Abstract

Universities and colleges are becoming models for the rest of the world in sustainability initiatives. A Dubai-based university has taken action by collaborating with two industry entities in the application of the 3 R Model to promote sustainability. This article aims to investigate each phase of this collaboration, which includes a waste management company to collect the community’s mixed plastic; a material recovery facility to segregate the polyethylene terephthalate (PET) plastic; and a sustainable manufacturing solutions entity called DGrade to sustainably transform the PET plastic into fibers that produce over 200 types of fabrics. DGrade synthesizes clothing and supplies from these fabrics that are sold back to the University. This process uses 76 % less energy, 20 % less water (remaining 80 % is recycled back), and lowers carbon emissions by 79 %. Giving PET plastic a second life provides a practical solution to the challenges posed by the global plastic waste crisis and successfully closes the loop on the recycling of PET plastic.
关闭PET塑料回收循环:从塑料到纤维的可持续转变
大学和学院正在成为世界其他地区可持续发展倡议的典范。迪拜的一所大学已经采取行动,与两个行业实体合作,应用3 R模型来促进可持续性。本文旨在调查这种合作的每个阶段,其中包括废物管理公司收集社区的混合塑料;用于分离聚对苯二甲酸乙二醇酯(PET)塑料的材料回收设施;以及一家名为DGrade的可持续制造解决方案实体,该实体将PET塑料可持续地转化为纤维,可生产200多种织物。DGrade从这些面料中合成服装和用品,并将其卖回大学。这个过程减少了76% %的能源消耗,减少了20% %的水(剩下的80% %被回收利用),减少了79% %的碳排放。给予PET塑料第二次生命为全球塑料废物危机带来的挑战提供了一个切实可行的解决方案,并成功地完成了PET塑料回收的循环。
