Plastic Packaging Recycling using Intelligent Separation technologies for Materials (PRISM)

棱镜是一种基于带有不可见标记的智能标签的快速分拣包装的新方法，使用现有的用于MRF的高速光学分拣系统，只需稍加修改即可检测和分拣。这项技术使用商业标签和装饰方法，以高性能发光化合物编码，对目标流进行分类，包括与食品接触的塑料、生物塑料、化学包装、汽车塑料、黑色塑料和不同等级的一种塑料。分拣是通过对现有的近红外分拣机械进行改进来完成的。这项新技术可以通过对用于食品的PP包装、HDPE奶瓶和袖状PET等材料进行有效的分选，提高回收工厂的产量，并提高食品级塑料的回收率，并为回收塑料开辟新的市场。这项技术将与所有近红外分选设备兼容。它将帮助品牌所有者确保包装到达回收循环，并提高英国的回收性能。

PRISM is a new way of rapidly sorting packaging based on intelligent labels with invisible markers that can be detected and sorted using existing high-speed optical sorting systems used in MRFs with minor modifications. This technology uses commercial labelling and decoration methods which are coded with high performing luminescent compounds to sort targeted streams including food-contact plastics, bioplastics, chemical packaging, automotive plastics, black plastics and different grades of one plastic. Sorting is accomplished using modifications to existing NIR sorting machinery. The new technology can boost recycling plant yields with efficient ways of sorting materials such as PP packaging used for food, HDPE milk bottles and sleeved PET and increase recovery of food grade plastics and open up new markets for recovered plastics.This technology will be compatible with all NIR sorting equipment. It will help brand owners to ensure that packaging reaches the recycling loop and boost UK recycling performance.
