See it in action
Built for the field. Designed for results.
The Ring of Fire Kiln® converts waste wood and brush into biochar — a soil amendment that stores carbon, restores forests, and improves land for generations. Six mild steel sheets bolt together in minutes, with an outer heat shield that pulls smoke back into the kiln for a cleaner, safer burn.
No heavy machinery. No open burn piles. 5.6 cubic yards of capacity, assembled by two people in 15 minutes, anywhere in the field.
“I am extremely pleased with my Ring of Fire Kiln. I love the way it pulls back the flames and sparks back into the kiln and generates no smoke.”
What you’re getting
Built for anyone who works with land
“Having a Ring of Fire kiln has been awesome for us! We have been using the kiln to turn the large volume of slash left after each timber harvest into char instead of just burning slash piles. What a generative thing to do with a forestry mess!”
“The kiln works great for our smoke reduction needs. And we used all the char on the 1 acre farm we have.”
From setup to biochar
Love Earth. Make Biochar.
Frequently asked questions
What makes the Ring of Fire unique?+
Its dual-ring design — an inner pyrolysis ring and outer heat shield — enables fast, clean, safer biochar production compared to open burn piles. Smoke is pulled back into the kiln for a cleaner burn and significantly reduced air quality impact.
Who typically buys and uses the Ring of Fire?+
Small woodland owners, forestry contractors, and environmental groups committed to wildfire fuel load reduction and forest restoration. Farms with woody debris also use it to produce biochar for composting and soil improvement.
How easy is it to assemble and operate?+
Two people can assemble it by hand in approximately 15 minutes — no heavy machinery needed. Simply load biomass, light, and tend. A full burn produces 2–3 cubic yards of biochar in 4–5 hours.
How does it help the environment?+
By converting biomass to biochar with 10–20% efficiency, it significantly reduces smoke emissions, stores carbon in the soil long-term, and helps restore forest ecosystems and improve air quality.
Are there financial benefits?+
Yes — biochar can be sold as a premium soil amendment, used to enhance crop yields, or applied in environmental remediation. Low operational costs make it cost-effective for producers at scale.
“Since receiving our Ring of Fire kiln, we’ve been integrating biochar production into many different aspects of our land management goals. We’re very grateful to have this simple, effective tool at our fingertips.”
“The kiln is working very well. We have had 7 successful burn days so far this season. We have been using the biochar in the horse stalls and under the chicken tractor, and then it goes into our compost piles for a few months.”
“This Ring of Fire is gorgeous. So happy with the kiln. Turns out the neighbor has a pile that will last the rest of my life — I just have to go a mile and a half up the road to get it.”
