When municipal solid waste is co-processed in a cement kiln, the solid waste is screened and disposed of directly or used as a RDF. Abad et al. measured PCDD/F emissions from cement kilns co-processing meat and bone meal and waste tires in Spain and found that co-processing the solid waste contributed little to PCDD/F emissions (Abad et al., 2004).
