Waste-to-energy is very similar to bio-mass electricity production, although specifically used with municipal waste.

Energy recovery from waste is the conversion of non-recyclable waste materials into useable heat, electricity, or fuel through a variety of processes, including combustion, gasification, pyrolysis, anaerobic digestion, and landfill gas (LFG) recovery.

With the increase of the population in the cities of Africa, household waste management is a major issue with its effects on public health. Solutions are based on burial or valorization of waste, either by recycling or combustion. Considering the limitations of recycling, combustion with environmental standards is an advantageous solution to bridge the energy deficit in many countries in addition to being a renewable energy source that reduces burying and carbon emissions into the atmosphere by replacing energy needs from fossil sources.
