Abstract: In the light of the
recent European environmental regulation, in Italy, waste collection management
has been involved in some important changes both from environmental and
management point of view. From the one hand, firms want to maximize the
quantity of collected Municipal Solid Waste (MSW) showing an increasing
capacity of waste collection per unit of labor and capital, from the other hand
they want to minimize the level of Undifferentiated Solid Wastes (USW) in order
to meet environmental goals. This paper extends the concept of Directional
Distance Function (DDF) to the waste sector, in which previous applications of
efficiency models have been mainly focused on the cost-function side. The idea
of DDF (by Chambers et al.,1996; 1998) is here applied to treat asymmetrically
two categories of outputs: one desirable (amount of MSW) and one undesirable
(level of undifferentiated wastes) both observed (with inputs) from a sample of
around 450 Italian municipalities during 2006. Computed efficiency scores are
analyzed in light of different tariff systems (e.g. flat fee and pay as you through),
different socio-economic contexts (e.g. Northern vs Southern Italy) and
prevalent political side in local government (Left wings vs Right-wing
parties). Keywords: 4-6 nanocompounds, atmospheric pollutants,
social costs evaluation, social saving, titanium dioxide.
