See what our customers say about the Maine Kiln and our service

★★★★★

"The Maine Kiln transformed our waste management completely. We went from paying $12,000 annually for disposal to generating $8,000 in biochar revenue. ROI in 18 months - couldn't be happier."

Sarah Mitchell

Operations Manager, Heritage Orchards


★★★★★

"We looked at four different biochar systems. The Maine Kiln was the only one we could tow with our existing fleet. The American craftsmanship shows - it's built like a tank and runs flawlessly."

James Kowalski

Facilities Director, Willow Creek Farms

★★★★★

"I was skeptical about the one-person operation claim, but it's absolutely true. My 62 year old father runs it solo without any issues. The enclosed design also made permitting surprisingly easy."

New Inquiry

  • What types of feedstock can the Maine Kiln process?

    The Maine Kiln processes wood waste, agricultural residues (corn stalks, straw, nut shells), animal bedding, cannabis/hemp waste, root balls, construction debris, paper products, cardboard, and more. Feedstock should be relatively dry for optimal processing.

  • Do I need special permits to operate?

    The enclosed firebox design with minimal emissions significantly reduces permit requirements compared to open burning. Check with your local fire department, but many operators find permits easier to obtain than traditional waste burning methods.

  • How long does a batch take?

    Processing time varies by feedstock moisture and density, but typical batches process in 3-6 hours. The system is designed for continuous operation with multiple barrels rotating through the process.

  • What's the typical ROI timeframe?

    Most operators achieve ROI in under 2 years through a combination of eliminated disposal costs and biochar sales revenue. Exact timeframe depends on your waste volume and local biochar market prices.

  • What training is provided?

    The Maine Kiln is delivered road-ready with comprehensive operating instructions. The system is designed to be intuitive - employees can be trained quickly. Additional support is available as needed.

  • What maintenance is required?

    Minimal routine maintenance is required. Replacement parts and maintenance service plans are available. The rugged construction means years of reliable operation with basic care.

  • Can I qualify for carbon credits?

    Yes! Biochar production sequesters carbon in stable form for hundreds of years, making it eligible for carbon credits. We can provide assistance with life cycle analysis and credit quantification.

  • What trailer size should I choose?

    The 16-foot trailer (16 barrels) is our most popular configuration, offering excellent capacity while remaining highly maneuverable. Choose based on your waste volume and site accessibility needs.
