There is low utilisation of plastic waste in the Nordic region and only a fraction of plastic materials go back into production processes through reuse and recycling practices. This paper aims to increase knowledge concerning factors that inhibit demand for recycled plastics, and to identify critical barriers for plastic recycling across the regional plastics value chain. A literature review and targeted interviews with key actors across the plastics value chain enabled the mapping of interactions between the major actors and identified hotspots that act as barriers to the flow of plastic materials. Barriers identified include the lack of both supply and demand of recycled plastic and are mainly attributed to the fragmented market of secondary materials. The main hotspots identified are the low demand due to price considerations, insufficient traceability and transparency in value chain transactions, and general design deficiencies in the recyclability of products. Value chain coordination is considered as the most important intervention by the interviewees, followed by the need for increased investment in innovation and technology development. Complementary measures that could counteract the identified barriers include public procurement for resource efficiency, ban on the incineration of recyclable materials, and specifications on the design of plastic products for reducing the number of different polymers, and the number and usage of additives.
北欧地区对塑料废物的利用率很低,只有一小部分塑料材料通过再利用和回收实践返回生产过程。本文旨在增加有关抑制对再生塑料需求的因素的知识,并确定整个区域塑料价值链中塑料回收的关键障碍。通过对塑料价值链中主要参与者的文献回顾和针对性访谈,绘制了主要参与者之间的相互作用图,并确定了作为塑料材料流动障碍的热点。确定的障碍包括再生塑料供应和需求都不足,这主要归因于二手材料市场的分散。确定的主要热点是由于价格考虑而导致的低需求,价值链交易中的可追溯性和透明度不足,以及产品可回收性的一般设计缺陷。受访者认为,价值链协调是最重要的干预措施,其次是需要增加对创新和技术开发的投资。可以抵消已确定障碍的补充措施包括资源效率的公共采购、禁止焚烧可回收材料、以及减少不同聚合物数量和添加剂数量和用途的塑料产品设计规范。
