Circular economy

Valorization of waste as a resource, from collection to disposal, favouring, where possible, the recovery of materials, the minimization of waste sent to landfills, also thanks to waste-to-energy; development of separate waste collection, efficient management of landfills, sludge and waste water, also through the adoption of biogas production technologies

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

Reduction policies

To reduce the production of waste through a prevention, reduction and reuse policy

KPI 2018 2019 2024 Plan Objective ID Termine
Territories where waste prevention and reduction actions are active (% of total inhabitants served) 81% 82% >80%/year 875 934

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 ID Termine
Urban waste at landfill (% of total municipal waste collected) 0.3% 0.1% 0% 875 934
