The 5 Gyres Institute is a nonprofit based in Santa Monica, California, that researches plastic pollution in the world’s oceans and seeks to drive systemic change. In 2011 it completed the first global survey of plastic marine pollution, documenting plastic across all five subtropical gyres, the major ocean current systems where debris accumulates. The organization highlights how plastic waste affects ecosystems, wildlife, and human health through the introduction of toxic chemicals into the food chain. It blends scientific research with outreach to corporate partners, policymakers, and the public to reduce plastic pollution. It operates as a small to mid-sized nonprofit. In 2025, Grove Collaborative partnered with 5 Gyres Institute, reflecting ongoing collaboration with diverse partners to advance its mission.
