Project Dates: 2013 to 2017


Nutrient rich spent litter is typically stockpiled for composting before land application. Key concerns with this handling are uncontrolled greenhouse gas emissions and nutrient leaching. The solid phase leachbed (solid-phase anaerobic digester) has been identified as a potential anaerobic digestion technology for on-farm treatment of solid manure residue, as it is simpler and cost-effective compared to technology alternatives and promotes energy and nutrient recovery from waste. This project will study the performance of pilot-scale leachbed (200L) for treatment of spent litter from piggeries for decentralised agriculture application.
