Wartsila Plant Uses Brewery Spent Grain

Wartsila has been awarded two contracts by Scottish and Newcastle (S&N), the major international brewing group, to supply and install equipment for two biomass-fueled combined heat and power plants (CHP). The two CHP plants will be located on at the company’s UK breweries in Manchester, for which the order was received in the end of 2007, and Tadcaster, for which the order was received in the beginning of 2008.

The CHP plants will each have a thermal output of 7.4 megawatts thermal and an electrical output of 3.1 megawatts. Wartsila’s plants, which will burn a mixture of spent grain and wood chips from local sources, are due to start operations in the first and second quarters of 2009, producing steam and electricity for the breweries’ processes and exporting excess electricity to the local electricity network.

“These projects are extremely important to our company in that they are a real demonstration of our commitment to improve our environmental footprint. Additionally, we believe the investments make good commercial sense, providing some protection from the volatility of the energy markets, as well offering additional security of supply,” said Andrew McMurtrie, Project Manager at S&N.
