Waste, rubbish, trash, garbage, or junk is unwanted or undesired material.
There are a number of different types of waste. It can exist as a 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. The term waste implies things which have been 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. The biodegradable component of wastes (e.g. paper & food waste) can be composted or anaerobicly digested to produce soil improvers and renewable fuels. If it is not dealt with sustainably in this manner biodegradable waste can contribute to greenhouse gas emissions and by implication climate change [1].
There are two main definitions of waste. One view comes from the individual or organisation producing the material, the second is the view of Government, and is set out in different acts of waste legislation. The two have to combine to ensure the safe and legal disposal of the waste [2].

"Waste" is anything that is not of use and generally harmful to anyone or any living thing.
Hence, manure is not a waste as it can be used a fertiliser after treatment.
