Cinis Fertilizer has signed an agreement with Swedish environmental company Ragn-Sells to handle and upcycle sodium sulphate that arises as a residual product from industrial processes.

The sodium sulphate Ragn-Sells will deliver comes from industrial clients who generate this as a residual stream in their production. This cooperation marks a step forward in the company’s efforts to increase the proportion of byproduct streams used in its production and to expand the supplier base for its facility in Köpmanholmen, Örnsköldsvik.

“This agreement is not only an important milestone in our efforts to increase the use of byproduct streams in our production, but also a testament to our ability to solve a real problem for the industries that generate sodium sulphate as a byproduct,” said Jakob Liedberg, founder and CEO of Cinis Fertilizer. “Additionally, the fact that we are compensated for receiving and processing the sodium sulphate underscores the value of our circular business model.”.

Through the agreement, Cinis Fertilizer will upcycle sodium sulphate, a byproduct of industrial production, into potassium sulphate – a high-quality mineral fertilizer. This circular solution makes it possible for industrial clients to upgrade landfill residues into recycled material and the sodium sulphate, which is otherwise primarily seen as a waste problem, instead becomes a valuable input and a contribution to enabling more sustainable agriculture.

The first test delivery of sodium sulphate from Ragn-Sells was carried out in August and continuous deliveries are now starting immediately.
