Abstract


Globally foundries are the backbone of the manufacturing industry and are strategically important for job creation. South African environmental laws classify foundries as significant source of air pollution and requires every foundry installation to comply with rigorous licensing conditions. The formulation of the emission standards stems back to period where the main melting technology was based on cupola melting, using coal as source of energy. Today the majority of foundries use induction furnaces with electricity as main energy source. It is possible that current emissions guidelines are outdated and require revision. The purpose of this study is to determine and analyse the emission generated by local ferrous foundries in terms of SOx, NOx and particulate matter. Experimental results obtained are compared with secondary data from international studies. Recommendations on the sector’s preferred approaches to emission regulation are formulated for the attention of the Department of Environmental Affairs.
