Abstract: A single-layer tubular structure intended to convey fluids for a motor vehicle, formed by a layer formed by a composition predominantly including at least one catalyzed semi-crystalline aliphatic polyamide, the composition being formed by at least 30% by weight, in particular at least 50% by weight, of recycled material originating from at least one single-layer and/or multi-layer tube that was intended to convey fluids for a motor vehicle, the at least one single-layer and/or multi-layer tube being formed by a composition that predominantly includes at least one catalyzed or non-catalyzed polyamide, said at least one single-layer and/or multi-layer tube having been crushed, then at least recompounding with or without the addition of at least one catalyst to be able to be recycled, a simple one-off crushing being excluded.
