A method for making a biodegradable container, the biodegradable container comprising a structure with one or more layers of puffed and pressed cereal seeds, bound together by a quantity of starch of said cooked cereal seeds, said container obtained by a process having the following steps:
- macerating a predetermined quantity of raw cereals in water for about 12 hours, to eliminate part of the external starch;
- drying the cereals macerated in the previous step by placing them in a dry environment for a further 12-24 hours, to adjust the moisture level of the cereal around values determined according to the subsequent steps;
- placing the cereals thus prepared on a metal mould;
- cooking the cereals, binding the individual seeds together, at a temperature of about 200-270° C. and at a pressure between 15 and 55 kg/cm2, to create a compact structure by binding the cereal seeds through the starch present in said seeds;
- and
- ejecting the cereals from the mould, causing a sudden drop in pressure and temperature, to obtain an immediate expansion of steam and air inside the individual cereal seeds, transforming them into cereals puffed and pressed together to form a single block of material having the shape and dimensions of the mould.
