The expansion of cities in Rwanda and the increase of settling of people in town lead to the increase of municipal solid waste that reaches 0.5kg per capita and 800tons per day in only Kigali city which is harmful to environment and source of diseases and leachate. Without practical gas capture and recovery facilities of the landfills constructed, the greenhouse gases would emit to atmosphere totally during the anaerobic and aerobic biodegrading procedure of the carbon origin material including methane, carbon dioxide, hydrogen sulphide and nitrogen components. Waste Power Plant Ltd (WPP) is a coming quick fix to municipal solid waste and a tool for energy recovery.
The 50% of the plant is environmental protection through incineration of 480 tons of Municipal Solid Waste per day and treatment of solid waste, liquid waste effluents and gaseous from low material will eliminate their environmental effects. The 30% of the plant is unemployment reduction by employment of 323 permanent workers and 207 during plant installation and different international and national companies with associated local warehouses for implementation. For energy recovery which is 20% of the plant the hot flue gases from the furnace would flow through the boiler, releasing thermal energy which turns water into steam. The steam produced would be used to drive the turbo alternators for electricity generation.
The plant is multipurpose on municipal solid waste and environmental protection, it will reduce greenhouse effect and unemployment problem, and continuously produce 15MW in national and regional grids.
