SWT Green Efficiency

We continually reduce resource usage and step-by-step achieve improved efficiency of processes.

By realizing the measures concerning energy efficiency including the furnaces, more than 100 million kWh have been saved already.

SWT Green Processes

We continually improve our energy efficiency according to DIN EN ISO 50001 in all business processes. This reduces CO2 emissions and saves precious resources.

Our principles:

By modernising and technically optimising our burner technologies at our electric arc furnace, we achieved a reduction contribution of more than 1,200 tonnes of CO2 per year. Furthermore, we are optimising our tundish fires and are planning speed-controlled operation of our dedusting fans in the steel plant for 2024.

Optimised circular

We reprocess our metallurgical by-products for subsequent utilization paths. We close global material cycles in the long run, thus making our contribution to reduce global consumption of natural resources. Currently, our electric arc furnace slag, is mainly used in road and industrial area construction and further areas of application are being explored. Separation iron obtained from slag, are crushed and fed into the steel production process. Mill scale is used as iron oxide carrier in the cement and automobile industries. From our filter dust, zinc is recovered by our partner companies. The worn-out brickwork of our stoves is recycled at the end of its useful life and made into new bricks.

Optimization green space management

Handelsblatt calculated that a single tree (beech or maple, e.g.) binds about 1.5-2.5 tonnes of CO2 throughout its life. We plant shrubs and trees on the company premises. Since 2020, 200 shrubs have been planted around the scrap yard. We also plant trees outside the company together with regional cooperation partners. In 2021, we planted about 2,000 seedlings, for example. They will bind about 4,000 tonnes of CO2 throughout their life cycle.
