“Powering a village sustainably: generating electricity from waste-based biogas”

This project, in Ramanagara district of Karnataka state (south-west India), demonstrates a case of sustainable rural access to energy-services through a community enterprise that generates electricity from the waste of an integrated income-generation activity.

The village energy-development enterprise comprises a dairy, a biogas plant with a 35 m3 floating-drum digester that is fuelled with the dairy waste, a 20kVA engine-generator fuelled completely by biogas from the linked plant, the extension of the electricity distribution system to un-electrified homes, and through these, daily electricity supply to the households and other consumers in the village.  The dairy provides employment and income.  Cattle dung serves as sustainable fuel-supply for biogas-generation.  The biogas-digester effluents are used as manure.

The provision of electricity through the biogas-fuelled system is continuing as intended.  Supply to the village enables lighting and other electric devices in homes and community needs such as street-lighting and pumping water for domestic use.  Electricity is usually supplied for an hour in the morning for water pumping and for two-three hours in the evening, for lighting and the other electricity-enabled services, when the Bangalore Electricity Supply Company (BESCOM) service is not available.

The project was financially supported by the Wuppertal Institute for Climate, Environment and Energy, through the 6th round of their Sustainable Energy Project Support [SEPS].

Value-addition to food crop processing: converting banana plant-waste to cooking fuel”

The establishment of this rural energy-enterprise is in progress.  It is another rural demonstration of improved (cleaner, more efficient) energy services, based on a renewable fuel that will be derived from the waste of a locally established income-generating activity.  Residues (pseudo-stems, leaves, etc.) from banana plantations will be chopped for anaerobic digestion.  The biogas so generated will be supplied to the surrounding households as cooking fuel.  Hence, food-crop-residues will be converted to cooking fuel, financed by enhanced crop revenues.

Banana-plantations of tissue-cultured saplings have been developed at four small subsistence-farms in Ramanagara district of Karnataka state.  Irrigation-facilities were provided to enable their participation in the cultivation; these costs will be recovered over time through shares of the banana harvest.  Plantation was carried out in batches so that the plants are at different stages of growth. 

Two biogas plants are being constructed adjacent to the clusters of households who want to purchase biogas.  The digesters are being completed in situ while the gasholders will be completed outside and transported to the village.

This project has been selected for funding by the Wuppertal Institute for Climate, Environment and Energy, through the 7th round of their Sustainable Energy Project Support [SEPS]. .
