群马大学一个研究小组公布的成果显示:他们开发出利用农业废弃物玉米芯高效制作工业生产常用的聚酯(PET)树脂技术,这一技术无需使用粮食作物,也有望为缓解全球气候变暖做出贡献。PET可用于制作薄膜片材、包装瓶、电子电器、汽车配件等。通常的PET以对苯二甲酸(PTA)为主要原料,而PTA则是从石脑油中提炼出来的。玉米脱粒后,剩下的玉米芯通常被视为农业废弃 The results released by a research group at Gunma University show that they have developed the efficient production of polyester resins commonly used in industrial production using agricultural waste corn cob without the need for food crops and are also expected to alleviate the global warming make a contribution. PET can be used to make film sheets, packaging bottles, electronic appliances, auto parts and so on. The usual PET is terephthalic acid (PTA) as the main raw material, while PTA is extracted from the naphtha. After the corn is threshed, the remaining corncobs are usually considered agricultural waste
