Researchers from the University of Wisconsin, Madison led by chemical engineer James Dumesic have developed an technique to convert fructose into a polymer precursor. The technique makes use of 5-hydroxymethylfurfural (HMF), which can easily be converted into furandicarboxylic acid (FDCA)– similar in structure to a petroleum-based precursor for the type of plastic commonly used in plastic bottles. In this process, 90 percent of fructose is converted into HMF by dehydrating fructose by adding an acid to strip off water molecules. To prevent the newly formed HMF from further reaction with fructose, they added a solvent. Once the reaction was complete, the solvent was boiled away, leaving the HMF to be turned into plastic.
This technique has the potential to allow industry to make plastics not only from high-fructose corn syrups but other plant materials too. It could also server to reduce reliance on petroleum for making plastics and also reduce carbon dioxide emissions.
