Impiego, riutilizzo e riciclo di plastiche biodegradabili in impianti di mitilicoltura

The waste related to the fishing sector represents 14% of the so-called “marine litter” and causes a significant impact on marine biodiversity. The "socks" used for the cultivation of mussels represent 77% of the plastic waste deriving from the production chain and are in third place among the waste deposited on the seabed, especially in the vicinity of mussel farming plants. Equally irrefutable is the threat due to the degradation of livestock stockings which, breaking down into microplastics, directly threaten the entire food chain. To date, we want to put into practice a correct management of this type of waste through effective collection, which is followed by a treatment system oriented towards the recovery of the polymer used to make the socks. This research proposal is part of a context of innovation and research with the aim of proposing the creation of fully biodegradable and compostable socks for mussel farming in Mater-Bi®, a patented biopolymer produced by Novamont S.p.A. In addition to this study, the application of a reuse and recycling system for livestock stockings will be evaluated in harmony with the fundamental objectives of the green economy. The project will be carried out at the Lake of Faro (ME). This area was chosen by virtue of its historical vocation in the traditional production activities of mussel farming as well as for its renowned naturalistic value, falling within a SIC and ZSC site of the Oriented Natural Reserve of Capo Peloro, established by the Sicilian Region in 2001. Furthermore, in the recent 2020, the lake's waters obtained the sanitary status of “Zone A”, thus representing the best possible waters for shellfish farming activities. With this research project we want to give a strong push towards technological innovation and the use of biopolymers as an ecological alternative to the use of plastic polymers in mussel farming. The results of this experimentation will provide new inputs, contributing to environmental protection with particular reference to the well-being of the marine ecosystem and greater safety of the entire food chain.
