Toilet waste to energy system | Wyly Wade
B747 toilet (Photo credit: Wikipedia) It may not be an appetizing thought when you're putting the dinner on - but a new loo turns human waste into fuel. The 'No Mix Vacuum Toilet' is an airplane-style vacuum toilet which splits waste into solids and liquids. Liquid waste is processed for chemicals such as phosphorous for fertilizers. Solid waste is processed in a bioreactor to create 'biogas' - a methane-rich gas which is, the scientists promise, odorless and safe for cooking. Canny scientists have invented a new toilet system that can turn human waste into electricity and fertilizers, 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 airplane toilets. Solid waste will be sent to a bioreactor where it will be digested to release bio-gas which contains methane - an odorless gas used to replace natural gas used in stoves for cooking
