Plastics are globally dispersed and reported at a growing rate and increasing concentrations in marine ecosystems. Due to their persistence in aquatic environments, the global plastic problem will last for decades. In this context, the removal of plastic at the source prior to reaching the marine environment is instrumental. Hence, plastic detection methods and plastic remediation measures are urgently needed and may become obligatory in the near future. A first prerequisite to taking effective plastic remediation measures is to know where and when action should be taken. PLUXIN addressed this challenge by developing a plastic dispersal model, integrating in situ data, experimental insights, and remote sensing to enhance our understanding of plastic distribution. To do so, PLUXIN integrated Flanders' expertise in hydrology, circular economy, and plastic-related research. Based on standardized sampling protocols, in situ sampling and remote sensing, quantifying plastic flux, identifying accumulation zones and transport routes, we identified that plastic is everywhere, that plastic moves and accumulates, and that not all plastic flows towards the sea. These groundbreaking insights from the PLUXIN project have catalyzed impactful national and international initiatives and projects (cfr. impact timeline). So, besides the scientifically oriented targets, PLUXIN also stimulated innovation in Flemish companies through future valorization efforts. Collaborative efforts have sparked new interactions, amplifying our collective impact on a broader international scale. The project's findings were disseminated through abstracts, publications, workshops, conferences, media outreach, and a short movie highlighting key results.
