Researching urban runoff management advances sustainable urbanization
Rainwater or meltwater that runs unrestrainedly down the streets is a major problem for a city. Urban runoff water that is unfiltered carries the dirt and pollutants of the streets with it, thus it also causes environmental burden. Natural solutions for urban runoff management are essential elements of the future’s city. However, the solutions will not be possible to develop without thorough scientific research.
Green infrastructure helps control the environmental problems of the cities
The greenhouse gases emitted in cities hasten climate change and deteriorate citizens’ wellbeing. There are challenges in sustainable urbanization but the ways for achieving carbon neutral cities are already within reach. Long Xie, our researcher, tells how green infrastructure can boost the development of cities.
Companies have the possibility and the responsibility to uphold biodiversity
Companies have benefited greatly from nature and now the time has come for companies to help nature in return. The societal progression that has had the biggest effect on biodiversity has been the increase in consumption . Now is the time to wake up and realise that companies’ actions are greatly needed. Companies have a multitude of possibilities to guard nature values more effectively. Switching to circular economy solutions in manufacturing goods and services, and demanding ecological actions from cooperation partners, to name but a few. The biodiversity catastrophe we are undergoing is possible to tackle but it requires cooperation and genuine contributions.
Could the green wall filter microplastics from urban runoff?
InnoGreen is currently examining how effectively microplastics can be filtered from urban runoff by directing the runoff water through a green wall. For research purposes a modular green wall was built in Konala, Helsinki. The runoff water from Kehä 1 ring road is directed into the green wall. The study is one of the Speedy Experiments of the Baltic Sea Challenge.
