Types of industrial waste include paper by-products, clay, stone, inorganic chemicals and organic chemicals. The category can also include plastics, food products, glass and concrete. Mining waste and waste from oil and gas production are specifically excluded from classification as industrial waste.
Industrial waste is classified as a kind of solid waste from business operations in industries like mining, farming and manufacturing. It can be classified as hazardous or non-hazardous. According to data generated in the 1980s, roughly 7.6 billion tons of industrial waste is produced and discarded every year.
Sewage treatment plants treat some industrial waste, but waste containing harmful pollutants requires special treatment options, such as industrial waste water treatment, to prevent groundwater contamination.
