Abstract
A process for enhancing biodegradability of polyolefinic materials is provided. The process includes providing a polyolefinic material, mixing the polyolefinic material with at least one fatty reagent, 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, letting the melted material cool at room temperature for a time sufficient to obtain a solidified product, and incubating the solidified product with at least one fungal mycelium selected from fungal strains secreting Unspecific Peroxygenases (UPO), in presence of a fungal culture medium.
Claims13
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.
