Clean Oceans International

Our Mission

Clean Oceans International (COI) is a California-based 501(c)(3) nonprofit working to reduce ocean plastic pollution through science, community engagement, and practical solutions.

Our work focuses on two complementary approaches:

Community Science & Data (EPAP) Through our Environmental Plastic Assessment Program (EPAP), we train volunteers, students, and partner organizations to measure plastic pollution on coastlines using standardized survey methods. This work generates consistent, comparable data that helps communities understand pollution trends, evaluate cleanup efforts, and advocate for informed solutions.

Developing Practical Waste Solutions (PPWC) COI is actively developing small-scale plastic waste conversion systems designed for communities with limited waste infrastructure. This work is currently in the research and development phase, with the goal of creating a safe, adaptable, and deployable system.

We are collaborating with partners in places such as Ulithi Atoll and Baghdad, where local teams are currently conducting plastic assessments and cleanups to better understand their waste streams and inform future system design and potential deployment.

From Data to Action COI connects field data with on-the-ground action—supporting coastal cleanups, long-term beach adoption efforts, and partnerships that turn information into impact. By combining measurement, education, and implementation, we help communities move from awareness to informed decision-making.
