Engineered Ecosystems for Waste Management Salient features of process are: Organic wastes from human Engineered Ecosystems for Waste Management Salient features of process are: Organic wastes from human and animal habitations can accumulate in, and endanger the environment. Engineered ecosystems research for waste conversion has led to the development of Vermiculture Technology at IIT Bombay. This process overcomes the problems associated with conventional methods such as solid state composting, activated sludge, and extended aeration in which bio-energy gets dissipated. It engages an ecology consisting of soil, plants and soil micro and macroorganisms including geophagous earthworms. The process obtains synergy between photosynthesis and respiration, so that bio-energy of wastes is fully utilized. Facilitated through initial support by the Department of Biotechnology, the process has major potential in city farming, animal husbandry, agriculture, wasteland development, and agro-industrial waste processing.

Dam project - Karjat Two sites of Gudwanwadi and Belachiwadi have been selected initially Dam project - Karjat Two sites of Gudwanwadi and Belachiwadi have been selected initially for the current year and next year respectively, along with nearby hamlets of Amberpada, Kathewadi. The dam for Belachiwadi will be roughly 80 m in length, with a 20 m spillway and a maximum height of 8 m with storage of about 30, 000 cu. m. The survey and study of the sites has been done by the Earth Sciences students and CSE students have developed a geometry code on Gram ++ developed by CSRE for watershed/storage estimation. Civil Engineering researchers will undertake Geodesy, Dam Design, Construction and Analysis. Humanities and Social Sciences staff and students conduct a need analysis, site selection and social analysis. ADS will be responsible for the social mobilization, local support and execution getting technical consultancy from Gangotree, an agency with considerable experience in social watershed development. Rough estimates for the dams are Rs. 12 lakhs for Belachiwadi and Rs. 18 lakhs for Gudwanwadi, A large donation of Rs 20 lakhs by IITB alumni, Dr Shridhar Shukla, of G S Labs, Pune has helped taking this initiative further.

Briquetting Machine • Different kinds of fuels are used for heating purposes. In rural Briquetting Machine • Different kinds of fuels are used for heating purposes. In rural areas most of the people use fuel-wood for cooking and heating the water. The large scale use of fuel-wood has led to the deforestation. • In a view to conserve the forest, alternative fuels such as briquette can be used for every day heating works. Briquettes are made from dried leaves, dung, saw dust etc. • The mixture, prepared by adding sufficient water, is placed in the mould and it is compressed by hand lever. • • Two person can make 25 – 30 briquettes in an hour. Density of briquettes made in the hand briquette machine is around 500 – 600 Kg/m 3. . Dr. N. G. Shah, CTARA, IIT Bombay

Rain Water Harvesting Structure There is heavy rainfall in Konkan region; however, water run Rain Water Harvesting Structure There is heavy rainfall in Konkan region; however, water run away on the slopes and very little water (around 18%) is left for the use. Hence, people face severe scarcity of water in summer season. Six houses are constructed around the sides of the hexagonal water tank. When the rain falls on the roof of the houses, it runs away on the roof and gets deposited in the tank. The capacity of water tank is 1. 2 lakh liters. Considering the per capita consumption of 25 lit/day, water stored in the tank will be enough for six families for four months of summer season.
