Sinter plants are sink for solid wastes generated in a steel plant. All the dusts generated in the sinter plant are recycled back, and thus no solid waste or hazardous waste is generated. Wastewater is generated mostly in sinter plants where multi-cyclone are used for cleaning process gas (Li et al. 2019b).
