A method for making a recycled flexible hose for transporting fluids, the method comprising the steps of: - providing a ground mixture obtained by grinding a reinforced flexible hose which includes: - at least one first load-bearing layer made of a first polymeric material; - at least one second covering layer arranged externally to said at least one first load-bearing layer made of a second polymeric material; - at least one reinforcement layer interposed between said at least one first and one second layer (10, 20) made of a third polymeric material; wherein said first and second polymeric material are thermoplastic elastomers, said third polymeric material being a thermoplastic polymeric material; wherein said first, second and third polymeric material are mutually compatible, so that the flexible hose can be ground without separation between said at least one first and one second layer (10, 20) and said at least one reinforcement layer; - extruding a fourth polymeric material comprising said ground mixture to obtain at least one first layer of the recycled flexible hose; wherein said fourth polymeric material comprises said ground mixture and at least one fifth polymeric material compatible therewith, said fifth polymeric material being a virgin thermoplastic elastomer; wherein said fourth polymeric material has a weight ratio between said ground mixture and said at least one fifth polymeric material comprised between 1:99 and 30:70. - providing a ground mixture obtained by grinding a reinforced flexible hose which includes: - at least one first load-bearing layer made of a first polymeric material; - at least one second covering layer arranged externally to said at least one first load-bearing layer made of a second polymeric material; - at least one reinforcement layer interposed between said at least one first and one second layer (10, 20) made of a third polymeric material; wherein said first and second polymeric material are thermoplastic elastomers, said third polymeric material being a thermoplastic polymeric material; wherein said first, second and third polymeric material are mutually compatible, so that the flexible hose can be ground without separation between said at least one first and one second layer (10, 20) and said at least one reinforcement layer; - extruding a fourth polymeric material comprising said ground mixture to obtain at least one first layer of the recycled flexible hose; wherein said fourth polymeric material comprises said ground mixture and at least one fifth polymeric material compatible therewith, said fifth polymeric material being a virgin thermoplastic elastomer; wherein said fourth polymeric material has a weight ratio between said ground mixture and said at least one fifth polymeric material comprised between 1:99 and 30:70. - at least one first load-bearing layer made of a first polymeric material; - at least one second covering layer arranged externally to said at least one first load-bearing layer made of a second polymeric material; - at least one reinforcement layer interposed between said at least one first and one second layer (10, 20) made of a third polymeric material; wherein said first and second polymeric material are thermoplastic elastomers, said third polymeric material being a thermoplastic polymeric material; wherein said first, second and third polymeric material are mutually compatible, so that the flexible hose can be ground without separation between said at least one first and one second layer (10, 20) and said at least one reinforcement layer; wherein said first and second polymeric material are thermoplastic elastomers, said third polymeric material being a thermoplastic polymeric material; wherein said first, second and third polymeric material are mutually compatible, so that the flexible hose can be ground without separation between said at least one first and one second layer (10, 20) and said at least one reinforcement layer; - extruding a fourth polymeric material comprising said ground mixture to obtain at least one first layer of the recycled flexible hose; wherein said fourth polymeric material comprises said ground mixture and at least one fifth polymeric material compatible therewith, said fifth polymeric material being a virgin thermoplastic elastomer; wherein said fourth polymeric material has a weight ratio between said ground mixture and said at least one fifth polymeric material comprised between 1:99 and 30:70. wherein said fourth polymeric material comprises said ground mixture and at least one fifth polymeric material compatible therewith, said fifth polymeric material being a virgin thermoplastic elastomer; wherein said fourth polymeric material has a weight ratio between said ground mixture and said at least one fifth polymeric material comprised between 1:99 and 30:70.
