Wood is Estonia's most important bio-based raw material, the skilful processing of which creates high added value, carbon binding products. Today, Estonian universities do not have a unified action plan and infrastructure for coordinated research and development (R&D) and for offering industrial solutions throughout the entire value chain. Therefore, the infrastructure is created for linking 14 structural units of 8 institutes of 3 universities. This synergy enables to carry out interdisciplinary, high quality R&D activities of wood valorisation. The infrastructure creates new opportunities for training young researchers and provides a strong base for international cooperation. An integrated contact point will be created for effective marketing of services of the infrastructure. R&D of the infrastructure covers mechanical, chemical, biochemical and thermochemical valorisation of primary and secondary wood and can take the Estonian wood science and industry to a new development level.

Wood or lignocellulosic biomass more generally, is a readily available renewable resource, offering sustainable solutions for our growing human population. The core wood polymers - cellulose, hemicellulose, and lignin - serve as fundamental components, extending beyond paper production to produce valuable wood sugars, textile fibers, thermoplastics, and fine chemicals. In our project, we are developing enzyme technologies utilizing extremophilic microbe-derived enzymes to break down and modify lignin, remove toxic phenolic compounds, convert cellulose into wood sugars, and advance enzyme-catalyzed cellulose technologies. Additionally, the project focuses on advancing technologies for converting kraft, hydrolysis (and organosolv) and synthetic lignins into porous materials, thermoplastics, and cutting-edge catalysts.

The project focuses on the DAL technology developed at TalTech, which aims to purify Kraft lignin to a very low ash content (≤0.05%). DAL uses green solvents and has a simpler process than competing technologies. Within the project, the technology’s innovation readiness level (CRL and BRL) will be increased by collecting market feedback, developing a business model, and strengthening the necessary competencies. As a result, the commercialisation potential of the DAL technology will increase.
