Lafarge Cement gets green light for use of new fuels

Lafarge Cement’s Cauldon Works in Staffordshire has been given the Environment Agency’s go ahead to step up its use of the two sustainable waste derived fuels - Solid Recovered Fuel and Waste Derived Liquid Fuel.

Following a public consultation exercise and subsequent successful evaluation of the use of Solid Recovered Fuel (SRF), Lafarge has received a permit to use this fuel on a permanent basis. SRF is a material with a ‘biomass, carbonneutral’* (BMCN) component which can reduce the Works’ carbon footprint by up to 35,000 tonnes of carbon dioxide each year. Using this fuel will also enable Lafarge to reduce its use of fossil fuels by 12,500 tonnes a year - enough to provide electricity for over 8,000 homes for a year.

SRF is derived from a mixture of paper, plastic and biodegradable waste generated from homes and businesses. The material is processed through a mechanical and biological treatment plant to dry it out and produce a biomass fuel to a specification laid down by the EA.

Lafarge has also been given the green light to evaluate Waste Derived Liquid Fuel (WDLF). WDLF is a tightly specified blend of waste products with a high energy content made from materials found in every day products such as paint, solvents and degreasers. The company will be installing the appropriate equipment ready to start evaluating WDLF later this year.

Cauldon Works manager Allan Ruxton comments: “Using SRF and WDLF will help us improve our overall environmental performance, control our increasing fuel costs and help us contribute towards meeting Government targets to reduce climate change and reducing materials going to landfill. We are pleased that the EA has approved a permanent permit for SRF; and has given us agreement to progress with WDLF - also a tried and tested fuel around the world.

“The use of waste-derived fuels is an integral part of Lafarge’s drive for increased sustainability in its operations. We already have a proved track record across the world and particularly at Cauldon where we have made positive use of waste-derived materials by using them as fuels for over 15 years now.”
