In the United States (US), forest products major Weyerhaeuser Company and compatriot biocarbon producer and technology provider Aymium have announced that they have entered into a Memorandum of Understanding (MoU) to partner to produce and sell 1.5 million tonnes of sustainable biocarbon annually for use in metals production.
As an initial stage of this partnership, the companies have formed a joint venture — TerraForge Biocarbon Solutions — to build a jointly owned facility adjacent to Weyerhaeuser’s lumber mill in McComb, Pike County, Mississippi (MS), that will convert wood fiber into biocarbon through a combustion-free, low-emissions process.
Under the MoU, the companies will secure long-term biocarbon sales agreements and identify sites to construct multiple new production facilities across the Weyerhaeuser footprint over the next five years, leveraging Weyerhaeuser’s world-class timberland and manufacturing portfolio and Aymium’s proprietary technology and unparalleled track record of producing and supplying biocarbon products globally.
At full scale, the platform of operating facilities will have the potential to convert over 7 million tonnes of wood fiber — provided exclusively by Weyerhaeuser — to deliver 1.5 million tonnes of metallurgical-grade biocarbon annually as a drop-in replacement for coal in iron, steel, silicon, ferro-alloys and other metals production.
The reliability, scale of sustainable supply, and forestland expertise of Weyerhaeuser provide unmatched sourcing security of our main raw material to support expansion. Through this partnership, we will significantly grow our manufacturing capacity to produce biocarbon as an immediately scalable, renewable replacement for coal and coke, while delivering differentiated value for our customers, said James Mennell, CEO of Aymium.
Proven biocarbon technology and products
Based in Minnesota (MN), Aymium is a leader in biocarbon technology with over 600 patents and four production facilities across North America.
The company has generated a significant global sales pipeline based on years of trials with leading global metals producers.
The company’s patented products are engineered as drop-in replacements to coal and coke requiring no capital investment or process modification, and offer superior carbon levels, energy value, handling, and environmental attributes compared with coal.
Weyerhaeuser sustainably manages more than 10 million acres of high-quality timberlands across the United States as well as 33 manufacturing facilities across North America — offering unmatched scale and reliable access to fiber.
This partnership combines our renewable fiber resources and supply chain expertise with Aymium’s innovative technology and experience. It represents a major step forward in growing the scale and impact of our Climate Solutions business, and it’s also a key part of our broader accelerated growth strategy through 2030. When the McComb facility comes online in 2027, it’s going to generate new demand for fiber in the region — supporting our McComb operations and local Timberlands teams — while creating more great jobs in the community. It’s a model we look forward to replicating across our footprint, said Devin W. Stockfish, President and CEO of Weyerhaeuser.
A welcome US$100 million investment
According to the Mississippi Development Authority (MDA), the TerraForge Biocarbon Solutions project in McComb represents a corporate investment of more than US$100 million and will create 36 jobs.
TerraForge Biocarbon Solutions’ decision to locate in Magnolia marks a major win for Pike County and Mississippi. The company’s substantial investment and creation of dozens of new jobs will have an immediate impact on the local economy, and the project’s benefits will also radiate throughout the region. I’m proud Mississippi continues to be a place where companies invest with confidence, and I thank the TerraForge team for helping us close out 2025 on an impressive note, stated Governor Tate Reeves.
The project includes construction of a new manufacturing facility that will house two biocarbon processors to transform wood fiber through a combustion-free, low-emissions process into metallurgical-grade biocarbon.
Mississippi has proven time and again that we are a top state for innovation. By locating in Magnolia, TerraForge Biocarbon Solutions is bringing innovative industrial manufacturing to Mississippi and helping modernize an industry that powers our economy. The company’s production of metallurgical biocarbon is precisely the kind of forward-thinking industrial investment MDA is proud to support and welcome to our state, said Bill Cork, Executive Director, MDA.
The Mississippi Development Authority is providing support through the Mississippi Flexible Tax Incentive (MFLEX) program, along with assistance with infrastructure improvements.
Weyerhaeuser has a long history in Mississippi, and we are excited to expand our manufacturing operations through this new joint venture – drawing on a strong workforce and great local support, and building on our investment and positive impact in the state, Devin W. Stockfish said.
Pike County is also assisting with the project.
This announcement marks a significant milestone for Pike County. A multimillion-dollar investment and the creation of high-paying jobs demonstrate the strong future we are building together. We are excited to partner with TerraForge as they become an important part of our growing economy, said Jill Busby, Director, Pike County Economic Development District.
TerraForge Biocarbon Solutions expects to complete the project and fill the jobs by 2027.
