From personal mission to global movement

It started at her kitchen table.

How it started

In 2011, Maria Westerbos founded Plastic Soup Foundation at her kitchen table. What began as a personal mission has grown into one of the world’s leading organizations fighting plastic pollution.

Maria’s mission

Maria sounded the alarm on microplastics long before the world took notice. She combined science, awareness and activism. Under her leadership, PSF became a driving force behind research, campaigns and systemic change.

Science over sentiment

Science has always guided our work. PSF leads in research on micro- and nanoplastics and their health impact. We collaborate with top scientists worldwide and apply the precautionary principle: when there’s risk, we act.
