Waste

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

• Production: the waste generated derives mainly from plant maintenance and management (86% in 2020), 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 in the storage sector (7% in 2020).
• Reclamation waste: this type of waste can also be produced during the laying of pipelines through contaminated sites not owned by Snam in which it must operate (7% in 2020).

In 2020, total waste production amounted to 124,980 tonnes, showing a sharp increase compared to 2019 mainly due to the inclusion of Snam4Environment in the scope of consolidation, which was responsible for the production of 89,386 tonnes of waste (71.5% of the total). Renerwaste, a subsidiary of Snam4Environment, combines the need for urban waste disposal with the recovery of materials and energy, promoting the valorisation of depleted landfills and the conversion of composting plants from aerobic to anaerobic.

The 95% of the waste produced belongs to the non-hazardous waste category and 32% of the waste from production activities was sent for recovery.
