BacTech Environmental Files National Patents for Zero TailingsTM Technology in Canada and United States BacTech Environmental Corporation announced the national patent filings of its proprietary Zero TailingsTM technology in both Canada and the United States. The filings, made April 14, 2026, follow the company's original international (PCT) patent application filed on April 7, 2025, and represent a major step in commercializing a process that the company believes will fundamentally change how the global mining industry manages waste. BacTech's Zero TailingsTM process is designed to eliminate this liability entirely. Zero TailingsTM combines BacTech's proven bioleaching technology with existing downstream processing technologies to put every element present in a tailing into solution -- and then recover each element as a saleable product. Applied to sulphide and iron tailings, the process produces four principal product streams: Magnetite - high-purity iron oxide supplied to the steel and pigment industries; Ammonium Sulphate Fertilizer a nitrogen-and-sulphur fertilizer suitable for broad agricultural markets; Critical Minerals recovered in elemental form to supply clean-energy and advanced-manufacturing supply chains; and Silica -- industrial-grade silicon dioxide for construction, electronics, and specialty chemical applications. Because the process is designed to extract a product from every element present in the tailing, there is no residual waste stream -- hence the name Zero TailingsTM. BacTech's Zero TailingsTM process produces ammonium sulphate a dual-nutrient fertilizer providing both nitrogen and sulphur -as a direct by-product of treating sulphide and iron tailings. Unlike conventional fertilizer production, which relies on natural gas feedstocks and long international supply chains, BacTech's ammonium sulphate is generated through a biological process applied to existing mining waste stockpiles. The result is a domestically producible, sustainably derived fertilizer that can be manufactured in Canada and the United States -- independent of the geopolitical supply disruptions currently driving global food security concerns. Ammonium sulphate produced through BacTech's bioleaching process is a biologically derived fertilizer, generated by naturally occurring bacteria rather than through energy-intensive conventional synthesis. This positions the product favourably with the growing segment of agricultural buyers and food producers seeking sustainable, traceable inputs -- and potentially opens pathways for premium pricing in specialty and certified sustainable markets. Canada and the United States represent two of the world's most significant mining jurisdictions, collectively hosting thousands of active and legacy tailings facilities. Both countries have enacted, or are advancing, regulatory frameworks that increase the financial burden on mine operators associated with tailings storage and long-term environmental monitoring. BacTech believes that Zero TailingsTM addresses these regulatory pressures directly by offering operators a path to full materials recovery and site remediation. The national filings also position BacTech ahead of growing investor and regulatory demand for ESG-compliant mining practices. With critical mineral security a priority for both governments, a process that recovers those minerals from existing waste streams -- rather than requiring new primary extraction -- aligns directly with federal supply-chain strategies on both sides of the border. Patent Timeline: April 7, 2025 -- Original international (PCT) patent application filed for Zero TailingsTM. April 14, 2026 -- National phase filings submitted in Canada and the United States.
