A pre-wash process and apparatus for recycling polymer tubing contaminated with large amounts of organic matter, soil, and so forth. The pre-wash process includes the steps of sizing the contaminated polymer tubing into small pieces, conveying the polymer tubing on a first conveyor into a rotating wash trommel, washing the polymer tubing in the rotating wash trommel, conveying the polymer tubing on a second conveyor through a pre-rinse stage and then into a rotating rinse trommel, rinsing the polymer tubing in the rinse trommel, discharging the polymer tubing from the rinse trommel into a float/sink tank, passing the polymer tubing through the float/sink tank to a third conveyor, and conveying the polymer tubing into a suitable container for delivery to a final wash and pelletizing process. The wash trommel and rinse trommel each comprises a rotating cylinder with internal helical flighting that causes intense rolling and agitation of the polymer tubing. The rinse trommel is perforated so that fluid and contaminants are separated from the polymer material. The conveyors are made of chain mesh or other suitable open structure. Linear motion shaker screens are placed below the second conveyor and the rinse trommel to separate contaminants from the recirculated wash and rinse fluids, respectively.
