Creating energy from waste Back Dr Sharad Kale’s Nisargruna biogas technology has been used by many organizations to set up over 160 biogas plants. Sampurn(e)arth, one organization in Mumbai, tells us more What are the requirements to set up a biogas plant? Land along with 3 phase power supply and water supply. Segregation of waste at source to ensure only the organic portion is sent to the plant. Scope for usage of the gas. Capital investment (that usually pays off in 1 to 5 years). How much waste is needed for the plant? The plant is best suited for processing bulk quantities of waste, ranging from 100 kg to 30,000 kg per day. Multiple plants of these capacities can be set up to process an even larger quantity. Biogas plants have been set up at many educational institutes, industrial and corporate campuses, and hospitals and residential complexes. Several municipalities have also installed them for processing market or agricultural waste. What types of waste can be processed by this technology? There are many types: Food and garden waste Offerings made at religious places Biodegradable municipal solid waste Waste from fisheries and slaughterhouses Biomass generated from sewage plants What has been your experience with using the Nisargruna biogas technology? It has been pretty good so far. It has helped us do our bit in solving the mammoth problem of solid waste management in a sustainable, economically viable and eco-friendly manner. It has saved emissions of greenhouse gases from dumping grounds and those during transportation of waste to dumping grounds. The biogas plants have also enabled the institutions that have installed them to generate methane gas and nutrient-rich, weed-free manure. More institutions are gradually recognizing the value and possible uses of such gas—for cooking (by replacing LPG), for the generation of electricity, and by bottling into large cylinders for use in industries or vehicles. Moreover, the technology is quite easy to operate and therefore can generate employment for the marginalized sections of society, such as the thousands of women waste pickers who we believe are the invisible environmentalists of this country.
