请问一下这个题的中文意思
我有点看的糊涂啦
谢谢啦~~~
51. One variety of partially biodegradable plastic beverage container is manufactured from small bits of plastic bound together by a degradable bonding agent such as cornstarch. Since only the bonding agent degrades,leaving the small bits of plastic, no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded.
谢谢喽~

一种可部分降解的塑料饮料罐由一些小块塑料与可降解的粘合剂（如，淀粉）制造出。因为只有粘合剂降解，而小块塑料不可，所以当这种饮料罐被废弃时，每个饮料罐产生的塑料废物一点也不少于不和降解的饮料罐。
