This study is part of the international project Circular Ocean and focuses on reducing marine plastic waste within the Northern Periphery and Arctic (NPA) region by developing new sustainable solutions for the reuse of discarded waste fishing nets. Recycled plastic fibres from waste fishing nets of high-density polyethylene (HDPE) were investigated with respect to their engineering properties such as tensile strength and Young’s modulus. Tensile tests were carried out on monofilament fibres from fishing nets in accordance with ASTM Standards and were performed on both new fibres and waste fibres from similar net types. Waste fishing nets of the type “Braided Polyethylene” were collected at the dump-site in Sisimiut, Greenland, and are produced by Euronete and supplied by Vónin, which is the leading supplier of fishing gear in Greenland. With this screening it is possible to evaluate the applicability of this type of discarded fishing nets as reinforcement in construction materials. The present paper focuses concrete materials and discusses how the fishing nets can be implemented in concrete in order to improve its properties.
