During the 38th China International Plastics Rubber Exhibition (Chinaplas 2026), Henan Pingyuan New Material Technology Co., Ltd., Chengfa Environment Recycling Technology (Henan) Co., Ltd., and Sulzer Ltd. of Switzerland officially signed a Tripartite Framework Cooperation Agreement on April 22, 2026, marking the official launch of the “world’s first thousand-ton pilot project for waste HDPE solvent-based recycling.”

The project actively responds to the Paris Agreement (UNFCCC) and China’s “carbon peaking and carbon neutrality” strategy, representing a high-level international collaboration in the field of plastic circular economy. The three parties will fully leverage their respective professional and resource advantages to accelerate the transition of waste HDPE solvent-based recycling technology from the laboratory to an industrial-scale thousand-ton pilot, filling a critical gap in the industry both domestically and globally.

Driven by global regulatory requirements, the high-end recycled plastics market faces strong demand for high-quality recycled HDPE, yet existing production processes struggle to consistently meet corresponding quality standards. This innovative project breaks away from the traditional mechanical recycling model of “downcycling and value loss,” as well as the high-cost challenges of chemical recycling, exploring a new technological pathway and business model combining “solvent-based processing + high-value recycling.” The project is expected to achieve a fundamental shift from “waste treatment” to “high-end resource reclamation,” effectively alleviating the bottleneck in the supply of premium recycled materials.

The pilot project aims to provide a stable supply of high-quality raw materials for downstream high-end applications such as food packaging, automotive, and electronic appliances. It will support the new dual-circulation development pattern both domestically and internationally, while contributing an important Chinese solution to achieving national “dual carbon” goals and combating global plastic pollution.

All parties agreed that the project has broad prospects and far-reaching significance, and is poised to become a landmark demonstration project and a global benchmark for the circular plastic economy.
