Castle Cement granted permit for waste-fuelled kiln

Castle Cement has been granted a Pollution Prevention and Control (PPC) permit for a new kiln that will use a range of waste-derived fuels at its Padeswood works.

After three years of public consultation, the Environment Agency said the new kiln at its site near Mold in North Wales “would not have an unacceptable impact on human health or cause significant pollution”.


”Alternative fuels are now considered to be the best option for cement processes and this kiln has been designed to use such fuels. “
– Danny Coulston, Castle Cement

The development will involve the investment of 60 million by Castle Cement, which has been producing cement at the site for 50 years.

The kiln is to eventually replace three other kilns at the site, and will use fuels known as Cemfuel and Profuel at the new kiln, as well as waste tyres and traditional fuels. Cemfuel is made from wastes including solvents, paints, carbon absorbers and waste oils. Profuel is derived from paper, plastics, fibre and textile wastes.

Releases
The Environment Agency said the PPC permit meant the company must “prevent or minimise” releases of polluting substances into the environment. Odour and noise must also be kept to a minimum, and raw materials used efficiently.

Steve Moore, the Agency's northern area manager, said: “After careful consideration, we have come to the view that the proposals are technically sound, use the best available techniques and meet all relevant European standards.”

The Environment Agency will monitor the new kiln with “regular visits”, it said, using a “risk-based approach”.

Reduction
Commenting on their PPC approval, Castle Cement said now the permit was in place, the company would concentre on getting the new kiln up and running in 2005. The company said the new kiln would “significant reduction” in emissions and dust.

Danny Coulston, general manager at the Padeswood works, said: “It is recognised that alternative fuels are now considered to be the best option for cement processes and this kiln has been designed to use such fuels.”
