“…Today, the most mature and robust technology for energy recovery is incineration, where in Europe more than 20% of the MSW stream is valorised [2,3]. The main advantages of Solid Recovered Fuel (SRF) incineration over using MSW as fuel can be summed up in higher process efficiency, better quality of flue gases and significant reduction of heavy metals in the fly ashes.…”

This research presents an in-depth environmental analysis of centralized versus distributed approaches on Municipal Solid Waste Management (MSWM) when selective collection (SC) reaches high rates. The goal of this study was to assess the major qualitative and quantitative emissions (CO, CO 2 , CH 4 , H 2 S, NO x , SO 2 and Volatile Organic Compounds) resulting from waste transport and treatment. The selection of the input data was made for a MSWM real case study for the Trentino region (Italy). Two main scenarios were developed and compared from an environmental point of view, for the organic fraction of waste (OFMSW) and residual waste (RMSW) treatment on site or at distance. The first scenario considers the OFMSW treatment in the studied region, using an anaerobic digestion process with biogas and compost production or its treatment at about 120 km from the place where the waste material was produced. In the second scenario, the RMSW is designated to an incineration plant that could be placed near the studied region or could be subject pre-treated for Solid Recovered Fuel (SRF) production that can be valorised in a plant located at about 170 km. In order to evaluate the waste transport emissions, the COPERT computer program was used, considering the type of vehicle, fuel, load and speed. For waste treatment the emissions by type of pollutant are also assessed. In the results, it was highlighted that the transport environmental impact is higher in the biological treatment case. The results obtained can be used for the future development of MSW management strategies offering better environmental performances.

“…At the moment the linear economy is being gradually replaced by the CE that aims towards a zero waste framework [12][13][14][15][16] The main factors that are underlying the bases of any sustainable waste management are the reliable and up-to-date information and their trends regarding the quantitative and qualitative characteristics of the MSW stream, considering the demographic changes, the socio-economic and technological maturity, environmental policies, decision-makers and the interests of the parties involved in the process [17][18][19]. The most advanced and sustainable, Integrated Municipal Solid Waste Management Systems must maintain an equilibrium between the separately collected (SC) waste fractions and the Residual Municipal Solid Waste (RMSW), both of them being suitable for material and energy recovery.…”

Energy recovery from Municipal Solid Waste in EU: proposals to assess the management performance under a circular economy perspective

Abstract. In 2015 the European Commission issued a package of documents on Circular Economy concerning an integrated revision of legislative proposals on waste management. The aim was to stimulate a European transition towards a circular economy concept, which is expected to foster competitiveness, sustainable economic growth and new jobs generation. Three indicators are proposed in this paper to contribute to the assessment of the energy recovery management performance from MSW in a scenario of circular economy: a) referring to MSW directly used (RMSW) or indirectly used (SRF) as input of thermochemical plants, an indicator can be the percentage of waste having LHV > 13MJ/kg; b) referring to the MSW directly or indirectly used as input of thermochemical plants, the percentage of waste having ash recovered; c) referring to food waste, percentage of this stream sent to anaerobic digestion. The above indicators, proposed and discussed in this paper, have to be integrated with other ones in order to complete the quantification of the role of MSW management in term of energy recovery under a circular economy strategy. It is not the aim of the present paper to give a comprehensive solution to this complex issue.

Abstract:A model of biogas generation was modified and applied to the case of a sanitary landfill in Italy. The modifications considered the role of the temperature field normally established within each layer of waste. It must be pointed out the temperature affects the anaerobic biodegradation kinetics. In order to assess the effect of moisture on the waste biodegradation rate, on the bacteria process and then on the methane production, the model was compared with the LandGEM one. Information on the initial water content came from data concerning waste composition. No additional information about the hydrological balance was available. Thus, nine sets of kinetic constants, derived by literature, were adopted for the simulations. Results showed a significant variability of the maximal hourly biogas flows on a yearly basis, with consequences for the collectable amount during the operating period of a hypothetical engine. The approach is a useful tool to assess the lowest and highest biogas productivity in order to analyze the viability of biogas exploitation for energy purposes. This is useful also in countries that must plan for biogas exploitation from old and new landfills, as a consequence of developments in the waste sector.
