The last stop for the urban ecologist. Mechanical Biological Composting units for fementing biological waste including human bodies. When you throw a man into the MBC -unit he gets composted, or actually fermented totally in two weeks. The unit is hermetically sealed so the whole process is anaerobic and computer controlled - so that the fermenting conditions for the anaerobic bacterias are perfect - the moist level, the heat and the preassure. From a 100 kg man you get 30 kg of top soil, the best. The rest is mostly water - biologically cleaned fresh water. The process also produces gases that can be collected into a gas conditioning plant that then feeds the electrical generator. 25 % of the electricity produced is enough to keep the whole process ongoing. The rest you can sell back to the city.
