MSW Solid State Anaerobic Digestion and Bioreactor landfill combined waste to Energy system: the Umbria Region case study

The management of waste represent a critical activity that have to be conduct in an efficient way due to the relevant impact that it can have on different environmental, economical and social aspects. For these reasons it is of prominence importance to pursue efficient strategies and technologies, on the basis of the features of the considered areas, able to reduce the impact of the problem in the most economical sustainable way. Among these strategies and technologies, the differentiate collection together with the exploitation of biological treatments for the biodegradable fraction of the MSW, can lead to some interesting environmental as economical advantages due to the possibility of producing both renewable energy as reusable materials. In this paper, considering the waste management system of the Umbria, a central Italy region, the possible benefits arising from the combined exploitation of the Solid State Anaerobic Digestion, for treating the MSW Organic Fraction arising from the differentiate collection, and the Bioreactor Landfill, for managing the Non Differentiate Waste residual fraction, have been analysed both from the experimental than theoretical point of view.
