House construction has great potential to protect the climate as the construction and building sector causes 38% of global CO2 emissions putting the choice of materials in focus. Werl Germany based steel profile maker Gebhardt-Stahl expert has relied thyssenkrupp Materials Processing Europe for supply of, CO2e reduced slit strips. The bluemint recycled starting material from thyssenkrupp Steel Europe is of particular importance in this project. Due to modified input materials, the product can show a reduction in CO2e emissions of over 60%. In addition, the steel is characterized by a high recycled content. The reduced value of the starting material's CO2 emissions as a result of the more environmentally friendly production is incorporated in the model for calculating the Product Carbon Footprint at thyssenkrupp Materials Processing Europe, which is unique on the market to date. The PCF calculator calculates the exact CO2e emissions for each product from production to delivery. For each article, it is thus possible to transparently show all steps from production to delivery, storage and processing to delivery to the customer in terms of greenhouse gas impact. This means that all data along the entire supply chain to the customer, the so-called cradle to gate approach, is taken into account. The sophisticated calculation logic of the PCF calculator has been certified by the international classification society DNV and is being used for the first time in the delivery to Gebhardt-Stahl.Gebhardt Stahl is a manufacturer of profiles and supplies accessories for air conditioning and ventilation technology, reinforcing profiles for window and door systems, fence posts and vineyard posts as well as a wide range of special profiles as a construction material for numerous applications.
