Oh!!! Waste
Waste (also known as rubbish, trash, refuse, garbage, or junk) is unwanted or unusable materials. Litter is waste which has been disposed of improperly, particularly waste which has been carelessly disposed of in plain sight, as opposed to waste which has been dumped to avoid paying for waste disposal fees.
In living organisms, waste is the unwanted substances or toxins that are expelled from them. More commonly, waste refers to the materials that are disposed of in a system of waste management.
Waste is directly linked to 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.
Waste is sometimes a subjective concept, because items that some people discard may have value to others. It is widely recognized that waste materials are a valuable resource, whilst there is debate as to how this value is best realized.
There are many waste types defined by modern systems of waste management, notably including:
- municipal solid waste (MSW)
- construction waste and demolition waste (C&D)
- institutional waste, commercial waste, and industrial waste (IC&I)
- medical waste (also known as clinical waste)
- hazardous waste, radioactive waste, and electronic waste
- biodegradable waste
