The invention presents classes of thermoplastic, biodegradable compositions. Tests indicate that these compositions exhibit good mechanical properties, and readily degrade in the presence of microorganisms. The compositions of this invention are useful for producing injection-molded, thin-walled articles that are capable of appreciably degrading in the sewage system within thirty (30) days.
