Microplastics: A Review of Policies and Responses
AI summary Read the abstract
This critical review assembled current knowledge on policies and regulatory responses to plastic pollution globally, including legislative measures, economic instruments, and voluntary commitments. The authors identify a gap between scientific evidence and policy action and call for stronger, more coordinated international governance of plastic pollution.
Although (micro)plastic contamination is a worldwide concern, most scientific literature only restates that issue rather than presenting strategies to cope with it. This critical review assembles the current knowledge on policies and responses to tackle plastic pollution, including peer-reviewed scientific literature, gray literature and relevant reports to provide: (1) a timeline of policies directly or indirectly addressing microplastics; (2) the most up-to-date upstream responses to prevent microplastics pollution, such as circular economy, behavioral change, development of bio-based polymers and market-based instruments as well as source-specific strategies, focusing on the clothing industry, tire and road wear particles, antifouling paints and recreational activities; (3) a set of downstream responses tackling microplastics, such as waste to energy, degradation, water treatment plants and litter clean-up strategies; and examples of (4) multifaceted responses focused on both mitigating and preventing microplastics pollution, e.g., approaches implemented in fisheries and aquaculture facilities. Preventive strategies and multifaceted responses are postulated as pivotal to handling the exacerbated release of microplastics in the environment, while downstream responses stand out as auxiliary strategies to the chief upstream responses. The information gathered here bridges the knowledge gaps on (micro)plastic pollution by providing a synthesized baseline material for further studies addressing this environmental issue.

Regulatory Approaches to Plastic Mitigation
AI summary Read the abstract
This chapter reviews existing research and policies on plastic pollution, including microplastics, at local, national, and global levels. It examines rules targeting single-use plastics and waste management, finding gaps in how these policies are put into practice and enforced, and calls for stronger coordinated legislative action.
Policy priorities: emerging trends in a global response
AI summary Read the abstract
This policy review examines global regulatory responses to plastic and microplastic pollution, identifying focal areas, gaps, and future directions by drawing parallels to historical policy development around air pollution management.
The Role of Legislation, Regulatory Initiatives and Guidelines on the Control of Plastic Pollution
AI summary Read the abstract
This review examines existing plastic pollution regulations globally, finding that despite many proposals and national bans, the overall effectiveness of legislation is unclear and most measures focus narrowly on marine plastics or single-use items. The authors argue that laws often lag behind science and face practical limitations given how deeply embedded plastics are in daily life.
The Burden of Microplastics Pollution and Contending Policies and Regulations
AI summary Read the abstract
This review examines the growing global burden of microplastic pollution and the policies being developed to address it. Researchers found that inadequate waste management systems allow massive amounts of plastic to contaminate terrestrial and aquatic environments, threatening ecosystems and the billions of people who depend on them. The study evaluates existing regulations and suggests that stronger, more coordinated policy frameworks are needed to curb microplastic pollution.
Governance Strategies for Mitigating Microplastic Pollution in the Marine Environment: A Review
AI summary Read the abstract
This review assessed the sources, spread, and impacts of microplastic pollution in marine environments and evaluated existing governance strategies for addressing the problem. Researchers found significant gaps in management approaches, including limited community involvement in monitoring and a lack of standardized mitigation strategies for coastal areas. The study calls for stronger policy interventions, more citizen science initiatives, and coordinated international efforts to reduce microplastic pollution in the oceans.
