N2 - The enzymatic transformation of poly(ε-caprolactone (PCL) into repolymerizable oligomers in supereritical carbon dioxide (scCO2) using an enzyme was carried out in order to establish a sustainable chemical recycling system for PCL, which is a typical biodegradable synthetic plastic. The enzymatic conversion of PCL beads having an Mn of 110 000 using Candida antarctica lipase (lipase CA) in scCO2, containing small amounts of water quantitatively afforded CL oligomers at 40°C. The CL oligomers were readily repolymerized using the same enzyme to produce high-molecular weight PCL.
