Plastics from Potatoes, Rubber from Rice

With over 80% of organic carbon being present in the form of cellulose, lignin and starch, it is unsurprising many groups have attempted to use these as feedstock chemicals and materials. Extensive hydrogen bonding makes the plasticisation of starch and the dissolution of cellulose difficult. This talk shows that the incorporation of a simple salt can lead to a flexible plastic with mechanical properties similar to oil derived plastics. Most importantly these plastics are recyclable and ultimately compostable.A lecture by Andrew Abbott, University of Leicester 26 November 2018The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/plastics-potatoes-rubber-riceGresham College has been giving free public lectures since 1597.
