Recycled rubber from scrap tires replaces petrochemicals.(PROCESS TECHNOLOGY)

An engineered rubber powder called PolyDyne can offset a significant percentage of the oil needed for the manufacture of many synthetic rubber and other petrochemical products, says Lehigh Technologies Inc., Naples, Fla. PolyDyne is made by grinding rubber from recycled scrap tires into an ultrafine powder. About nine and a half gallons of petroleum are needed to make the various petrochemicals that comprise just one tire.
