New toilet turns your waste into odourless gas for cooking

From The Daily Mail

Canny scientists have invented a new toilet system that can turn human waste into electricity and fertilisers, and reduce water for flushing by up to 90 per cent.

Coined the No-Mix Vacuum Toilet, the loo has two chambers that separate the liquid and solid wastes - and uses vacuum suction technology like aeroplane toilets.

Solid waste will be sent to a bioreactor where it will be digested to release bio-gas which contains methane - an odourless gas used to replace natural gas used in stoves for cooking.

Flushing liquids in the new toilet would only take only 0.2 litres of water and flushing solids requires one litre, compared to four to six litres in a conventional loo.

According to the inventors, if it is installed in a public restroom and flushed 100 times a day, it will save 160,000 litres in a year - enough to fill a small swimming pool.

The No-Mix Vacuum Toilet will divert the liquid waste to a processing facility where components used for fertilisers such as nitrogen, phosphorous and potassium can be recovered.
