Promises from Prime Minister Gordon Brown to build more housing should create a huge increase in demand for recycled building and land generation materials said Viridor Waste Management. Browns proposals for up to 160,000 environmentally friendly homes to be built on brownfield sites was welcomed by the company, which specialises in recovery and recycling of construction and green wastes, and land remediation. External affairs manager Dan Cooke said: Gordon Brown's initiative is an unmissable boost to the market for a whole range of recycled materials from secondary aggregates for use on site roads during construction to compost use to create attractive amenity and leisure open spaces. We already produce hundreds of thousands of tonnes of these each year. With the pressure on local authorities to recycle up to 60% of municipal and other wastes, this is a great opportunity to close the recycling loop. The company recovers useful materials from demolition and other waste streams at its recycling centres across the UK. New building products can be made from the waste such as chipboard made from waste wood; glass-fibre thermal insulation materials made from recycled bottles and secondary aggregates. It also regenerates brownfield sites using quality soil improvers or composts and has carried out works on the Thames Gateway and other developments.
