This report is based on a series of unpublished national port-related feasibility studies focused on the collection and recycling of waste fishing nets and ropes (FNRs). The research was completed by Circular Ocean project partners in Greenland, Ireland, Norway and Scotland during 2016-17. This report includes an executive summary and then a review by each country of the key cross-cutting issues related to waste FNRs, port-related innovation systems and new opportunities.
