MARII Summit on Microplastics | Madrid, Spain | 15-17 October 2025

The Microplastics Advanced Research & Innovation Initiative (MARII) Summit, held during October 2025 in Madrid, convened experts from academia, government, industry, and research institutions to advance microplastics science.

Here you’ll find the presentations from the Summit. These materials are intended to support researchers, regulators, and partners working to close data gaps, strengthen methods, and seek collaborations to further the science of microplastics.
