Mobile Biochar Systems
Our Biochar Story
In 2019,founder Kevin Bernard set out to solve a growing problem, mountains of cannabis biomass destined for the dumpster every day. His search for a sustainable solution led him to biochar and the realization the cannabis industry needed help to be sustainable, smarter and mobile.
The first experiments were rough: a makeshift kiln welded together from a recycled oil tank and two used barrels. But failure sparked innovation. Branding a new business, Local Biochar, Kevin built a four barrel prototype, proving that biochar technology didn't have to be tied to one site-it could move to where the waste is.
After two years of testing, redesigning and refining, the concept evolved into the Maine Kiln, a rugged, second generation system engineered for efficiency and reliability. Alongside key partners who mentored scaling efforts, we fine-tuned performance and burn quality, pushing the mobile biochar technology forward.
In 2025, we rebranded the corporation to Mobile Biochar Systems to express exactly what we do: design and fabricate mobile biochar kilns that bring biochar production to your site. No transporting waste, no waiting for clean up and no wasted energy.
Today, our systems are in the field, delivering real results-and scaling fast, because the future waste management solution isn't stationary. Its mobile.
PROUDLY MADE IN THE USA
American Craftsmanship and Innovation You Can Trust
Every Maine Kiln is fabricated in Westbrook, Maine by a family-operated business with high-end metalworking expertise since 1952. Built with locally sourced materials to exacting standards.
We are committed to continuously developing new designs, reactor vessels, renewable fuel sources and material handling techniques to enhance the performance and efficiency of our systems.

Decades of expertise paired with a steadfast commitment to sustainability
Kevin is Experienced in sales and marketing, engineering, real estate, and sustainable technology. He began his professional career as an electronics engineer with a startup CD manufacturing company as part of a design team responsible for early innovations in compact disc manufacturing technology. He joined Dux Computers in 1992, a startup clone computer company. There, he gained hands-on experience building and repairing computers, as well as designing, installing, and troubleshooting office network systems, until the company ultimately ceased operations.
Transitioning into real estate, Kevin spent more than 20 years as a successful investment real estate broker, specializing in sales and marketing for investors and contractors. Building on this experience, Kevin founded a real estate development company focused on rehabilitating multi-unit residential properties, alongside a property management company to oversee renting of units. Over time, he assembled a portfolio of 16 apartment buildings, managing complex financing structures and coordinating multiple concurrent construction and redevelopment projects for each asset.
In 2019, Kevin founded Cannawaste recycling, which transitioned from cannabis waste to a manufacturer of biochar kilns.
A startup veteran with 15+ years of executive leadership, specializing in scaling operations that blend efficiency with measurable impact.

At Community Wellness, Kris led initiatives in remote patient monitoring to strengthen chronic care management and healthcare partnerships. Previously, at HotChalk and EAB, he drove client success and long-term growth across dozens of universities.
Today, Kris extends his expertise to sustainability as a board member at Mobile Biochar Systems, helping guide a company that is redefining organic waste management with mobile biochar technology. Passionate about innovation, scalability, and building enduring relationships, Kris is committed to solutions that deliver lasting change across industries.
Peterson started his career as a CPA for the American Broadcasting Company (NY, LA and SF) for 11 years and then as CFO for publisher HarperCollins SF.
Peterson then immersed himself for 30 years in Silicon Valley working for numerous tech startups. He also co-founded three startups that were successfully sold. They included Sentrytrack, a remote monitoring solution for municipalities; webKPI, winner of a QuickBooks "Awesome Add-On" Award; and WasteTrakr Technologies Inc., focused on cannabis waste. Steve then orchestrated the sale of WasteTrakr for its investors to the public company GCAC for shares.
In 2016, Peterson was hired at one of San Jose’s largest dispensaries as General Manager for Elemental Wellness and then ran two dispensaries in Oregon for investors. The Oregon properties were sold to Harborside in Oakland, CA as part of a public reverse merger. Peterson then worked with Tress Capital, an early investor in technology for the cannabis industry, where he led a newly formed group called Tress Solutions.
As a thought leader, he wrote two e-books on #salescomp and accounting services moving to the cloud.
Peterson currently heads up Business Development activities for the public company GCAC “Global Compliance Applications Corp” (CSE:APP). The company leverages the power of blockchain to create new applications including Efixii track and trace, clearESG for brands to share sustainability efforts, and Efixii Uplift for NFT discount coupons. In 2024, GCAC acquired a streaming TV network, rebranded it as “CitizenGreenTV,” and launched on Apple TV, Android, Roku, Amazon Fire TV, and over the web. The network features over 450 shows, including artists such as Montel Williams. Steve is excited to connect his broadcasting career experience with the power of blockchain to engage a new generation of viewers and consumers.

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."
"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."
"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."

Frequently Asked Questions
For us, customer support means being more than a vendor – we’re your partner, connector and educator. We share knowledge openly and support your success to help strengthen the entire biochar industry.
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.
