  Under the global environmental protection wave, post-consumer recycled plastics (PCR) are becoming the core competitiveness of China's manufacturing. The "Technical Specifications for the Use of Recycled Plastics in Household Appliances" (T/CHEAA 0034-2024), which will take effect in January 2025, requires that the proportion of PCR added to household appliances be up to 20%. This policy forces the industrial chain to upgrade. A modification factory in South China uses molecular-level purification technology and three-layer melt filtration to remove micron-level metal impurities in PCR, so that the transmittance of recycled polypropylene is increased to 92%, and the impact strength reaches 98% of the original material. Relying on the AI ​​visual sorting system, packaging companies in East China have increased the purity of PET bottle recycling to 99.2%, reducing raw material costs by 30%.      The key to technological breakthroughs lies in breaking the performance bottleneck of recycled materials. The nano-calcium carbonate reinforcement system developed by a leading enterprise has enabled the flexural strength of PCR-ABS materials to exceed 65MPa, successfully replacing imported materials for high-end air conditioner shells8. What is more noteworthy is that GRS global recycling standard certification is becoming a market pass - companies that pass this certification need to build a full-link traceability system, match each batch of goods with a TC transaction certificate, and provide 12 types of certification documents such as raw material procurement, transportation, and recycler qualifications. A daily necessities factory in Ningbo has increased its export orders by 40% with its GRS-certified food-grade PCR-PET lunch boxes.     The industry reshuffle has quietly taken place. A Dongguan injection molding factory suffered a loss of 3 million yuan due to the use of uncertified PCR materials, resulting in a product brittle cracking rate of over 15%; and Veolia Huafei, through the high-performance technology of marine plastics (OBP), jointly with the Chinese Academy of Sciences team, used molecular chain repair to increase the impact strength of recycled PET by 3 times, and combined with UL 2809 environmental certification to open up the high-end market4. With the GB/T 16288 standard requiring the labeling of recycled content on products, the green transformation of China's plastics industry is shifting from passive compliance to technology dividend-driven.

  The EU's "Packaging and Packaging Waste Regulation" (PPWR) sets a strict threshold: from 2030, the content of post-consumer recycled materials (PCR) in plastic packaging must reach 30%, and those who fail to meet the standard will be subject to a plastic tax of 800 euros per ton. This policy makes GRS Global Recycling Standard Certification a key breakthrough for Chinese companies - a plastic bag factory in Dongguan has relied on this certification to enter the supply chain of fast fashion giants with its 100% PCR composite packaging bags, with annual exports exceeding 180 million yuan.   The core value of GRS certification lies in building a reliable traceability system. Taking recycled plastic bags exported to the EU as an example, companies need to match TC transaction certificates for each batch of goods and provide 12 types of certification documents such as raw material procurement contracts, transportation documents, and recycler qualifications. A packaging company in Xiamen uses blockchain technology to shorten the traceability cycle from 7 days to 2 hours, greatly improving customer trust. The more far-reaching impact is in profit reconstruction. A daily necessities factory in Ningbo transforms PIR injection molding scraps into food-grade tableware, and the product premium reaches 25% after passing GRS certification; a material company in Shandong enters the UK infrastructure market with UKCA-certified PIR insulation boards, and its profit margin increases by 18%.   Technological innovation and certification are forming a synergistic effect. The high-performance technology of marine plastic (OBP) developed by the Chinese Academy of Sciences team increases the impact strength of recycled PET by 3 times through molecular chain repair, and opens up the high-end market with UL 2809 environmental certification. When TC certificates become the hard currency of green trade, China's plastics industry is moving from the OEM model to a new battlefield for standard setters.

  The "Technical Specifications for the Use of Recycled Plastics in Household Appliances" (T/CHEAA 0034-2024), which came into effect in January 2025, put post-consumer recycled plastics (PCR) in the spotlight - home appliance companies must achieve a mandatory quota of up to 20% of recycled materials. This policy is forcing the industrial chain to upgrade: Haier's molecular purification technology removes micron-level impurities in PCR through three-layer melt filtration, and its modified PCR polypropylene is used in the inner barrel of the washing machine, with an impact strength of 98% of the original material standard, reducing carbon emissions by 1.8 tons per ton.   The key to technological breakthroughs lies in solving the bottleneck of recycled material performance. A modified factory in East China uses a nano-calcium carbonate reinforcement system to make the flexural strength of PCR-ABS material exceed 65MPa, successfully replacing imported materials for air conditioner shells; packaging companies in South China use AI visual sorting systems to increase the purity of PET bottle recycling to 99.2%, reducing raw material costs by 30%.   The market reshuffle has already begun. A Dongguan injection molding factory used uncertified PCR materials, which resulted in excessive brittle cracking of products and caused losses of more than 3 million yuan; while companies that have passed GRS certification are rapidly gaining market share - Ningbo Lishi's food-grade PCR-PET lunch boxes can provide complete TC transaction certificates, and export orders will increase by 40% in 2024.   With the GB/T 16288 standard requiring the labeling of recycled content on products, a policy-driven green transformation is shifting from compliance costs to technological dividends. When air conditioner shells carry 30% of post-consumer plastic components, the sustainable transformation of China's manufacturing has penetrated into the supply chain.

  In early 2025, Haier Recycling and Toyota Tsusho reached a strategic cooperation to jointly develop automotive-grade PCR recycled plastics with a purity of up to 99.9%, directly addressing the pain points of core components of new energy vehicles. Traditional recycled plastics have long been difficult to meet automotive safety standards due to their high impurities and unstable performance. Haier relies on the "five-network integration" recycling network covering the whole country and the Qingdao interconnected factory to achieve 100% removal of metal impurities through cutting-edge sorting and cleaning technology, with an impurity rate of less than 0.2%, and almost zero attenuation of recycled material properties. This breakthrough enables PCR materials to replace virgin plastics for key components such as bumpers and interiors, reducing carbon emissions by 21% for a single vehicle.   The core competitiveness of this cooperation lies in the closed-loop traceability system: Toyota Tsusho provides global chemical compliance support to ensure that materials comply with the laws and regulations of various countries; Haier controls the entire process of home appliance recycling-disassembly-regeneration to ensure a large-scale and stable supply of raw materials. Its annual PCR production capacity of 30,000 tons is accelerating the replacement of imported products such as Covestro. Wanhua Chemical, Life Recycling and other companies are also simultaneously deploying modified PCR-PC/ABS alloys to enter the automotive-grade structural parts market. The EU ELV regulations require that the proportion of recycled materials in new car plastics by 2031 should be no less than 25%. Shanghai Aossel invested 300 million yuan to build a 200,000-ton PCR zero-carbon plant. Through intelligent sorting and carbon footprint systems, it provides localized solutions for the implementation of regulations and promotes the green transformation of the automotive supply chain in China, Japan and South Korea.
