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.
The Numbers Don't Lie
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
"We can reduce our tree waste by 95% in mass from wood to ash. The ash from this process is then added to our top soils as an enrichment to the soil. Nothing is wasted. The enrichment does three things — it holds moisture longer, it saves water, it holds the nutrients we apply for a longer period of time, and it breaks down into natural nitrogen which is good for the topsoil. We're working to always be as efficient as we can — that's our goal."
— Rick Wohfiel PAW Materials Inc.
"Air Burners is the best thing that ever happened to our company as far as what we do. In anything in life, everybody's looking for an edge — a way to get the most out of everything. We were burning 25 gallons an hour on the first grind and 35 gallons an hour on the second grind. Now I burn a gallon and a half an hour tops with the Air Burner. Air Burners burn clean. Neighbors don't even know it's burning. I haven't had any complaints."
— Tighe Scott President & Founder, Scott Farms, Inc.
"We're not just burying trash and moving on — we're looking at ways that we can change the way things work. The Air Burner takes waste that was previously left to rot in the landfill, burns it, captures the heat, and turns it into electrical energy that goes back to the grid. That process will produce a top quality compost that people can utilize any way they feel free. You're going to see waste become a commodity — utilized in different ways, and a much better way than just putting it into the ground."
— Chuck Magee Retired Public Works Manager, Kern County
"It's virtually a smokeless burning unit once the fire is started and the only thing we add to it is air. It will reduce debris down to 2% of what we put in it. It's bio-friendly. It will create what is called biochar — used out west and in the Midwest for crops and landscapers. This burner is going to reduce our debris in Hampstead and in the surrounding areas."
— Haywood Bryant Owner, Branch and Brush Debris
"ArborWorks cares about slowing the pace of climate change. That is why we are using curtain burners to remove dead wood. The unique air curtain technology traps black carbon emissions, preventing them from entering the atmosphere. When it comes to managing large amounts of organic waste material, air curtain burners are a game changer."

Waste In. Value Out.
Every other disposal method turns green waste into a cost. Air Burners turns it into something useful.
Ash and Biochar
The ash and biochar left after burning are natural soil components, rich in carbon, potassium, and calcium. Spread directly on-site, donated to local farms, or collected and sold as a soil amendment. What was 100 tons of woody waste becomes 2 tons of clean, usable material. The CharBoss goes further, producing marketable biochar at scale with a growing commodity value.

Energy
With the Power Series paired to any FireBox, the heat generated during elimination is captured and converted to electricity — on-grid through the PGFireBox, or stored off-grid in the BioCharger’s Battery Storage Module. The waste that used to cost money to dispose of now generates power to run the operation. That’s a fundamental shift in how green waste facilities think about their cost structure.

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.
