“…Ever increasing population growth in cities in pace with economic growth has led to an increased production of various types of municipal solid waste, in particular, medical waste [1]. Proper management of municipal waste in order to reduce its adverse effects on the environment and the health of citizens is a necessity [2][3][4]. Different types of municipal solid waste have numerous effects on health, environmental, economic and social aspects; Nowadays, the littered waste management is considered in priority [5].…”

Covid-19 Pandemic leads to medical services for the society all over the world. The Covid-19 pandemic influence the waste management and specially medical waste management. In this study, the effect of the Covid-19 outbreak on medical waste was evaluated via assessing the solid waste generation, composition, and management status in five hospitals in Iran. The results indicated that the epidemic Covid-19 leads to increased waste generation on average 102.2 % in both private and public hospitals. In addition, the ratio of infectious waste in the studied hospitals increased by an average of 9 % in medical waste composition and 121 % compared with before COVID-19 pandemic. Changes in plans and management measurement such as increasing the frequency of waste collection per week leads to lower the risk of infection transmission from medical waste in the studied hospitals. The results obtained from the present research clearly show the changes in medical waste generation and waste composition within pandemic Covid-19. In addition, established new ward, Covid-19 ward with high-infected waste led to new challenges which should be managed properly by change in routine activities.

“…To minimize the bad odor generated from a landfill site that affects near residents, it is important to consider wind direction. 62 Northwest is the prevailing wind direction in the study area; therefore, this direction is unsuitable to locate a sanitary landfill. SRTM DEM was used to obtain prevailing wind types in the study area.…”

Solid waste disposal is one of the challenging components in integrated solid waste management. Particularly the problem is prominent in cities with rapid population growth and waste generation. Harar, a capital city of Harari regional state located in the eastern part of Ethiopia, covers an area of 19.5 km2 and has a total population of 270 000. Despite the fastest population growth of the city, it doesn’t have a landfill site to accommodate the waste generated and open dumping is in full practice. As an integral part of a solid waste management plan, the construction of a landfill has been suggested by the city municipality. However, the multi-dimensional and conflicting aspect of landfill sitting, which involves environmental, social, technical, and economic considerations, challenges the location of a suitable landfill site. In the current study, we have applied geographic information system (GIS) and analytical hierarchy process (AHP) multi-criteria decision analysis to select a landfill site through minimizing conflicting interests. Environmental and socio-economic factors including well water, distance from residence, land use and land cover, elevation, slope, and wind direction were weighted to develop a suitability index for landfill siting. Experts’ opinion was obtained to rank the aforementioned factors. The required landfill size was determined based on population growth, waste generation rate, and waste volume/year. Accordingly, the suitability index resulted in 3% of the area as highly suitable, and the rest 0.29%, 14.18%, 52.75%, and 29.8% classified as unsuitable, least suitable, moderately suitable, and suitable, respectively. Considering the future trend of waste generation, 16 ha of land located in the eastern part of the city was selected as a candidate landfill site with all the required suitability. The results of this study can be used as an input for decision making in siting landfill for Harar city.

“…There are many studies on the site selection of SWSL by integrating multi-criteria decision-making methods with GIS The study of Küçükönder and Karabulut (2007) has been revealed that multi-criteria analysis method and GIS can produce an effective and applicable results by considering many physical, environmental, social and economic factors in the site. Similarly Karimi et al (2019), Pasalari et al (2019) and Ali et al (2021) indicate that an integrating approach of GIS and multi-criteria decision analysis is effective in landfill site selection. Khorsandi et al (2019) used AHP and order of preference technique according to similarity to ideal solution (TOPSIS) models to weight the layers and prioritize the determined areas, respectively.…”

Waste management has grown into a significant matter for cities in line with the population growth and increased urbanization. Waste must be properly disposed to avoid causing a problem for environmental and human health. A variety of methods are used to dispose waste. Sanitary landfill, which is among these methods, is one of the common methods used for its safety and affordability. In the implementation of this method, a suitable site selection is a major factor that affects the whole process ranging from the construction to the operation of a sanitary landfill. It is aimed to determine the most suitable solid waste sanitary landfills (SWSL) for the city of Denizli in consideration of site selection criteria regarding solid waste landfills. The relevant legislation, academic studies and the current situation of the study area were taken into consideration to determine site selection criteria for SWSL. In this context, residential areas, primary traffic roads, protected areas, slope, aspect, water surfaces, rock structure, fault line, hydrologic soil groups, land use capability classification and land cover were determined as a site selection criteria. In the study, Geographic Information Systems (GIS) was used in spatial analysis, and analytic hierarchy process (AHP), one of the multi-criteria decision making methods, was used in weighting the site selection criteria. According to the suitability map which is generated as a result of the study, 19.536,40 hectares (1.76%) of 1.109.742,16 hectares of the area was determined to be the "most suitable" for sanitary landfill while 260.520,26 hectares (23.48%) of it was determined to be "suitable". An ideal area was determined for the construction of a sanitary landfill on the areas determined as the "most suitable" in consideration of the requirements of the city of Denizli based on the projections for the year 2040.
