German rebar distribution and bending group Sülzle Stahlpartner has introduced a carbon-reduced product line named STOOX PCF Steel, validated by auditing organisation TÜV.
According to a company spokesman, the move follows increasing inquiries from construction projects, especially in the public sector. Stoox will already be used in an ongoing project, the construction of the U5 underground train line in Hamburg, to which Sülzle is delivering pre-fabricated, custom-made reinforcement cages.
Sülzle claims that Stoox has an average carbon footprint of less than 400kg CO2 equivalent per tonne, undercutting the original target of 500kg CO2e/tonne, as is requested by the awarding authority.
Sülzle appears to be the first German distributor of rebar to announce such a label. It became a member of the Responsible Steel movement one year ago. “We are certainly the first company to have the entire process for determining the product carbon footprint backed by a TÜV certification,” the spokesman tells Kallanish.
Sülzle receives its rebar from various mills that document the carbon footprint of their production; the TÜV certificate also covers the subsequent logistics and fabrication, the spokesman explains.
Hamburg’s ARGE U5 project, a joint venture between Ed. Züblin AG and Wayss & Freytag Ingenieurbau AG, is meant to be a lighthouse project for environmentally sound construction. It aims to reduce conventional CO2 emissions during the U5 construction by 70%.
