Outokumpu supplies “Circle Green” stainless steel, through Stahl Krebs, for Zwilling knives to continuously reduce the CO2 footprint of major Zwilling knife series. The steel used in knives accounts for more than two-thirds of the knives’ total product carbon footprint. Now in the first phase, Circle Green will be used in the premium line Zwilling Pro, one of the high selling knife series of Zwilling, reducing its carbon footprint by approximately one third*. Going forward, Zwilling intends to convert more knife series step by step to Circle Green. For Zwilling, this is a significant step towards the decarbonization goal defined as part of the company’s sustainability strategy.

First martensitic “Circle Green” stainless steel for high-quality knives

The “Circle Green” product line with up to 93% lower carbon footprint than the industry average** is the first commercial towards-zero stainless steel in the market. It was created to accelerate the green transition and extremely advance circular economy. To achieve such a low level of emissions, Outokumpu uses 100% low-carbon electricity, low-carbon raw materials, such as recycled steel, and reinvented production processes, such as electric arc furnaces. This means that Circle Green stainless steel has the same mechanical properties and the same high quality and durability as the previously used material.

“Our spearhead climate solution, ‘Circle Green’, has the lowest carbon footprint in the world. If all the stainless steel in the world was produced with the same methods used for our ‘Circle Green’ production, it would reduce global carbon emissions from the entire stainless steel value chain by 364 million tons per year – there is a true opportunity to transform various industries. With ‘Circle Green Dura’, we are providing Zwilling the first CO2 reduced martensitic stainless steel grade that is designed for applications that demand a high level of surface hardness, high strength and wear resistance. With this collaboration we are proud to continue our decarbonization journey and support our customers in their climate targets,” states Thomas Anstots, President, business line Advanced Materials at Outokumpu.

Zwilling towards carbon neutral product portfolio

“We are very pleased that these two partners, Outokumpu and Stahl Krebs, will support us on setting pathway for improving our Scope 3 emissions. As one of the oldest brands in the world, our ambition has always been to offer kitchen products that combine quality and durability with a sense of responsibility for people and the environment,” explains Alexander Gulden, Chief Technology Officer and Member of the Board of Management at Zwilling.

“For us, it is crucial that we can offer products that are as sustainable as possible and, if feasible, at the same price level as before. This allows consumers to purchase our climate-friendly range of knives and make an important contribution to the environment,” says Gernot Strehl, Head of Product Compliance and Material Technology and Project Leader for this collaboration at Zwilling.

The future-oriented steel trading company Stahl Krebs was the initiator of this project and operates as a steel intermediary within this collaboration. “We are pleased to be part of this important partnership and to be able to contribute to the climate-friendly production of high-quality knife products with our expertise and know-how in the steel trading sector,” affirms Daniel Krebs, managing director at Stahl Krebs.

* On average per knife, compared to same knife series with previously used steel.

** For the “Circle Green” classic grades: global average CO2 emissions (2023): 7 kilos of CO2e per kg of stainless steel (Outokumpu’s calculation based on data provided by CRU and worldstainless). Outokumpu “Circle Green” CO2 emissions: down to 0.5 kilos of CO2e per kg of stainless steel. For Outokumpu “Dura” grade, such a global comparison is not available, but “Circle Green” Dura’s carbon footprint is 50% compared to standard Outokumpu “Dura” production.
