Biodegradable and compostable material for packaging obtained from the use of the whole wastes of production of food industries

The invention consists of a biodegradable and compostable packaging material obtained from the integral use of the waste from vegetable raw materials used in food industries. The manufacturing process includes a drying step, a grinding until the desired granulometry, an extrusion-cooking step of the dough obtained from the dried vegetables formulated with other ingredients. The uniqueness of the innovation is the total recovery of wastes. Unlike other existing processes, this invention does not involve the extraction processes of useful components (lignin, starch, etc.), but the employment of the entire waste, transformed into novel biodegradable materials.
State of development
Patent
Industrial application
The invention involves a wide range of actors along the food chain such as primary producers (farmers) who produce the waste, the food industries that transform the vegetables, even minimally processed such as the fresh-cut products and to the industries producing packaging materials. The process allows obtaining materials with valuable properties such as flexible, biodegradable, suitable to be shaped, with low water permeability. Also, the materials may be easiliy covered with a coating.
Advantage factor
The invention allows to avoid the expensive disposal of industrial plant waste, promoting their integral re-use for the manufacture of fully biodegradable materials, similar to the carton, but less permeable to water. The distinctive feature and its novelty is in the total recovery of wastes; unlike other existing processes, this invention does not involve the extraction processes of useful components (lignin, starch, etc.), but the use of the entire waste, transformed to biodegradable material
