The negotiations for a new treaty to govern the ‘full lifecycle’ of plastics face a major challenge: designing a strong treaty, quickly, that is acceptable to most of the international community of states. Although diplomats play a critical role in accomplishing this task, scholars and researchers represent a critical network of support, especially on the topic of treaty design. This article outlines a research agenda focused on the new treaty as part of a larger ‘regime complex,’ where the interfaces between the new treaty and existing agreements will strongly shape its efficacy, efficiency, and acceptance by states. It also begins to pursue this research agenda, by investigating the relationship between the ocean governance regime, especially the United Nations Convention on the Law of the Sea, and the emerging plastics treaty. The article illustrates that the ocean governance regime offers important normative foundations, institutional models, lessons about treaty language, and possibilities for institutional linkage that can inform the design of the plastics treaty. It concludes by identifying several other avenues of useful research on the nascent plastics regime complex.
Research on anti-plastics activism in Indonesia and Malaysia, although increasing somewhat in recent years, is sparse and patchy. Interviews with local activists and a review of the existing literature, however, does suggest this activism is intensifying. Activists are educating people of the health and ecological risks of plastics, and operating nonprofit organizations to recycle and repurpose plastics. They are organizing cleanups and advocating for marginalized waste workers. And they are lobbying governments for stricter regulations, exposing illegal operations, and building transnational advocacy networks. Collectively, these strands of activism appear to have the potential to aggregate eco-actions and decrease plastic pollution. In the coming years, however, given the power of the global plastics industry and the nature of politics within Indonesia and Malaysia, pro-plastics corporations and industry allies are likely going to increasingly contest anti-plastics narratives and strive to undermine efforts to address the root causes of plastic pollution, including rising sales of single-use plastics by transnational corporations, the dumping and burning of unrecyclable plastics from high-income countries, and inadequate waste infrastructure and regulatory enforcement. Further research on how this politics is affecting the power and effectiveness of anti-plastics activism, the article concludes, is going to be essential for improving plastics governance.
Marine plastic pollution (MPP) has become ubiquitous in the oceans and is damaging human health, ecosystems, and economies which has resulted in a mandate for a new binding plastics treaty. What would an effective treaty look like? What explains this relatively new global crisis? This review article argues that the work of Karl Polanyi and stage theory can put the MPP problem into context and illuminate requirements of an effective treaty. Polanyi argued that if market society did not restrain the capitalist use of land (nature), labor, and money it would destroy itself and MPP will only be solved if these social and environmental protections restrain capital. Stage theory looks at the evolving expressions of capitalism in distinct historical periods to provide context for the global economy and implies a structural remedy for the plastics in the ocean. In particular, the post-War Fordist stage introducing mass production and the following post-Fordist neoliberal period witnessed progressively thinned restraints on capital and the global plastic flow is a function of these changes over time resulting in continuously increasing MPP.
Microplastics are ubiquitous in our environment but their presence in air is less well understood. Homes are likely a key source of airborne microplastics and microfibres to the environment owing to the frequent use and storage of plastics and textiles within them. Studying their presence, concentration and distribution in these environments is difficult without the participation of citizens due to accessibility challenges. Few studies have examined the intricacies of the prevalence of indoor microplastics and microfibres or the link between indoor exposure and behavioural and regulatory approaches that could reduce their concentrations. The application of a quintuple innovation helix framework, within which a co-creative citizen science research methodology is applied, provides an opportunity for citizens to shape the scientific method, ensuring that methods are accessible and appropriate for widespread use and designed by the citizen, for the citizen. Exploring behaviours and motivations in plastic and textile use by citizens with industry may reduce the generation of these particles. Future studies should consider the importance of citizen inclusion when designing research strategies for measuring and reducing microplastic concentrations in homes, enabling a nuanced understanding of their generation and distribution and facilitating the development of appropriate behavioural, industrial and regulatory messaging and mitigative measures.
Although studies suggest that wastewater treatment plants (WWTPs) are the main pathway for plastics into receiving waters, studies on the origin and fate of plastics entering WWTPs are imprecise and largely unexplored. The analysis of plastics in samples from WWTPs is also a relatively young and growing field compared with the marine environment. Furthermore, recent studies have shown that plastics are not uniformly distributed in WWTPs due to environmental factors and the inherent properties of plastics. Accordingly, this review article attempts to describe the current state of knowledge on plastic pollution in WWTPs and identify future research areas. In particular, this study describes the sources of plastics entering WWTPs and the analytical techniques used for the occurrence and properties of plastics in WWTPs. It also defines the role of these plastics as a possible source of microplastics and discusses the problems they can cause in WWTPs. The factors that can influence the variations in the number of plastics are defined. Furthermore, the policy needs for managing plastic pollution as a contribution to achieving the United Nations Sustainable Development Goals are assessed.
