Sinopec's Innovative Biodegradable Material Revolutionizes Cotton Farming in Xinjiang

Sinopec, formally known as China Petroleum and Chemical Corporation, has made a groundbreaking advancement in agricultural technology with the successful implementation of its fully biodegradable PBST (polybutylene succinate-co-tereftalate) material. This innovative solution directly addresses the significant issue of plastic waste generated by traditional polyethylene (PE) mulch films used in cotton farming in Xinjiang, a major cotton-producing region in China.

The Problem of Plastic Waste in Cotton Farming

Xinjiang has long relied on PE mulch films to retain soil moisture and enhance temperature for cotton crops. However, these plastic films pose severe environmental challenges as they are difficult to degrade naturally. The accumulation of plastic waste not only contaminates the environment but also disrupts local ecosystems. The need for a sustainable alternative has never been more pressing.

PBST: The Game Changer for Sustainable Agriculture

Sinopec's PBST material was developed with independent intellectual property rights and has shown promising results in pilot programs conducted in the Wusu region of Xinjiang. The material has demonstrated nearly equivalent cotton yields compared to traditional PE films, while also meeting the required degradation speed and moisture retention capabilities outlined in its design goals.

What sets PBST apart from other biodegradable options, like PBAT, is its outstanding performance. Unlike PBAT, which has a shorter weather resistance cycle and tends to degrade prematurely, PBST maintains its integrity throughout the cotton-growing process. Long-term experiments have confirmed that PBST films can fully decompose into harmless water, carbon dioxide, and minerals within one to three years, significantly reducing the environmental footprint of cotton farming.

Large-Scale Implementation and Results

In a recent initiative, Sinopec launched the world’s first industrial-scale PBST production facility in Hainan. This facility is expected to produce 60,000 tons of PBST annually. Following this, in March, the company collaborated with local agricultural authorities and entities such as the Liaoning Dongsheng Group to implement a large-scale pilot project, covering over 10,000 mu (approximately 1,650 acres) of cotton fields in Wusu and Kuitun.

By October, third-party evaluations of the crops revealed that fields using PBST mulch achieved cotton yields comparable to those utilizing traditional PE films, with a notably advanced degradation rate. This remarkable performance validates the potential of PBST as a sustainable alternative in agricultural practices.

Economic and Environmental Benefits

The adoption of PBST not only addresses the agricultural demands of Xinjiang's cotton growers but also reduces costs associated with waste management. By minimizing solid waste from discarded PE films, Sinopec's innovative solution offers tangible economic and ecological benefits, paving the way for a sustainable future in agriculture.

Being environmentally conscious is fundamental in today's world, and Sinopec’s advancement with PBST provides a blueprint for other industries facing similar challenges with plastic waste. It demonstrates how innovation can lead to practices that are both economically viable and environmentally friendly, thus contributing to the global goal of sustainable development.
