Who We Are

The Circulate Initiative is a non-profit organization established in 2018 to solve the ocean plastic pollution challenge and build circular and equitable economies across emerging markets.

Our Story

An estimated 140 million tonnes of plastic waste has accumulated in the world’s oceans and rivers. In the absence of needed interventions, plastic waste entering the ocean annually could nearly triple by 2040, reaching 29 million tonnes.  However, research shows that an 80% reduction of ocean plastic leakage is possible by 2040 through the use of existing technologies if we combine upstream and downstream solutions to achieve system change.


Early market research by investment firm Circulate Capital also highlighted the need to improve access to the right tools and knowledge to guide decision-making and investment in waste management and plastic recycling, and to strengthen the pipeline of investment-ready solutions. Recognizing that no entrepreneur succeeds in a vacuum, the research also pointed to the need to ensure enabling conditions - including public policies, corporate commitments, consumer engagement and strong science and data - are in place.

Established in 2018 with the support of Circulate Capital, The Circulate Initiative is working to fill these market gaps and address systemic barriers in the plastics circular economy.


The Circulate Initiative is a U.S.-registered 501(c)(3) organization.


Our Approach

We believe that preventing plastic waste leakage into the ocean and advancing circularity across South and Southeast Asia require a focused and systemic response. 


The Circulate Initiative delivers cutting-edge research and builds high-impact programs and partnerships to address system-level barriers in the circular economy and drive collective action with corporations, investors and policymakers.

2022 Annual Report

2022 marked a year of milestones and achievements for The Circulate Initiative, building on our momentum to develop new research and tools, and scale programs focused on addressing the ocean plastic pollution challenge.


Working closely with our partners, we provided greater transparency on the financing of the plastics circular economy, facilitated better understanding of local recycling supply chains and advanced efforts to embed inclusivity within the ecosystem.
