Zhangjiagang’s “advanced dissolution technology” breaks new ground! PC recycling production line set up along the strategic Yangtze River waterway 2025-04-22 17:08 · Chlor-Alkali Frontline On April 20, China’s circular economy may reach a milestone: Shengxi Ao’s world’s first polycarbonate (PC) dissolution recycling project was officially launched in Zhangjiagang. This multi-million-yuan \"cutting-edge technology\" production line is capable of turning scrap auto parts and mixed plastics from electronic waste into something valuable, by extracting high-purity recycled PC with properties comparable to those of virgin materials. This means that the 2 million tons per year of electronic waste, which in the past could only be landfilled or incinerated, is now set to become a valuable raw material for high-end manufacturing. Solving 20 years of industry pain points: Direct feeding of phone cases with paint. This project will utilize Shengxiao’s proprietary dissolution technology to extract PC polymers from discarded automotive parts, consumer electronics, and other sources through selective solvents, thereby enabling efficient recycling and reuse of these materials. Compared to traditional mechanical recycling methods, dissolution technology can handle mixed or contaminated materials, expanding the range of PC waste that can be recycled and providing a broader set of solutions for a circular economy. New technology increases processing efficiency by 5 times and reduces raw material waste by 70%. The project leader revealed that the first production line has an annual processing capacity of 20,000 tons, sufficient to meet 60% of the demand for electronic waste plastic recycling in the Yangtze River Delta region. “\"Mutual pursuit\": The dynamics behind the lightning-fast approval in 45 days. It is reported that the Zhangjiagang government set a record for the speed of approving this project: it took only 45 days from the publication of the environmental impact assessment to the issuance of the construction permit. This is thanks to the \"special plots for a circular economy\" designated in the local chemical industrial park, as well as the policy of immediate refund of value-added tax for enterprises dealing in recycled materials. More importantly, the facility is located adjacent to the Yangtze River’s vital waterway, allowing the processed recycled PC to be delivered by water directly to automobile and electronics companies downstream, thereby reducing logistics costs by 40% compared to land transport. As global attention to a circular economy and sustainable development continues to grow, Shengxiao’s PC recycling project will set a new benchmark for the industry. Through close collaboration with the local government, Shengxi Ao aims to establish a circular economy demonstration project in Zhangjiagang, fostering innovation and the application of plastic recycling technologies to contribute to global sustainable development goals.
