Olympic Wire and Equipment Inc. distributes the Danish-made Runi Screw Compactor, which densifies all types of polystyrene to a ratio of 50:1. The odor-minimizing, volume reduction process, which can be hand- or conveyer-fed, breaks up the material and drops it into an auger. The machine then compacts the material into 19-pound/cubic-foot blocks that can be marketed or shipped. The end-product can produce a full overseas container load of 40,000 pounds.
