Heineken UK goes green with biomass plants Heineken UK has invested £35 million in two biomass plants with the capacity to produce green electricity and thermal energy. World ofHeineken 41 winter 2009 "The project is extremely important for Heineken UK as it demonstrates our commitment to improving our environmental footprint," said Richard Jeffers, Heineken UK's Engineering Manager. He points out that the plants represent one of the largest single investments in renewable technology by a non-utility company in the UK. Construction of the biomass plants, one at Royal Brewery in Manchester and the other in John Smith's Brewery in Tadcaster, started in the middle of 2007. The plants have been fully operational since October this year, and expert teams at the sites are closely examining the realisation of the new technology in order to further optimise the plants in the future. The plants use wood chips, originating from sustainable forests within the UK, in their boilers to produce steam, which in turn produces electricity. While this is the technology currently in use, both plants also have the capability to generate energy from spent grain originating from the brewery's used malt. "The spent grain is currently sold as animal feed, but in the future we plan to also use it as a source to produce energy," Richard says. The Manchester and Tadcaster plants each have the capacity to generate up to 37.000 MWH (megawatt hours) of electricity a year, which covers the breweries' electricity usage. Any excess electricity generated will be sold back to the National Grid, the country's power transmission network. Richard points out that the investment in the biomass plants also "makes good commercial sense, providing protection from the volatility of the energy markets, as well as offering additional security of supply." In addition to producing electricity, each plant also has the capacity to generate up to 70,800 MWH of thermal energy annually. This amounts to 60 per cent of the thermal energy needed by the breweries in a year for the brewing and packaging processes. Work is ongoing at both sites to maximise the benefit of this heat either within the site, or in combination with usage by the local community through district heating schemes. The two plants are expected to reduce carbon emissions by 30,000 kilo tonnes per year. "This is because the energy produced by the plants comes from renewable sources instead of fossil fuel." richard.jeffers@heineken.com 25
