Bio-based Production of Crotonic Acid by Pyrolysis of poly(3-hydroxybutyrate) Inclusions

Bio-based material development has become a new focus globally due to limited supply, increasing price of fossil fuel, and demands for environment sustainability. Current industrial production of crotonic acid through petrochemical route has several drawbacks: i) non-renewable, as it is derived from...
