Milan sorted 42.1 per cent of all household rubbish for differential collection in June.
This brings the proportion over the first half-year of 2013 to a record of 41.4 per cent, or some 20 per cent more than in the same period of 2012.
Announcing the encouraging news, environment councillor Pierfrancesco Maran said: "Apart from being a legal obligation, sorting rubbish is good for the environment and is the best guarantee for not finding trash in the streets. And we were really pleased to welcome a delegation from Paris who came to study our system for collecting umido organic kitchen waste.”
Organic waste scored the highest increase, with a 63.5 per cent rise. With the extension of collection to the city's south-east quadrant in June, half of Milan is now covered for direct collection from households.
Other categories, too, have registered an increase, including plastic and metals, paper and cardboard, and used clothing. In the first five months of this year, AMSA collected over six tons of burnt-out light-bulbs and neon tubes - over 40 per cent more than in 2012.
