Waste water management
Mediterranean countries produce lots and lots of olive oil which is great. What’s not so great is the amount of wastewater that comes with it. There is no sustainable way of getting rid of this waste product. By combining the wastewater with cypress sawdust and putting it through a process of drying and heating, they managed to produce three things: water that can be used for irrigation, a bio-oil that works as a source of heat, and biofertilizer pellets. Not only will this invention help the planet but it will also benefit local communities especially farmers.
