The alternative scenario processes source-separated waste from UDDTs. Feces is broken down by a grinder before being processed by the Biogenic Refinery and urine is processed to recover nutrients for fertilizer through struvite precipitation, ion exchange, and a liquid treatment bed. Both scenarios utilize the Biogenic Refinery for solids treatment. The refinery has three main assemblies: the pyrolysis base, the pollution control device, and the heat exchangers. Solids are placed into the carbonizer base and exposed to a high temperature, low oxygen environment for the combined pyrolysis and combustion process. The pollution control device reduces emissions and improves thermal energy efficiency for the heat exchanging system. Thermal energy within the refinery is utilized for generating electrical energy via the oil heat exchanger and drying of feedstock via the hydronic heat exchanger. In both scenarios, it is assumed a single Biogenic Refinery serves up to 12,000 daily users (community-scale) with an expected lifetime of 20 years.
