SUSTAINABILITY REPORT | 2013 31 By-product management Qatalum’s production process generates several by-products that cannot be reused directly in production. in 201,3 Qatalum began selling its carbon and iron byproduct to a neighbor company that produces steel. treatment and disposal of the carbon material sold in 2013 would have cost QAR 10 million and generated more emissions through transporting the materials. instead, Qatalum earned in excess of QAR 1 million for the sale of these process by-products. the diagram below shows where carbon and iron by-products are produced and how they are used by the neighbor company in their steel production process.
