A Swedish company is selling dry toilets to help countries where water or sewerage systems are a concern. These toilets work by keeping the urine and the solid waste separate and using the second to create manure for farms. So far, the company has sold about 2,000 dry toilets, but the demand is growing worldwide.

Here are some short excerpts from the India News article.
‘Don’t mix, don’t flush, don’t waste’ is the slogan of a Swedish entrepreneur selling dry toilets – a revolutionary concept that not only saves water but also converts human waste into manure.
Sven Ingvar-Nilsson, 77, has been successfully using the dry toilet design for the last 11 years at his massive farm on the outskirts of this small Swedish town. He says that the concept not only uses human waste but also saves a lot of water that is wasted every time you flush.
The urine section is rinsed using approximately 0.1 litres of water each use. The urine is led to a tank where it is collected for further transport, preferable for spreading as fertilizer in garden or agriculture. Solids fall into a bin housed in an insulated container in which negative pressure is created by a fan and vent.
The solid waste dries and thus bacteria and viruses are eliminated by a simple and reliable method. After a drying period of six months the solids can be composed, burned or dug down in the soil where it is quickly broken down. A standard bin (holding 80 litres) will need to be emptied every three months for normal family use.
