Energy recovery from waste represents an important issue due to the possibility of combining economical, environmental, disposal and waste recovery needs. Anyway, the choice of the most suitable management system and/or technology, for achieving this goal, has to be carefully analysed in order to avoid operational, economical and also environmental problems. The direct combustion of waste, preferably of the dry waste fraction arising from differentiate collection or from the mechanically sieved one, by the exploitation of grid combustor with steam turbine energy conversion system, represents the state of the art in recovering both thermal and electrical energy from solid waste. Unfortunately this solution represents some technical and economical drawbacks related mainly to small size plants. In this case, different solutions, also involving the whole waste management system, can enable to adopt different systems capable of producing energy both from the differentiated than from the non-differentiated collected waste fraction. In particular, referring to the Umbria region waste management system, the adoption of wet landfill feasible scenario (i.e. bioreactor) is described, analysed and compared with the one exploiting a small size grid combustor based incineration plant with energy recovery.

Abstract
Energy recovery from waste represents an important issue due to the possibility of combining economical, environmental, disposal and waste recovery needs. Anyway, the choice of the most suitable management system and/or technology, for achieving this goal, has to be carefully analysed in order to avoid operational, economical and also environmental problems. The direct combustion of waste, preferably of the dry waste fraction arising from differentiate collection or from the mechanically sieved one, by the exploitation of grid combustor with steam turbine energy conversion system, represents the state of the art in recovering both thermal and electrical energy from solid waste. Unfortunately this solution represents some technical and economical drawbacks related mainly to small size plants. In this case, different solutions, also involving the whole waste management system, can enable to adopt different systems capable of producing energy both from the differentiated than from the non-differentiated collected waste fraction. In particular, referring to the Umbria region waste management system, the adoption of wet landfill feasible scenario (i.e. bioreactor) is described, analysed and compared with the one exploiting a small size grid combustor based incineration plant with energy recovery.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
