The term “waste” refers to any material or object that is no longer useful or needed by its holder and is therefore disposed of. This can include substances, such as chemicals or hazardous waste, as well as objects like appliances, electronics, or packaging materials. Waste can be generated by households, businesses, and industries, and can have a range of negative environmental impacts if not properly managed.

Waste can be classified into different categories based on its composition, such as organic waste, recyclable waste, and hazardous waste. It can also be characterized by its source, such as municipal waste, industrial waste, or medical waste. The management of waste involves collection, transportation, treatment, and disposal, and it is important to adopt sustainable waste management practices to minimize environmental harm and promote resource conservation.

Efforts to reduce waste generation and promote recycling and reuse have become increasingly important as the world faces pressing environmental challenges, such as climate change and depletion of natural resources. Effective waste management is essential to protect human health and the environment, and to ensure a sustainable future for generations to come.
