Recycling Materials

Abstract
Materials recycling has become popular not only to save the environment, but it has also become big business. Recyclable materials include: fibers, plastics, glass (a type of ceramic), and metals. Paper (a fiber made from a cellulose composite) recycling is probably the most widely known and common type of recycling. This module introduces concepts of material processing (called pulping) used in recycling paper to create pulp out of post-consumer paper products. The hands-on activity takes the student through the full pulping process from selecting and collecting the material to the ultimate transformation into a new product. Recycled pulp and fiber products can be found everywhere today. It’s important for materials technologists to understand the processes involved and the mechanics responsible for the transformation (recyclability) of the material.
