Background

By implementing previously unutilized resources the WAB project (Wetlands, Algae, Biogas, a South Baltic Sea Eutrophication Counteract Project) can create sustainable solutions that benefit the marine and land environment, reduce eutrophication and produce biogas.

The WAB project will collect coastal algae, that are produced as a result of nutrient leakage, as well as vegetation from constructed wetlands and use them both as additional biomass for biogas production.
By doing this the WAB project has the ability to remove nutrients from the highly eutrophied Baltic Sea in an economically efficient and holistic process that could result in a required reversal of nutrient flows.

WAB is a project of the South Baltic INTERREG Programme made up of 11 cooperating partners in Sweden and Poland. The core areas for testing and implementation are Trelleborg in Sweden and Sopot in Poland.

WAB is a project that can deliver economically as well as environmentally useful solutions. For example, the produced biogas would directly benefit the environment and reduce dependency on other energy sources, therefore reducing costs.

This high level of wide-ranging success further elevates WAB's potential, and once implemented the principles of WAB can be transferred to other locations around the Baltic Sea that are experiencing similar issues with excess algae growth, eutrophication and lost tourism revenue.

In short, the project offers an innovative holistic approach by constructing a cycle previously unseen in the Baltic Sea. The project has the potential to spread the findings throughout the South Baltic Region which would bring environmental, social and economical benefits to the area.
