Driven by European legislation, counties must improve their plastic packaging recycling system to meet ambitious recycling targets. This study analyses the current plastic packaging recycling system in Norway, together with three alternative systems and evaluates their performance on environmental impact and achievement of policy indicators. The alternative systems include measures to increase separation of plastic packaging waste and to increase plastic sorting capacity in Norway. A lower impact on climate change (between 531 kg and 874 kg CO eq. compared to the current system) was obtained for scenarios with high separation of plastic packaging waste. Without better waste separation, increased sorting in Norway resulted in a higher impact on climate change (between 46 kg and 123 kg CO eq.) compared to the current system. Mixed-waste MRFs can help to obtain high recycling rates, but their implementation should be coordinated centrally to avoid potential adverse effects. Furthermore, none of the proposed systems reached the recycling rate targets, showing that improvements are necessary across the entire value chain.
在欧洲立法的推动下,各郡必须改进其塑料包装回收系统,以实现宏伟的回收目标。本研究分析了挪威当前的塑料包装回收系统以及三种替代系统,并评估了它们在环境影响和政策指标达成方面的表现。替代系统包括增加塑料包装废物分类以及提高挪威塑料分拣能力的措施。对于塑料包装废物高度分类的情景,对气候变化的影响较低(与当前系统相比,减少531千克至874千克二氧化碳当量)。如果没有更好的废物分类,挪威增加分拣会导致对气候变化的影响比当前系统更高(增加46千克至123千克二氧化碳当量)。混合废物材料回收设施有助于实现高回收率,但应进行集中协调实施,以避免潜在的不利影响。此外,所提出的系统均未达到回收率目标,这表明整个价值链都需要改进。
