The overall bloc diagram of such integrated system for management of unsorted MSW is shown in Figure 3. As told all MSW is biostabilised before selection screening to get a more efficient separation and reduction of possible malodours. to RDF production to material recovery for energy recovery Fig. 3. Bloc diagram of integrated system for management of MSW For the practical application of above schemes the regional territory has been divided in 15 Optimal Territorial Basins OTB 4 in Province of Foggia FG 1 FG 2 FG 4 and FG 5 4 62 Integrated Waste Management - Volume I in Province of Bari BA 1 BA 2 BA 4 and BA 5 2 in Province of Brindisi BR 1 and BR 2 2 in Province of Taranto TA 1 and TA 3 and 3 in Province of Lecce LE 1 LE 2 and LE 3 . Each OTB is served by treatment plants for a. qualification of recyclable fractions deriving from source separation or separate collection of MSW b. pre-treatment of residual waste deriving from conventional not-separate collection c. biostabilisation of above pretreated waste followed by mechanical separation into a wet fraction and a dry fraction being the former RBD landfilled or submitted to further curing for the production of RBM to be possibly reused for environmental purposes the latter FSC processed for conversion into RDF d. landfilling of process rejects or untreated waste during shutdown periods for maintenance or emergency.
