The Environmental Product Declaration (EPD), drawn up by Centraltubi S.p.A. for polyethylene pipes and for the distribution of combustible gases, highlights a significant commitment to sustainability. It is a type III environmental declaration according to UNI EN ISO 14020, which provides the environmental data of a product, applying the parameters introduced in the life cycle assessment (LCA) and reporting the flows of materials, energy and potential environmental impacts at various stages of its existence.

“Flexible” pipes (made of PE, PP, PVC and HDPE) are able to satisfy all the initial project needs in a more efficient manner due to the thermoplastic material characteristics. These characteristics can easily solve general work site problems because they are durable, chemically resistant and last but not least, easy to handle. The “rigid” ones instead (made of concrete, iron and stoneware) can offer a good static performance but they lose in durability, chemical resistance and being heavy demand more manipulation thus increasing installation costs.

Drainage networks for waste water or for drainage of inundated and non - meteoric rainwater pressure, can be realized using various types of piping. The experiences have highlighted over time the merits and defects of traditional pipes.

In October of 2022 CENTRALTUBI S.p.A. obtained the NF (French) mark on PE100 HT pipes complying with the NF114 regulation for "group 5" (TUBES EN POLYETHYLENE POUR CONFINEMENT DE TRANSPORT D'ELECTRICITE),
