Rhea-AI Summary

Weyerhaeuser (NYSE: WY) and Aymium entered an MOU and formed a joint venture, TerraForge Biocarbon Solutions, to produce and sell 1.5 million tons of sustainable biocarbon annually for metals production.

Plans start with a jointly owned facility adjacent to Weyerhaeuser's McComb, Mississippi lumber mill, targeted to come online in 2027, and a platform that could convert over 7 million tons of Weyerhaeuser-provided wood fiber to deliver metallurgical-grade biocarbon as a drop-in coal replacement across iron, steel, silicon and ferro-alloys.

The MOU calls for securing long-term biocarbon sales agreements and identifying additional sites across Weyerhaeuser's footprint, leveraging Weyerhaeuser's timberlands and Aymium's proprietary, combustion-free technology.

Positive

• Target production of 1.5M tons biocarbon annually

Key Terms

2 terms

biocarbon technical

"convert wood fiber into biocarbon products, accelerating scale supply"

Biocarbon is carbon captured and stored in solid materials made from plant or organic waste—for example biochar or wood-based bricks—created by heating biomass in low-oxygen conditions. For investors, biocarbon matters because it can act like a long-term “parking space” for atmospheric carbon, enabling companies to reduce reported emissions, generate carbon credits, or supply sustainable raw materials, all of which can affect regulatory costs, market demand, and valuation.

metallurgical-grade technical

"deliver 1.5 million tons of metallurgical-grade biocarbon annually"

Metallurgical-grade describes a metal or mineral that meets purity and quality standards suitable for heavy industrial uses like steelmaking, casting, or alloying rather than for high-tech or medical applications. Think of it as a kitchen-grade ingredient good for everyday cooking rather than a pharmaceutical-grade chemical — acceptable for large-scale manufacturing but lower-priced and lower-margin. Investors watch metallurgical-grade supply, demand and price because it determines which industries can use the material, influences profit margins for producers, and signals shifts between basic industrial demand and higher-value specialty markets.

Partnership will expand manufacturing platform to convert wood fiber into biocarbon products, accelerating scale supply to global metals producers

SEATTLE, Dec. 11, 2025 /PRNewswire/ -- Weyerhaeuser Company (NYSE: WY) and Aymium today announced they have entered a memorandum of understanding (MOU) to partner to produce and sell 1.5 million tons 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, Miss., 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 tons of wood fiber — provided exclusively by Weyerhaeuser — to deliver 1.5 million tons of metallurgical-grade biocarbon annually as a drop-in replacement for coal in iron, steel, silicon, ferro-alloys and other metals production.

Aymium has generated a significant global sales pipeline based on years of trials with leading global metals producers. The company's patented products are engineered to immediately replace coal and coke without the need for capital investment or process modification, and with superior carbon levels, energy value, handling and environmental attributes to 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," says Devin W. Stockfish, president and chief executive officer of Weyerhaeuser. "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."

"The reliability, scale of sustainable supply and forestland expertise of Weyerhaeuser provide unmatched sourcing security of our main raw material to support expansion," says James Mennell, CEO of Aymium. "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."
