Anaerobic Digester to convert Household Organic Kitchen Waste to Biogas: Interventions for 'Swachh Bharat'

Biodegradable wastes from kitchen contribute significantly to pollution, which demands immediate management and treatment. The technology for converting household organic kitchen waste to biogas was developed by CSIR-National Institute for Interdisciplinary Science and Technology (CSIR-NIIST), Thiruvananthapuram. Each anaerobic digester has the capacity to convert up to 3 kg per day bio-degradable kitchen waste which will be converted to 400 litre biogas which can be used as fuel. In the process, it will discharge about 2.5 litres of manure which can be used for kitchen garden. The technology has been transferred to Pune based company, Mailhem Ikos Environment Pvt. Ltd. and will also be utilised by Thiruvananthapuram Corporation.
