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

点击翻译按钮获取中文摘要

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.
