Abstract

Separate collection of municipal solid waste (MSW) is mandatory in Italy, and an increasingly higher standard of efficiency is applied; in fact, the target value set by regulation is 65%.

In the last 20 years, separate collection efficiency increased from 9.4% with 80% national MSW landfilled, and only one region was over 25% separate collection to 58.1% with 22% national MSW landfilled and 12 of 20 regions over 55% separate collection. However, significant differences are present in the three Italian macro regions (North, Center and South).

This paper analyzes the composition of waste carried in most Italian regions to evaluate the effect of separate collection on the composition of mixed municipal solid waste (unsorted). Moreover, a regression analysis on the same data allows to assess this latter as a function of separate collection efficiency.

Keywords: Separate collection efficiency, Mixed municipal waste, Landfill.
