什么是垃圾
Waste, rubbish, trash, or garbage is unwanted or undesired material.

Waste falls into a number of different waste types. It can exist in any phase of matter (solid, liquid, or gas) or as waste heat. When released in the latter two states the wastes can be referred to as emissions. It is usually strongly linked with pollution. Waste may also be intangible in the case of wasted time or wasted opportunities. Here waste refers to things which are used inefficiently or inappropriately.

Some components of waste can be recycled once recovered from the waste stream, e.g. plastic bottles, metals, glass or paper.

Biodegradable waste or, if recovered, the biodegradable component of mixed wastes (e.g. paper & food waste) can be composted or anaerobicly digested to produce soil improvers and renewable fuels.
