An abandoned farmhouse in northern Spain is being renovated to be powered entirely by poo. Designed by Meghan Sapp and her startup renewable energy company Planet Energy, the Spanish House of Poo will be a completely self-sustaining eco-house that uses waste produced by from its human and animal inhabitants to generate renewable energy.

California-born Meghan Sapp is proving that harnessing the power of poo on an individual level is possible. She and her partner, IƱigo Arana, will renovate the farmhouse so that 100 percent of all household waste, including human excrement, will be converted into biogas. Through the process of anaerobic digestion, the biogas will provide more than enough energy to heat the home, provide hot water and even power the stove.

Sapp explains that although we’ve already seen poo-powered buildings and cars on a somewhat large scale, it’s important for individual homeowners to take advantage of the waste system, “This is a demonstration facility, to show people that it’s technologically and economically viable on a small scale. Anywhere up from here, it’s doable.”

Sapp and Arana will live in the eco-farmhouse once the renovation is completed. As far as the cost of the project, which includes renovating the structure while installing the integrated waste system, the couple will invest approximately $536,000. The project is currently ongoing and is slated for completion in spring of 2016.

“The investment in the energy system amounted to around 20 percent of the outlay,” she admits. “But we are looking at a pay back within four and a half years”.

Of course, Sapp and Arana aren’t only focused solely on poo. Their startup is working on a proposal that would see apartment complexes in Spain recycle waste for energy. They are also in talks with local wineries and cheesemakers to use their agricultural waste to power their operations.
