Fecal sludge extraction and disposal system in situ

2011 - 2015 • Beijing Sunnybreeze Technologies Inc
project database

Purpose

Disposal of human waste in situ by an column-like facility; evaporating liquid from raw sewage powered by solar-thermal energy; removing pathogens by raising temperature over 140C

Activities

Disposal human waste in situ by an column-like facility; Evaporation liquid from raw sewage powered by solar-thermal energy; remove pathogens by raising temperature over 140C; preferred on existing, inexpensive, practical, multi-disciplinary techniques and methods to solve the great challenge in limited term.

Phase II proposes a waterless toilet with a complete Mini Waste Processor (MWP) that dries and sterilizes the human wastes in an automatic system. The liquid portion of the human waste is evaporated and the solid portion of the fecal sludge is heated in the evaporator/dryer/sterilizer of MWP. This unit removes the pathogens and transforms the waste into a dried form that is usable as a fertilizer.
