Solid waste management system: an impressive case study

摘要

The paper discusses the incomplete and debatable integrated municipal solid waste management (MSW) system adopted in Campania Region, Southern Italy, with regard to characterization and disposal of Refuse Derived Fuel (RDF) and Stabilized Organic Fraction (SOF). The integrated management system planned in Campania was characterized by a source-separated collection of 35% of the total MSW production and the treatment of the restwaste in MBT (Mechanical Biological Treatment) plants in order to obtain RDF, metals and SOF. Currently seven RDF/Biostabilization plants have been working, while the three expected thermal treatment plants are under construction yet. The MBT plants have the same productive cycle. Owing to scant source-separated collection as well as MBT plants inefficiency, RDF quality was inadequate, according to Italian regulation limits. Moreover, the produced RDF bales are stored in several regional sites: this temporary solution is very dangerous due to the risk of contamination and accidental burning. SOF is disposed of in worked-out quarries equipped like sanitary landfills, due to its poor quality.
