Qatar Steel’s operation is based on a central principle that by-products should be reused where possible. Extra steps have been taken to be faithful to this. For example, one of the major byproducts by volume is the slag formed during the steelmaking process. Qatar Steel produces around 10% of 2.5 million tons of slag annually. This slag byproduct is reused as an alternative to clinker in roadfill. This concept will be initiated after completing research with Ashghal and the Ministry of Environment.
Qatar Steel’s production successfully reuses some of the scrap as an input in the production process. Additionally,scrap is collected from local markets. Both the internally recycled and the externally purchased scrap is used in the steel making process. The goal is to reduce the overall volume of scrap generated as an output as well as to increase the use of local scrap as an input. This directly contributes to Qatar’s initiatives to reduce material going to landfills, and chemical leaching into groundwater.

Residue waste is inevitably generated during the production process; however, by recycling this residue, Qatar Steel can reduce both raw material expenditures and volumes going to the landfill. Qatar Steel also works with other industries to find sustainable end uses for waste, as part of wider synergy initiatives.
The preventative maintenance program and policies have resulted in zero oil or chemical spills over the past six years. Qatar Steel takes pride in this achievement and makes every effort to maintain this record. Chemical waste is neutralized by adding caustic soda and processing it at the MIC waste treatment facility. Qatar Steel’s commitment to waste management amounted to about QAR 10 million over the past 5 years. Further to this, the total investment in environmental management measures over the same period has reached more than QAR 47 million.
