Since plastics account for approximately 20 percent of the landfill volume, recycling plastics plays a significant role in reducing solid waste flow. Students must be educated in the methods of recycling plastics and better controlling the properties of products made from recycled materials. This project is enhancing materials recycling experiments by adding study of the microstructural change in plastics due to recycling. These experiments are done using a scanning electron microscope. These experiments include collecting and cleaning postconsumer containers, grinding, extrusion compounding and pelletizing, dry injection molding, and analyzing the structure of recycled plastics. With the implementation of this project, students are able to better understand the change in polymeric structure caused by recycling, and to control the properties of the recycled materials using the structure property relationship. Students in the technology majors and non-science-majors are gaining fundamental understanding and practical experience through this series of experiments. They are gaining knowledgeable insight into reducing, reusing, and recycling plastics. *

由于塑料约占垃圾填埋场体积的20%，因此回收塑料在减少固体废物流量方面发挥着重要作用。学生必须接受回收塑料的方法和更好地控制由回收材料制成的产品的性能的教育。 该项目通过增加对塑料因回收而发生的微观结构变化的研究来加强材料回收实验。这些实验是使用扫描电子显微镜完成的。这些实验包括收集和清洁消费后容器、研磨、挤出复合和造粒、干法注塑成型以及分析回收塑料的结构。通过本项目的实施，学生能够更好地理解回收引起的聚合物结构的变化，并利用结构性能关系控制回收材料的性能。 通过这一系列的实验，使理工科和非理工科的学生获得了基本的认识和实践经验。他们对减少、再利用和回收塑料有着深刻的认识。 *
