954 000 tons of fish byproducts is produced annually by Norwegian processing plants alone. As a resource it is plentiful and its ongoing. This diploma project is an exploration of the potential within the marine waste streams. The Norwegian Government has set a national strategy to increase utilization and value creation of marine residual raw materials, in order to reach the United Nations goal of a circular economy. Through a multi-disciplinary design approach, this diploma project suggests two design proposals to support this strategy. Working collaboratively with relevant actors, I have mapped out necessary steps in order to expand the industry of fish byproducts. It is meant to serve as a holistic overview, to better understand the steps needed to achieve the Government’s vision. To contribute to this vision, I have explored the inherent potential of fish byproducts to develop an alternative to plastic. In order to illustrate this development, I have designed alternative uses to serve as opportunity areas, with the aim to inspire further research. In addition, I hope to inspire a shift in the perceived value of fish byproducts: from waste to resource. My main ambition for this project is to stimulate the development of wholesome raw material utilization, as well as contribute to the vision of a circular economy.
