Fighting for Trash Free Seas®

Ending the flow of trash at the source


Current efforts to eliminate ocean trash are not enough.

Ocean Conservancy has mobilized millions of people around the world to remove trash from our ocean and waterways. But removal is just one part of the solution. We must also prevent trash from reaching our waterways and the ocean in the first place, which is why in 2012 Ocean Conservancy launched the Trash Free Seas Alliance® (TFSA). TFSA unites industry, science and conservation leaders who share a common goal for a healthy ocean free of trash, and plastic pollution.


Ocean plastic pollution is a massive problem on a global scale.

The Trash Free Seas Alliance® is the oldest forum of its kind focused on innovative and pragmatic solutions to rid the ocean of plastic pollution and other forms of marine debris. Through the Trash Free Seas Alliance®, corporate members have collectively committed millions of dollars for research on ways to improve waste collection and recycling in parts of the world most impacted by ocean plastic pollution. Conservation members provide insights via research, policy recommendations and collaboration across individual initiatives. Many of the members also support Circulate Capital and The Circulate Initiative, the investment management firms created in partnership with Ocean Conservancy and Closed Loop Partners dedicated to financing companies, projects and infrastructure to prevent ocean plastic pollution.

TFSA members have also pledged to eliminate or replace up to half a million tons of virgin plastic from products and packaging each year. See current TFSA members.

The goal: real-world collaboration to stop the flow of plastics into the ocean.

You can help.

Signature Initiatives

Stemming the Tide: Land-based strategies for a plastic-free ocean (2015)

StemmingTheTide_TFS_ThumbnailThis report helped us understand how and why plastic waste is leaking into the ocean and evaluate potential prevention approaches. It found that 75% of plastic entering the ocean was never collected to begin with and that low-value plastics were most likely to enter the ocean.

The Next Wave: Investment Strategies for Plastic Free Seas (2017)

TheNextWave_TFS_ThumbnailThis report helped us understand how to systematically break down the barriers to effective waste management that will ultimately stem the flow of plastic waste into the ocean. It highlighted that most waste management systems operate at a net cost and that to improve waste collection the economics of these systems will need to change.

Circulate Capital (2018)

CirculateCapital_TFS_ThumbnailArmed with the knowledge of the financing gap for waste management, Ocean Conservancy and the Trash Free Seas Alliance worked to design and launch Circulate Capital. This collective effort aims to:

  • Build an investment pool and funding mechanism;
  • Advocate governments to prioritize waste management; and
  • Test business models in high leakage cities.
Plastics Policy Playbook (2019)

PlasticsPlaybook_TFS_ThumbnailInvesting in waste management is critical; however, additional measures will be needed. The Plastics Policy Playbook identified four key themes to improve the economics of collection across the value chain:

  • Financing the collection via Extended Producer Responsibility measures;
  • Reducing the production and use of problematic single-use plastics;
  • Designing for circularity, and
  • Increasing the demand for post-consumer plastics.

The Playbook also identified engagement and inclusion of the informal sector as one of the key principles for success.

In 2020, the Trash Free Seas Alliance will work with its members and Steering Committee to design its next Signature Initiative aimed at initiatives focused on the inclusion of the informal sector.


TFSA Technical Advisors

Dr. Kara Lavender Law

TFSATechnicalAdvisors_Kara_Lavendar LawDr. Kara Lavender Law is a Research Professor of Oceanography at Sea Education Association (SEA; Woods Hole, Massachussetts), studying the sources, distribution, transformation and fate of plastic debris in the ocean. Trained as a physical oceanographer, Dr. Law has more than 12 months of sea time on oceanographic and sailing research vessels, including in the eastern North Pacific and western North Atlantic Oceans where plastic debris accumulates in regions dubbed, “garbage patches”.  Dr. Law’s current research interests focus on the sources of plastic to the marine environment, understanding how ocean physics determines the distribution of plastic and other marine debris, and the degradation and ultimate fate of different plastic materials in the ocean.  She is co-chair of the Scientific Committee on Oceanic Research (SCOR) Working Group Floating Litter and its Oceanic TranSport Analysis and Modelling (FLOTSAM), and serves as the co-principal investigator of the Marine Debris Working Group at the National Center for Ecological Analysis and Synthesis (NCEAS). Dr. Law holds a PhD in physical oceanography from Scripps Institution of Oceanography and a BS in mathematics from Duke University.

Dr. Chelsea Rochman

TFSATechnicalAdvisors_Chelsea_RochmanChelsea Rochman is an Assistant Professor in Ecology at the University of Toronto and a scientific advisor to Ocean Conservancy. Chelsea received her PhD in Ecology from a joint program between University of California, Davis and San Diego State University in 2013. She then was a Smith Postdoctoral Fellow in Conservation Biology. She was hired as an Assistant Professor at the University of Toronto in the Department of Ecology and Evolutionary Biology in 2016. Chelsea has been researching the sources, sinks and ecological implications of plastic debris in marine and freshwater habitats for more than a decade. She has published dozens of scientific papers in respected journals and has led international working groups about plastic pollution. In addition to her research, Chelsea works to translate her science beyond academia. For example, Chelsea presented her work to the United Nations General Assembly and at the U.S. Department of State.
