South West Water owner Pennon's subsidiary Viridor Waste Management is to build a new plant to generate energy from waste in Devon.The 'Energy from Waste' (EfW) plant, to be built at Marsh Barton in Exeter, will process 60,000 tonnes of municipal waste a year and will require Viridor to stump up £45.6m in capital investment. The agreement was reached with Devon County Council.Pennon says the agreement comes as the European Landfill Directive encourages alternatives to landfill."The Exeter project, the latest EfW development for Viridor, is part of its long term strategic partnership with Devon County Council designed to assist Devon in achieving its landfill diversion targets," said Viridor chief executive Colin Drummond. "The new plant will have an electrical power generation capacity of around 3MW and will come on stream by 2014."---RG
