中国石化破解新疆棉田地膜残留难题

Core Viewpoint - Sinopec has successfully tested its fully biodegradable PBST film in cotton fields, providing a viable solution to stabilize cotton yields and address the issue of plastic film residue in agriculture [1][2] Group 1: Product Development - The PBST film, developed by Sinopec's Beijing Chemical Research Institute, has complete independent intellectual property rights and shows superior performance in UV resistance and moisture barrier compared to other biodegradable materials [1] - The film can fully degrade into harmless substances such as water, carbon dioxide, and minerals within 1 to 3 years, making it environmentally friendly [1] Group 2: Agricultural Impact - In October, third-party assessments indicated that cotton fields using PBST film had comparable yields to those using traditional PE film, while also demonstrating a significantly faster degradation rate [2] - The use of PBST film not only meets the growth requirements of cotton in Xinjiang but also reduces costs and effectively addresses the soil contamination issues caused by PE film residues, thus promoting sustainable agricultural development in the region [2]
