We leverage our expertise and network of strategic partners to develop insights and tools that help identify gaps to solving the plastic pollution problem, prioritize strategies, set baselines and targets, and measure the success of solutions.


Our relationships from across industries and geographies allows us to form a unique viewpoint on the implementation of inclusive and effective solutions on the ground and to amplify what works so stakeholders can make better decisions about engaging in the sector.



The Circulate Initiative, together with Circulate Capital and Singapore's Agency for Science, Technology and Research (A*STAR), has developed an open-sourced prototype greenhouse gas calculator to track the environmental impact of plastic waste management and recycling solutions that prevent plastic pollution in India and Indonesia.

PLACES - Plastic Lifecycle Assessment Calculator for the Environment and Society - measures the environmental benefits of an investment through carbon footprint, and energy and water consumption.

The TCI Knowledge Bank

The Circulate Initiative's Knowledge Bank encompasses research, resources and tools focused on solutions to address ocean plastics and measures of impact.


With this set of resources, we aim to inform the overall discussion on ocean plastic by ensuring the global and public narrative on ocean plastic is informed by science and practice and focuses on tangible solutions, including the importance of circular waste management and recycling.

Impact Metrics Working Group

To better understand the impact of solutions to address plastic leakage, The Circulate Initiative convened a diverse group of subject matter experts in an Impact Metrics Working Group that can identify and address key gaps in data, metrics and methods.

Members include the world’s foremost experts on waste management and ocean health, investors, NGOs, researchers, and advocacy organizations.

With the Impact Metrics Working Group, The Circulate Initiative developed its first research agenda to provide analysis and interpretation of emerging topics and help stakeholders navigate toward the most effective solutions. The Impact Metrics Working Group provides input and guidance into key reports and resources being explored by The Circulate Initiative.
