除了从废可乐瓶中提取原料之外,以“生物质”替代石油作为化纤工业原料是另外一个重要的方向。众所周知,石油资源不可再生而且储量有限,同时石油制品的消耗,还带来了严重的环境污染和温室效应,据国家统计局的数据显示,石油价格每上涨10%,化纤工业的原料就要上涨20%～80%。乙烯 In addition to extracting raw materials from waste cola bottles, the replacement of petroleum with “biomass” as a raw material for chemical fiber is another important direction.
