Weyerhaeuser and Aymium Enter Agreement to Rapidly Scale Biocarbon Market

(Weyerhaeuser) Partnership will expand manufacturing platform to convert wood fiber into biocarbon products, accelerating scale supply to global metals producers -- 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."
