- The shredder rips up waste
and soaks it in water.
- The sludge is pumped into the bioreactor, and enzymes break it down into carbohydrates and then into simple sugars, which yeast metabolizes into ethanol.
- The pelletizer compresses undigested waste into pellets and feeds them into a gasification reactor that burns them to produce a composite gas.
- The ethanol is combined with the composite gas and injected into a diesel generator, where it's mixed with 10 percent diesel fuel to generate electricity.
