The composition about garbage classification is urgent, urgent and urgent.

Dear, I can't write a composition, but regarding garbage classification, I suggest you search the current garbage classification process in Japan. Japan is the top in the world in this respect.

My college graduation project is about garbage classification, mainly garbage incineration. I really can't write such a small composition as yours.

See, you mean that the trash can in the future can automatically sort garbage. This course is difficult. I remind you that when throwing beverage bottles in Japan, the cap, the bottle body and the film on the bottle body are all plastic, but they should be discarded separately. There are many kinds of garbage cans in Japan, but if you don't want to be in China, you can only recycle them, and they are all decorations.

After nagging for a long time, I'm going to bed . . . For reference only, if you want an article, I suggest you add words, and someone may answer.
