Waste

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

• Production: the waste generated derives mainly from plant maintenance and management (71% in 2019), 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 (29% in 2019).

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

In 2019, total waste production stood at approximately 27,823 tonnes (-2% compared to 2018) of which more than 80% belonged to the non-hazardous waste category. 42% of waste from production activities was sent for recovery.
