In 2016, total production of waste stood at approximately 52,513 tonnes (+43.5% compared with 2015) of which more than 93% belonged to the non-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 DN100 diversion), activities which involved the recovery of more than 29,500 tonnes of ferrous metal.
Waste production in Snam is mainly linked to plant maintenance and management (production activities) and from well drilling operations. Waste generated by reclamation works can also be produced during the laying of pipelines through contaminated sites, not owned by Snam, in which the Company needs to operate. In 2016, waste from production activities was 90.3% of total waste production. 77% of waste from production activities was recovered.
