Notes:
The recycling potential of used plastic fishing gear by melt reprocessing is examined from a materials standpoint, as part of broader efforts to combat marine pollution caused by plastic debris. The present paper focuses on the identification of plastics and contaminants in a large variety of collected fibrous fishing gear, and the characterization of plastics in terms of possible degradation in the marine environment and their expected thermal stability during reprocessing. None of the major plastics involved (nylons and HDPE) was found to be significantly altered after exposure; accelerated thermal stability tests also indicate that these plastics could be reprocessed to acceptable products. Strong evidence suggests, however, that PP found in minor quantities would further degrade during extrusion. The presence of asphaltic and alkyd-type coatings on the nylon fibers was shown to complicate the characterization and melt flow behavior. Preliminary data on extrusion conditions and the effects of coatings and additives on the mechanical properties of injection molded compounds are presented. General technical and economic aspects of complete recycling facilities are also discussed.
