The European cement industry has steadily increased its use of alternative fuels (a sevenfold increase since 1990) to over 7 million tonnes in 2010. Together with energy recovery, the fuel ashes are entirely used as raw material in cement production. To increase use of alternative fuels, access to waste and biomass must also increase. …
