Different Scenarios Of Solid Waste Management

Abstract
The final destination of municipal solid wastes requires the realization and
localization on the territory of important industrial plants (separation plants, WtE
systems, final landfills, and also other innovative solutions, like digesters or
gasifiers), together with the important aspects of cost; careful consideration is
also required about the effects of externality, chiefly concerning carbon balance,
with reference to GHG production. Taking into account the necessity to define
the choice for the rational individuation of the most correct waste management
system, in the present work we evaluated a specific Italian case relative to the
waste management for a city located in Piedmont (North Italy): it is important to
consider that the amount of wastes that are produced in this city corresponds to
about 540.000 t/y. For the correct management of this load we considered
different scenarios, by introducing thermal structures (direct incineration and
gasification plants) and other complementary systems (mechanical separation
plants, anaerobic digesters). The alternative scenarios have been carefully
studied and compared from the environmental and economic point of view in
order to obtain suitable choice criteria. The results of the specific case analysis
clearly indicate the environmental and economic convenience of the solution
based on the direct incineration.
