Abstract
Commercial and pilot‐scale methods for the re‐use of clean, unmixed scrap plastic are described. Mixed scrap presents greater problems and efforts have been made to improve its properties with additives or by altering its composition. Separation methods are surveyed. Mixed wastes find limited re‐use in low quality products. Re‐use of waste plastics as fuel is now probably the most economical alternative. Economic rather than technical obstacles remain for this recycling.
