With the help of Darren McAvoy, assistant professor at , we’re making biochar to improve our soil health and move toward a more sustainable way of farming. Biochar is charcoal made specifically for the soil and is created by burning organic waste in a low-oxygen environment. Darren built this kiln to do exactly that, at scale. That controlled burn locks carbon into a stable, porous material instead of releasing it into the atmosphere. When inoculated, those pores become a thriving home for beneficial microbes. It holds water and nutrients in the soil longer, reduces the need for inputs, and keeps carbon locked in the ground for centuries, making it one of the only truly carbon negative practices in agriculture.
