In order to combat climate change and environmental degradation and pollution, governments and companies around the globe have pledged to decarbonise their economy and some have outlined a clear goal to move towards a fully renewable economy, including a bio-based chemical and fuel sector. However, with high raw material costs compared to the petrochemical industry, the bio-based industries have been struggling to win over markets. Thus, the use of currently unwanted or underused waste materials represents a promising opportunity to drastically reduce the cost of bio-derived products.
Only 50% of the 70M tonnes of European waste wood can currently be recycled, resulting in disposal costs of around £1B annually. In addition, over 1B tonnes of waste biomass are available globally every year in the form of forestry and agricultural residues. These materials can be used as a replacement for crude oil to produce common chemicals, new materials and sustainable fuels. However, effective and economical conversion technologies are required to realise the potential these materials hold.
So called lignocellulosic biomass is comprised of three main polymers: lignin, cellulose and hemicellulose. For its effective valorisation, these three components are to be separated. Cellulose is a widely used material for the production of paper, hygiene products and textiles. Other applications include various packaging materials, films, thickeners, emulsifiers and additives to improve properties of plastics. Lignin hold great promise as a starting material for glues and adhesives or the use in thermoplastics. Hemicellulose can be turned into a variety of bulk and specialty chemicals.
The overall objective of the project was to evaluate the BioFlex process, a chemical technology that separates the three components, for its market potential and to produce a roadmap for its further development. The market potential was to be assessed both for the direct sales of the process outputs (cellulose and lignin) as well as for the purpose of selling the technology (licensing).
