28.04.2022 – A recently conducted national study to assess waste along Swiss rivers and lakes found that the origin of waste is quite diversified: in some cases, waste is discarded directly at the given location; in other cases, the waste washes up on river banks or lake shores or is swept up by the wind or other weather conditions. More often than not, the waste is made of plastic. This study will serve as an important frame of reference for action plans to maintain and further enhance the environmental cleanliness of Swiss river and lake regions in the future.
