“…This assumption was made taking into consideration the EU request regarding the decrease of BMSW sent to the landfill. For light packaging, it was supposed that high efficiency SC, mainly for polyethylene terephthalate (PET) and high density polyethylene (HDPE), would be developed, as indicated also in the literature [41].…”

Abstract:In the new legislation framework enacted by new member countries of the European Union (EU), the characterization of municipal solid waste (MSW) represents an important instrument for local governments and sanitation operators in setting and achieving targets for waste recycling and recovery. This paper presents the results of a study conducted in accordance with the Romanian methodology for domestic wastes characterization ROMECOM, aiming to provide a proper basis for developing clear and realistic forecasts in current municipal waste management, based on MSW composition and generation rate. The analyzed MSW came both from areas where the waste is collected in mixed and separate ways, in urban and rural areas. The MSW composition by fraction is detailed for dense urban areas, urban areas, rural and touristic areas from Romania. Based on these results, the MSW composition was determined for the eight development regions in Romania, and a generation rate of 0.9·kgMSW inhabitant by selective collection (different efficiencies for urban and rural areas) with subsequent recovery of the separated materials and energy recovery of the residual waste in a large-scale waste to energy (WTE) plant.

“…Very high 3 THE ROLE OF BIO-DRYING AND SELECTIVE COLLECTION SCENARIOS The production of waste derived from human activity has increased because of population increases, and especially due to economic development which has transformed consumption patterns. The systems of waste collection are also changing, leading to an overall complex scenario where balanced interactions are compulsory [18]. In many cases, on the other hand, decision makers do not adopt a coordinated strategy.…”

“…In fact, the core of MBT is the biological process; thus, there must be putrescible materials in the stream. High efficiencies of SC (higher than 50%) can be obtained only by separating the sources of food waste [18]. As a consequence, the food waste remaining in the RMSW can decrease even below 10%, which, thus, strongly impacts on the management of MBTs [19].…”

Mechanical biological treatments (MBTs) are extensively used for managing municipal solid waste (MSW). There are four different methods: fertilizer or compost-like output production, biogas/energy production, wastederived fuel production and disposal in landfills. One issue is the varying characteristics of the waste fed over the lifetime of the plant. This problem is only partially related to the composition dynamics of the generated MSW. Indeed, the main source of input fluctuation of the plant is a result of the implementation of selective collection (SC) strategies, which modify the composition of residual MSW (RMSW). Often the SC strategies are not developed in harmony with the presence or planning of treatment plants, which can consequently suffer from significant variations. A lack of optimization in MSW management strategies and the implementation of new more stringent regulations applied to the final solid products from MBTs could result in a higher tariff for the users. This paper analyses these two problems in terms of two SC scenarios. The consequent effects on the composition of RMSW and on the performance of bio-drying (one of the MBTs options) are discussed. The effect of different SC strategies of MSW is analysed also in terms of RMSW suitability to be converted into refuse derived fuel/solid recovered fuel with simplified treatments. The role of respirometry is also discussed.

“…In the literature, an analysis of the effects of the operating hours scheduling is not common both for thermochemical processes [4,5] and for biochemical processes [6][7][8][9][10][11]. The aim of this paper is to go beyond the analyses based on overall balances [12,13].…”

The present paper gives a contribution to the understanding of the effects of variations in maintenance scheduling on the environmental impact of municipal solid waste incinerators. The proposed approach allows a vision of their impact beyond the conventional balances. The characteristics of a selected case study were put forward and discussed. A plant proposed for a region in the North East of Italy was chosen for the scheduling effects analysis because of the long period of non-operation of each waste treatment line: 3 months per year as requested from the local environmental protection agency. The following effects were discussed on a yearly basis: maintenance stop fractionation, maintenance stop lasting, maintenance stop seasonal scheduling; the last aspect was discussed also at device level. The extreme scenario of seasonal stop gave the opportunity of assessing the highest reduction of yearly average impact from the stack, varying the season of maintenance: a reduction up to 23% could be obtained for the pollutants concentration contribution at ground level in the area of highest impact, comparing the worst case with the best case by a diffusive model. In the case of more common periods of stops for maintenance the reduction would be lower. The role of district heating must be taken into account too.
