Our Mission

Turning Maui’s Biomass Challenge into Long-Term Island Value

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.

Strengthen Maui’s Circular Economy

Convert local biomass into useful local products instead of treating it as waste.

Support Healthier Soils

Produce biochar products that can improve soil structure, water retention, nutrient management, and compost performance.

Reduce Land & Landfill Pressure

Create a productive outlet for woody green waste, agricultural residues, and invasive species biomass.

Advance Durable Carbon Removal

Pursue measurable, standards-based carbon storage where technically and economically defensible.

Why Now

A Local Carbon Platform Built for Maui’s Current Needs

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.

Waste Pressure

Woody biomass, green waste, and agricultural residues need productive local outlets that reduce landfill dependence and create value from material already generated on island.

Wildfire Resilience

Invasive and overgrown biomass can be converted into useful carbon products, supporting fuel-load reduction while avoiding open decomposition or unmanaged disposal.

Soil & Water

Biochar can support water retention, nutrient management, and soil resilience across farms, resort landscapes, restoration projects, and compost-blended products.

Financeable Scale

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.

Mauiʼs Challenges

Built Around Real Maui Problems

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 woody biomass and green waste
Waste & Landfill

Tens of Thousands of Tons of Organic Material Each Year

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.

Commercial green-waste disposal on Maui currently carries meaningful tipping fees.

Water & Reef

Nutrient Retention for Healthier Soils and Watersheds

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.

Biochar can support nutrient retention and soil-water management.

Future Applications

Future Environmental Feedstock Potential

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.

Future optionality — not part of the initial operating plan.
Sources & diligence note: Public claims are based on County of Maui solid-waste materials, current Maui green-waste fee information, Maui Nui Marine Resource Council limu monitoring, USDA biochar guidance, and EPA/ITRC PFAS treatment guidance. All project-specific figures remain subject to final engineering, feedstock agreements, permits, and lender diligence.
The Solution

Biochar is the Answer

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.

The Pyrolysis Process

Carbon Without Combustion

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.

Frequently Asked Questions

What Lenders, Reviewers & Partners Ask

Answers to the most common questions from financing sources, grant reviewers, community members, and commercial partners.

What is biochar?
Biochar is a stable, carbon-rich material produced by heating woody biomass in a low-oxygen environment (pyrolysis). When properly produced and applied, biochar can support soil health, water retention, nutrient management, and long-term carbon storage.
What feedstocks will Maui BioCarbon use?
Kiawe, black wattle, agricultural green waste, landscaping debris, and pineapple byproducts. Supplier LOIs are in place. Feedstock is expected to come from agricultural operations, landscaping, and invasive-species removal — not forestland conversion.
Is this incineration?
No. Pyrolysis heats biomass in the absence of oxygen — there is no combustion. The result is a stable carbon-rich material rather than ash. Emissions performance depends on system design, operating conditions, and emissions controls.
What products will the facility sell?
Bulk agricultural biochar, compost-blended amendments, environmental media, landscaping products, and potentially carbon removal credits subject to MRV qualification. Feedstock diversion fees may provide additional revenue from intake where commercially appropriate.
Who will buy the biochar?
LOIs are in place with BrightView, Mahi Pono, Maui Gold, Fairmont Kea Lani, Mākena, and Kapalua. Target customers include farms, resort landscaping, composting companies, county programs, botanical gardens, and environmental projects.
How does this reduce landfill burden?
By converting suitable woody biomass and green waste into biochar, the facility can create an additional productive local pathway for material that would otherwise require disposal, composting, mulching, or other handling routes. Commercial green-waste disposal on Maui currently carries meaningful tipping fees, making productive diversion economically relevant for some generators and haulers.
How does biochar help Mauiʼs reefs?
Biocharʼs high porosity and nutrient-retention properties can help soils retain water and nutrients when applied appropriately. As part of broader soil-management practices, this may reduce nutrient losses from leaching and runoff.
Can pyrolysis address certain contaminated organic materials?
High-temperature thermal treatment may have future applications for certain contaminated organic feedstocks, including biosolids. Maui BioCarbon’s initial project is focused on woody biomass, green waste, and agricultural residues; any PFAS-related application would require permitting, feedstock qualification, technology validation, emissions controls, and regulatory approval.
Which carbon registries will Maui BioCarbon use?
Maui BioCarbon intends to pursue certification through Puro.earth and/or Carbonfuture — two leading registries for biochar carbon removal. Both require rigorous MRV and third-party verification. Credit revenue is treated as upside, not in base projections.
Where will the facility be located?
Maui BioCarbon is pursuing a site at Pulehunui Industrial Park, a commercial and light-industrial zone in central Maui, well-positioned for biomass logistics and distribution across the island.
What permits are required?
State, county, environmental, and operating permits. The permitting pathway is under active development through regulatory consultation, engineering review, and project-specific operating requirements.
