The development of new alternative fuel (AF) processing and handling technology has enabled cement producers to improve their fuel substitution rates while providing municipal and other authorities with a sustainable, zero-waste option in the disposal of municipal solid wastes (MSWs). By Dirk Lechtenberg, MVW Lechtenberg, Germany.

In the early days of alternative fuel (AF) use in the cement industry, well-defined, mainly industrial wastes were collected separately and processed for futher separation, shredding and grinding into a “fluffy” material with grain sizes <20mm. These materials would be pneumatically fed into the kiln burners of rotary kilns.
