但是厨余垃圾在这里只是指比较容易分解的那些，比如豆渣。它不解决大多数中国公共食堂、餐厅里最难以处理的厨余垃圾，比如剩菜剩饭，它们算不算厨余垃圾？泔水怎么处理呢？短片中没看到特别有科技含量的（碳氮比是多少也没明说啊），和我以为的方式有点差距。
无论如何，大学生参与环保，身体力行，精神可嘉！

However, the waste here only refers to those that decompose relatively easily, such as soybean dregs. It doesn't solve the hard-to-deal-with food waste in the majority of canteens and restaurants in China, such as leftovers. Are leftovers considered to be food waste? How is it dealt with? There was no science and technology content in the short clip (the carbon and nitrogen ratio was not mentioned) and is different from the way that I thought. In any case, students who participate in and encourage environmental protection are commendable!
