Toilet (r)evolution ahead

toilet evolution

.

Following the previous post, here is a example of a different approach:

.

We are trying to improve on everything, as for instance drinking water use in sanitation. New technologies are developed, but the problem solving is in most cases single issue oriented: the water use is reduced, but other resource use in increased, shifting and even increasing burdens. Like for instance with no-mix toilets, or vacuum toilet systems :” technology solves problems technology created”. If we however include all resource impacts, the solution will be somewhere else: not extrapolated from an existing situation (“technology push”), but going to the roots and reinvent a low tech solution. In the “toiletcase” the most effective outcome is compost toilets: Stand alone, no water, no material, no energy impacts ( except in production, which could be from biobased plastics) , and providing compost for local gardening, and Urban farming.
