In the Ennesys Lab in Nanterre, France, researchers are working on a project to produce energy from waste water by cultivating micro-algae in order to heat water and provide heating.
Waste water contains organic pollution and this makes an ideal fertilizer for micro-algae which given the correct amount of light will flourish and grow.
Jean-Louis Kindler, Director General of Ennesys explained: “We collect waste water from this building and we dilute this water so that micro-algae can live in it and consume the pollution found in waste water. The micro-algae grows and then we separate them and produce oil and vegetable biomass which is recuperated. This oil can can be used as a fuel as we’re doing here with this lamp, to produce energy either in the form of heat, or in the form of electricity. Here, feel the heat.”
