Our Mission

To create high-performance renewable products that immediately replace fossil fuels and eliminate their negative impact on the environment.

What We Do

Aymium produces high-value biocarbon and biohydrogen products that can be used to immediately replace fossil fuels in the production of metals, energy and crops and in the purification of water and air with no modifications to equipment or processes. Aymium’s innovations are backed by more than 250 issued and pending patents on a global basis. Produced using sustainably sourced, PEFC-certified biomass, including recovered and unusable wood, Aymium’s biocarbon products are renewable, carbon-negative and they replace emission-heavy fossil fuels such as coal and coke.

Aymium produces its products using a combustion-free thermochemical process that separates the components of biomass into biocarbon, biohydrogen and water. The process creates excess energy and water that is recycled back into the system.

Headquartered in Minnesota, Aymium currently operates the largest advanced biocarbon facility in the world, located in Michigan. Aymium has been supplying customers globally from its Michigan plant since 2012. To meet growing demand, Aymium is building two additional plants on the West Coast that will employ more than 120 people and be operational in 2023. The projected CO2 reduction from these two plants is the equivalent of removing 312,000 cars from the road each year.

We are advancing our growth pursuant to our Sustainable Development Policy, which actively promotes environmental and social improvement.
