Alternative Fuels

We are increasing our use of alternative fuels, such as chipped tires, household waste, and biomass such as animal meal, sewage sludge and agricultural waste. Because temperatures in cement kilns are very high, virtually all organic hazardous compounds are converted to harmless substances, meaning they are ideal for safely disposing of these kinds of waste and recovering energy in the process. Our kilns enable us to provide a suitable and necessary alternative to landfill while reducing our reliance on fossil fuels and our resulting CO2 emissions and protecting our business from energy-price volatility.


While we safely and successfully use our cement kilns to dispose of some of society's waste in locations where we have completed the necessary trials and public consultations, local residents often have concerns about the use of tires and other waste as fuel. We work with our neighbors and local interest groups to help them understand the process and the safeguards we will put in place to allay their concerns.

The extent of our use of alternative fuels depends largely on local regulations, specifically whether landfill legislation is mature and well implemented.
