Carbon-neutral Agroforestry-derived Resins to Materials for Automotive applications (CARMA)

There is increasing industrial, regulatory and consumer demand for the use of greener alternatives across a range of everyday products, with a particular focus on formulated non-food items. It is also a key strategy for the UK government and manufacturers to use biobased alternatives to petrochemical-derived ingredients across the chemical industry. Bio-refining of a range of low-value biomass residues offers a way to produce intermediate chemicals to replace fossil-based materials, whilst simultaneously increasing their value and reducing their impact on the environment. However, current biorefining technologies are wasteful, inefficient and often unprofitable.Bio-Sep, using its novel, patented ultrasonic processing technology, aims to make a step-change in biorefining while stimulating investments in the UK bioeconomy. In collaboration with a strong consortium of global leaders in process innovation, chemicals, composites and automotives, Bio-Sep aims to optimise the Sonichem technology for specific, renewable, consistent, and widely-available UK biomass and generate platform chemicals directly relevant to the paints, coatings, cosmetics, construction, resins, pharmaceuticals, and additives markets. The consortium will explore the use of lignin to pioneer composite resin formulations that contain high-levels of renewable, non-petrochemical content, and utilise low-carbon feedstocks. As part of the project, applications of this material to composites for automotive applications will be investigated.The main outcome of the project will be optimised and validated ultrasonic fractionation of UK biomass residues, achieved in a commercially-viable and environmentally-sustainable manner under mild operating conditions, to produce high-quality lignin. The lignin will be demonstrated as suitable for the production of renewable, low carbon and bio-based feedstocks for composite materials relevant to the automotive sector. These outcomes allow Bio-Sep to provide a basis for the scaling of the innovation, promote the Sonichem biorefinery concept more widely, and advance subsequent commercialisation with exploitation partners across the chemicals industry.
