Creating biochar session images

We’ve lost some of our site images, but here are representative images of our process in creating biochar via pyrolysis–a form of incineration that chemically decomposes organic materials by heat in the absence of oxygen.

The process is attracting the attention of community members, soil scientists, organic gardeners, and environmental engineers, as it has been shown to be both a carbon-negative soil amendment that helps to mitigate climate change and it has the potential to dramatically increase soil fertility. These images represent our process or replicating previous community efforts; although larger-scale initiatives are underway internationally, we focus on what local gardeners and small farmers might attempt here in the Houghton and Keweenaw area.
