<p>A method of disposing of a biodegradable plastic comprises the step of exposing the biodegradable plastic to a hot alkaline solution. The biodegradable plastic is a polyhydroxyalkanoate copolymer comprising two randomly repeating monomer units wherein the first randomly repeating monomer unit has the structure: wherein R1 is H or a C¿1-2? alkyl, and n is 1 or 2; and the second randomly repeating monomer unit has the structure: wherein R?2¿ is a C¿3-19? alkyl or a C3-19 alkenyl. At least 50% of the randomly repeating monomer units have the structure of the first randomly repeating monomer unit.</p> |
