SCIENCE TO SOLUTIONS

Science has always been the cornerstone of 5 Gyres’ work, informing our solutions, strategies, and focus. We conduct primary research to better understand the global impact of plastic pollution and to vet alternatives to petroleum-based plastics. Our research projects are collaborative, inviting other global scientists, thought leaders, and industry experts to partner with us, ensuring that we are asking and answering the right questions.

THE SECTOR FRAMEWORK

Our 10+ years of research on ocean and terrestrial plastics leads us to focus on understanding specific sources, or sectors, that generate plastic pollution, in order to create more effective solutions. There are many unique sources of plastic pollution — such as microfibers from textiles, microplastics from agricultural practices, floating ocean plastics from fishing gear, and everyday single-use packaging — and solutions for each of these require specific designs, policy approaches, and innovation. 5 Gyres is focusing much of our current research on microfibers & textiles.

Current Science Projects

Our published research is the result of months, and sometimes years, of behind-the-scenes work for each study. Here is a preview of some current scientific projects and research that will be published in the future. Be the first to know about new scientific developments by subscribing to our newsletter!

PLASTIC AIR

Quantifying sources of microfiber pollution & vetting solutions

We know that laundering our clothing contaminates the air we breathe with plastic microfibers, but we know very little about the scale of this contamination. We’re studying microfiber emissions from commercial laundry facilities in San Francisco to better understand microfiber sources and identify solutions.

PLASTIC CARPETS

Investigating a lesser-known source of microfiber pollution

While microplastic pollution from clothing has garnered increasing attention, other textiles, such as carpets and other upholstery, remain a largely overlooked source of synthetic fiber emissions to both air and water. This study explores the magnitude, characteristics, and pathways of microfiber release from various carpet types in indoor environments. 

BETTER ALTERNATIVES

Vetting alternative materials to conventional plastics

Building on 5 Gyres’ Better Alternatives series, this project will test market ready, off-the-shelf products from different sectors, including single-use products and packaging, fishing gear, personal care products, agricultural products, and smoking materials, to investigate fragmentation and biodegradation.

FLOATING WETLANDS

Exploring nature-based solutions for microplastic capture

Coastal areas and nearshore tidal zones represent critical spaces where urban pollution, including microplastics and other contaminants, enters marine ecosystems. Floating wetlands have emerged as a promising, low-tech, nature-based solution to improve water quality and support biodiversity. This field study will provide data on a nature-based filtration solution for microplastics and heavy metals.
