Coffee grounds, manure to fuel Nestle Swiss cogen plant

A biogas-fuelled cogeneration plant has opened in Switzerland and is said to be the nation’s largest agricultural biogas project.

The plant (pictured), developed by drinks company Nestle Waters and Swiss renewable energy project developer Groupe E GreenWatt, is located in the Treize-Cantons industrial park in the canton of Vaud. It is expected to supply 4000 MWh and 4500 MWth per year, with the heat supplied to the nearby Henniez mineral water bottling plant. à‚ 

Fuel for the anaerobic digestion installation will consist of 25,000 tonnes of manure from local farms as well as 3800 tonnes of coffee grounds produced in the manufacture of Nestle’s Nespresso and Nescafe coffee brands. à‚ 

The new plant is expected to reduce Nestle’s carbon emissions by 1740 tonnes per year, advancing the company’s goals to cut emissions from its Swiss facilities in half by 2020 compared to 2010 levels, and to achieve zero-waste operation. à‚
