Closing the loop with side-stream materials
In 2018, 155,400 tonnes or 83 percent of all side-stream and waste materials leaving the production processes were sold as products, sent for external use or reclaimed internally.
0.25 (0.6) percent of the process residual materials were sent to safe destruction or landfill as hazardous waste (classified according to local waste regulation in respective country of operation).

Destinations of process waste and process side-stream materials
It takes knowledge, creativeness and co-operation to find use for the different materials.Two of our most useful REACH registered product developments are Petrit® E and Petrit® T, which are both made of slag. Petrit E can be used to replace gravel in road construction, fillers in asphalt, construction materials and raw material for the production of stone wool. Petrit T functions as a lime replacement and can for example serve as lime additive for structure liming in clay soils, which improves the quality of the soil for agriculture.
Melting furnace dust is sent for zinc recovery and other forms of dust are processed for iron recovery. Filter materials can find use as a slag former in metal production.
Non-process related waste amounts to 5,100 tonnes, or to less than 3 percent of the sum of all waste and side-streams.
