Microplastics: What to Know
Microplastics: What to Know
Working Together for Science-Based Solutions
OUR COMMITMENT
Microplastic pollution is a complex global challenge. We’re committed to advancing science, improving recycling, and driving innovation to reduce plastic waste and prevent microplastics from entering the environment. Through targeted investments and cross-sector collaboration, we’re working to deliver real solutions that mitigate pollution while preserving the essential benefits of plastics.
Our Approach
INNOVATING FOR IMPACT
We’re advancing a circular economy—keeping plastics in use and out of the environment, so they don’t break down into microplastics.
- Designing for reuse and recycling
- Build better recycling systems
SUPPORTING SMART POLICY
We support advancing practical evidence-based solutions that address the real sources of microplastic pollution—through improved recycling, advanced product design, and effective waste management systems, among other solutions. These science-based measures encourage innovation, provide regulatory clarity, and deliver measurable environmental benefits. While blanket bans may seem effective, they often miss the mark.
Focus on measurable outcomes
Differentiate microplastic types
Encourage R&D and investment
Avoid symbolic bans
ADVANCING THE SCIENCE
The global chemical and plastics industry has supported over 100 researchers across the globe that has already resulted in papers published in peer-reviewed journals, with many more anticipated in the coming years.
STEWARDSHIP IN ACTION
Preventing pellet loss with real accountability.
FREQUENTLY ASKED QUESTIONS ABOUT MICROPLASTICS
What are microplastics and how do they form?
Microplastics are tiny plastic particles—typically less than 5 millimeters in size—that can result from the breakdown of larger plastic products over time or be intentionally added to products for specific functions. They can form through wear, use, and improper disposal, which is why reducing waste and improving recovery systems is critical.
What is the plastics industry doing to address microplastics?
Our industry is investing in innovations that reduce the potential for plastics to enter the environment. We’re designing products for reuse and recyclability, expanding recycling infrastructure, and supporting cutting-edge research. We’re also collaborating with scientists, governments, and businesses to unlock targeted, science-based solutions to address microplastic pollution.
How can innovation help reduce microplastics?
Innovations in product design and recycling technologies are making it easier to reuse and remanufacture plastics. A circular economy—where plastic is collected at end of life and remade into new products rather than discarded—means less plastic waste overall, and over time, fewer microplastics generated. Advanced recycling technologies also help conserve natural resources and reduce the environmental footprint of plastic.
Is the plastics industry investing in scientific research on microplastics?
Yes. Globally, our industry has supported over 100 researchers across 37 institutions to advance the science on microplastics. We’re investing in research related to microplastics behavior in the environment, potential health impacts, and the development of standardized testing methods. Through the Microplastics Advanced Research and Innovation Initiative (MARII) platform, we facilitate global collaboration to enhance research quality and consistency.
Do microplastics pose a risk to human health?
To date, leading health authorities—including the FDA and WHO—have found that while the current scientific data is of poor quality, the current weight of evidence does not show microplastics pose a risk to human health. While ongoing, high-quality research is improving our understanding of microplastics, science and innovation, not speculation—should guide how we address this complex issue.
What kinds of policies does the industry support to address microplastics?
We support science-based policies that:
Target solutions based on a real assessment of risks, which includes understanding both hazard and exposure.
Encourage innovation, including R&D and advanced recycling.
Foster public-private partnerships.
Provide regulatory certainty for investment.
Recognize distinctions between intentionally added and unintentionally generated microplastics.
We also support consistent international standards and oppose fragmented or symbolic policies that create inefficiencies and raise costs without measurable impact.
Does the industry support bans on microplastics?
We believe blanket bans or symbolic caps often miss the mark. Instead, we support targeted, fact-based interventions—like improved wastewater treatment and enhanced recycling systems—that are more likely to reduce environmental impact. It’s also important to differentiate between types of microplastics. For example, some intentionally added microplastics serve critical purposes, such as slow-release fertilizers or crop protection.
What is Operation Clean Sweep® and how does it help prevent microplastics?
Operation Clean Sweep® (OCS) is an industry-led stewardship program designed to help prevent plastic resin loss during manufacturing and transport. Active in more than 60 countries, OCS provides guidelines and accountability tools to help companies achieve zero pellet loss. In the U.S., members are required to report data quarterly and undergo third-party verification under OCS Blue and OCS Logistics programs.
Why should the public trust industry-led initiatives like Operation Clean Sweep?
Operation Clean Sweep isn’t just voluntary guidance—it now includes mandatory reporting and third-party verification for U.S. members. These accountability measures reflect our commitment to continuous improvement and transparency. The program spans the entire value chain, bringing together producers, shippers, and converters to prevent plastic pellet loss at every step.
How do plastics relate to affordability and everyday life?
Plastics play a critical role in making modern life more affordable and sustainable—from reducing food waste and delivering clean water to enabling life-saving medical devices and energy-efficient building materials. Policies addressing microplastics must take these societal benefits into account and avoid unintended economic, environmental, or human health consequences.
