Qatarization PortalWaste Management and Recycling
A comprehensive procedure has been developed for identification, segregation, collection, and disposal of waste generated within our operations. A summary of all waste shipments for non-hazardous wastes is reported to and MoECC – Qatar each quarter. Hazardous waste is stored at an approved hazardous waste storage facility and shall be disposed locally by the third parties within the coverage of disposal contract. Qatar Steel has studied and implemented various options to reuse / recycle the production waste. Palletizing of EF dust, recycling of refractory bricks and extracting iron from EAF Slag are many examples of our salient achievements.

The Facilities Department has undertaken various initiatives in the non-hazardous waste management segment. For many years, unsegregated waste generated in the company used to be sent to the landfill. In order to reduce the resulting negative environmental impact, we started segregating waste from the source point of generation and diverted the recyclable waste to recyclers. Colour codes of blue, yellow, green, brown and black have been provided for containers meant for collecting wood, plastic, domestic, general and paper wastes respectively. The steel skips and plastic bins which are properly colour coded and labelled, are placed in different parts of plant and office areas to collect wastes in a segregated manner.
In 2021, 1,073 metric tons of non-hazardous waste was collected and disposed as detailed in the following table:
