U.S.-based OriginOil and France-based Ennesys have teamed up to develop a process that generates electricity using wastewater.
So it doesn’t just provide a cheap, sustainable energy solution… it also recycles waste at the same time.
The key to making this happen? Algae.
The process is currently being tested on an office block in Paris. Essentially, wastewater from bathrooms and kitchens flows into flat-panel bioreactors, where the algae is grown within 24 to 48 hours. At that point, fuel is extracted from the biomass to power the building.
This is especially useful in places like France, where builders “now have to show more energy coming out of the building [than] is going in, and they have to clean the sewage water,” according to OriginOil’s CEO, Riggs Eckelberry.
But as carbon emission regulations become stricter worldwide, it might not be long before we see similar projects pop up around the globe.
