  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.

  In February 2025, Polyplastics announced the launch of the world's first 40% glass fiber reinforced PIR recycled PPS - DURAFIDE® rG-PPS, reconstructing the recycling logic of super engineering plastics through the "Open PIR Program"25.   The technical breakthrough lies in the "re-blending" process:   Source control: only self-produced glass fiber reinforced PPS scraps are recycled to eliminate raw material performance fluctuations;   Deep metal removal: 100% removal of metal impurities in the previous process to ensure electrical insulation;   New material compounding and strengthening: recycled materials and virgin materials are scientifically blended and passed the quality test equivalent to new materials5.   This technology reduces the product carbon footprint (PCF) by more than 30%, and will be first supplied to the Japanese market after mass production in December 2025. Polyplastics simultaneously develops high-filled grades and plans a global "local production-local consumption" recycling chain to meet the mandatory requirement of 25% recycled plastics in the EU ELV regulations5.   Differentiated value of PIR and PCR:   Source difference: PIR is derived from factory production waste (such as nozzles, defective products), and its quality stability is better than PCR plastics recycled after consumption;   Application scenarios: PIR recycled PPS is suitable for high-reliability fields, such as new energy vehicle battery brackets and 5G base station precision components, while PCR focuses more on daily necessities and packaging8.   China's inspiration: Cangzhou Dahua's continuous production of silicon copolymer PC and Wanhua Chemical's PCR modification technology show that domestic companies are learning from the PIR model to tackle high-end recycled engineering plastics and promote 100% recycling of PA, PC, etc.

I. Global Policies Drive Market Change   The plastic circular economy is ushering in an unprecedented policy dividend period. Starting in 2023, many countries and regions around the world will begin to implement mandatory recycled plastic content requirements, pushing the PCR plastic market from a "moral option" to a "compliance requirement". The UK's plastic packaging tax, which will be implemented from April 2024, stipulates that plastic packaging that uses less than 30% recycled materials will be subject to a tax of £200 per ton1. The EU's Packaging and Packaging Waste Regulation (PPWR) requires that all plastic packaging contain at least 50% recycled materials by 2030. In the field of electronics and electrical appliances, China's "Specifications for the Use of Recycled Plastics in Electrical and Electronic Products" was issued in 2023, clearly stipulating the target addition ratio of recycled plastics in products such as washing machines and air conditioners6. This policy will directly stimulate the growth in demand for PCR engineering plastics, especially high-end materials such as PC and PC/ABS. Driven by the policy, the PCR plastic market has shown explosive growth. According to Grand View Research, the global PCR plastic market will reach $89.5 billion in 2030, with a compound annual growth rate of 11.2%. Among them, the electronics and automotive industries will become the fastest growing application areas, accounting for more than 40% of the market share. 2. Technological innovation breaks through performance bottlenecks   Upgrade of sorting and cleaning technology Efficient sorting is the basis for obtaining high-quality PCR raw materials. The new generation of sorting technology has achieved molecular-level identification: AI visual sorting system: Identify plastic type and color through machine learning, with a sorting accuracy of >99% Laser induced breakdown spectroscopy (LIBS): Accurately identify additives such as bromine-containing flame retardants Hydrophobic flotation: Separate PE/PP mixtures using surface tension differences For severely polluted post-consumer recycled materials, the ZSK FilCo compounding extrusion system developed by Coperion achieves one-step filtration and modification. The system first melts and homogenizes the waste plastic, then removes contaminants through an integrated filter, and finally re-feeds it into the modification zone to add reinforcement materials2. Compared with the traditional two-step method, this technology reduces energy consumption by 50%, while avoiding polymer degradation caused by secondary melting. High-performance modification technology Nano-enhancement technology has made a major breakthrough in the field of PCR plastics. Studies have shown that adding 0.8-1.5 parts by weight of nano-zirconia and 2-3 parts by weight of polarized particles can increase the whiteness of PCR PC to 98.6% and the transmittance to 91.2%8. This breakthrough has enabled PCR materials to be successfully applied to fields with strict requirements on optical performance, such as backlit keyboards of high-end notebooks. Chemical recycling technology has also made progress. The chemical depolymerization process developed by Covestro can depolymerize waste PC products into monomers, and the performance of the recycled materials is exactly the same as that of the original materials. This technology has been commercialized with an annual processing capacity of 25,000 tons. Innovative alloy development Weather-resistant enhanced PCR PC/ABS: Adding hollow silica microspheres (0.3-0.8μm, hollow ratio>90%) to improve weather resistance High-flow PCR PET/PC: Controlling ester exchange through reactive compatibilizers, the melt index is increased by 35% Flame-retardant halogen-free alloy: Suzhou Waldorf SustainX® series achieves 1.5mm V-0 flame retardant grade

  On April 21, Shanghai Osel Materials Technology Co., Ltd. and Tianjin Economic Development Zone officially signed a letter of intent for investment cooperation, and will invest in the construction of a PCR (Post-Consumer Recycled material, post-consumer recycled material) plastic intelligent fine sorting and high-end granulation digital zero-carbon factory project in the northern part of Nangang Industrial Zone. This project will create the largest "car-to-car" high-value closed-loop utilization system in China, help the development of the circular economy, and set an international benchmark. The total investment of the project is 300 million yuan, covering an area of ​​100 acres. After completion, it will produce 200,000 tons of PCR plastics annually. Among them, the first phase will invest 100 million yuan, cover an area of ​​30 acres, and plan to produce 50,000 tons of PCR plastics annually. The project will join forces with world-renowned industry chain partners to jointly promote the localized closed-loop recycling application of automotive plastics, help the automotive industry effectively respond to the challenges of "carbon tariffs" and "green trade barriers", and promote China's manufacturing to connect with international ESG standards.
