A2a in Milan in 2025: zero waste in landfill and one million tonnes of CO2 avoided

No waste in landfill and around one million tonnes of CO2 avoided. These are the environmental results of A2a in the Metropolitan City of Milan in 2025, contained in the tenth Territorial Sustainability Report presented today.

100% of the 772 thousand tons of waste collected in the municipalities served were sent for recovery, 64% material and 36% energy. The capital confirms itself among the most virtuous metropolises in Europe, with 63% of separate waste collection. Meanwhile, the first year of Amsa's new service contract has ended, whose customer satisfaction index, detected by the municipal administration, is equal to 7.5 out of 10, growing from 2023.

Investments in the fleet continue. Over 90% of vehicles for separate glass collection adopt "glass noise" technology, which halves the acoustic impact of the operations. Around 100 intelligent compacting bins have also been installed in the most frequented areas, with a capacity up to five times higher than that of traditional bins.

A contribution to the reduction of emissions comes from district heating. The network managed by the group has heated more than 230 thousand equivalent apartments, avoiding 106 thousand tonnes of CO2. The recovery of waste heat from the Avalon 3 data center in the Bisceglie area is expected by the end of 2026.
