Dundee Sustainable Technologies Inc. Development in Fertilizer Business

  July 14, 2014

MONTREAL, QUEBEC, July 14th, 2014 – Dundee Sustainable Technologies Inc. (“DST” or the “Corporation”) (CSE: DST), the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures, is pleased to announce its commitment in the fertilizer business.

DST has obtained patents for the production of sulfate based fertilizers. These processes are providing a new way to the industry of producing potassium sulfate (“SOP” or K2S04) and potassium magnesium sulfate (“SOPM” or K2SO4.2MgSO4). Both products are accompanied by the production of salable hydrochloric acid as a by-product.

Sulfate based fertilisers are applied at sowing time, where ions are adsorbed in the soil and remain available and protected against leaching. The growing need to do more with less, and the sulfur deficiency in particular crops have led to an increase use of sulfate based fertilisers, while excess use of chloride based fertilisers (potassium chloride or “potash”) reduces nutrient uptake and yield quantities, water soluble sulfate fertilisers such as SOP and SOPM are the most effective for growing crops.

The growing market for sulfate based fertilisers along with depleting natural sources of chloride-free potassium creates a great opportunity for DST to develop its patented processes.

DST has analyzed a project to build a plant for the production of SOP using potash and sulfuric acid. Moreover, DST has received interest from a North American distributor that is ready to market the production of 50,000 tonnes per year of SOPM and could also be interested in SOP.

Market

The current market conditions and specific demands from the fertilizer market are opening a window of opportunities to launch projects that would lead to the construction of fertilizer plants. DST’s technology allows for SOP and SOPM to be produced below current market price with profit margins preliminary estimated at $410 per tonne for SOP and $225 per tonne for SOPM.

The National Research Council of Canada granted DST a $50,000 subsidy for the assessment of its fertilizer technology.
