Waste is unwanted and discarded materials and objects. It is often also called trash, garbage, rubbish, or junk. There are a number of different types of waste. It can exist as a solid, liquid, or gas or as waste heat. Garbage is the waste produced daily in our homes. It includes different waste like food, chemical substances, paper, broken furniture, used containers, and other things.

When released in as a liquid or gas the wastes can be referred to as emissions. It is usually strongly linked with pollution.

Waste may also be something that you cannot touch as wasted time or wasted opportunities. The term waste in this sense implies things which have been used inefficiently or inappropriately.

Waste management[change | edit source]

In modern homes and businesses, garbage is normally placed in waste containers of some sort. It is then moved to the street, where it can be collected and taken to a place designed to hold, destroy or recycle garbage. Some waste materials, such as paper, wood, glass, metals, and plastic containers, can be recycled (reused). Materials that can not be recycled are either burned (incinerated) or heaped into landfills.

Plant matter, such as fruit and vegetable scraps, is biodegradable. It can usually be heaped into a compost, where it will decompose relatively quickly. This kind of waste is often called "wet" or "green" waste.

Very often, waste is not collected in containers. It may instead be thrown onto the ground or dumped somewhere. This is called littering.
