Studenteropgave: Basisprojekt


This paper sets out to determine how plastic waste travels in the harbor of Copenhagen, in order to limit the emission of it, and to find out if it ends up at the designated municipal waste collection locations. Certain stakeholders are consulted concerning plastic in the harbor and in general. Furthermore, local current patterns are outlined, to determine what might happen to plastic that leaves the harbor. To track the movement of plastic waste, an artifact is constructed by vacuum packing a cellular phone, along with pieces of polyurethane for buoyancy. The phone is equipped with an app, which draws a map of the traveled route. The design of the artefact is made according to the principals of Soft Design Science Methodology and Donald Schön’s Reflective Practitioner. Several experiments are then conducted, following an experiment protocol, on various locations around the harbor. A number of weather conditions that might influence the movement of the artifact are noted at the start and end of each experiment. During the experiments observations in the harbor are made. The performed experiments seem to show, that the collection locations are largely missed by the plastic waste, and that the plastic, under the right conditions, might travel out of the harbor area faster than it can be collected. It is however concluded that the data from the experiments are too insufficient to establish anything for certain.
