BioFAVOR II – Recycling of human feces from decentral sources by a novel low-tech process

Human feces are considered a waste which remains nearly unused. Currently, its disposal requires high amounts of energy and involves contamination of high quantities of fresh water. In countries like Germany the costs for disposal are especially high in places where no connection to a water-based sewer is available and if accumulation strongly fluctuates, e.g. at festivals, construction sites or camp sites. On the other hand side the utilization of feces from these decentral sources as resource is very promising from an ecological and an economical point of view.
Our aim is to provide a technically and socio-economically feasible solution for the decentral sanitation of feces and their conversion into a bio-based product. In frame of the project BioFAVOR II we aim to demonstrate the technical feasibility of a novel low-tech process, which is easily scalable, mobile and allows for the valorization of human feces.
