Slash Piles Don't Just Slow Down the Job. They're Next Season's Wildfire.
No Grinding. No Hauling. No Obstacles.
Eliminate wood waste
Our air curtain burners are a cost-efficient, environmentally-friendly solution to eliminate unwanted wood and vegetative waste 40x faster than an open burn.
Low operating cost
Reduces hauling, grinding, and tipping fees. Available for Purchase or Rental. Ideal for short-term projects or long-term waste management solutions.
return carbon to soil
Our self-contained air curtain burners turn wood and vegetative waste into soil amending ash and Biochar.
What It Actually Costs to Deal With Slash
To eliminate 100 tons of woody debris, here's what the math looks like, based on Air Burners' published cost analysis using the FireBox S330.
What the experts have to say
Trusted by the People Who Fight Fire
"The CharBoss is effective at reducing slash piles without as much smoke and particulates as would be seen from open slash pile burning. It keeps the understory green longer in the growing season so it's less susceptible to fire. With open burning, there's no carbon captured — it just goes off into the atmosphere. It's also a waste of a valuable material. "
— Debbie Page-Dumroese Senior Research Scientist, USDA Forest Service Rocky Mountain Research Station
"It surrounds the fire in a curtain of forced air. That makes the fire burn incredibly hot and incredibly efficient, and coats all of the burning material in a layer of ash. The biochar is eventually used to help improve soil quality and water retention — critical in areas where wildfire got so hot it essentially sterilized the soil. "
— Jonas Parker District Hydrologist & Soil Scientist, Bureau of Land Management
"This equipment fills that gap and allows us to monetize slash. If we can make it from the slash that is already causing a wildfire risk, we'd be solving more than one problem. We need to reconnect the natural biochar cycle that fire suppression has interrupted — and that's what's offered by this machine. "

Slash In. Healthy Soil Out.
Every other slash disposal method removes material from the forest and leaves nothing behind. Air Burners converts it into something the forest actually needs.
Ash and Biochar
3–5% of the original weight of material is processed into soil-amending ash. Spread directly at the log landing or skid trail to restore soil structure and support forest regeneration. No secondary disposal. No hauling. What was a fire hazard becomes a soil resource.
Biochar
The CharBoss automatically converts slash into biochar — a stable, carbon-sequestering soil amendment that rebuilds fire-sterilized soils and supports long-term forest health. Jim Archuleta, a retired US Forest Service soil scientist, put it simply: biochar reconnects the natural nutrient cycle that fire suppression has interrupted. Sell it as a commodity or return it to the land — either way, the slash pile becomes an asset rather than a liability.

FREQUENTLY ASKED QUESTIONS
How does the Air Burners approach compare to open pile burning?
Air Burners machines burn 40× faster than open piles, reduce smoke by up to 98%, and produce soil-amending ash and biochar rather than a extended burn scar. Open burning is increasingly restricted or banned in regulated air quality districts — Air Burners machines are tested by the US EPA and meet US EPA 40CFR60 requirements, allowing operations to continue on no-burn days in many jurisdictions where open burning is prohibited.
Can Air Burners operate on no burn days?
In many regulated areas, yes. All Air Burners machines are tested and proven by the US EPA and meet US EPA 40CFR60 requirements — reducing smoke particulates by 98% compared to open burning. Many air quality districts permit Air Burners machines where open pile burning is prohibited. Regulations vary by state and district — contact our team to confirm what’s permitted in your area.
Can the BurnBoss reach remote logging roads and forest sites?
Yes — this is what it was designed for. The BurnBoss is trailer-mounted and tows behind a standard heavy-duty pickup truck. It can be pulled up logging roads, dropped at a landing, and moved as the operation progresses. No external power, no permanent setup, no hauling debris out. The machine goes to the slash — not the other way around.
What does it cost to eliminate slash compared to hauling it out?
Based on Air Burners’ published cost analysis, eliminating 100 tons of slash with the FireBox S330 costs $267 total — including fuel and labor. Grinding and hauling the same 100 tons to a landfill costs $5,780. In remote forest settings, hauling costs are often significantly higher than average due to access and distance.

Is the ash and biochar safe to spread in the forest?
Yes. Biochar and clean ash are natural soil components — the same materials fire has returned to forest soils for thousands of years. Research by the USDA Forest Service confirms that biochar improves soil structure, water retention, and microbial activity — particularly in areas where high-intensity wildfire has sterilized the soil. Jim Archuleta, a retired US Forest Service soil scientist, describes it as reconnecting the natural nutrient cycle that fire suppression has interrupted.
