Major international brewing group Scottish and Newcastle (S&N) has awarded two contracts to Wärtsilä for the supply and installation of two biomass-fuelled combined heat and power plants (CHP).
The contracts are for CHP plants to be located on the premises of the company’s UK breweries in Manchester and Tadcaster.
The Wärtsilä BioPower plants will be the first power plants in the world to produce heat and power using spent grain, a by-product of the brewing process, as fuel.
The CHP plants will each have an output of 7.4 MWth and 3.1 MWe and will burn a mixture of spent grain and wood chips from local sources. The facilities 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 grid.
‘The Wärtsilä BioPower plants will enable Scottish & Newcastle to make more efficient use of residue from its beer production, cut down on waste handling and energy costs, as well as reducing CO2 emissions,’ said Tauno Kuitunen, Regional Sales Director of Wärtsilä Biopower.
