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 2018 2019 2024 plan objective
Urban waste at landfill (% of total municipal waste collected) 0.3% 0.1% 0%
Percentage separate waste collection in the municipalities served (apart from Milan) (% of total municipal waste collected) 74.4% 74.1% 76%
Percentage separate waste collection in the city of Milan (% of total municipal waste collected) 59.7% 61.5% 65%
Waste treated (municipal + special) aimed at recovering material at the Group’s plants (thousands of tonnes) 926 980 1,500
Waste treated aimed at energy recovery at the plants managed by the Group (thousands of tonnes) 2,471 2,457 2,700
CSS produced by Group's plants (thousands of tonnes) 129 130 528
Biomethane produced by FORSU plants (Organic Fraction of Urban Solid Waste) (millions of m3)   New 20

Sustainable development goal


Ensure sustainable consumption and production patterns


Build resilient infrastructure, promote sustainable industrialization and foster innovation


Performance 2019


 tonnes of waste collected in the municipalities served



tonnes of secondary raw materials ready for new use



 kWh of electricity produced per tonne of waste treated



kWh of thermal energy produced per tonne of waste treated



of the total thermal energy produced by the Group comes from waste and biogas



the level of saparate collection of urban waste in all municipalities served

Final destination of municipal waste collected


  • Increased the Group’s average separate waste collection, thanks to increasingly widespread local initiatives
  • Bergamo awarded for the implementation of 2 waste reduction projects: the collection of used vegetable oils produced by households and the Ecovan, in which the citizens can dispose the hazardous household waste; Como awarded for the separate collection of the steel packaging
  • Entry to Ellen MacArthur Foundation's CE100 Program with the aim of accelerating the transition to a circular economy
  • A2A became the aim supporting member of the non-profit association “ReMade in Italy”, whose companies use recycled material and produce green products in all sectors
  • Within the project “Advanced forms of sewage sludge management in an innovative Lombard hub", A2A Ambiente will experiment the optimization of energy recovery of sewage sludge in co-combustion with other non-recyclable waste (Brescia) and in single combustion (Corteolona), also aimed at recovering phosphorous ashes, an essential nutrient, which can then be used in agriculture
  • A2A delivered nearly 50,000 aluminum water bottles to all first-grade secondary school children in the cities of Milan and Brescia. A similar initiative was also carried out with the University of Brescia and thanks to the contribution of A2A Ciclo Idrico, 8,500 water bottles were provided to freshmen

Waste processed by type of plant


  • Start-up the new plastic selection plant in Muggiano (Milan)
  • Acquisition of Electrometal, a company specialized in the recovery and treatment of industrial waste (two lines with an annual capacity of 107,000 tons)
  • Obtained the authorization to build the first plant at Lacchiarella to produce about 8 million cubic meters of biomethane
