In the future, green solutions will likely take an important role in the prevention of microplastics in the Baltic Sea. The Baltic Sea Challenge pilot project tests green walls as a means for collecting microplastics in stormwater, preventing them from contaminating water systems.
In cooperation with Baltic Sea Challenge’s series of the speedy experiments, InnoGreen has set up a green wall in the Helsinki district of Konala to test how vehicle tyre residue can be effectively filtered from stormwater before it reaches the Baltic Sea.
The Baltic Sea Challenge, which coordinates the Baltic Sea protection efforts in Helsinki, has initiated four agile trials to find ways to curb the accumulation of marine litter in the important waterway. One of the companies selected for the trials is InnoGreen, which aims to test the capability of a green wall in reducing the amount of microplastics carried out to the sea by stormwater.
“Improving the state of the fragile Baltic Sea is an important goal for Helsinki. Alongside eutrophication, the accumulation of plastic waste is extremely harmful to marine ecosystems. Helsinki is encouraging a variety of operators to look for new ways of preventing plastic waste by funding a variety of trials. We hope to learn a lot and find efficient methods for the prevention of marine litter,” says Helsinki’s Deputy Mayor Anni Sinnemäki.
Testing the efficacy of a green wall in collecting microplastics
A modular green wall through which runoff from the Ring I road flows has been built in the underpass by the Mätäjoki River. The pilot study will examine the efficacy of the green wall structure in filtering microplastics from stormwater and preventing the plastic particles from entering water systems.
“InnoGreen is happy to be involved in the Baltic Sea challenge. We want to create green solutions that improve the quality of life of city residents. By studying the filtration of microplastics and other impurities, we can gain valuable information to aid the development of green solutions for tackling environmental challenges,” says InnoGreen’s Mats Wikström.
In the sea, microplastics are ingested and accumulated by a variety of organisms, such as shellfish and fish. Urbanisation increases the emissions caused by traffic, which is why we need new ways to prevent plastic waste from contaminating the environment.
