Lafarge Cement’s Cauldon Works has started trialing the use of recovered fuel oil.  
 
The UK generates more than 400,000t of waste oils a year. RFO is made up of waste oils from places like high street garages and motor manufacturers.  
 
Over the last 14 years the Cauldon site has reduced its use of fossil fuels by using waste-derived materials such as chipped used tyres and processed sewage pellets. 
 
Cauldon manager Nicolas Maes said: "The site’s approach to sustainability has been particularly recognised across the worldwide  Lafarge Group
 
RFO is a proven alternative fuel, having been tried and tested for many years, particularly in the power and asphalt industries.  
 
For the cement-making process - which is extremely energy-intensive - RFO is fairly simple to introduce and is totally compatible with the other fuels we already use."  
 
The trial will last approximately six months. Once completed all data gathered during the trial will be submitted to the Environment Agency and made public..
