2015 - Present | ...Rebranding 'waste' as a 'resource'...
Safely reducing the volume of municipal sewage sludge typically sent for processing by sewer avoidance via separation at the source/on-site remediation of humanure using compost toilets with urine diversion AKA humus (top soil factories). This sanitary compost schema uses the 2018 IAPMO WE-Stand Guidance rubric. Ultimately, a rich resource is generated that can be used as a soil amendment to grow food by tiny house stewards managing hyper-intense farming on tax-defaulted, urban lots.
Conducted over four years, performance of a humanure batch compost processor, clearly demonstrates that high temperatures were reliably achieved with subsequent pathogen elimination to acceptable levels prior to distribution of high quality humus to the local garden environment. Additionally, urine diversion has also allowed the community to reclaim nitrogen and other nutrients otherwise lost in conventional sewage systems. The system has resulted in large savings of potable water, and significant carbon sequestration.
