Based in Grande-Synthe (59), the company SGA was established in May 2004 to meet the need for processing and valorisation of co-products from the ArcelorMittal steelworks in Dunkirk.
Our services consist of evacuating most of the co-products in liquid form (1,600°C) at the foot of the steelworks up to 1 million tonnes per year. These co-products are sorted by nature and quality and, after deferrisation, valued as embankments, agricultural materials and road hydraulic binder.
