Biochar Use-Cases

Beyond Carbon Sequestration:
The Wide-Ranging Applications of Biochar

Biochar is not only a soil-amendment; it’s a game-changer. Produced by the pyrolysis of biomass, the remarkable material can elevate soil health, boost crop yields, and purify water sources, all while serving as a potent carbon sequestration tool.

Of course, biochar can and should be locally sourced from residual material, limiting transportation costs and emissions.

In addition to the probably best-known application of biochar in agriculture, there are numerous others, and they are rapidly diversifying. In many applications, biochar replaces scarce resources while improving the quality of the end-products. From its use in construction materials like concrete and asphalt to cutting-edge innovations in bioplastics, carbon-based composites, and even medical applications, the potential of biochar is enormous – and all while technology and research continue to advance and new use cases emerge.
