Thyssenkrupp starts commercial supply of low-carbon steels

Thyssenkrupp Steel delivered on Thursday the first batches of its climate-neutral steel, which it markets under the brand name “Bluemint”, Kallanish hears from the company. The first customer to be supplied with flat steel products of the Bluemint family is German bathroom builder Kaldewei.

Through the use of hot-briquetted iron, the company claims to have reduced its emission intensity per tonne of steel by 1.5 tonnes to 0.6t of CO2, an overall reduction of 70%. The emissions of the so-called upstream chain – Scope 3, meaning emissions that occur during the production and transportation of the raw materials – are retained.

Tk underlines that the approach has been independently assured by international certification body DNV, as well as by the Wuppertal Institute for Climate, Environment and Energy, the company’s advisor to the project.

“The methodology for calculating product-related CO2 savings is in accordance with the internationally recognised Greenhouse Gas Protocol for Product Life Cycle Accounting and Reporting Standard,” confirms Priti Hoffmann, sustainability lead, Benelux at DNV.

The launch of the Bluemint product family also means the start of active marketing measures for products with an allocated low CO2 intensity. Following the contract with Kaldewei, “we will gradually expand the commercialisation of Bluemint, and have already commenced negotiations with a number of additional customers,” tk Steel chief executive Bernhard Osburg.
