Tests of plastic packaging in Finland and Norway exposed products that are lost in the sorting process and are not recycled. Products that proved challenging to sort or recycle were then presented to their producers. To assist producers in making favourable decisions, fact sheets with design guidelines were developed for common plastics, HDPE, PP, LDPE and bio-based and biodegradable plastics, to highlight which design choices best help improve recyclability. These also include Norway-specific information on the downstream value chain for plastics. Producers have shown a willingness to improve their products to increase the level of recyclability. These developments show how higher recycling rates of plastic packaging can be achieved by supporting Nordic producers in implementing design for recyclability principles when designing their packaging.
