FOCUS ON MATERIALS
A Fissler pan . average ,” said the materials specialist .
“ To produce Circle Green , we have reviewed and optimised the emissions from each production step from the stainless-steel melt process and energy production to transport and raw material production . Green energy plays a significant role , along with the use of special raw materials , such as organic coke for ferro-chrome production and optimised scrap management . Circle Green is not a new grade . Rather , it is a philosophy that enables the carbon footprint of existing grades to be minimised . This means that our customers like Fissler can adopt Circle Green without having to worry about approvals , because its exactly the same – only even greener ,” it continued .
Austenitic stainless steel
impact on manufacturing or performance in use , we had complete confidence that it would work . And they were right . It sailed through our battery of tests on how easy it was to produce , how it reacted to contact with food and how well it cooked . In fact , it did so well that we used what remained of the test material in production . Some lucky customers already have pressure cookers made from Circle Green ,” he outlined .
“ There is still a lot more that we would like to explore with Circle Green , such as how we handle the scrap from our production . While the scrap is , of course , recycled it is then mixed in with our general stainless-steel scrap . It would be good to find a way to segregate it and return it to Outokumpu to maintain the Circle Green loop ,” he added .
The next level for sustainable cookware
Sven Ullrich concluded : “ The drive for sustainability requires strong partnerships throughout our supply chain . We have relied on Outokumpu ’ s stainless steel for decades . Now , with its Circle Green , we are taking Fissler ’ s sustainable cookware to the next level .” n

Circle Green is already available in several grades . The grade used by Fissler is a classic 18 % chromium / 8 % nickel austenitic stainlesssteel . This is an all-purpose material with good corrosion resistance and is suitable for a wide variety of applications that require good formability and weldability . It is also nonmagnetic .
The stainless steel is supplied as cold-rolled coils . Fissler then stamps it into flat discs ready for deep drawing to create pots . Currently , Fissler is planning to use Circle Green in a limited number of “ hero ” products . It will then look at extending its use in the future .
A key aim for producing Circle Green is to ensure that it behaves in the same way as the stainless steel that it is substituting . Responsibility for the test programme to verify the suitability of the material fell to Mark Distelrath , Head of Global Purchasing & Supply Chain Management , Fissler .
“ We have relied on Outokumpu ’ s stainless steel for generations . So , when its experts told us we could adopt Circle Green with no
