Green Steel FAQ
What is green steel?
Green Steel means steel which is particularly resource-saving in the process of production/logistics, especially regarding the use of fossil energies and CO2 emissions. By increasingly using renewable energies and reducing CO2 emissions, SWT Green Steel will get “greener” gradually.
HOW DO YOU MEASURE THE GRADE OF GREENNESS?
There are different international evaluation methods. Currently, we use two methods:
- GHG - the climate balance according to the so-called Greenhous Gas protocol issues the CO2 footprint of a company
- EPD - the Environmental Product Declaration measures the environmental compatibility of a product throughout its entire lifecycle
Is building with steel generally "greener" than building with other building materials, such as concrete?
Yes, it is. Each tonne of steel contains unlimited potential: the material can be completely recycled again and again without losing its material quality. Compared to building with concrete, building with steel has also the advantage that a lot less trucks are needed to get the material to the building site.
How muchCO2 is saved in the production of SWT Green Steel?
When producing our CO2-reduced steel, we currently achieve emissions of 335 kg CO2e / tonne of molded steel. This means that we save approx. 418 kg CO2 / t compared to conventional mold steel production in the EAF route and approx. 1,600 – 1,900 kg CO2 / t compared to the integrated blast furnace route.
PER TONNE OF SECTION STEEL
Sample Calculation:
Bauforumstahl calculated savings of 15kg CO2 emission per square meter building area. When building a warehouse with an area of 12,000 m2, SWT Stahlwerk Thüringen Green Steel saves a total of 175,260 kg of CO2.
HOW CAN SWT GREEN STEEL BE IDENTIFIED?
Customers who order SWT Green Steel receive an extended sales order confirmation. After delivery they receive a mill test certificate including data about CO2 balance and a link to our Green Steel web application. Our customers can choose if they only want to see the carbon footprint of production or additionally the emissions of the logistic process according to the incoterm – up to the warehouse destination of the customer.
