Akron-based Polyflow has a fantasy: turning trash to treasure. It's one that seems to be coming true. Transforming discarded tires, carpet and other polymeric trash into readily useable fuel, Polyflow says that what distinguishes it from others doing the same thing is the range of waste that the Polyflow process can utilize. Tires, carpet, PVC pipes and plastic children's toys that would otherwise clog up a landfill are broken down to oil that is sold to local blenders. For every ton of waste processed, the system yields .7 tons of fuel.
