The Golden Isles Conservation Center opened yesterday in Nahunta and will use technology invented by an Italian to reduce 80,000 tires a year into their original, marketable components. The plant can process scraps of 450 tires per hour by heating them to break them down into 150 pounds of oil, 150 pounds of carbon black, 100 pounds of gas and 31 pounds of steel. The plant, smaller than originally anticipated, will employ five people.
