Houses That Run on Crap...literally.

So you thought the poo from your butt was totally useless, huh? THINK AGAIN...sucka!
Using biowaste as fuel and harvesting methane emissions from cows isn't anything new, but if the process can be taken to the mainstream and in a large scale it can really diversify the gas and electric supplies. the company British Gas strongly believes this process could influence other companies to using their poop as power as well.
Over 200 homes in Didcot, UK are now being heated with human waste! Before you lose your lunch, allow us to explain that the waste is highly purified at a nearby sewage station and converted into an odorless gas before being used in the homes. The process to make gas from human waste takes about 3 weeks and involves using anaerobic bacteria to ‘digest’ the sewage and produce methane. Once the gas is created, it is collected and either delivered to households or used to produce electricity. In the UK, an estimated 1.73 million tons of sewage sludge is produced annually. This amount could supply enough gas for 350,000 households if used according to the technology. In larger countries, even more could be produced. Currently, the project is worth about $4 million and was partly funded by government incentives that aimed to make utility companies use and adopt renewable energy methods. As with the UK’s installation of wind farms and other sustainable efforts, the poo-powered homes are all part of the country’s initiative to get 20 percent of its energy from renewables by 2020.
