Description

DESCRIPTION OF THE INDUSTRIAL INVENTION PATENT

The present invention relates to a method and related plant for the preparation of containers, intended for fish foods, and fishing tools in bioplastic obtained from fish waste material. The idea behind the present invention ? that of reusing the fish waste of molluscs (shells), cephalopods (gladius and bones) and fish (thorns) with a view to creating bioplastic compounds useful for the packaging of fish material. To date, the state-of-the-art bioplastics focus mainly on the use of corn starch. However, the corn? a precious food resource and ? therefore essential to find modalities? useful for reducing its use by achieving the goal of bio-material. Isn't the bio-material? toxic and does not come from the synthesis of chemicals, but from natural and renewable resources. Among the materials sustainable are wood, cork, cellulose, clay and concrete. In this regard, the use of waste fish material represents a valid possibility? for making containers (e.g. packaging) for fish and fishing gear (e.g. fake baits, floats, signal buoys, wires and nets for professional and sport fishing as an alternative to the current silicone and nylon ones), as an alternative to polystyrene and plastic.

The present method, the subject of the industrial invention patent, provides for the preparation of containers for fish and fishing gear in bioplastic obtained from fish waste material as follows: described below:

- a combined shredding phase of fish waste such as molluscs (shells), cephalopods (gladius and bones) and fish (thorns);

- a phase in which a quantity x of water, y of vinegar, a functional compound for fish bioplastic made from a quantity z of minced fish waste, an equal quantity z of corn starch and a quantity p of liquid glycerol. Are the quantities y,z,p a function of x in relation to the type of viscosity? to obtain and the conditions of temperature and humidity? on the side dish. Under standard conditions they are set equal to x/10.

- a phase in which the boiler is heated, bringing the material to the boil while constantly stirring the mixture;

- a phase of use of the compound with molds for the creation of containers/packaging or for the production of fishing gear or in the form of filaments/spools for 3D printers (PLA);

- a step for placing the products obtained in the previous step in a dryer.

The patent also provides for the plant for carrying out the aforementioned method characterized by:

- scrap collector module (1);

- module for environmental data acquisition (humidity, temperature) with CNC/PLC for plant control (2);

- HMI interface to define the semantics of the bio-plastic to be obtained and related quantitative parameters (3);

- shredder module with variable sieve (4);

- selector module for the quantity of waste to be used (5);

- water tank (6);

- vinegar tank (7);

- cornstarch tank (8);

- glycerol tank (9);

- dispenser module (10);

- boiler (11);

- mold press (12);

- filament extruder module (15);

- driving roller (13);

- dryer (14);

- seed dispenser (16).

The unit figure ? an exemplifying and non-limiting schematic representation of the system.

The method provides that seeds can be inserted into the bioplastic production process, to make it plantable. These seeds can be chosen according to appropriate semantics related to the product contained in the biomaterial containers. In fact, in a semantic key ? It is possible to ensure that by planting the containers they can give birth to mint or basil seedlings, pertinent to the type of fish product contained therein.
