What Fibenol does

Fibenol (legal entity OÜ Fibenol) is an Estonian biomaterials producer that converts sustainably sourced Nordic hardwood into high-purity lignin, cellulosic sugars, and specialty crystalline cellulose using its proprietary Sunburst™ pre-treatment technology. The company operates a flagship biorefinery in Imavere, Estonia, fully functional since 2023 with nameplate capacity of approximately 6,500 tons per year of lignin and 20,000 tons per year of cellulosic wood sugars, powered entirely by renewable energy and sourcing feedstock within a 50 km radius. Products are marketed under the trademarks LIGNOVA® (Crude and Pure grades of hydrolysis lignin) and WoodCell™ (crystalline cellulose, MCC), with certifications including TÜV AUSTRIA OK compostable HOME/INDUSTRIAL, OK biodegradable SOIL, ISO 9001, ISO 14001, and an Environdec-verified Environmental Product Declaration.

The business model is B2B direct enterprise sales of industrial biomaterial inputs, with pricing quoted per engagement and typical contract terms extending across multiple years. Target customers span construction materials (phenolic resins, insulation foams, bio-asphalt), packaging (barrier coatings, fiber-based and bioplastic substitutes), food/feed/pharma (non-food-competing fermentation feedstocks such as C5 xylose and C6 glucose), biofuels/biochemicals, and emerging energy storage applications (lignin-derived hard carbon for sodium-ion batteries). Distribution relies on field sales, sample-driven qualification, co-development under EU-funded Circular Bio-based Europe JU consortia, and named partnerships with offtakers such as Svevia, Taisei Rotec, Subeco, Kroonpak, UP Catalyst, and ÄIO.

Fibenol is a 100% privately held spin-off of Graanul Invest Group, one of Europe's largest wood pellet producers, and operates with an estimated headcount of around 50 employees. The company differentiates on conversion efficiency (over 90% of woody biomass converted into high-value outputs), minimal chemical and water use, drop-in compatibility with existing industrial processes, and a regulatory and certification stack that supports procurement in regulated end markets.

Core offering

Fibenol operates a hardwood biorefinery that uses its proprietary Sunburst™ fractionation technology to convert forestry and wood-industry residues into high-value biomaterials. Its commercial product portfolio includes LIGNOVA® hydrolysis lignin (Crude and Pure grades), cellulosic wood sugars (C5 xylose, C6 glucose, and C5/C6 mix), and WoodCell™ crystalline cellulose (MCC). These products are sold as drop-in biobased substitutes for fossil-based chemicals to industrial customers in construction, packaging, chemicals, food/feed, biofuels, and energy storage.

Product overview

Fibenol operates as a biomaterials company offering a portfolio of wood-derived products produced via its Sunburst™ fractionation technology at its flagship plant in Estonia (fully functional since 2023). The core product line includes LIGNOVA® lignin (in Crude and Pure grades), cellulosic wood sugars (C5 xylose, C6 glucose, and C5/C6 mix), and specialty crystalline celluloses including WoodCell™. These products serve as drop-in biobased substitutes for fossil-based chemicals across industries including construction, packaging, food/feed/pharmaceuticals, and bioenergy, with applications ranging from plywood adhesives to battery materials.
