materials originate from household waste generated in daily life. PIR, being recycled plastic from pre-consumer sources, tends to offer relatively higher quality and stability, whereas PCR benefits from its higher volume and consistent availability due to its source in everyday household waste.
Recycled plastic・Certification Type
The trends of “net zero”, “zero carbon” and “plastic reduction “have led various countries to introduce regulations such as carbon taxes, carbon emission fees, and plastic taxes. This has prompted major manufacturers of relevant products to begin using a certain percentage of certified plastic recycled materials in response to these trends, with the aim of reducing their carbon emissions. Common certifications for recycled plastics include Blue Angle, Global Recycled Standard (GRS), Recycled Claim Standard (RCS), and UL2809 Recycled Content Verification. Depending on the intended use, types of end products, and target markets, the required or accepted certifications for recycled plastics may vary. The application process and testing procedures for each recycled plastic certification also differ accordingly. Below is a brief introduction to several of the most common and widely applicable international certifications for plastic recycled materials.
Blue Angle
The Blue Angel label is the world's first and one of the most internationally recognized eco-labels. To obtain this label, the final product must contain at least 80% recycled materials. The Blue Angel label is a German eco-label, and it is owned by the German Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety, making it highly regarded in Europe.
GRS-Global Recycled Standard)
The Global Recycle Standard (GRS) is owned by the Textile Exchange and is one of the most prominent certifications in the textile industry. GRS establishes guidelines for recycling content, production processes, chemical use restrictions, and social responsibility practices, ensuring product traceability and environmental friendliness. The scope of verification is not limited to textiles, but for a product to be GRS-certified, it must consist of at least 20% recycled materials in its raw materials, with clear indication of the proportions of Post-Industrial Recycled material (PIR) and Post-Consumer Recycled material (PCR). To be eligible for the GRS verification label (hangtag), a product's raw materials must contain at least 50% recycled content. Upon obtaining GRS verification, in addition to receiving a certificate, a Transaction Certificate (TC) can be issued at the customer's request during shipment. The TC is issued by the verification body and certifies that the product's content, weight, composition, and other details comply with GRS standards. Additional fees apply for each TC.
RCS-Recycled Claim Standard)
The Recycled Claim Standard (RCS) is also introduced by the Textile Exchange with the aim of promoting the use of recycled materials. It is applicable to any product containing at least 5% recycled materials. RCS labels come in two categories: "RECYCLED BLENDED" for products with a recycled material content ranging from 5% to 95%, and "RECYCLED 100" for products with a recycled material content exceeding 95%. RCS does not encompass processing and manufacturing, quality, regulatory, social, or environmental issues; it solely focuses on the recycled material component. As a result, it's often referred to as a simplified version of GRS. Similar to GRS, TC Transaction Certificates can also be issued upon customer request at the time of shipment.
UL2809
The Recycled Content Verification UL2809 is introduced by UL, a globally recognized third-party certification and standards development organization. Its purpose is to assist manufacturers in declaring the content of recycled materials in their products. It applies to four types of recycled materials: Post-Industrial Recycled material (PIR), Post-Consumer Recycled material (PCR), Closed Loop Recycled, and Ocean Plastic / Ocean Bound Plastic.  Unlike the three certifications mentioned above, the UL2809 verification process primarily focuses on the review of written documents related to the manufacturing process, supplier statements, and production
GRS System - Overview of Operations
The GRS system covers the verification of recycled materials' inputs, supply chain, social and environmental practices, and chemical control. Applicants can be manufacturers of recycled products (including semi-finished and finished products), traders or brand and preparing to join the GRS verification system. If a company outsources all or part of the production of finished products, the relevant production units must also comply with GRS standards.  When companies apply for GRS for their products and pass it, they will receive a Scope Certificate (SC) for the verified products. This Scope Certificate (SC) only confirms that the company has passed GRS verification and does not prove whether any goods or materials comply with specific standards. This aspect must be proven through Transaction Certificates (TC). Transaction Certificates (TC) will detail the shipment's specific information, including the content, weight of recycled materials, information about the shipping and receiving companies, proof of incoming and outgoing quantities (numbers), and other relevant information.
【Example】

  • Recycling Plant:PET Recycling & Pelletizing Manufacturer
  • Production Plant: Textile Factory
  • Brand: H&M

  • The PET Recycling & Pelletizing Manufacturer must first apply for GRS certification for their PET pellets. After passing the certification, they obtain a Scope Certificate (SC) for their product and provide a Transaction Certificate (TC) when shipping the goods to the textile factory. The textile factory and H&M also need to follow the same steps to apply for GRS certification for their products.
