Municipal Solid Waste (MSW) generation, often called MSW, uses direct combustion technology to combust garbage. This process first involves separating out combustible garbage. Then, the garbage is incinerated in a furnace or fluidized bed combustor to create heat. The heat is used to create steam for use in a steam turbine. Although the feedstock of MSW does not come directly from biomass, MSW generation is often treated as biopower for regulatory purposes.
