“…This result revealed the ability of waste recycling systems to dampen the uncertainty associated with energy consumption. In continuation, Russo and Verda [148] showed that the selective collection of paper could result in higher variations in the exergy efficiency values of the first system, followed by the selective collection of organic and plastic wastes. Unlike paper and plastic wastes, the higher selective collection of organic wastes could improve the exergy efficiency values of both systems.…”

“…The aim is to produce the Refused Derived Fuel (RDF) to be used in WtE plants or cement kilns. The operation of the plant has been deeply analysed in [19], which is the reference for the Recovery Factor Transfer Function (RFTF) matrix used for mass balance, the energy consumption and cost of each equipment and the calculation of the material streams exergy content. The paper recycling plant includes the stock preparation (i.e.…”

Development of an Integrated Solid Waste Management (ISWM) system is a continuous challenge for local communities. These systems should be properly designed, paying particular attention to the optimal connection of their subsystems. Among them, the Solid Waste (SW) collection system has a primary influence. The design variables (e.g. unit collection basin and weekly removal) can be optimized according to the variation of external parameters (e.g. penetration of selective collection, population density). The objective is the minimization of specific collection cost, maintaining the maximum collection efficiency. Once the collection system is optimized, its influence on the entire SW treatment chain is evaluated. To this end, a multi-objective optimization is implemented taking into account the global cost and exergy efficiency of waste treatment. The analysed system is composed by a paper recycling plant for cardboard production and a Mechanical Biological Treatment plant for the Residual Unsorted Waste treatment, with production of Refused Derived Fuel.

“…Thermo-chemical processes such as MSW incineration, gasification and pyrolysis allow for significant reductions in the mass of MSW that otherwise would be sent to MSW landfills: according to Arena et al [8], a waste mass reduction of up to 88% can be achieved, but the residual amount of waste could be further reduced if options for bottom ash recycling are taken into account. If properly combined with an efficient selective collection system and with mechanical-biological treatments (MBTs) within integrated waste management schemes, WtE plants could be adopted during the transition towards resource circularity to limit the use of landfills and reduce the related environmental problems in developed and developing countries [9][10][11][12][13][14].…”

Despite the efforts made towards circularity approaches in waste management, waste-to-energy (WtE) processes still represent a key step because they allow recovering energy from waste, reducing the amount of waste residuals that require landfill disposal and reusing part of the residuals for specific purposes (e.g. in the construction sector). However, the direct (incineration) or indirect (gasification) combustion of waste generates relatively high emissions of several air pollutants, with different levels of toxicity. In specific situations, the presence of a waste combustion plant may be incompatible with the presence of population nearby, especially in areas where the dispersion of air pollutants is limited by the local morphology and/or by unfavourable meteorological conditions. In such contexts, an alternative option exists: the conversion of the syngas produced by waste gasification into commercial products or fuels. This alternative would guarantee a significant reduction of the impacts on the local air quality, and it is expected to increase the level of acceptability of the WtE sector by the population: the syngas would not be burned locally to generate energy, but it would be used to produce valuable products or replace traditional fuels with more sustainable alternatives. Thus, this paper aims at discussing the potential local impacts of traditional WtE plants and the opportunities related to alternative WtE approaches that may increase the level of sustainability of this sector. This paper will make a specific reference to mountainous regions, where the atmospheric dispersion of air pollutants may be negatively affected by the local morphology. To better illustrate the potential issues involved, some case studies located in an Alpine valley of Italy will be presented and discussed.
