Disposal of Solid Municipal, GramPanchayat, Domestic and Hospital Biomass Waste Through use of Incinerator, And Energy for Heating Water : In present condition solid waste management is a big issue, the solid waste is generated at domestic, commercial and agricultural levels which is to be managed and treated in a proper manner so that it can  be used as energy source and also be less polluting. The traditional systems of dumping solid waste causes land pollution and the process of burning solid waste causes air pollution which is not desirable. Solid waste incinerator is the most useful device for managing wastes and it is the desirable technique which can be used for disposing all types of hazardous wastes. At domestic level such as house, the waste such as plastics, clothes, packing materials, cardboard, paper, garden wastes, Coconut wastes, etc. are not disposed properly. And if this is the condition of a single house then what would be of one city and that of whole country we cant imagine. This waste is just taken and dumped at the places out of city which causes the land pollution or burned which causes the air pollution. This condition can become critical if proper steps are no taken before its too late.

Aditya Home Light

Aditya Home light system is a Solar power based distributed system which is operated and maintained by women entrepreneurs. The system consists of a solar power central charging station. The central charging station consists of a custom built 14V storage battery which is charged by two Solar PV panels of 35 watt each. The charging station can charge 10 lamps at a time. The lamps use 6V battery for powering 2 watt LED lamp and give 30 lux at a distance 1.5 meter. These lamps do not have any electronic component and are easy to maintain. The system is owned, managed and maintained by a woman vendor. Before installing and handing over the system, the vender undergoes extensive training at SRI on operation and maintenance of the system. The system operates on a rental basis. The vendor is given 20 lamps along with the charging station. She rents out these lamps at Rs. 2.50 per days. For a set of 20 lamps the vendor earns about Rs. 50/- a day. The user takes the lamp in the afternoon and returns it for charging in the morning. The main beneficiaries of these lamps are children. These lamps have been specially designed for focussed area lighting suitable for study not for special illumination.

Biomass Charcoal Briquetting from different agrowaste

This technology addresses the management of agro waste generated during agricultural operations and converting them as useful products. This technology was adopted from ARTI, PUNE during 2006 and modified for easy operation. A prototype model kiln was developed during DST Young Scientist Programme with slight modification which was again modified with a portable cylindrical prototype kiln with basal perforated plate and air vents and tested for efficiency. The prototype kiln model (furnace) was fabricated at the local work shop. The advantages of the modified kiln is that the carbonization is uniform, higher char yield, lesser process time, easy to operate and maintain and easily viewable during carbonization. The optimum conditions of carbonization of different biomass, available at different localities and their calorific values were studied. Since some kind of biomass will be available in every location, the beneficiaries can utilize this technology to produce charcoal briquettes from the biomass available in their locality for their income generation. Biomass charcoal briquettes were tested for cooking experiments at beneficiaries’ house, local teashops, laundry and small hotels in Chennai. Apart from fuel briquettes production from charcoal, a value added product from biomass carbon was developed. Along with charcoal powder, other natural ingredients were added and sambrani (Incense) pellets were produced. This technology package was disseminated to beneficiaries through 5 networking NGOs. In a community, if 4 beneficiaries work together, they can make a net profit of Rs 11 /kg of charcoal briquettes and Rs. 173/kg of incense sticks. Awareness programs were conducted to 8 Networking NGOs. The dissemination of the technology is in progress.
