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.
A big part of waste management deals with municipal solid waste, which is created by industrial, commercial, and household activity. [4] Waste management practices are not the same across countries (developed and developing nations); regions (urban and rural areas), and residential and industrial sectors can all take different approaches.

Cleaner production is a preventive, company-specific environmental protection initiative. It is intended to minimize waste and emissions and maximize product output. [1] By analysing the flow of materials and energy in a company, one tries to identify options to minimize waste and emissions out of industrial processes through source reduction strategies.
Here represents the square matrix of input coefficients, denotes releases (such as emissions or waste) per unit of output or the intervention matrix, stands for the vector of final demand (or functional unit), is the identity matrix, and represents the resulting releases (For further details, refer to the input-output model).
Resource recovery can be enabled by changes in government policy and regulation, circular economy infrastructure such as improved 'binfrastructure' to promote source separation and waste collection, reuse and recycling, [5] innovative circular business models, [6] and valuing materials and products in terms of their economic but also their social and environmental costs and benefits.

Waste Management has said that the plant, announced in April 2008, and built and operated by The Linde Group with state funding, is the world's largest facility to convert landfill gas into vehicle fuel. [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.
Waste valorization, beneficial reuse, beneficial use, value recovery or waste reclamation [1] is the process of waste products or residues from an economic process being valorized (given economic value), by reuse or recycling in order to create economically useful materials.
Landfills waste are categorized by either being hazardous, non-hazardous or inert waste. In order for a landfill design to be considered it must abide by the following requirements: final landforms profile, site capacity, settlement, waste density, materials requirements and drainage.
