The green shift

Cinis will produce the world’s most environmentally friendly mineral fertilizer, potassium sulphate (SOP). Relying on a circular approach and by recycling industrial waste salts and ash from the pulp & paper industry we bring a unique product to the market.

Recycling of industiral salts and ash from black liquor boilers – Production of a high value mineral fertilizer (potassium sulfate) and salt (NaCl) with a "close to zero" carbon footprint.


We need to stop wasting resources, increase the circular approach in production and decarbonize the fertilizer industry. Today, ash and salts with a high degree of valuable chemicals are lost to our seas and rivers.

Todays production of SOP relies heavily on the use of crude oil not only due to the high energy demand. To produce the sulfuric acid needed an estimated amount of 280 million barrels of oil need to be desulfurized in order to create all the acid that is consumed by the process.


Using our patented process we turn waste salts and ash into sulphate of potash (SOP) - a high value mineral fertilizer with a local and global market.

Relying on a circular acpproach and utilizing fossil fuel free energy we create a high quality product with a "close to zero" carbon footprint.

Todays production of SOP (K2SO4)

Sixty percent (4,2 million ton per year) of todays market of the fertilizer SOP is produced through the “Mannheim process”.
This is an old process where sulfuric aid is mixed with KCl in a reaction at 600-700 C using fossil fuels.

Besides potassium sulfate also hydrochloric acid (HCl) is produced which limits the use of the Mannheim process.

Replacing the Mannheim process with the "CINIS process" for production of SOP will reduce global CO2 emmission by: 1 Million ton CO2 per year.
