Maui BioCarbon is developing a 30–35 ton-per-day biochar facility at Pulehunui Industrial Park to convert locally sourced woody biomass and green waste into high-value biochar products for agriculture, land management, environmental use, and carbon removal.
Our mission is to help Maui transform organic waste into long-term ecological and economic value.
Maui BioCarbon exists to create a local pathway for woody biomass, green waste, and invasive species residues that would otherwise be landfilled, burned, chipped, or left to accumulate.
By converting those materials into biochar, we aim to support healthier soils, more resilient landscapes, local agriculture, landfill diversion, and measurable carbon storage.
We are building this project for Maui — not as an abstract carbon project, but as practical local infrastructure that connects waste management, agriculture, land stewardship, and climate resilience.
Convert local biomass into useful local products instead of treating it as waste.
Produce biochar products that can improve soil structure, water retention, nutrient management, and compost performance.
Create a productive outlet for woody green waste, agricultural residues, and invasive species biomass.
Pursue measurable, standards-based carbon storage where technically and economically defensible.
Maui BioCarbon is designed around immediate island constraints: limited disposal capacity, high organic-waste handling costs, wildfire-fuel reduction needs, and growing demand for resilient soils and local circular-economy infrastructure.
Woody biomass, green waste, and agricultural residues need productive local outlets that reduce landfill dependence and create value from material already generated on island.
Invasive and overgrown biomass can be converted into useful carbon products, supporting fuel-load reduction while avoiding open decomposition or unmanaged disposal.
Biochar can support water retention, nutrient management, and soil resilience across farms, resort landscapes, restoration projects, and compost-blended products.
A 30–35 TPD initial facility creates a practical first commercial platform: large enough to matter, small enough to finance, permit, and operate with discipline.
The project is built around immediate Maui waste, soil, and water challenges, while preserving optionality for future environmental applications as the technology, permits, and markets are validated.

Maui continues to manage a significant stream of green waste, woody biomass, biosolids, and other organic material. Much of this material has historically required landfill, composting, mulching, or other disposal pathways. Maui BioCarbon is focused on creating an additional local outlet for suitable woody biomass and green waste.

Local monitoring has identified nitrogen enrichment at some Maui coastal sites, with fertilizer and wastewater among the potential nutrient sources. Biochar can help soils retain nutrients and water, reducing nutrient losses from leaching when applied appropriately as part of a broader soil-management strategy.

Research and regulatory attention are increasing around thermal treatment of certain contaminated organic materials, including biosolids. High-temperature thermal systems may have future applications in this area, but only with appropriate permitting, feedstock qualification, technology validation, emissions controls, and regulatory approval. Maui BioCarbon’s initial project remains focused on locally sourced woody biomass, green waste, and agricultural residues.
Maui BioCarbon converts green waste into biochar — a stable form of carbon that enriches soil, reduces erosion, and provides long-term environmental benefits.

Micro-sponge effect: When properly produced and applied, biochar can support soil water and nutrient retention, improving soil health and reducing irrigation demand.
Root and microbial health: Biochar improves root health, microbial life, and turf resilience across agricultural and landscaping applications.
Durable carbon storage: Biochar can provide long-term carbon storage when produced, characterized, and documented under recognized standards.
Low-emission process: Pyrolysis generates both biochar and syngas for self-powered energy recovery, while reducing wildfire risk through invasive species removal.
Circular economy: Every ton of waste processed generates value — for farmers, for the islandʼs carbon balance, and for Mauiʼs waste infrastructure.
Pyrolysis heats organic waste in a low-oxygen environment so it does not burn. The result is a stable carbon-rich material, with emissions performance dependent on system design, operating conditions, and controls.

Biomass heated to ~400–700℃ in an oxygen-limited chamber. Organic material thermally decomposes — no burning, no incineration.
Biochar (solid carbon) is the primary product. Syngas is captured and reused to provide renewable process heat, reducing external energy demand.
Syngas is reused within the process to reduce external energy purchases, improve operating resilience, and support a more efficient thermal system. Enclosed process with emissions controls throughout.
Feedstock is generated from agricultural operations and invasive species removal activities — not associated with conversion of forestland. Supplier LOIs are in place.
Fast-growing, frequently cut back, high-carbon-density woody biomass — a strong pyrolysis feedstock with limited or negative economic value in current disposal markets.
Fast-growing invasive contributing to wildfire risk. Biomass conversion creates a productive removal pathway that reduces fuel load and ecological impact.
Crop residues, orchard trimmings, and farm biomass including pineapple agricultural byproducts from Maui Gold and other diversified farm operations.
Commercial and resort landscaping material from Mauiʼs hospitality sector, diverted from landfill through partner relationships including BrightView.
Carefully sourced woody material from invasive species management programs. Not associated with conversion of native habitat or forestland.
Letters of intent in place with local feedstock suppliers across agricultural operators, landscapers, county programs, and land managers.
A diversified set of revenue streams creates income and offsets costs — making the project resilient across market conditions.
| Revenue Stream | Role in Model | Notes |
|---|---|---|
| Biochar Product Sales | Primary Revenue | Bulk and blended biochar products for agriculture, landscaping, environmental, and soil-improvement applications. |
| Feedstock Diversion Fees | Feedstock Monetization | Potential intake revenue from providing a productive local pathway for woody biomass, green waste, and agricultural residues. |
| Renewable Energy Recovery | Operating Cost Offset | Syngas recovery can reduce external energy purchases and improve operating resilience, subject to final system design. |
| Carbon Removal Credits | Potential Upside | Pursued only where registry qualification, MRV requirements, and economics support issuance; not assumed in base-case projections. |

Direct sales to farms, ranches, and agricultural operations for soil amendment, water retention, and crop productivity improvements across Maui.
Value-added blended products for retail, landscape, and agricultural markets. Higher-margin with broad commercial appeal and established distribution channels.
Biochar for stormwater filtration, nutrient retention, erosion control, and environmental applications across Mauiʼs infrastructure.
Landfill daily cover, odor control, leachate management. Potential for direct offtake with Maui county waste management operations.
Retail and commercial products for resort properties, botanical gardens, residential markets, and Mauiʼs growing green infrastructure sector.
When produced, characterized, and documented under recognized standards, biochar can support long-term carbon storage. Pursued where technically and economically defensible.
Maui BioCarbon intends to pursue carbon removal credit certification through Puro.earth and/or Carbonfuture — two of the leading registries for biochar carbon removal. Credit qualification requires rigorous MRV of biochar production, characterization, and application. Carbon credit revenue is treated as upside and not included in base financial projections.
