Cellulose, one of nature's most abundant polymers, is produced in significant quantities in many farmed crops. Yet it is not a human food source - so the use of cellulose in high value materials does not compete with, but potentially complements, food production. This lecture covered work afoot at the University's Centre for Sustainable Chemical Technologies into processing cellulose into high value materials that gives access to renewably-derived recyclable materials with a range of diverse applications.
