What Birchtech Corp. does
In the company’s own words
Birchtech Corp. (trading under the ticker symbol on the American LLC exchange) operates as a specialty activated carbon technology company focused on air and water purification solutions. The company maintains its corporate website at www.birchtech.com and serves as a provider of patented and proprietary technologies for mercury emissions capture and water treatment applications.
The company's primary business segment centers on mercury emissions control for coal-fired power plants across North America. Birchtech delivers mercury capture solutions through its proprietary two-part SEA® process, which achieves mercury emissions removal at lower costs and with reduced operational impact compared to alternative methods. The technology is specifically designed to meet EPA Mercury and Air Toxics Standards (MATS) requirements while preserving power plant output and maintaining the marketability of byproducts. As of December 31, 2025, sixteen electric generating units in the United States utilize the company's SEA® technologies.
The company has recently expanded into water treatment, launching a new business segment in April 2024 to address the growing potable water market. This division focuses on next-generation sorbent technologies designed to remove forever chemicals, particularly PFAS compounds, while using significantly less activated carbon than traditional approaches. Birchtech has invested in two state-of-the-art Design Centers located in Pennsylvania and North Dakota, which serve as innovation hubs for water treatment development and offer thermal reactivation, contaminant analysis, and carbon performance evaluation services.
The company's intellectual property portfolio includes eighteen granted patents worldwide relating to mercury removal, consisting of thirteen U.S. patents and five foreign patents. Additionally, Birchtech has filed provisional and PCT patent applications for its water treatment technologies. The company maintains a license for proprietary intellectual property related to boiler treatment and emissions reduction at power plants.
As of December 31, 2025, Birchtech employed fourteen full-time and six part-time employees. The company operates manufacturing and distribution facilities from its principal location in Corsicana, Texas, which has served as the operational hub since 2015. The company was originally incorporated in Utah in 1983 and redomesticated as a Delaware corporation in 2007, subsequently rebranding from Midwest Energy Emissions Corp. to Birchtech Corp. in October 2024.
