We turn hard-to-handle biomass into clean on-site energy and biochar—restoring soils while locking away carbon

Powering the healing of the planet

Residue Streams Disrupted

Wet biomass accumulates quickly and becomes costly to handle. Left unmanaged, it drives emissions and locks operations into expensive, carbon-intensive energy.

Our Mission

Regenerative agriculture, powered by residues

Poás Bioenergy builds carbon-negative systems that convert wet agricultural residues into clean process heat and biochar—helping producers reduce handling costs, cut emissions, and return carbon to soils for long-term storage.

See How We Do It

Agriculture should run in a loop, not a line

In a healthy system, residues become on-site energy and biochar returns value to soils. But when residues are discarded and energy is bought separately, costs rise and emissions stack—season after season.

2 RETURN CARBON TO SOIL

Biochar that supports healthier farms

Biochar is a stable form of carbon that can improve soil structure, water retention, and nutrient cycling. We produce biochar as a core output—so value returns to the farm instead of leaving the system.

1 CLEAN UP RESIDUE STREAMS

Turn messy biomass into a managed input

Wet residues build up fast and are costly to move, store, and control. We help sites stabilize residue handling by converting these streams into a consistent, usable feedstock for on-site conversion.

3 DECARBONIZE PROCESS HEAT

Reliable energy from what you already have

Instead of purchasing carbon-intensive fuels, our systems convert residues into syngas for process heat (and optional power). That means steadier operations, lower exposure to fuel volatility, and a cleaner production footprint.

Our solution

We have developed a new gasification technology that takes in the inconvenient biomass and produces high energy density syngas and biochar. The syngas can be used for heat energy or run through a generator to provide cheap, reliable, clean energy.

The biochar can be added to crop soil where it works as both a carbon sequestration technology and a fertilizer amendment that improves the health and production of crops.
