Sign InBacTech Environmental Corporation (CSE:BAC) has filed national patent applications for its Zero Tailings™ technology in Canada and the United States on April 14, 2026. This follows the company's original international (PCT) patent application filed on April 7, 2025. The proprietary bioleaching technology converts sulphide and iron mining tailings into marketable products such as fertilizer and critical minerals. The process aims to achieve zero waste output from traditional mining operations. This move represents the company's effort to protect and commercialize a breakthrough process in industrial waste management. The development is viewed as a positive step for the company with potential long-term implications for the global mining sector. However, the immediate market impact remains limited at this stage.
