Land Clearing Debris Removal Without the Hauling Bills.
Eliminate Wood Waste, Brush, and Vegetative Debris On Site.
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.
Air Curtain Burners for Land Clearing Debris
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 Experts Are Saying
Trusted By People Who Fight Fire
"Valley Environmental uses an Air Curtain Burner for the environmentally friendly disposal of wood and vegetative waste. The advanced technology of the machine produces a highly clean burn at a fraction of the economic and environmental cost. It is the most environmentally friendly alternative to all other green waste processing methods."
— Ryan Ramage Founder, Valley Environmental LLC — Land Clearing & Organic Waste Management
"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."
— Jim Archuleta Retired Soil Scientist, USDA Forest Service — Co-Creator of the CharBoss
"The curtain burners are very good at burning slash and brushy-type material, allowing the reduction of fuels on homeowners' properties and increasing forest resiliency."
— Brian York Battalion Chief, Cal FireWhat's Left Behind
Clean Ground, Ash, and Biochar
Every other method leaves something behind that still needs dealing with. Grinders leave chips. Open burning leaves burn scars. Hauling leaves an empty yard and a full invoice. Air Burners leaves clean ground, and something that actually improves the site.
Clean Ash
100 tons of woody debris becomes 3–5 tons of soil-amending ash and biochar. Spread it directly on the cleared site to restore soil structure, support revegetation, and accelerate ground recovery. No secondary disposal. No hauling. The site is cleaner and the soil is better than before the job started.
BioChar
The CharBoss converts woody debris directly into biochar — a stable, carbon-sequestering soil amendment that rebuilds fire-sterilized soils and supports long-term forest health.
Jim Archuleta, a retired U.S. 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
Can an Air Burner handle whole trees, stumps, and root balls?
Yes. Air Burners FireBoxes are designed to accept whole logs, root balls, stumps, slash piles, brush, and green waste, without any pre-processing, chipping, or size reduction. The larger FireBox Series (200 and 300 Series) handle the highest volumes continuously, while the BurnBoss is ideal for more remote or off-road access situations.
How does operating cost compare to a grinder?
Dramatically lower. An industrial grinder costs $900+ per hour to operate and still leaves 98 tons of chips per 100 tons of input — all of which may need to be hauled.
An Air Burners FireBox runs on fewer than 3 gallons of diesel per hour, eliminates waste completely on-site, and leaves only 2–3 tons of clean ash. There are no tipping fees, no hauling runs, and no separate equipment passes.
How long does it take to clear an acre?
It’s the first question every project manager asks — and the answer is that it depends on two things: how many trees are on the property and how large they are.
The Boss Series processes 5–10 cubic yards of typical forest slash per hour, handling material up to 8″ in diameter. The larger FireBox Series scales up significantly — processing up to 100 cubic yards of woody debris per hour in optimal conditions. A lightly wooded acre with smaller diameter material can be cleared in a single day. Dense timber with large root balls will take longer — but with no waiting for the material to dry, no hauling runs breaking up the workflow, the machine keeps moving as fast as the loader can feed it.
Contact our team with the acreage, tree density, and average material size and we’ll give you a realistic throughput estimate.
Are Air Burners compliant with air quality regulations on job sites?
It is always important to check with your fire marshal to understand the rules around using an air curtain burner. All Air Burners machines are tested by the US EPA and are designed to meet the requirements of US EPA 40CFR60.
They reduce smoke particulates by up to 98% compared to open burning. Many air quality districts permit Air Burners machines when open pile burning is prohibited. Regulations vary by state and district — our team can advise on your specific location’s requirements.
Is the ash safe and what do I do with it?
The ash and biochar left behind are natural soil amendments — this can be spread on-site to improve soil structure and pH, eliminating disposal entirely. Alternatively, it can be collected and screened for sale or disposal.
Either way, what was 100 tons of debris becomes 3-5+ tons of ash and biochar — a fraction of the original volume and a fraction of the disposal challenge.
