A method and apparatus for recycling plastic by removing contaminates from plastic film and leaving the film substantially intact. The preferred embodiment is particularly applicable to agfilms. The method comprises pulling used plastic film from the form it is stored into when removed from the field, spreading it open, and removing contaminates from the film. Contaminates are removed with dry or wet processes, or a combination of both. The wet processes may use water, surfactant, detergent, flocculant, solvent, disinfectant or deodorant, and the film is dried after wet processing. If necessary, sections of film containing contaminates that cannot be removed in the downstream equipment, such as glue, may be cut from the film. The discharge of the process is one or more relatively clean and dry film strips that are then wound, ground or melted for reuse. |
