阿联酋科学家将咖啡和塑料转化为碳捕获材料。 UAE scientists turn coffee grounds and plastic into carbon-capturing material.

阿联酋的研究人员发明了一种低成本、可持续的方法,从用过的咖啡场和PET塑料中生产活性碳,能够捕捉二氧化碳的排放。 Researchers in the UAE have created a low-cost, sustainable method to produce activated carbon from spent coffee grounds and PET plastic, capable of capturing CO₂ emissions. 该工艺于2025年3月获得专利,并于8月公布,使用氢氧化钾和600摄氏度活化温度将废物转化成高性能吸附剂。 The process, patented in March 2025 and published in August, uses potassium hydroxide and a 600°C activation temperature to transform waste into a high-performance adsorbent. 它解决两个主要污染源——800万吨咖啡废物和大面积塑料废物,把它们重新用作碳捕获、空气和水净化以及工业天然气处理的有用材料。 It addresses two major pollution sources—eight million tons of coffee waste and vast plastic waste—by repurposing them into a material useful for carbon capture, air and water purification, and industrial gas treatment. 该创新支持循环经济,减少垃圾填埋的使用,并为减少温室气体排放提供可扩展的潜力。 The innovation supports a circular economy, reduces landfill use, and offers scalable potential for mitigating greenhouse gas emissions.
