Creating profitable and successful production of high purity lignin, sugar and penta, hexa carbon carbohydrates from hardwood
The BBI JU Flagship SWEETWOODS plant is scaling a novel hardwood cascading biorefinery process in Estonia.
Using proprietary biofractionation technology, the plant efficiently converts wood processing residues into high-purity cellulosic sugars and high purity lignin called LIGNOVA™ at an industrial scale. The process combines innovative pre treatment technology with enzymatic solutions to provide sugar recovery levels of over 90 per cent with exceptionally high-quality lignin. LIGNOVA™ materials can be produce to different grades and are used for production of biocomposites for injection molding, different resins and adhesives, rigid polyurethane foam panels for insulation and many other applications.
The global lignin market size was estimated at USD 1.04 billion in 2022 and is expected to grow at a compound annual growth rate (CAGR) of 4.9% from 2023 to 2030. The value of the xylitol is expected to rise from US$ 713.4 million in 2023 to US$ 1,086.8 million in 2033.
Carbon footprint of the whole fractionation process is 201 kg CO2 eq based on 1 ton of dry input material (wood residues) which is significantly lower than fossil fuel. The approach will reduce waste from biorefining processes by at least 80 per cent over the current state-of-the-art.
The extension of the hardwood value chain to produce need products like insulation and elastomeric foams and biochemicals can create jobs in local community
Foresters, technology providers, researchers, product market actors (e.g., manufacturers, packaging sector, agri-food sector, consumer goods).
