The waste that Snam produces is derived from two main areas of activity: production and well drilling


In 2018, waste recovered from production activities was 60%


86% of the waste produced belonged to the non-hazardous waste category and 14% to the hazardous waste category

The waste Snam produces can be linked to two main areas of activity:

  • Production: the waste generated derives mainly from plant maintenance and management, and has always been a relatively insignificant environmental factor, both in terms of quantity and type of waste. The majority of waste produced consists of ferrous materials that are recovered in full.
  • Well drilling: waste deriving from well drilling consists mainly of slurry typically produced by this activity.

Reclamation waste can also be produced during the laying of pipelines through contaminated sites not owned by Snam in which it must operate.


In 2018, total waste production stood at 28,286 tonnes (-48% compared with 2017), of which over 86% belonged to the category of non-hazardous waste.
91% of waste products is connected to the maintenance and management of plants and 9% to shaft drilling activities. 60% of waste from plant maintenance and management was sent for recovery.

The lower amount of waste produced in 2018 is attributable to the lack of extraordinary works for the replacement of pipelines, activities which were carried out in the previous two-year period and which involved the production and recovery of many tonnes of ferrous metals.
