Trillium Renewable Chemicals closes $13 million Series B to operate world’s first bio-based acrylonitrile plant
Trillium already built the world's first bio-based acrylonitrile demonstration plant. The $13 million Series B means they can actually keep its lights on, and plan for what's next.
Just over a week after Teknovation reported on the Knoxville company reaching industrial scale with construction of the world’s first bio-based acrylonitrile demonstration plant in Texas complete, Trillium Renewable Chemicals announced today it has closed a $13 million Series B to fund operations of that plant, continue pilot-scale innovation and allow for advanced stage engineering design of its first commercial plant.
The round was led by HS Hyosung Advanced Materials, a South Korean advanced materials firm, with participation from Capricorn Partners.

Young-Joon Lee, Senior Vice President of HS Hyosung Advanced Materials and lead investor, explained what this milestone meant for the company’s trajectory.
“Completion of Project Falcon demonstrates that Trillium’s technology is ready for industrial validation. Accessing sustainable acrylonitrile is an important milestone for the industry, and Project Falcon will prove that it can be scaled to produce a viable, drop-in sustainable product,” he said.
Wouter Van de Putte of Capricorn Partners said the completion of the Texas demonstration facility substantially advances Trillium toward commercial manufacturing, pointing to both the company’s technical performance and its ability to execute at industrial scale.
Commissioning of Project Falcon is scheduled for the second quarter of 2026, with product shipments expected later this year.
