Lightweight and durable fishing boats made of FRP are difficult to dismantle or dispose of once they have served their purpose, leading to problems such as them being left abandoned in harbors or illegally dumped. Documents from 1995 report that demonstration equipment was installed at the New Nagasaki Fishing Port and trial operations had begun. FRP is a material composed of resin and glass fiber. This facility tested a method of crushing and heating the hull to gasify the resin while retaining the glass fiber. According to a technical report by Mitsubishi Heavy Industries, the experiment was conducted primarily by Marino Forum 21 in collaboration with Nagasaki Prefecture and the company. In other words, while the New Nagasaki Fishing Port served as the experimental site, it cannot be confirmed that Nagasaki City was the entity responsible for implementing the project. Subsequently, the national government verified a system for collecting and crushing scrapped vessels to utilize the m as raw materials for cement or as fuel. In fiscal year 2008, full-scale operation of the FRP vessel recycling system began nationwide. The question of how to dispose of vessels left in ports has expanded into the development of collection systems that can be used in various regions.
