After CNG, the national capital is all set to run its public transport fleet on biogas. Ambitious as it may sound, but Delhi plans to run its buses on biogas. In collaboration with the Swedish government, the Union Ministry of New and Renewable Energy plans to set up a biogas plant inside Kesopur Sewage Treatment Plant (STP) complex in West Delhi. The plant will receive raw gas emitted by the STP and upgrade it so that it can be used to propel vehicles.

Large-scale research facilities need to reduce their energy consumption and begin moving towards sustainability, says Thomas Parker.

They are registered as clean development mechanism projects, eligible for carbon credits. On October 15, 2010, the regional officer of Chhattisgarh Environment Conservation Board (CECB), R K Sharma, visited Tilda industrial area in Raipur unannounced. He noticed thick smoke rising from the premises of a renewable energy project. On paper the 8.5 MW power plant, Agrawal Renewable Energy Project, uses rice husk, a cleaner alternative to coal, to produce electricity. The electrostatic precipitator (ESP), an emission control device, installed in the plant was tripping frequently.

Increasing urbanisation and industrialisation has increased the amount of waste generated, leading to a greater need for scientific waste management. Due to the presence of high organic matter in industrial and, specifically, urban waste products, generating power from waste is a potential solution to the problem of both waste management and clean energy generation.
