Real-world laboratories as an approach for reducing plastic outflow into the North Sea

Global plastics production has grown rapidly in recent decades and is leading to an increased discharge of plastic waste into the environment, presenting a complex socio-ecological problem. The southern North Sea and its tributaries are affected by plastic pollution due to dense population, industrial use, as well as tourism and recreational activities. A paradigm shift is necessary to reduce the outflow of plastic waste from rivers and inland waters into the North Sea. In order to foster a socio-ecological transformation, one opportunity is to involve stakeholders from all sectors, who regulate, produce, trade, use, recycle and dispose plastic products, through a transdisciplinary process. Real-world laboratories as a science-practice interaction approach are conceptualised to produce robust knowledge to solve real-world environmental and societal challenges. The aim of this study is to determine how the design and early implementation phases of real-world laboratories should be executed to achieve socio-ecological transformation. We assessed the case study of an inaugural regional stakeholder meeting of the real-world laboratory ‘Plastic-FREE-sia’ in Northwest Germany by in-event observations and a subsequent participant survey. Our findings of this stakeholder workshop highlight the significance of involving diverse stakeholders from multiple sectors in the real-world laboratory process and emphasise the need for balanced representation. The interests, benefits and goals of individual stakeholders must be identified from the outset and aligned with the socio-ecological problem setting, in order to prevent conflicting objectives. Concluding recommendations for the design and early implementation phases of future real-world laboratories are formulated.
