Birchtech Corp.

Birchtech Corp. is an environmental technology company dedicated to advancing solutions for air and water purification. Headquartered in Corsicana, Texas, with additional operational and R&D facilities, the company's mission is to provide effective, affordable, and sustainable technologies for utilities and critical infrastructure, ensuring cleaner air and water.

The company specializes in activated carbon technologies, with its core business centered on patented Sorbent Enhancement Additive (SEA®) technologies for mercury emissions capture in the coal-fired utility sector. Birchtech is also expanding significantly into water purification, developing disruptive solutions for contaminant removal, particularly per- and polyfluoroalkyl substances (PFAS and PFOS), through smart carbon management, turnkey water treatment services, and advanced testing capabilities via its Design Centers.

Led by President and CEO Richard MacPherson, who founded the company in 2008, Birchtech Corp. recently uplisted its common stock to the NYSE American (trading began February 26, 2026) and completed a $15 million capital raise to fuel the expansion of its water treatment business. The company also secured a $78 million federal court judgment in a patent infringement case in December 2025, underscoring the strength of its intellectual property. Birchtech is actively commercializing its water treatment solutions, securing initial purchase orders and pursuing strategic partnerships to scale its operations and market positioning.
