Hyosung backs Trillium’s bio-acrylonitrile demo plant with $13m Series B funding

South Korea’s HS Hyosung Advanced Materials has deepened its commitment to US-based Trillium Renewable Chemicals by leading a $13 million (€11 million) Series B funding round. The investment follows Hyosung’s existing stake in Trillium since 2022 and positions the Korean conglomerate as the lead backer in the round, joined by Belgium’s Capricorn Partners. The fresh capital will bankroll the operation of Trillium’s demonstration-scale bio-acrylonitrile plant, accelerate process development, and fund engineering work for a future commercial facility.

Trillium’s ‘project falcon’—described as the world’s first glycerol-based bio-acrylonitrile demonstration plant—was completed in February 2026. Commissioning is slated to begin in Q2 2026, with first product shipments expected in the second half of the year. The facility uses waste glycerol, a biodiesel byproduct, as feedstock to replace conventional petrochemical inputs. Acrylonitrile is a critical raw material for synthetic rubbers, high-performance polymers, and carbon fibre production, all key to Hyosung Advanced Materials’ operations.

The partnership underscores Hyosung’s strategic pivot toward sustainable chemistry, leveraging Trillium’s proprietary process to cut reliance on fossil-based acrylonitrile while advancing circular-economy feedstocks.
