Waste 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 MME 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.
In this direction, 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 negative environmental impact resulting from the same, we started segregating waste from the source point of generation and diverted the recyclable waste to recyclers. Color 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 labeled, are placed in different parts of plant and office areas to collect wastes in a segregated manner. PP jumbo plastic bags, HDPE cans, packing cardboard boxes etc. constitute a considerable portion of our waste streams. As of now, 1,055 metric tons of plastic and paper wastes have been successfully given to recyclers.
