Letter of Intent with Cinis Fertilizer

K+S intends to gain access to potassium sulfate in Scandinavia

Kassel, 28.06.2022 
K+S has signed a letter of intent with the Swedish company Cinis Fertilizer on future cooperation in the synthetic production of potassium sulfate (SOP). Under the planned agreement, K+S intends to supply Cinis Fertilizer with its entire potassium chloride (MOP) requirements. In return, K+S could purchase up to 600,000 tonnes of potassium sulfate (SOP) per year from Cinis.

“The agreement fits perfectly with our new corporate strategy, which includes the expansion of our core business through cooperation,” says K+S Chairman of the Board of Executive Directors Dr. Burkhard Lohr. As a result, K+S will secure additional quantities of the specialty fertilizer potassium sulfate. K+S will therefore be in an even better position to supply its customers as well as to acquire new customers.

Sustainable production

Cinis Fertilizer is planning the synthetic production of potassium sulfate in the so-called Glaserite process at several production sites in Scandinavia. In addition to potassium chloride supplied by K+S, the company will use residues from battery, pulp, and paper production as raw material and renewable energy. Sodium chloride (salt) is also generated as a by-product in the production of potassium sulfate.

K+S and Cinis Fertilizer intend to convert the letter of intent now reached into a binding contract for both sides in the short term and thus establish a long-term business relationship.
