巴斯大学可持续化学技术中心(CSCT)的科学家研究发现,可以使用糖和二氧化碳制作可生物降解的塑料,进而替代以原油为基础原料制作的塑料。聚碳酸酯可用于制造饮料瓶、眼镜镜片等,目前聚碳酸酯的制造工艺使用双酚A(BPA)和高毒性光气(在第一次世界大战中被用作化学武器)。巴斯的科学家们采用一种新工艺,在低压和室温下向糖中添加二氧化碳,从而制成一种聚碳酸酯替代塑料。该塑料具有与石 Scientists at the University of Bath’s Center for Sustainable Chemistry Technology (CSCT) have found that biodegradable plastics can be made from sugar and carbon dioxide to replace plastic made from crude-based raw materials. Polycarbonate can be used to make beverage bottles, eyeglass lenses, etc. Currently polycarbonate is manufactured using BPA and highly toxic phosgene (used as a chemical weapon in World War I). Bath’s scientists used a new process to add carbon dioxide to sugar at low pressure and room temperature to make a polycarbonate-based alternative to plastic. The plastic has with stone
