The Garbage Guzzler uses aerobic digestion to process food and other organic waste. Bacteria inside the machine is heated until it becomes active and starts digesting waste inside the unit.
Once the digestion process starts, the bacteria produces heat, meaning it is self-sustaining and requires little, if any, energy to keep it at operating temperature. The high temperatures have a sterilising effect on the waste inside.
The bacteria is also self-replicating, and in most cases as long as it is fed a regular source of organic waste there is no need to keep adding new bacteria.
The first time through, waste is reduced by over 70% in volume and leaves an output that can be used as soil improver or biomass fuel.
Alternatively, the output can be put back through the Garbage Guzzler along with new organic waste to reduce it down further.
Repeating this process can reduce waste to virtually nothing.
