Recovery and treatment

To improve the recovery process of waste collected (including through their transformation into energy) and promote separate waste collection to help reduce the environmental impact of cities.

KPI 2017 2018 2023 plan objective
Percentage of municipal waste collected sent for recovery of material or energy 99.0% 99.7% 99.0%
Percentage separate waste collection in the municipalities served (apart from Milan) 70.0% 74.3% 76.0%
Percentage separate waste collection in the city of Milan 54% 59.7% 65.0%
Waste treatment capacity (municipal + special waste) aimed at recovering material at the Group's plants (kt) 888 926 1,280
Waste treatment capacity aimed at energy recovery at the plants managed by the Group (kt) 2,355 2,471 2,886
CSS produced by Group plants (kt) 132 129 469

Sustainable development goal

RESPONSIBLE CONSUMPTION AND PRODUCTION

Ensure sustainable consumption and production patterns


 

INDUSTRIES, INNOVATION AND INFRASTRUCTURE

Build resilient infrastructure, promote sustainable industrialization and foster innovation

Material issues

2018 performance

3.787

milion tonnes of waste were processed by the plants

1.585

million tonnes of waste collected in the Municipalities served

352,000

tonnes of recovered secondary raw materials

 

754

 kWh of electricity energy was produced from every tonne of waste-toenergy waste

780

 kWh of thermal energy was produced from every tonne of waste-toenergy waste.

Final destination of municipal waste collected

Actions

  • –The Group's average differentiated collection increased by 4%. (In Brescia the Oratori campain, in Milan Ecoisola and sensibilisation of the bio plastic)
  • ––Start-up of the new plastic selection plant in Cavaglià (started in 2018)and in Muggiano (expected starting in spring 2019)
  • The construction of 4 new treatment plants for the wet waste fraction is planned (FORSU), for the following recovery of biomethane
  • Brescia awarded for the differentiated collection of steel packaging

2018 performance

9

GW of electric capacity installed

627

MWt of installed thermal energy capacity in the waste-to-energy plants

260

MWe of installed electricity capacity in the waste-to-energy plants

 

+94

MW of installed capacity purchase of new photovoltaic systems (+ 65 GWh of annual production)

30

km of water network replaced

Elecricity generated by type of source (2018)

* For non-hazardous waste, a renewable fraction of 51% was assumed (ref. Decree of the Ministry of Economic Development of December 18, 2008). As a result, the non-renewable fraction considered was 49%.

Material issues

  • – Numerous activities for the monitoring and safety of dams.
  • Completed the activities of flexibility of the CCGT of Sermide and Ponti sul Mincio and started the process for the CCGT of Cassano.
  • 77% of Milan's electricity distribution network joints replaced to improve resilience.
  • IA system for the efficiency of gas preheating activities has been implemented in order to reduce gas consumption. –The first 30 km of the sewerage system for connection to the new Valtrompia purifier have been built.
  • –A2A was awarded the tender for the gas distribution of te Municipality of Milan, investments in energy efficiency and modernization of networks.
  • Work on the new Nuvolera purification plant has been completed and will come into operation in 2019.
  • The design phase for the thermal storage tanks for district heating in Brescia has been completed.
