Industrial waste and it's types
Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process of factories, mills and mines. Or Industrial waste refers to the solid, liquid and gaseous emissions, residual and unwanted wastes from an industrial operation. Industrial wastes are hazardous since they may be toxic, ignitable, reactive and leading to extensive pollution. Among the great variety of industrial wastes that are generated gases, acids, metallic compounds, oils, radioactive and complex synthetic chemicals.
Types of Industrial waste
To some extent, people divide industrial waste into 2 major categories: waste from heavy industry and waste from light industry. It contains a wide range of complex components. To simplify, put them into 3 core states: solid, liquid and gas.
Solid waste
Liquid waste
Gaseous waste
Solid waste
Solid waste refers to non-soluble material such as agricultural refuse, industrial waste, mining residues, demolition waste, municipal garbage or even sewage sludge. Solid industrial waste generated from processing plants and factories such as metals, chemicals, plastic and building materials. If these wastes are not properly disposed or recycled, certainly, they will be dropped out the surrounding environment and then damage people’s lives
Liquid waste
Liquid waste can be defined as the presence, of some foreign substances or impurities (organic, inorganic, radiological or biological) in water in such a quantity so as to constitute a health hazard by lowering the water quality and making it unfit for use. The origin of liquid industrial waste is oil refinery, cement, fertilizers, paint and rubber industries, sugar mills, cooking oil factories, paper manufacturing plants and food processing plants etc. Waste from these industries mainly contains hazardous material and contain hundreds of toxic chemicals which are discarded to rivers, lakes and seas. Every year, there are so many circumstances of liquid waste that cause severe damages to both human health and environment.
Gaseous waste
Gaseous waste is defined as uncontrolled airborne emissions and effluents. These emissions consist of gas, mist, smoke, vapor, matter, fumes or any combinations. Gaseous waste primarily comes out as a result of industries such as manufacturing, processing and consumption of various materials. Gas industrial waste comes from internal-combustion engines, thermal power stations and manufacturing plants and mostly released from chimney of industries.
