UK: Lafarge Cement UK's Cauldon Works in Staffordshire has received recognition for its industry-leading sustainability achievements, which have seen it reach an alternative fuel substitution rate of 50%. The achievement is the latest milestone for the plant, which has been researching, developing and using alternative fuels, mainly processed sewage pellets (PSP) and tyre chips, for a decade.

Its parent company, Lafarge Group, has honoured the works as part of its annual awards. These champion the efforts of employees worldwide who are transforming the way in which products are manufactured. As part of the latest achievement, Lafarge has announced that the Cauldon team was able to run the calciner for a trial 10hr period using just PSP and tyre chips. Cauldon is only the third of Lafarge's 166 production sites across the world to achieve 100% alternative fuel substitution on the calciner for a limited period.

Cauldon Works' optimisation manager, Andy Woodcock, said, "We are aware that environmental legislation across the construction sector will increase in the near future and we want to be sure that we have measures in place to stay at the forefront for environmental performance and delivering sustainably-produced products to our customers. We're pleased to announce this development, which will help us continue to reduce our carbon footprint and reinforce our position as Lafarge UK's flagship works for the use of waste-derived fuels."
