Aberthaw Works submits alternative fuels proposal

UK: Plans to burn used tyres and plastics for energy at Lafarge's Aberthaw works in South Wales have been submitted to the Environment Agency for approval. Lafarge's comes after it sent out 5000 letters to residents explaining the latest proposals and held two public consultations. The proposal has previously sparked concerns among some residents and environmentalists.

The plant's management team says that the move would cut costs and reduce coal burning and CO₂ emissions. The proposal comes six years after the Lafarge meat and bone meal (MBM) from cows and sheep as a sustainable waste-derived fuel at the plant. If the move is approved by the Environment Agency, the used Solid Recovered Fuel (SRF), including papers and plastics, and end-of-life car and van tyres, could save up to 15,500t/yr of coal and reduce carbon dioxide emissions by up to 20,000t/yr.

James Kirkpatrick, manager at the Aberthaw works, which has an integrated capacity of 0.55Mt/yr, said the plan had been prompted by increased competition in the cement market and a serious downturn in demand for construction products. "Since it was introduced in 2005, we have used 50,000t of MBM which has significantly reduced our consumption of fossil fuels," he said. "Extending the range of sustainable waste-derived fuels we can use offers us a good way to keep a check on our costs which have been escalating."

Keith Stockdale, secretary of Barry and Vale Friends of the Earth, said, "The Environment Agency will have to impose strict conditions on the burning of this potentially hazardous waste."
