Green Rose Chemistry uses the S4 Research Framework developed by the Green Chemistry Centre of Excellence at the University of York. In its 8 years of development with industrial partners, the S4 framework has solved a number of difficult challenges, from solvent replacement to solvent development. Check out some past projects below to see how Green Rose services could help you.
SOLVENTS FROM CITRUS WASTE
Limonene is naturally found in orange peels, and makes a surprisingly good solvent. It is known for use in cleaning applications, but GCCE researchers used S4 to go beyond the typical applications and explore the boundaries of where limonene and its derivative, p-cymene, can be applied.
TRANSFORMING WASTE CELLULOSE TO NEW SOLVENT
When the GCCE team developed a new, cost-efficient process for producing a chemical called Cyrene from waste sawdust, the S4 team recognised the great green solvent potential. In partnership with Circa Group, the GCCE worked to identify solvent applications and commercialise this product. Cyrene is now being produced at large scale and distributed around the world by Merck.
PUTTING THE PRESSURE ON CO₂
Carbon dioxide is best known as a source of global warming, but with clever chemistry and just the right amount of pressure, it can be put to work as a tunable solvent. By intelligently choosing the right temperature and pressure for the application, S4 researchers have uncovered new applications of CO₂ in valorisation of wheat straw, converting waste straw into bio-product gold.
