Portable evaporative off-grid toilets don’t need plumbing, water or electricity

in #technology6 years ago (edited)

This is a low-cost, off-grid, compact, environmentally safe toilet able to evaporate 95% of sewage sans energy with the help of a simple polymer membrane.

Users wouldn’t need plumbing or water to flush the toilet. The membrane acts like a sponge, “soaking up and accelerating the evaporation of liquid contents without the use of power or heat.

These toilets have the potential to help reduce violent attacks on women and girls, prevent disease, help improve school attendance by girls, and bring much needed dignity to a simple act which is yet to be taken for granted.

In off-grid places like refugee camps or disaster-struck areas, where there could be lack of water, plumbing and sewer infrastructure, this could a sustainable solution.

The vapours released are pure clean water, while the dried solids left behind are safely contained inside the membrane.

This volume reduction means toilets only have to be serviced once or twice in a month.

The toilet sends waste water back into nature “in its purest form” in an attempt to promote a “cycle of use and re-use in a more efficient, sustainable, low-carbon way.
