What Is Waste?

This is a short article for my project which I downloaded from internet.

Waste is an unwanted or undesired material or substance. It is also referred to as rubbish, trash, garbage, or junk depending upon the type of material and the regional terminology. In living organisms, waste relates to unwanted substances or toxins that are expelled from them.Waste management is the control of the collection, treatment and disposal of different wastes. This is in order to reduce the negative impacts waste has on environment and society. There are many waste types, notably including municipal solid waste, commercial waste, and hazardous waste.

Waste is directly linked to the human development, both technologically and socially. The composition of different wastes have varied over time and location, with industrial development and innovation being directly linked to waste materials. Examples of this include plastics and nuclear technology. Some components of waste have economical value and can be recycled once correctly recovered.
