Industrial waste may pollute the nearby soil or adjacent water bodies, and can contaminate groundwater, lakes, streams, rivers or coastal waters. [1] Industrial waste is often mixed into municipal waste, making accurate assessments difficult. An estimate for the US goes as high as 7.6 billion tons of industrial waste produced annually, as of 2017.

The concept of a circular economy can be linked to various schools of thought, including industrial ecology, biomimicry, and cradle-to-cradle design principles. Industrial ecology is the study of material and energy flows through industrial systems, which forms the basis of the circular economy.

[40] [41] [42] Waste Management works with environmental groups in the U.S. to set aside land to create and manage wetlands and wildlife habitats.
Industrial ecology (IE) is the study of material and energy flows through industrial systems. The global industrial economy can be modelled as a network of industrial processes that extract resources from the Earth and transform those resources into by-products , products and services which can be bought and sold to meet the needs of humanity.
Waste management industry, or waste industry for short, subsumes all industrial branches concerned with waste management, waste dumping, waste recycling and - to a lesser degree - waste prevention. Within Germany, waste management has evolved into a large economic sector. There are more than 270,000 people working in some 11,000 companies with ...
