13 Claims

1. A process for enhancing biodegradability of polyolefinic materials, the process comprising the steps of:

(a) providing a polyolefinic material;

(b) mixing the polyolefinic material with at least one fatty reagent, with a ratio of fatty reagent/polyolefinic material ranging from 1/5 to 1/1 by weight;

(c) heating up the polyolefinic material mixed with the at least one fatty reagent to the melting temperature of the polyolefinic material to obtain a melted material;

(d) letting the melted material cool at room temperature for a time sufficient to obtain a solidified product; and

(e) incubating the solidified product with at least one fungal mycelium selected from fungal strains secreting Unspecific Peroxygenases (UPO), in presence of at least a fungal culture medium.
