Baltic Beach Wrack

Project: CONTRA – Baltic Beach Wrack – COnversion of a Nuisance To a Resource and Asset

The CONTRA project compiles the knowledge required for sustainable management of beach wrack in the Baltic Sea Region and carries out case studies for beach wrack treatment.

More about the project

Beach wrack is organic material washed ashore, e.g. torn off sea grass or brown algae. The Beach wrack that has great involvement of eelgrass can have a significant increase in the heavy metal content. It can cover Baltic Sea beaches for weeks after storms, rotting into a smelly soup and leaking nutrients back into the water. Managing beach wrack is an issue for local authorities and the tourism industry, in particular of the western and southern Baltic Sea.

Beach wrack is often regarded as a nuisance, particularly when it lands unexpectedly and in large quantities on tourist beaches. Local authorities have to pay a lot of money to collect and dispose of it. The challenge is to find a balance between public demand for ‘clean’ beaches, environmental protection and the economy.


  • Test and propose utilization/recycling options that are sustainable & economically viable
  • Investigate and define value chains, market opportunities & legal frameworks for wrack based products.
  • Analyze its recycling potential for pollution & nutrient remediation • Improve knowledge about the role & importance of beach wrack
  • Raise awareness about the impact of beach cleaning operations
  • Reduce the costs of problematic beach wrack for local authorities

The project is part of the research in the research group The Environmental Science and Engineering Group (ESEG)
