Viridor Ltd (from the Latin 'to become green') is a recycling, renewable energy and waste management company in the United Kingdom, owned by KKR (previously owned by Pennon Group). The company was formed in 1956 as Harrison Western Ltd, later becoming Haul Waste Ltd. Haul Waste became part of Pennon (then South West Water Ltd) in 1993, and grew by purchasing companies in the waste collection and landfill disposal market. In 1995 it bought Blue Circle Waste Management, bringing about South West Water's name change to Pennon Group in 1998, and the merger of Haul Waste and Blue Circle Waste Management under Viridor. It subsequently acquired part of Churngold's waste business in June 2003, Thames Waste Management in 2004, Somerset LAWDC Wyvern Waste in 2006, Grosvenor Waste Management and Skipaway Holdings in 2007, and Shore Recycling in 2008. Later in 2015 Viridor took over the collection side of Dorset based waste company Commercial Recycling. More information...
