Littering in urban areas poses a serious threat across the globe, with direct consequences on human health and climate change. Litter pieces such as soda cans or plastic bags left in the environment destroy nature by, for example, polluting water or contaminating soil. Moreover, animals consume these non-digestible pieces. Once they are washed away into the ocean, both land animals and fish ingest plastic pieces. Not only does this destroy the biodiversity, but toxic microplastics make their entrance in the human food chain as well. In light of these problems, there is a need for a rapid and flexible litter cleanup system.
