Researchers at Cranfield University, UK, have come up with a green toilet, which is cheap, easy to maintain, needs no water to operate, and is capable of turning human excrement into electricity and clean water. […]
Eawag, the Swiss Federal Institute of Aquatic Science and Technology, recently developed a new and highly efficient composting toilet called Blue Diversion. Human waste has significant value, since it can provide fertilizer and phosphorus and the Blue Diversion toilet is able to successfully harvest both. These byproducts can also be sold at a profit, so this toilet does more than just provide water efficiency or off-the-grid-living.
