BREWERIES can successfully utilise the biogas from their wastewater treatment plant as an energy source in their operations, saving money as well as minimising waste, according to environmental solutions company Talbot & Talbot.The company says that the biogas produced from the treatment of wastewater can contribute 10-15 per cent of a brewery's steam requirements, reducing the need to buy increasingly expensive alternative fuels while substituting it with 'green' energy.
Using biogas as a fuel for raising steam in a brewery can definitely be viable, resulting in the treatment plant changing from a cost centre into a profit centre. The value of this energy depends on the cost of the current fuel it replaces, whether coal, gas or electricity.
The author of this article recently presented his experiences and expertise at the IBD Convention (Industrial Brewer and Distilling). The technologies developed by Talbot & Talbot had been successfully applied to breweries over the size of 500,000 hectoliters/annum in Africa and abroad.
