Implementing Plastic Recycling Experiments for Improvement of Undergraduate Laboratory Education in Materials Technology

以来 塑料包装约占20%， 固体废物量，回收塑料将发挥 在减少固体废物的数量方面发挥了重要作用， 垃圾填埋场的数量和空间在全国减少。 必须教育学生回收材料的方法 以减少未来的浪费。该项目旨在 改进材料实验室专业和非专业指导 通过展示一系列典型的塑料， 回收实验，包括收集，研磨， 回收塑料的加工、测试和分析。的 所要求的设备包括一个塑料袋， 挤出机，光学显微镜和塑料硬度计。 这些仪器和设备是典型的 回收、质量控制和性能鉴定 塑料.材料方面的理论和实践经验 回收将使学生了解减少 固体废物，保护自然资源和保护 环境这个项目可以作为一个模式， 全国的本科院校， 了解回收材料的作用和需要， 保护我们的环境和自然资源

Since plastic packaging accounts for approximately 20 per cent in volume of the solid waste, recycling plastics will play a significant role in reducing the volume of solid waste to the landfills of decreasing number and space in the nation. Students must be educated in the methods to recycle materials in order to reduce future waste. This project is intended to improve materials laboratory instruction for major and non- major undergraduates by presenting a series of typical plastics recycling experiments, including collecting, grinding, processing, testing and analyzing of recycled plastics. The requested equipment includes a plastics granulator, an extruder, an optical microscope and a plastics hardness tester. These instruments and equipment are typical of those used in the recycling, quality control and property identification of plastics. The theoretical and practical experience in materials recycling will give students knowledgeable insight in reducing solid waste, conserving natural resources and protecting the environment. This project could serve as a model for undergraduate institutions in the nation for creating an understanding of the effect and need of recycling materials for the conservation of our environment and natural resources.
