Garbage Classification is to classify garbage as domestic waste according to the classification methods of "recyclable and reusable" and "non-recyclable and reusable". The daily life of human beings will produce a large amount of domestic waste, and a large amount of waste will be polluted if it is reused without being sorted and discarded.

In the present book, fifteen typical literatures about Garbage Classification published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on garbage classification, "recyclable" garbage and "non-recyclable" garbage etc. We hope this book can demonstrate garbage classification as well as give references to the researchers, students and other related people.
