Tuscaloosa, AL – November 5, 2025 – Greenway Steel, a U.S.-based sustainability solutions provider serving the metals and manufacturing supply chain, has announced a partnership with Karmanterra, a leader in biocarbon products for industrial decarbonization, to accelerate the adoption of renewable carbon materials in steelmaking and other high-emission processes.
Under the collaboration, Greenway Steel will work with Karmanterra to identify and advance industrial applications for Karmanterra’s biogenic carbon, a renewable alternative to fossil-based anthracite and coke used in electric arc furnace (EAF) and direct reduced iron (DRI) steelmaking. The partnership will focus on evaluating performance, cost, and emissions benefits across various steelmaking and manufacturing processes.
“Greenway Steel was founded to bridge the gap between emerging clean technologies and the realities of industrial operations,” said Randy Charles, Founder and Manager of Greenway Steel. “With my background in metallurgy and steel production, our goal is to help partners like Karmanterra find the right fit and best opportunity for their technologies within the supply chain. Biocarbon represents one of the most practical near-term solutions to reduce emissions in steelmaking.”
Karmanterra’s renewable biocarbon is engineered to match the metallurgical performance of fossil carbon sources while offering significant lifecycle CO2 reductions. The company’s technology enables steel producers and foundries to meet tightening sustainability targets, including those driven by Carbon Border Adjustment Mechanisms (CBAM) and domestic clean purchasing initiatives.
“Our partnership with Greenway Steel is about integration and impact,” said John Ryan, Founder and CEO of Karmanterra. “Randy’s deep technical experience and industry insight make Greenway an ideal partner to bring our biocarbon solutions into the hands of U.S. steel and metals producers committed to sustainability and competitiveness.”
The companies will jointly engage with select industrial partners in 2025 to conduct pilot programs and develop value-in-use models demonstrating both the environmental and economic benefits of renewable carbon substitution.
