Environmental technologies for the future.

Birchtech develops specialty activated carbon technologies that remove contaminants from both air and water — high-performance, cost-efficient, and sustainable, guided by a data-driven, performance-based approach.

Birchtech’s patented SEA® sorbent technology has delivered cleaner air across the United States since its first commercial supply contract. Our mercury-capture sorbents have consistently exceeded federal and state requirements under the EPA’s Mercury and Air Toxics Standards (MATS). Today, Birchtech applies that same expertise to disruptive water purification technologies — targeting forever chemicals such as PFAS and PFOS, along with heavy metals and other regulated contaminants — engineered for maximum efficiency, environmental sustainability, and strong operating economics.
