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

PRISM是一种基于智能标签的快速分拣包装的新方法，该智能标签具有不可见的标记，可以使用MRF中使用的现有高速光学分拣系统进行微小修改来检测和分拣。标签和标记通过回收过程被完全去除。该技术使用商业标签和装饰方法，使用高性能发光化合物编码，对目标物流进行分类，包括食品接触塑料、生物塑料、化学包装、汽车塑料、黑色塑料和不同等级的塑料。分拣是通过对现有近红外分拣机的改造来完成的。这项新技术可以通过有效的方式对食品用PP包装、HDPE牛奶瓶和带套PET等材料进行分类，提高回收工厂的产量，并增加食品级塑料的回收率，为回收塑料开辟新的市场。该技术将与所有NIR分选设备兼容。它将帮助品牌所有者，以确保包装达到回收循环和提高英国回收性能。

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