You found the Wooden Brick!
Please report the number and location where you found it.
Help us gather valuable data.
Catch and release:
After registrering, you are welcome to release the wooden brick into the water again.
Wooden Bricks will be released
The releases will occur in two phases: November 2024 (during the rainy season) and summer 2025, with 10,000 bricks released at 24 locations in the waterways of Lemvig and Varde, Denmark. All found and registered bricks will be mapped to track and understand their movement.
Research and Innovation
The aim of releasing wooden bricks into the water is to gain insights into how plastic objects and other waste move through our rivers, streams, creeks, and fjords to the ocean, allowing us to identify critical hotspots for targeted intervention.

Our Mission
Every year, at least 14 million tons of plastic end up in the ocean, and plastic makes up 80% of all marine debris found from surface waters to deep-sea sediments. We're here to stop it.
An EU Initiative to Prevent Plastic Pollution from Reaching the Ocean
TREASURE is an EU collaboration involving Denmark, France, Belgium, the Netherlands, and Germany, aimed at mapping plastic pollution, specifically macroplastic (plastic pieces larger than 0.5 cm), in rivers, streams, creeks, and fjords to prevent it from flowing into the ocean. Lemvig Vand and KIMO Denmark are leading the plastic program of TREASURE in Denmark.

Planned Initiatives & Projects
Living lab experimenting (2023-2026)
We are conducting real-life experiments in the danish living lab: West Coast Watersheds in Lemvig and Varde to test solutions and monitor plastic pollution. Collaborating with four other living labs in the North Sea region—France, Belgium, the Netherlands, and Germany—we exchange knowledge and validate our results.
Data collection efforts (2024-2026)
Denmark’s TREASURE project tracks plastic pollution in aquatic environments by identifying key sources and hotspots. The Wooden Drifter Experiment releases wooden bricks into waterways to simulate waste movement, helping to pinpoint accumulation zones and potential outflows to the sea. This data is crucial for preventing further plastic pollution in our waters.
Prevention & Behaviour change (2024-2027)
Preventing plastic pollution is more effective than removing it. This initiative focuses on involvement and education regarding plastic pollution, its sources, consequences, and solutions. The Wooden Brick Campaign serves as a citizen science project, engaging many schools to educate students aged 6 to 19 through school activities.
Establish removal systems (2025-2027)
This initiative aims to deploy advanced technologies designed to capture plastic pollution in waterways. Removal systems will be strategically installed at identified hotspots in Lemvig and Varde Municipality and thoroughly tested to evaluate their effectiveness in reducing plastic waste.
National Plastic Pact (2025-2030)
To effectively combat macroplastic pollution, collaboration among municipalities, utility companies, NGOs, politicians, and civil society is essential. A unified national approach to governance and policy is crucial for effective management and lasting impact. Therefore, we will work towards establishing a National Plastic Pact.
