In India various kinds of wastes which include industrial effluents (as paper pulp or other industrial chemicals), sewage and other systems and thermal pollutants(waste water) etc. may be recycled to generate cheaper fuel gas and electricity. The NEERI in India could develop technology for management of radioactive wastes and chemical wastes of atomic power plants, reclamation of waste water and to supply cheap piped gas and generated electricity by recycle of urban waste. In Okhla, New Delhi, one large treatment plant for sewage recycle is already in operation. NEERI is also involved in utilisation of domestic and industrial waste water in agriculture by biological means.
