VaryTech's Innovative System for Waste Plastic Recycling

Recently, Zhou Zhiqiang, former Deputy Director-General of the Solid Waste and Chemicals Department of the Ministry of Ecology and Environment, First-Level Inspector, and President of the Recycled Plastics Branch of the China National Resources Recycling Association, along with Secretary-General Wang Yonggang, visited Vary Tech’s headquarters and its Miluo base for an investigation. Ming Guoying, Chairman of Hunan Vary Tech Co., Ltd., accompanied the delegation.

Zhou Zhiqiang and his team conducted on-site inspections of core sectors including waste plastic recycling, end-of-life appliance dismantling, high-value utilization of appliance waste plastics, and pyrolysis of waste plastics. They highly praised Vary Tech’s groundbreaking achievements in addressing challenges related to plastic recycling.





As a pioneer in the resource utilization of solid waste, Vary Tech has driven innovation through technological advancements for over 20 years. Starting with appliance dismantling in 2009, the company has progressively built a comprehensive technical system covering waste plastic front-end collection, mid-end sorting, and back-end physical recycling, chemical recycling, and AI-enabled digital management.

In terms of physical recycling, Vary Tech’s seventh-generation end-of-life appliance dismantling line can process 200 refrigerators per hour, with a waste plastic sorting rate exceeding 97%. Through automated deep-processing equipment, these sorted appliance waste plastics are ultimately converted into high-quality post-consumer recycled (PCR) plastic products, which are then used in manufacturing sectors such as home appliances and automotive industries. However, physical recycling is not a universal solution. For mixed plastics that are difficult to recycle physically, the company’s self-developed oxygen-free pyrolysis technology provides an effective answer. This technology has already achieved large-scale application, with a single unit capable of processing 150 tons per day, yielding three types of resource-recoverable products: pyrolysis oil, pyrolysis gas, and pyrolysis carbon. Among these, pyrolysis oil can be refined into gasoline/diesel or further processed into olefin chemicals; pyrolysis gas is reused in the pyrolysis system or converted into raw materials for green hydrogen; and pyrolysis carbon is utilized in construction materials or carbon black production. This technological breakthrough has fully unlocked the pathway for transforming low-value plastics into high-value products.



In 2024, Vary Tech launched an AI-powered digital traceability management cloud system, aiming to achieve real-time monitoring and traceability management throughout the entire lifecycle of waste plastics—from collection to recycled products. This initiative provides new digital empowerment for enhancing industry transparency.

At the Changsha County Green Resource Sorting Center, Vary Tech has established a refined recycling and sorting system covering six major categories and 58 subcategories of plastics, including PET, PP, PE, low-value waste plastics, and waste rubber. Through standardized classification, packaging, and directional transportation, various types of waste plastics are ultimately transformed via deep processing. Leveraging its subsidiaries—Hunan Vary Solid Waste, Miluo Vary E-Waste, and Vary Rili—the company has formed a closed-loop system encompassing “front-end collection, mid-end sorting, and back-end resource recovery and regeneration.” This system covers high-value utilization of appliance waste plastics and chemical recycling of mixed plastics from domestic, industrial, and medical sources.

In response to the stringent requirements of the EU’s Packaging and Packaging Waste Regulation (PPWR)—mandating 30% recycled content in plastic packaging by 2030 and 65% by 2040—Vary Tech has adopted a dual strategy: ensuring stable supply of high-quality PCR through physical recycling while utilizing chemical recycling to process mixed waste that cannot be physically recycled. This approach has solidified the company’s robust technological capabilities.

This investigation highlights the core trends in the recycled plastics industry: physical recycling must pursue efficiency through refinement and automation; chemical recycling will become a key pathway for large-scale disposal of low-value plastics; and digital-intelligent management serves as the cornerstone for ensuring supply chain credibility. Vary Tech’s practices demonstrate that through integrated full-chain technologies and innovative business models, China’s recycled plastics industry is rapidly transitioning from “low-end recycling” to “high-tech value addition.”

Looking ahead, the development of a circular economy for plastics requires comprehensive innovation across the entire “reduce-reuse-recycle” chain, where technological advancements and model upgrades are indispensable. Vary Tech’s exploration not only charts a course for the industry but also provides innovative solutions to address global plastic pollution challenges.
