The trend can be traced to the E&P sector (over 77% of For non-hazardous waste, increases have been recorded
waste from Eni production activities) which, compared in the R&M and Chemicals sector (+35.5% equal to
to 2015, recorded a decrease of over 443,000 tonnes due approximately +18,700 tonnes for extraordinary activities
to the fall in hazardous waste (-27%, mainly owing to the in the systems of the Sannazzaro refinery, the annexing
reduction of oily sludge in Nigeria and the reduction of of the former EniPower plant to the Livorno refinery

For the other sectors, with regard to hazardous waste, (-18.2%, equal to approximately -2,290 tonnes), which
there has been a significant increase in G&P (+88%, can be traced to the maintenance activities in the

maintenance activities at the EniPower plants) and a production of sludge from water clarification thanks to the
reduction in R&M and Chemicals (-5.7%, equal to around improved quality of the procurement source (water from
-5,500 tonnes), mainly due to the contributions of the the Po river).
