[font size=3]Work on a prototype device for harvesting energy and clean drinking water from human waste gets the go ahead this month.
A project from a team of researchers from Imperial College London, the University of Manchester and Durham University beat more than 2,000 other proposals to receive funding from the Bill and Melinda Gates Foundation to develop a prototype system for recovering drinkable water and harvesting hydrogen energy from human faecal waste. The researchers believe the technology could provide an inexpensive device for people in the developing world to generate clean water and energy from waste and a sustainable source of hydrogen energy that could be used to power homes in developed countries.
The researchers say that the device will be portable, allowing installation in homes and remote locations. The technology is based on a porous scaffold that holds bacteria and metal nano-particles. When faecal sludge is filtered through the scaffolding these particles will react with the waste mater to generate the recycled resources. These can either be used immediately or stored for later use.
The first stage of the project will see the team developing a stand-alone sanitation device, making it easier and cheaper for people in developing countries to adopt the technology where large sewage networks may not exist. Where sewage infrastructure is in place, the technology could be hooked into the system, minimising implementation costs for home owners.
