Abstract A process for separating heterogeneous plastic ma- terial into homogeneous fractions, which comprises: a) feeding the plastic material-in a triturated form to a first water-containing separation tank in order to separate the high specific weight products from the low specific weight products; b) recovering the mixture of high specific weight products from the bottom of said first separation tank and drying them in a first drier: c) treating the resulting mixture with a chemical agent cap- able of swelling/modifying the plastic materials which are sensible to said chemical agent; d) drying the products so treated and feeding them to a second separation tank, in which the non-swollen/non-modified plas- tic material precipitates while the remaining material, maintained on the surface, is discharged.
