“…The variation in rope materials is an essential factor in deciding the fate of the rope at the EOL. The complexity of the design meant that segregation or pre-sorting is required to remove the metal and heavy fractions of rope parts to prevent damage to mechanical recycling unit blades (Stolte and Schneider, 2018;Deshpande et al, 2020a). The complex mixture of polymers and other metals may provide specific applications to the ropes; however, these mixed polymers result in operational challenges in recycling the ropes, reducing the feasibility of recycling operations (Stolte and Schneider, 2018).…”

The complex mixture of polymers and other metals may provide specific applications to the ropes; however, these mixed polymers result in operational challenges in recycling the ropes, reducing the feasibility of recycling operations (Stolte and Schneider, 2018). As a result, material composition and properties are crucial information that dictates the recyclability of ropes and associated technology for recycling (chemical or mechanical).…”

“…The main challenges for the circular fishing gear design are associated with the following: low utility of current materials, high level of mixing of different materials, lack of legal obligations for recycling from local authorities, lack of support and high cost of alternatives, low use of collection points in harbors and high organic contamination, which reduces the recyclability [79].…”

Properties and Recyclability of Abandoned Fishing Net-Based Plastic Debris

Plastics in marine environments undergo molecular degradation via biocatalytic and photocatalytic mechanisms. Abandoned, lost, or discarded fishing gear (ALDFG) damages marine and coastal environments as well as plant and animal species. This article reviews ghost fishing, ecological damage from marine plastics, recommended recycling practices and alternative usages of derelict fishing gear. Material mixing techniques are proposed to counteract the effect of biocatalytic and photocatalytic biodegradation within the context of plastic fish net recycling. There is a need for a new and rapid “multidimensional molecular characterization” technology to quantify, at a batch level, the extent of photocatalytic or biocatalytic degradation experienced on each recovered fishing net, comprising molecular weight alteration, chemical functional group polydispersity and contaminant presence. Rapid multidimensional molecular characterization enables optimized conventional material mixing of recovered fishing nets. In this way, economically attractive social return schemes can be introduced for used fishing nets, providing an economic incentive for fishers to return conventional fishing nets for recycling.

“…However, not all plastics are recycled due to a lack of economic viability and technical barrier solutions [108]. Several EU-funded projects have focused on upcycling marine litter and derelict fishing nets, such as BLUENET [109], OCEANETS [110], MARELITT [111], SEACYCLE [112]. For example, some companies have established yarn production by recycling fishing gears [113][114][115].…”

Microplastics: A Review of Policies and Responses

et al. 2022

Although (micro)plastic contamination is a worldwide concern, most scientific literature only restates that issue rather than presenting strategies to cope with it. This critical review assembles the current knowledge on policies and responses to tackle plastic pollution, including peer-reviewed scientific literature, gray literature and relevant reports to provide: (1) a timeline of policies directly or indirectly addressing microplastics; (2) the most up-to-date upstream responses to prevent microplastics pollution, such as circular economy, behavioral change, development of bio-based polymers and market-based instruments as well as source-specific strategies, focusing on the clothing industry, tire and road wear particles, antifouling paints and recreational activities; (3) a set of downstream responses tackling microplastics, such as waste to energy, degradation, water treatment plants and litter clean-up strategies; and examples of (4) multifaceted responses focused on both mitigating and preventing microplastics pollution, e.g., approaches implemented in fisheries and aquaculture facilities. Preventive strategies and multifaceted responses are postulated as pivotal to handling the exacerbated release of microplastics in the environment, while downstream responses stand out as auxiliary strategies to the chief upstream responses. The information gathered here bridges the knowledge gaps on (micro)plastic pollution by providing a synthesized baseline material for further studies addressing this environmental issue.
