Stircor, a biosolid processing as a service company, creates PFAS-free biochar for sustainable use.
Stircor, a biosolid processing, drying and gasification provider, has developed and proven a process for removing Per- and polyfluoroalkyl substances (PFAS) from biosolid waste for U.S. municipalities.
The biochar, a lightweight black residue, consisting of carbon and ashes, remaining after the pyrolysis of biomas, and form of charcoal, resulting from Stircor’s proprietary drying and gasification process, was tested by a U.S. Environmental Protection Agency (EPA) accredited third party laboratory using EPA’s Method 1633.
Method 1633 includes 40 target analytes all of which were below the limit of detection.
Stircor’s biochar byproduct is PFAS-free, making it suitable for various applications, including agriculture, construction, energy, and waste treatment.
