Upcycle Minerals Inc. is a sustainable SOP fertilizer technology development company located in Saskatoon, Saskatchewan. Upcycle aims to become a low-cost, carbon-conscious producer of Potassium Sulfate fertilizer (SOP). It aims to use its newly developed brine to SOP production technology to produce potassium sulfate fertilizer and two valuable co-products: ammonium sulfate fertilizer (AMS 21-0-0-24), and precipitated calcium carbonate (PCC) an industrial mineral. Carbon dioxide is a required chemical input to its process, being ultimately captured into PCC.

Potassium sulfate (SOP) is a premium form of potash fertilizer containing both potassium (K) and sulfur (S) macronutrients with little to no chloride found in regular Potash (MOP). Although SOP can be used in place of Potash (MOP) it is most commonly used on high value crops like fruits, vegetables, tree nuts, etc.
