Biochar’s Big, Carbon-Rich Moment?

Experts and advocates say it’s time to address the soil amendment’s limitations so that its potential as an agricultural climate solution can be realized.

On the day the Tigercat carbonator — a machine that looks like a giant metal dumpster mounted on Snowcat-style treads — arrived in western Montana from Oregon, Michael Schaedel set to work navigating “a colossus” over narrow, rolling forest roads.

As a forester with The Nature Conservancy, Schaedel works to thin and restore 500,000 acres of former industrial timberland to make it more resistant to wildfires. And he collects debris and burns it in piles so that it doesn’t become fuel for future fires. It’s a common practice, but it releases carbon dioxide into the atmosphere. So he and others are looking to the carbonator —which burns the material in a way that traps carbon and creates a product called biochar —instead.

After two weeks of trying it out, he was impressed with the results. His team was burning debris that would fill 60 to 80 dump trucks daily with little to no smoke. But the second half of their plan is bound to be more difficult. Schaedel’s team hopes to convince western Montana farmers to take the biochar and add it to their soils…
