Lafarge is utilising waste from the disposal site of Cantagalo (Rio de Janeiro) as fuel for its cement kilns in a move that decreases the environmental liability of the disposal site and enlarge the alternative fuels blend of Lafarge.

The initiative is soon to be followed by other cement companies s Camargo Correa Cimentos, Votorantim and Cimpor.

For some years Brazilian cement manufacturers have adopted co-processing, replacing part of the fossil fuel for industrial residues. Around 35 out of the 48 cement plants in Brazil, have burned 1Mt of residues in 2008.
