Science
as a compass

back on 2024

Surfrider Foundation Europe has been working to protect the ocean for over 30 years. Every year, thousands of citizens, associations, businesses and scientists participate in collecting data on aquatic waste, providing a better understanding of its origin and impact.
In 2024, Surfrider conducted several scientific and participatory science programmes that analysed the quantity, nature and distribution of waste found on beaches and riverbanks in Europe.

Ocean initiatives

Ocean Initiatives enable anyone to collect and quantify 30 types of waste.

Biomedias

The Biomedia project involves collecting opportunistic data on the presence and type of biomedia.

OSPAR/MSFD

The Ospar/MSFD protocols monitor 100-metre sites each season with a detailed classification of 251 categories of waste on beaches and rivers.

OSPARITO

Osparito, a version of the OSPAR/MSFD protocol designed for primary school children/leisure centres.

Plastic origins

Plastic Origins collects data on waste in rivers.

All of the data is used at different levels – local, national and European – to improve scientific knowledge on the subject. This information is also used by advocacy teams to influence policy makers and challenge industry players to take direct action at the source of pollution and promote stricter environmental regulations.
This report highlights the results of these actions and emphasises the importance of collective commitment.

Everyone, at their own level, can contribute to preserving the environment and the ocean.

Biomedias

Plastic objects used as a substrate for bacteria to break down organic matter in wastewater treatment processes.

During floods, intense storms, busy tourist periods generating significant water flows, or infrastructure malfunctions, biomedia can be discharged into the environment.

Industrial plastic pellets

Raw material enabling manufacturers to produce plastic objects.

Pollution can occur during the handling of industrial plastic pellets (IPP), transport (by sea and land) or storage.
Wind and rain then contribute to their dispersion, as they are very light.
