## Abstract

The subject matter discloses a composite material comprising a first component and a second component, the first component comprising an organic element and a thermoplastic element and the second component comprising at least one element selected from the group consisting of vulcanized rubber and tire cords. The subject matter further discloses a process comprising mixing while heating under shear forces a first component comprising organic waste and thermoplastic waste with a second component comprising at least one element selected from the group consisting of vulcanized rubber and tire cords; to obtain a melt; processing the melt, the processing comprises at least cooling the melt to obtain a composite material comprising: organic element; thermoplastic element; and at least one element selected from the group consisting of vulcanized rubber and tire cords.
