A zero waste solution
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).

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.
