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


In 2017, waste recovered from production activities was 80%. 3 percentage points more compared to 2016


93% of the waste produced belonged to the non-hazardous waste category and 7% 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.


Total waste production was approximately 54,413 tonnes in 2017, up by 3.6% compared with the previous year. Out of the total waste produced, 93% belongs to the non-hazardous waste category and 7% to the hazardous waste category. The larger amount of waste products compared with the previous year is attributable to the exceptional work of replacing one pipeline (Sergnano -Tarvisio DN 850 pipeline and its diversions), activities which involved the production and recovery of more than 24,980 tonnes of ferrous metal (about 46% of the total waste produced).

Waste recovered from production activities was 3 percentage points more, rising from 77% in 2016 to 80% in 2017.
