The ultimate recycling program will see every bit of our societal waste re-entering the stream as an alternate power source.
Biopower, including direct combustion, co-firing, and anaerobic digestion, is the production of electricity or heat from biomass resources.
Most electricity generated from biomass is produced by combustion by burning these resources, producing steam which drives a turbine that activates a generator that produces electricity.
Co-firing, on the other hand, involves replacing a portion of the petroleum-based fuel in high-efficiency coal-fired boilers with biomass. The main advantage is that it reduces the sulfur dioxide emissions of coal-fired power plants.
Finally, anaerobic digestion, or methane recovery is the kind of organic breakdown that goes on in our backyard composters and produces heat and with other technologies added, electricity.
