Abstract: A process for the manufacture of biodegradable plastic films in aqueous environment, starting from vegetal wastes in powder form is provided, without use in any steps of the process of chemical reagents and organic solvents that may leave harmful residues in the film, and without making use of operative conditions potentially compromising the environmental sustainability and an effortless scalability of the process.

Abstract: Process for treating a fibrous material, to make said material hydrophobic and/or water-repellent, comprising the operation of impregnating said material with a suspension comprising nanoparticles of a hydrophobic material and a cyanoacrylate in an organic solvent and causing the crosslinking of said cyanoacrylate; the process uses an amount of cyanoacrylate and a weight ratio with the nanoparticles such as to produce complete or partial coating of the fibrous material with a matrix of crosslinked cyanoacrylate in which said nanoparticles are dispersed.
