German BENTELER Steel Tube’s Managing Director Mr Christian Wiethüchter last month announced plans to become CO2 neutral by 2045. He said "To achieve this goal, we initiated our ‘green tubes’ program in 2020, which focuses on reducing the CO2 footprint in tube production. Procurement and production play strategic roles in this but our product portfolio also underlines our sustainable focus. This is demonstrated, for example, by our new BENTELER HYRESIST line pipes for hydrogen, which support the development of hydrogen distribution networks."The green tubes program is specifically concerned with the avoidance of CO2 emissions. Where this is not possible, the company tries to reduce or compensate. The metal processing specialist’s Steel & Tube division plans to halve its total CO2 emissions by 2030 and become CO2-neutral by 2045. To achieve this goal, BENTELER Steel & Tube aims toAchieve CO2 neutrality by 2030 for direct emissions (Scope 1) generated in production Indirect emissions (Scope 2) generated through the purchase of energy y 2030Emissions on the procurement side (Scope 3) will be reduced by 30% in the first step. By 2045, BENTELER Steel/Tube also wants to become CO2-neutral on the procurement side and thus have greened the supply chain, production and products. Important measures on this path are, for example, the purchase of electricity from renewable energies and the use of CO2-neutral raw materials in the manufacture of welded tubes.The electric steel mill in Lingen already produces steel exclusively from scrap, resulting in 90% fewer direct CO2 emissions than the conventional blast furnace method. In addition, BENTELER is looking into alternative raw materials for steel production that are just as CO2-neutral as recycled steel scrap. For example, a cooperation with RWE and CO2Grab has been formed to test the use of direct reduced iron produced with green hydrogen as a raw material in steel production.For the production of seamless tubes, BENTELER sources steel from its in-house electric steel mill in Lingen. Using steel produced in an electric arc furnace, 500 to 800kg of CO2 is generated per ton of tube, depending on the amount of added value and production plant. If steel produced in a conventional blast furnace was used, this figure would be at least 1,500 kg CO2 per ton higher.
