A vulcanizable rubber composition comprises an interpenetrating or ionic network (IPN)-promoting resin. The resin comprises side chain functional groups along the resin backbone, which, in the presence of an additive material, form the connections that make up the IPN. In one embodiment, such material is ZnO. A method for forming the rubber composition comprises, in a productive step, mixing the product of the non-productive step, the zinc oxide, and a resin derived from maleic anhydride. The zinc oxide and the resin are simultaneously added to the composition during the productive mixing stage. The rubber composition can be cured and incorporated in a tire component, such as, a tread.

A composite material consisting of a bio-filler and a thermoplastic matrix is described. The bio-filler derives from the lees taken as solid/liquid residue from the bottom of containers containing wine or must, after fermentation, during storage or after any other treatment of wine or must, as well as after filtration, centrifugation or after any process of separation of wine or must. A process for obtaining such a bio-filler and three processes for obtaining an article with such a composite material is also described.
