Castle Cement, which has a major manufacturing site near Clitheroe, UK, has become the first cement manufacturer in the UK to be given the green light to burn Meat and Bone Meal (MBM) to fire its production kilns. The decision announced by the Environment Agency on Thursday follows a six-month trial period where the company fired one of its kilns using the animal by-product.  Company general manager Gareth Price, of the company’s Ribblesdale works, said: "We are very pleased with the decision of the Environment Agency and once again we are able to safely use the energy content of a waste product to help fuel our kiln.  There are no emission problems associated with its use and it helps solve society’s waste problems by providing an effective and safe recovery of energy.
