Kinetic study and optimization of total solids for anaerobic digestion of kitchen waste: Bangladesh perspective

Kitchen waste from hotels and homes is one of the major problems for urban and rural environment and could be one of the best sources of renewable energy by producing biogas through anaerobic digestion. A research work was undertaken to assess the methane potential of kitchen waste at different tota...
