BIRCHTECH CORP.

What BIRCHTECH CORP. does

Birchtech Corp. (NYSE American: BCHT; formerly Midwest Energy Emissions Corp., then ME2C Environmental) is a publicly traded specialty activated carbon technology company that develops and supplies environmental media and systems for air and water purification. Its core technology is the patented SEA® sorbent for mercury emissions capture at coal-fired utilities, which has served 40% of the U.S. coal-fired fleet under EPA's Mercury and Air Toxics Standards (MATS) since 2011. The company's IP portfolio spans 35+ patents, which were validated through a seven-year patent enforcement effort culminating in a final judgment of approximately $78.4 million from the U.S. District Court of Delaware and the permanent termination of all IPR challenges.

Birchtech's product portfolio is organized into Clean Air (SEA® sorbent) and Clean Water (SEA-IX™ nuclear-grade ion exchange resins, granular activated carbon, catalytic carbon, mixed media, RSSCT pilot testing, rjGAC™ carbon rejuvenation, and a PFAS Field Pilot Program). The company operates Design Centers in Grand Forks, ND (analytical/RSSCT) and State College, PA (carbon rejuvenation), with manufacturing in Corsicana, TX and corporate headquarters in Houston, TX. Revenue is generated through licensing agreements, product supply (sorbents and ion exchange resins), turnkey water treatment system sales, and pilot testing/consulting services, with enterprise sales targeting coal-fired utilities, municipal water systems, nuclear power plants, and industrial operators primarily across the United States and Canada.

The go-to-market is direct enterprise sales backed by technical specialists, supported by industry-conference presence (AWWA, ASMS, state water associations), investor-facing conferences, technical content marketing, and a recently added partner channel with Civil & Environmental Consultants Inc. (CEC) for RSSCT delivery across 34 U.S. offices. Pricing is contract-based and not publicly disclosed; revenue mix is lumpy due to one-time licensing/settlement payments layered on top of recurring media supply and services.
