“…The study shows that this scenario is the second best option in reducing CO 2 emissions and GWP (-1.138×10 4 kg CO 2 eq). Because of its higher environmental savings, the results of several LCA studies show that MRF is a better option for managing MSW because it saves more energy as compared to composting and the bio gasification process by minimizing the use of virgin resources [25]. Incineration is the process indicating less burden on environment compared to other scenarios (Table 4).…”

Municipal solid waste (MSW) includes packaging waste, yard waste, wood, textile, newsprints, bottles, food waste, metals, and plastics. Trade, industry, and human population growth plus variations in living standards and in consumption patterns have been the main factors for progressive increase in generating MSW. As a consequence, management of MSW is one of the major challenges for municipalities in the 21st century [1][2]. In developing Asian countries, these factors are Pol. J. Environ. Stud. Vol. 26, No. 3 (2017) AbstractThis paper evaluates the environmental impacts of various municipal solid waste (MSW) treatment options produced on-site simultaneously with energy and material recovery. The results present a comparison of life cycle assessment (LCA) for municipal solid waste management (MSWM) in five different waste scenarios along with baseline scenario of the Defence Housing Authority (DHA) in Lahore. All scenarios were modeled using EaseTech software. Nine impact categories were assessed and results were presented based on the ASTM D5231-92(2003) characterization method. Results revealed that a material recovery facility (MRF) had low global warming potential (GWP), but lower avoided burdens in other impact categories. The incineration process indicated fewer burdens on the environment such as GWP (-2.086×10 7 kg CO 2 eq) as compared to landfills (2.461×10 7 kg CO 2 eq). This was due to lower avoided emissions in the landfill process compared to incineration. The negative values in results represented higher avoided emissions in treatment processes. Bio-gasification avoided CO 2 emissions (-8.053×10 5 kg CO 2 eq), but showed negative impacts in other categories. Almost all impact categories were high in composting except for freshwater eutrophication. LCA results provided good knowledge for decision makers as a tool to decide what alternative is a better change for sustainable waste management.

“…In the two studies of Rigamonti et al [17,18] the rate of source separate collection involved is referred to the target for Italy in 2007 and the mid-term regional targets in Italy, respectively. The minimum level of recovery under national regulations-such as the Spanish National Waste Plan for the year 2015 [19] and the percentage of separated collection which is the minimum level required by the Italian legislation [20]-are also used. In one case study, the use of standards and guidelines is just mentioned without, however, going into further details [21].…”

“…The good practice criterion consists of taking an already existing and widespread waste management system as a reference, such as different collection models implemented in Spain at a national level [19], the level of source-separated collection that has been reached in the year of the study in some provinces in the North of Italy [18], and the options being considered by several Italian municipalities to recover energy from waste in the year of the study [13].…”

Life Cycle Assessment (LCA) is a decision support tool that can be used to assess the environmental performance of an integrated waste management system or to identify the system with the best performance through a comparative analysis of different scenarios. The results of the analysis depend primarily on how the scenarios to be compared are defined, that is on which waste fractions are assumed to be sent to certain treatments/destinations and in what amounts. This paper reviews LCAs of integrated waste management systems with the aim of exploring how the scenarios to be compared are defined in the preliminary phase of an LCA. This critical review highlighted that various criteria, more or less subjective, are generally used for the definition of scenarios. Furthermore, the number of scenarios identified and compared is generally limited; this may entail that only the best option among a limited set of possibilities can be selected, instead of identifying the best of all possible combinations. As a result, the advisability of identifying an integrated life cycle-based methodological approach that allows finding the most environmentally sound scenario among all of those that are theoretically possible is stressed.

Solid waste management was one of the most significant environmental issues encountered in developing countries. Quantity of produced waste as well as its composition was known to vary by general consumption patterns that were affected by socio‐economic status, household size, or even by seasons. Due to the dynamic nature of waste quantity and composition, the handling and disposal of waste in an economically and environmentally feasible way presented itself as a challenge. Therefore, in order to conduct a successful decision‐making process to determine the feasible and sustainable processes in the disposal of waste, priority should be given to the statement of the problem at hand. The aim of this study is to achieve a characterization of municipal solid waste of Istanbul, Turkey. Waste samples were collected from the transfer stations servicing certain zones of the city and consequently substance group, moisture content and calorific value analyses were performed over these samples. Results indicated that approximately 54% of the municipal solid waste composition was of organic nature. The paper/cardboard group was coming next in ranking with a proportion of 15.57%. Average moisture content of samples was calculated to be 62.41% and 1435 kcal kg−1 was calculated to represent the average calorific value. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 734–739, 2013
