Supercritical extraction equipment. A researcher's hand holds a flask of plant compounds extracted in solvent. They have been extracted using a process known as supercritical extraction. This involves extracting chemicals under high pressure and temperature using carbon dioxide as a solvent. It allows the extraction of compounds from plant matter without using environmentally harmful solvents. This technique has been used by researchers from the Green Chemistry Group at the University of York, UK, to extract wax from waste wheat straw. The wax is valuable to the cosmetics industry and other wax products. Photographed in 2006.
