India's first community power plant

A 200 kWh hydro-electric power plant has been commissioned in a village in Nagaland. Running and maintenance of the plant has been left wholly up to the village councils - a surely positive move towards self empowerment. A gassifier unit has also been commissioned on a similar basis in another village, to produce electricity out of firewood. Gassifiers, although expensive, leave zero residue upon consumption of raw materials - another clean energy production method. Can the same techniques be used for gassifying garbage heaps, instead of the traditional methods for sludge treatment and biogas power production?
