Abstract
A method for obtaining mechanically recoverable recycled material from multilayer PET (polyethylene terephthalate) containers of post-consumer and/or post-industrial origin involves cleaning the containers, crushing them into pieces, mixing the pieces with a compatibilizing mixture and melting the mixed product to obtain a continuous filament. The compatibilising mixture is formed by at least: 10-45% thermoplastic polyolefin matrix; a reagent of plant origin in a percentage of less than 7.5% of the total mixture; and a rosin-based tackifier in a percentage of less than 7.5% of the total mixture.
