Waste treatment
Template:Short description Waste treatment refers to the activities required to ensure that waste has the least practicable impact on the environment. In many countries various forms of waste treatment are required by law.
Solid waste treatment
Template:Main The treatment of solid wastes is a key component of waste management. Different forms of solid waste treatment are graded in the waste hierarchy.
Waste water treatment
Agricultural waste water treatment
Agricultural wastewater treatment is treatment and disposal of liquid animal waste, pesticide residues etc. from agriculture.<ref name="EPA-agmm">Template:Cite journal</ref> Concentrated animal feeding operations (CAFOs) are a large contributor to water contamination with animal waste.<ref>Template:Cite journal</ref> A possible treatment to contaminated agricultural wastewater is extending rainwater drainage systems. Extending these systems allows room for water cleaning and collecting systems to be implemented. Another solution is reusing already treated wastewater from treatment plants. This diminishes any risk of the water being contaminated.<ref>Template:Cite journal</ref>
Industrial wastewater treatment
Industrial wastewater treatment is the treatment of wet wastes from factories, mines, power plants and other commercial facilities.<ref name="WEF-industrial">Template:Cite book</ref>
Sewage treatment
Sewage treatment is the treatment and disposal of human waste. Sewage is produced by all human communities. Treatment in urbanized areas is typically handled by centralized treatment systems. Alternative systems may use composting processes or processes that separate solid materials by settlement and then convert soluble contaminants into biological sludge and into gases such as carbon dioxide or methane.<ref name="M&E">Template:Cite book</ref>
Radioactive waste treatment
Template:Main Radioactive waste treatment is the treatment and containment of radioactive waste.
