40 Extrusion International 4/2019 PIPE EXTRUSION The environmental impact of a piping system depends on its composition and application thereof. The factors determining the efficiency over the entire life cycle of a pipe are mainly: the type of raw material used, the production process, the product finish and its useful life PVC-O Pipes and Fittings – The Most Environmentally Friendly Solution for Water Transportation PVC-O pipes lifecycle PVC-O pipes are presented as the most ecological so- lution due to their better contribution to the correct sustainable development of the planet, as it has been demonstrated by different worldwide studies, among which we can highlight: “Estimación del consumo en- ergético y de la emisión de CO 2 asociado a la produc- ción, uso y disposición final de tuberías de PVC, PEHD, PP, Fundición y Hormigón” (University Politectnic of Catalunya) and the study “PVC-O Environmental Prod- uct Declaration” TEPPFA (The European Plastics Pipes and Fittings Association). Oriented PVC presents environmental advantages in all phases of its life cycle (Picture 2): Picture 1 Picture 2
