Low temperature microwave pyrolysis (< 200°C) is shown to be an energy efficient method to produce char and oil suitable for upgrading for use as sustainable substitutes for fossil fuels. Applying a closed loop system, CO2 can be internally recycled to sustain the processes and add value by extracting secondary metabolites including fatty acids, wax esters and fatty alcohols.
“This has been a really exciting project to work on” says co-author Brigid Lanigan.
“We’ve been very fortunate to be able to work in this developing area and with the establishment of the Green Chemical Technology Facility, we will hopefully be able to expand on this research in the future.”
The group are also looking into other potential commercial applications for these wheat straw products including lubricants, food flavourings and cosmetics!
