“…For instance, two conventional (grate) combustion WtE facilities located in different cities of China are compared, and they represent a major discrepancy in terms of the embarked capital as an example. The WtE plant in the city of Foshan, with a capacity of 462 000 tons/year, requires an investment cost of $120 per annual capacity ton, whereas the plant in Shanghai, with a capacity of 495 000 tons per year, requires $282 per annual capacity ton 17 . WtE facilities in developing countries are apt to have a lower investment cost although the same Western technology is utilized.…”

Summary Utilizing waste‐to‐energy (WtE) technologies is becoming crucial in today's world where energy sources are scarce. Despite the fact that WtE technologies (incineration, gasification, pyrolysis, anaerobic digestion, and landfill gas recovery) have been analyzed thoroughly in the literature regarding their efficiency rates in treating waste, the applicability of each method to different waste compositions and in various economic environments has not been considered before. In this study, this issue is investigated by modeling and solving a mixed integer programming model. The model is illustrated in three settings, namely Turkey, Brazil, and Germany, each of which is an example of a lower middle income, upper middle income, and a high income country, respectively. The findings of the optimization model suggest that plasma‐arc gasification and advanced incineration stand out as the most efficient technologies to create the WtE conversion, provided that there are sufficient funds to build and run these facilities. If there are economic restraints, anaerobic digestion could be a more cost‐effective way to create energy from waste. However, the solutions can be highly dependent on the parameters of the problem, as indicated in the results of the sensitivity analysis performed. In particular, if CO2 emissions are a big concern, the optimization model favors more of plasma‐arc and pyrolysis technologies. Novelty Statement Despite a wide range of previous studies involving technical analysis of WtE technologies, an economic perspective involving facility building decisions comparing different income level countries has not been performed before. This study examines all waste‐to‐energy methods in the literature not only regarding their efficiency rates in treating waste but also selecting the most appropriate methodology in different settings. In this manner, considering different income level countries brings a proper perspective and novelty to the study.

“…Solid waste is a challenge faced by both developed and developing countries (Mbuligwe, 2002). However, solid waste management continues to be a major challenge that is faced by all urban areas in the world and this is a more prevalent issue in developing countries with rapidly growing cities and town developments (Jing et al, 2009 andGuerrero et al, 2013). Increasing population levels, rapid urbanization, booming economy and rise in community living standards which have significantly increased the speed of municipal solid waste generation in developing countries (Minghua et al, 2009).…”

As in many developing countries, Solid Waste Management (SWM) is a key issue in Sri Lanka, and the quantity and the quality of the waste generated are directly influenced by the knowledge, attitudes and practices of people. Poor community participation is one of the main barriers for finding a sustainable solution for the said problem. The main objective of this study is to investigate the relationship of knowledge and attitudes with the waste management practices followed by managerial officers in Sri Lanka which is considered as a significant group of the society because of their education level and direct involvement of decision making at organizational and national level. Population was selected as students who studied Master of Business Administration (MBA) of University of Sri Jayewardenepura as they are supposed to be the future leaders of the country. Among them hundred students were randomly selected to the sample, representing managerial level officers in different sectors. Knowledge, attitudes and practices were taken as variables and they were measured using few dimensions. Data was mainly collected through self-administered questionnaire. The version 22.0 SPSS package was used for data analysis. According to the findings, majority of MBA students possessed moderate level of knowledge and more than 75% of respondents had moderate level attitudes on solid waste related aspects. However, 15.9% of MBA students had poor attitudes on solid waste and especially on value of waste.Regarding their practices, nearly 40% of respondents follow poor waste management practices and it reached more than 55% in waste segregation and recycling behaviors. Knowledge on solid waste didn’t show a significant relationship with their practices. However, a weak positive correlation was found between overall attitudes and waste management practices (r = 0.267) and a moderate positive correlation between attitudes on responsibility on public participation and practices (r = 0.539). Therefore, among MBA students, only the attitudes showed a significant positive impact towards SWM practices, not the knowledge. Hence, through building correct attitudes which need to be initiated from ground level can effectively contribute to implement sustainable waste management mechanism as attitudes of these future leaders are influential not in individual level but also in organizational and national level.KeywordsSolid waste; Waste management practices; Knowledge; Attitudes; Managerial level officers
