The current opinion of regional government: .......shipping the waste abroad ....and of course going on with landfill disposal gm a ncini@d ii.unict.it CYPRUS 20 16 11

The national government VS the regional goverment: Sicily must increase recovery 5 or 6 “small” and have 2 WTE gasification plants close plants, one in to the existing landfills to Catania and one reduce transportation in Palermo costs and impact on the traffic gm a ncini@d ii.unict.it CYPRUS 20 16 12

METHODOLOGY Hypothesis for the integrated waste m anagem ent scenarios in Sicily Main cities Palermo - Catania - Messina Popoulation Waste 1,315,000 inhabitants 710,250 tons/ y Sm all towns Waste Popoulation 3,736,000 inhabitants 2,017,320 tons/ y gm a ncini@d ii.unict.it CYPRUS 20 16 16

METHODOLOGY Hypothesis for the integrated waste m anagem ent scenarios in Sicily Percentage of recovery for waste category in large cities and small towns. gm a ncini@d ii.unict.it CYPRUS 20 16 17

METHODOLOGY Hypothesis for the integrated waste m anagem ent scenarios in Sicily Five scenarios for waste management in the region were proposed in order to investigate the related environmental and economic transportation costs. A recovery rate equal to 50 % of the total waste produced (50 %MSW) in Sicily (about 1,300,000 tons/ y) was considered for all the scenarios, in an optimistic management prospective characterized by high rates of waste collection in the small towns. gm a ncini@d ii.unict.it CYPRUS 20 16 18

METHODOLOGY The procedure is based on a mathematical model running within a GIS software platform , able to include all relevant socio-economic and territorial data. TransCad was used to develop a model that: combines GIS and transportation m odeling capabilities in a single • integrated platform; can create and customize maps, build and maintain geographic data sets, and • perform many different types of spatial analysis. gm a ncini@d ii.unict.it CYPRUS 20 16 25

METHODOLOGY Definition of transportation cost C Tr = C f + C t + C pt + C tm C Tr = Cost of transportation C f = Fuel Cost C t = Tires Cost C pt = Property Tax C tm = Truck Maintenance Costs Using the above specific costs and assuming and average speeds of 30 km/ h in the urban road network and 55 km/ h in the extra-urban road network, a unit transportation cost of 0.11 €/ ton-km was estimated. gm a ncini@d ii.unict.it CYPRUS 20 16 29
