Recently, Chinese scientists have successfully developed an innovative ‘waste-to-value’ technology capable of efficiently converting common pollutants—such as agricultural residues and plastic waste—into high-value products like biofuels, biodegradable materials, and chemical feedstocks. The technology leverages advanced catalytic conversion and microbial fermentation processes, significantly improving resource recovery efficiency while reducing environmental pollution.Take crop straw as an example: traditionally disposed of through open burning or landfilling, it not only wastes valuable biomass but also pollutes air and soil. The new method uses specialized catalysts to break down cellulose and hemicellulose in straw into sugars under mild conditions, which are then fermented by microbes into ethanol or other organic chemicals. Similarly, for hard-to-degrade plastic waste, the research team has developed a novel enzyme-based catalytic system that can depolymerize plastics into reusable monomers within hours.This breakthrough was achieved through collaborative efforts by multiple institutes under the Chinese Academy of Sciences. The technology is now in the pilot-testing phase and has launched demonstration projects in several provinces. Experts believe it holds great promise for advancing the circular economy and achieving China’s carbon peaking and carbon neutrality goals, offering a ‘Chinese solution’ to global waste management challenges.
近日，中国科学家成功研发出一项“变废为宝”的创新技术，可将农业废弃物、塑料垃圾等常见污染物高效转化为高附加值产品，如生物燃料、可降解材料和化工原料。该技术基于先进的催化转化与微生物发酵工艺，不仅大幅提升了资源回收效率，还显著减少了环境污染。以秸秆为例，传统处理方式多为焚烧或填埋，不仅浪费资源，还会造成空气和土壤污染。而新技术通过特定催化剂，在温和条件下将秸秆中的纤维素和半纤维素分解为糖类，再经微生物发酵生成乙醇或其他有机化学品。同样，针对难以降解的塑料垃圾，科研团队开发出一种新型酶催化体系，可在数小时内将其分解为可再利用的单体原料。这项成果由中国科学院多个研究所联合攻关完成，目前已进入中试阶段，并在部分省份开展示范应用。专家表示，该技术有望在推动循环经济、实现“双碳”目标方面发挥重要作用，为全球废弃物治理提供“中国方案”。
