What is biochar?
Biochar is a stable form of carbon produced from biomass through pyrolysis, used to improve soil health and sequester carbon.
How does the Big Box kiln work?
The Big Box kiln operates by heating biomass in a low-oxygen environment, allowing for the production of biochar.
What safety measures should be taken when using the kiln?
Ensure a charged hose is available for fire control and construct a fire line around the kiln to prevent fire escape.
What types of feedstock can be used?
Any woody species can be used, preferably small and dry materials for starting the kiln.
Can the kiln be used in wet conditions?
Yes, but starting the kiln may require dry material to ensure ignition.
What are the benefits of using biochar?
Biochar improves soil fertility, enhances water retention, and helps sequester carbon in the environment.
