Alternative Fuels

There are a number of sustainable and offer considerable benefits to the CEMEX approach, including reduced emissions and energy costs, saving valuable fossil fuels for the future and recovering energy from waste, thereby reducing the need for landfill. By cutting the burning of coal and petcoke, alternative fuels also help to reduce emissions of carbon dioxide. In doing so, they reduce climate change.   While CEMEX plants operate well within their emission limits, experience shows that performance improves further when using alternative fuels. Cement kilns operate at temperatures at which steel would melt. That, combined with the length of time which fuels spend in the kiln, means that the process releases their energy while completely and safely consuming them.

Alternative fuels have been successfully used in cement kilns for decades. In the UK, alternative fuels used include secondary liquid fuels, scrap tyres, paper, packaging and household waste, meat and bone meal and sewage sludge pellets.
