Municipal waste generation indicators at municipal level

The data in question concern the annual municipal waste production since 2006 quantified through the percentage of separate collection (rd_perc) and the total waste indicators (RT), undifferentiated municipal waste (RO) and separate collection (RD) expressed both in absolute terms (kgs) and in relation to resident inhabitants (kg/inhabitant). The data were provided by the waste management consortia and formally approved each year with specific provision. It should be noted that this data set provides indicators that have undergone some changes over the years due to a regulatory adjustment of the calculation method: until 2016, the calculation method set out in D.G.R. 43-435 of 10/07/2000 and s.m.i. was used, from 2017 onwards the method referred to in D.G.R. 15-5870 of 3/11/2017, consistent with the national calculation method provided for in Ministerial Decree 26/05/2016. In particular, until 2016 included (D.G.R. 43-435/2000) the waste of bulky and recovered raies (between 40 % and 60 % of what was collected) and the waste of multi-material separate collection (3 % for glass/metal and plastic/metal collection, 7 % for glass/plastic/metal collection and 20 % for other multi-material collections) were added in particular. In RD, therefore, the multi-material, the bulky waste and the raee initiated for recovery were counted net of the percentages of waste. From 2017 included in RD have included types of waste that were previously not counted, such as: household composting (provided that this activity is regulated by the municipality of reference, and with a maximum per capita limit of 120 kg), all waste assimilated to municipal waste (such as those produced by supermarkets, commercial activities and merchants), construction and demolition waste of domestic origin (with a limit of 15 kg per capita), road sweep waste started for recovery, and finally minor selective collections such as waste batteries, expired medicines, oils, varnishes and toners. In addition, all harvests are counted before waste. It should be noted that in Piedmont waste management consortia can have a territorial extension that goes beyond the provincial limits. This is the case of the municipalities of Moncalvo (AT) belonging to the Consorzio Casalese Riwauti di Alessandria, Mombaldone (AT) belonging to the Consortium of Waste Services of the Novese Tortonese Acquese and Ovadese of Alessandria, Moncucco Torinese (AT) member of the Chierese Consortium for the services of the Metropolitan City of Turin, Villata (VC) belonging to the Consortium of Basin Basin Novarese. For a correct analysis of the data at territorial level, two columns (“prov_common” and “prov_consortium”) were inserted in order to aggregate the data both by province of the municipality and by province of the consortium belonging to it.
