In recent years there has been growth in fishing and aquaculture (or fishing farming), two activities in which large volumes of plastic nets and gear are used. After their use, the disposal is uncontrolled. Unfortunately, in Greece there is no legislative framework or a management plan for the specific waste type. The life cycle analysis is the key part for the development of any type of management plan. In some countries there are good practices for their disposal and if they can be reused. For this reason, this thesis, conducting online research with an emphasis on case studies, analyzes the life cycle of plastic fishing nets from their production to their end of life i.e. their disposal. The ways of rejecting them were also examined as its problems arise from it. Management practices used around the world and their recovery, recycling and reuse are analyzed. Finally, a plan is proposed for the management of plastic fishing nets in Greece after their disposal. Keywords:
