An assessment on the recycling opportunities of wastes emanating from scrap metal processing in Mauritius

• Scrap metal processing wastes.
• Areas of applications for slag, electric arc furnace dust, mill scale and wastewater sludge.
• Waste generation factor of 349.3 kg per ton of steel produced.
• Waste management model.

This paper presents an assessment on the wastes namely slag, dust, mill scale and sludge resulting from scrap metal processing. The aim of this study is to demonstrate that there are various ways via which scrap metal processing wastes can be reused or recycled in other applications instead of simply diverting them to the landfill. These wastes are briefly described and an overview on the different areas of applications is presented. Based on the results obtained, the waste generation factor developed was 349.3 kg per ton of steel produced and it was reported that slag represents 72% of the total wastes emanating from the iron and steel industry in Mauritius. Finally the suitability of the different treatment and valorisation options in the context of Mauritius is examined.
