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


In 2016, waste recovered from production activities was 77%. 23 percentage points more compared to 2015


93.2% of the waste produced belonged to the non-hazardous waste category and 6.8% 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 52,513 tonnes in 2016, up by 43.5% compared with the previous year. Out of the total waste produced, 93.2% belongs to the non-hazardous waste category and 6.8% to the hazardous waste category. The larger amount of waste products compared with the previous year is attributable to the exceptional work of replacing three pipelines (90 km of the Tarvisio Sergnano DN 850 pipeline, 1.4 km of the Bressanone Brunico DN 300 diversion, 2.3 km of the Adria DN 100 diversion), activities which involved the recovery of more than 29,500 tonnes of ferrous metal.

90.3% of waste was generated by production activities, of which 77% were recovered.
