ABSTRACT:
This invention is a method to speed up and prevent inconsistent rates of reaction in the reduction of volume of polystyrene foam products by the application of a liquid and vapors of a terpine or isoprenoid compound where a heat activation within 90 days of the use provides maximum reactivity. In one embodiment the process is localized by the addition of heaters in the processing vessels or tanks to insure active agent form of d-limonene reduction agent.
