Red Stripe - Lower Carbon, Lower Costs
Case study 31 JUL 2014
Our investment in more efficient plant at breweries like Red Stripe in Jamaica is saving energy and reducing costs.
Investment in the energy efficiency of our breweries can often bring several benefits at once, combining a reduction in carbon emissions with a reduction in our energy costs - a truly sustainable approach to making beer. Our Red Stripe Brewery in Jamaica is a case in point: in May 2014, we completed the commissioning of a £4m combined heat and power (CHP) generator designed to increase our energy self-sufficiency and allow the use of more sustainable fuels.
CHP plants are efficient because they simultaneously produce electrical and thermal energy from a single source by using the waste heat from electricity generation. The dual fuel CHP will initially use liquid propane gas, reducing the site's carbon emissions by 4,000 tonnes, or 25%, and saving an estimated £1.8 million per year. By 2016, the CHP will move to liquefied natural gas, saving a further 2,500 tonnes of carbon.
Further energy savings at the brewery, which makes brands including Guinness and Heineken as well as Jamaica's trademark Red Stripe, will come from improvements including more efficient cold rooms and fermentation tanks. The efficiencies are all part of our programme to halve our carbon emissions compared to a 2007 baseline.
