Clean Synthesis & Platform Molecules
- Conversion of various forms of waste biomass to platform chemicals (bioPMs)
- Use of bioPMs to produce higher-value chemicals such as monomers, solvents, pharmaceuticals, lubricants and home and personal additives
- Development of new catalysts with a specific focus on heterogeneous catalysts with controllable and tunable porosity and surface functionalization
- Finding alternatives to catalysts that currently require the use of non-abundant elements
- Adaption of our current catalytic system to flow, thus aiding scale-up and often
improving process efficiency
- Development of Clean Synthetic Techniques such as microwaves, ultrasound and alternative solvents thus reducing the environmental impact of various chemical transformations
- Development of metrics, toolkits and standards for the promotion of sustainable chemicals
- Conversion of CO2 to value added chemicals
- Organocatalysis using natural products
- Development of green solvents to replace traditional polar aprotics and other petrochemically derived solvents
- Research on the controlled microwave decomposition of biomass.
- Optimizing process conditions for the preparation of liquid fuel (intermediate),
solid fuel and chemical products.
- Designing associated microwave processing equipment.
- Proving processes in continuous mode and in production of multi Kgs quantities of products.
- Producing products and intermediates for testing and further work with industry and in collaboration with external organisations.
- Utilising naturally abundant resources and in particular agricultural and food by-products to develop a range of materials which take full advantage of the chemical composition, rich functionality and structure in plant metabolites and other biomass.
- Collaborating in and leading major industrial consortia projects to deliver products for a range of industrial applications, such as Starbons® and the TSB Wet Waste collaboration.
