Reduction in polystyrene with activated agent

DETAILED DESCRIPTION We claim: 1.
A method to reduce volume of polystyrene foams where foam products are subject to the vapor of terpenes in an enclosed area for a period of time until they are reduced to a viscous fluid, said terpenes being heat treated within the previous 90 days to activate them.
2.
The method in 1 where said polystyrene foams are reduced in volume by the effect of sprayed liquids containing terpenes in addition to said vapors.
3.
The method in 1 where said terpenes consist primarily of d-limonene.
4.
The method in 2 where said terpenes consist primarily of d-limonene.
5.
The method in 1 where said enclosed area is a plastic bag.
6.
The method in 2 where said enclosed area is a plastic bag.
7.
The method in 2 where a tank is used to store polystyrene foam products and said terpene material is introduced into said tank, and a heater within said tank activates the terpene materials by heating them to their boiling point.
8.
The method in 2 where a tank equipped to spray a terpene material onto polystyrene foam products inside a tank which contains the vapors of the terpene.
9.
The method in 8 where said terpene is D-limonene which has been activated by heating to its boiling point within the previous 90 days.
10.
The method in 1 where said terpene is an isoprenoid compound or an oxygenated isoprenoid compound.
11.
A system to reduce the volume of polystyrene foams wherein said polystyrene foams are exposed to vapors of d-limonene over an extended period in a container which prevents escape of said vapors and where a heater heats vapors of said d-limonene.
12.
The system in 11 where said vapors are contained in a tank or vessel which has ports for addition of polystyrene foams, for addition of D-limonene, and for withdrawal of dissolved polystyrene resins.
13.
The system in 12 where said vapors arise from a combination of a spray of the liquid d-limonene and vapors transported from a second tank, said transported vapors heated to the boiling temperature to activate them, and the polystyrene foam in its reduced state is withdrawn by flow to said second tank
