K+S 
International raw materials company, K+S has over 11 000 staff worldwide, specialised in potassium salts and other minerals for use in fertilisers, animal feed, food, pharmaceutical, water treatment, de-icing and industrial applications. The roots of the K+S Group date back to the middle of the 19th century, mining the world's first potash deposits in Germany for fertiliser production. Today, K+S operates potassium and sodium mineral mines in Europe and North America and produces balanced mineral products according to customer needs. K+S is strongly focussed on agriculture and fertilisers, and makes an important contribution to society by enabling farmers to secure the world's food supply. As a raw materials company with limited resources, K+S strives to make efficient use of its own natural raw materials to counteract global scarcity, whilst ensuring responsibility towards society and the environment in operating regions. The claim is to enrich life for generations and to be a pioneer for environmentally friendly and sustainable mining. Because the extraction of valuable materials from waste streams will play an ever more important role in creating a more sustainable future, K+S has set ourselves the mission of developing new, circular business areas as part of our strategy. For this purpose, we want to actively participate in ESPP and establish partnerships to advance the circular economy. In the past, K+S successfully marketed “Thomaskali”, a secondary phosphorus product from steel industry slag. K+S will contribute to the ESPP network our many years of expertise in fertiliser production through to the targeted application of products
