Compostable thermoplastic products

Process for composing thermoplastic material including the steps of providing thermoplastic material including a thermoplastic polymer and polymeric composting promoting agent selected from the group consisting of metal complexing agents and metal complexes, and mixtures thereof, in a composting effective amount to convert in the presence of oxidizing metal selected from a group consisting of copper, iron, manganese and cobalt, to an active oxidant, contacting said thermoplastic material with a media containing oxidizing metal selected from a group consisting of garden waste, food waste, paper, wood chips, sewage sludge, mixed solid organic waste, sewage sludge and mixed solid organic waste, lime, manure, and liquid media solutions of oxidizing metals, to cause said oxidizing metal to convert said polymeric composting converting agent to said active oxidant in an amount sufficient to cause said active oxidant to thermally degrade said thermoplastic polymer to a low molecular weight material having enhanced biodegradability under composting conditions and concomitantly subjecting said thermoplastic material to composting conditions to at least partially biodegrade said low molecular material.
