According to Henrik Beha Pedersen, founder of the organisation Plastic Change, there will be more plastics than fish in the oceans by 2050, because we let huge amounts of plastics out to the environment through different sources. This is a critical situation that deserves more attention on a global level. Not only because plastics are a huge danger to the marine environment, but also because studies have shown small fragments of plastics, so called “microplastics”, in marine animals throughout the food chain. This means that we can be exposed to microplastics through our food, and as plastics are accused for its endocrine disruptors, we shouldn’t have to argue that it doesn’t belong in us. One of many sources to the outlet of microplastics is sewage from households and industry, which along with rainwater ends up on a sewage treatment plant. In Denmark we don’t have a “plastic policy” , and some of the microplastic particles in sewage are therefore let directly out into the environment. Earlier this year, KD Group tried out a new-developed membrane filter on Vejle Spildevand in Denmark, in the attempt to hold back some of the microplastics in the sewage. In this paper we will study the membrane filter technology and how it is possible to implement this technology to the danish sewage treatment systems, as one way of reducing the outlet of microplastics to the environment.
