为了实现回收和/或堆肥生物基塑料包装可以提供的潜在环境效益，重要的是消费者将生物基包装视为环境友好的，但也要正确处理包装。目前的现场实验室研究在德国消费者（n= 281）中进行，并探讨消费者对可回收和可堆肥生物基塑料包装的环境效益的感知是否与消费者如何处理这些包装相匹配。结果表明，消费者只认为可堆肥的生物基包装比化石基包装具有更多的环境效益。然而，消费者以不正确的方式（不符合包装标签上传达的内容）处理可堆肥生物基包装相对频繁。与化石基包装相比，对生物基产品更熟悉的消费者通常更正确地处理可堆肥生物基包装，但不处理可回收生物基包装。因此，尽管主要可堆肥的生物基塑料包装对消费者具有强烈的环境吸引力，但矛盾的是，这并没有转化为适当的处置行动，以充分利用生物基包装实际上可以提供的环境效益。提高消费者对生物基产品的熟悉程度可能是提高可持续处置水平的一个途径。
To realize the potential environmental benefits that recycling and/or composting bio-based plastic packages can deliver, it is important that consumers view bio-based packaging as environmentally-friendly, but also correctly dispose of the packaging. The current experimental lab-in-the-field study was conducted among German consumers (n= 281) and explores whether consumers' perceived environmental benefits of recyclable and compostable bio-based plastic packages match with how consumers dispose of these packages. The results show that consumers only perceive compostable bio-based packages to have more environmental benefits than fossil-based packages. However, consumers dispose of compostable bio-based packages in an incorrect manner (not in line with what is communicated on the packaging label) relatively often. Consumers with a stronger familiarity with bio-based products more often correctly dispose of compostable bio-based packages, but not recyclable bio-based packages, relative to fossil-based packages. Thus, although mainly compostable bio-based plastic packages have strong environmental appeal to consumers, paradoxically this does not translate in the proper disposal actions to fully capitalize on the environmental benefits that bio-based packages can actually deliver. Increasing consumers' bio-based product familiarity might be an avenue to increase the levels of sustainable disposal.
