About
Preterra BioCarbon Solutions Ltd. is a Salt Spring Island, BC-based biochar producer founded in 2022 that uses German SP-SC pyrolysis retort technology to convert BC wood waste (sawmill residues, forest thinning slash) into high-carbon biochar. The biochar is sold as a soil amendment (including via Amazon.ca) and is being developed as a concrete admixture for long-term carbon storage in building materials.
