Expertise: Waste Management

Biography: Lakshmikanth worked as a Research Scholarin the Centre for Sustainable Technologies in the Indian Institute of Science, Bangalore for the past five years. He obtained Bachelor of Engineering and Master of Engineering degree from Anna University during 2006 and 2010 respectively. He joined Indian Institute of Science in 2010 as Ph.D student. MyPh.D topic is “Study of the engineering properties of municipal solid waste for landfill design”. Presently he is working as Senior Research Associate in the Indian Institute of Science and  working on various projects in landfill engineering, waste containment, contaminant transport, site remediation, waste to energy and waste minimization. He had worked on topics like engineering properties of waste, engineered waste management, Life cycle analysis and bioreactor landfills. He had also worked on several models like the LDAT model and constitutive models.,

Title: The Municipal Solid Waste Management Practices In India and Bioreactor

Abstract:

MSW rules in India specify that biodegradable wastes should beprocessed by composting, vermi composting, etc., and landfillingshall be restricted to non-biodegradable inert waste and compostrejects (Municipal Solid Waste Rules, 2000). Several pre-treatmentmethods like composting, refuse derived fuel havebeen developed in recent times in order to recover thematerials and to minimise the organic content reaching the landfills. This study analyses effectiveness of each pre-treatment method adopted in India and elsewhere.The basic and engineering properties of waste collected from different landfills and composting sites in Bangalore are studied. Lab scale setups have been fabricated to study and analyse the potential of bioreactor in comparison with the other treatment methods. Theimpacts of leachate from waste, landfill gas (LFG) generation, leachate characteristics and long term waste settlement have been monitored and analysed in the setups for over a period of 365 days. The results showed that anaerobic bioreactor through leachate recirculation could be potential waste management and treatment option that could reduce risk and damage to the environment and move towards sustainability.
