Biochar
As Minnesota’s leader in nature-based climate solutions through land restoration, Great River Greening is at the forefront of expanding the practice of burning waste materials in biochar kilns as part of natural management.
Biochar is a type of charcoal produced by heating organic material in a high-temperature, low-oxygen environment. Sometimes described as “supercharged charcoal,” biochar is part of a traditional farming practice that has received increasing attention in recent years for its use in land restoration and carbon sequestration
What is biochar?
When restoring landscapes, often the first step is removing invasive species. This results in large quantities of wood waste product such as invasive buckthorn and other brush. The common practice of burning waste in an open pile burn releases greenhouse gases, creates air pollution, and damages the soil where burning takes place.
There is an alternative that restores degraded land, mitigates climate change, improves soil and water quality, AND makes better use of the waste left behind after invasive species removal: biochar.
Benefits of biochar
This “supercharged charcoal” bolsters conservation efforts in many ways:
It’s a low-tech option to provide a powerful, nature-based climate solution.
Producing biochar sequesters and stores carbon. In a kiln, up to 80% of the greenhouse gases that would have been emitted in an open pile burn are stored, and less smoke is produced.
The soil underneath the kiln is protected from the otherwise scorching heat of the fire.
Putting biochar back on the land improves soil health by retaining nutrients and water.
Working with Great River Greening
