“…As the illustrated links indicate, these issues are considered primarily in the context of wastewater management. This issue has been studied, for example, in work by Maalouf and El-Fadel [ 46 ]. This study explores the economic dimension of introducing a food waste disposer (FWD) policy in the context of its implications for solid waste and wastewater management.…”

Food loss and waste represent a global problem in the ethical, social, environmental, and economic contexts. The aim of this article is to identify leading concepts in studies on food loss and waste in management research by network analysis of the co-occurrence of keywords, via mapping of knowledge domains, a method used in bibliometrics. We analyzed 2202 records from the Scopus database on food waste management with the aid of the VOSviewer software tool. In particular, keyword co-occurrence analysis was adopted to visually explore knowledge bases, topic distribution, and research fronts in the field of food waste management research. Ten representative areas were found concentrated in main keywords, namely, food waste, waste management, food, anaerobic digestion, waste disposal, recycling, waste treatment, municipal solid waste, solid waste, and refuse disposal.

“…In order to make decisions on technological selections to treat MSW, several factors must be considered including technical, economic, environmental, sociocultural, political, institutional, organizations and legal aspects of the local environment [101]. However analysis of all factors is often complex in developing countries due to the lack of data, and a few factors like the economic cost (EcC) and environmental cost (EnC) are often used as the basis of these analyses [13,102,103]. Table 6 depicts the average EcC and EnC costs (in USD) for treating 1 ton of MSW in developing countries for five treatment options as computed by various authors.…”

Recently, there are increased efforts by municipals and researchers to investigate the potential of utilizing municipal solid wastes (MSW) for resources recovery. In many parts of developing countries, MSW is mostly collected for disposal with little emphasis on resources recovery. However, the MSW has high organic and moisture contents, and are suitable substrates for anaerobic digestion (AD) process to recover biogas for energy and digestate which can be used as fertilizers or for soil amendments. Resources recovery from the AD process consists of four metabolic stages; hydrolysis, acidogenesis, acetogenesis, and methanogenesis. These metabolic stages can be affected by several factors such as the nature of substrates, accumulation of volatile fatty acids, and ammonia inhibition. In this review, different optimization strategies towards resources recoveries such as pre-treatment, codigestion, trace elements supplementation, optimization of key parameters and the use of granular activated carbon are discussed. The review reveals that the currently employed optimization strategies fall short in several ways and proposes the need for improvements.

“…It is inferred that these differences are related to the environmental and economic policies that prevail in the different countries and to the type of locality. Likewise, it should be mentioned that in rural areas the design and operation of landfills is not carried out in its entirety as indicated by Note: The table is made from interviews to the authorities responsible of waste management and adapted from 'Effect of a food waste disposer policy on solid waste and wastewater management with economic implications of environmental externalities' (Maalaouf and El-Fadel, 2017;Mao et al, 2015;World Bank, 2012).…”

The appropriate selection of treatment or final disposal for municipal solid waste generated by a population depends on multiple characteristics; decision-making becomes a challenge for those responsible for its integral management. Therefore, the objective of this research was to evaluate multi-scenarios of valorisation of the organic fraction of municipal solid waste. The methodology used included a sample of 421 houses to determine the generation and composition of the aforementioned municipal solid waste; this data served as input to be able to design four treatment and final disposal scenarios: current situation, composting, anaerobic digestion and landfill. The parameters of humidity, biochemical methane potential and biogas were used. In addition, organic fraction variability and treatment cost were considered. Data analysis included design of experiments with the uncertainty coefficient and predictive equations. The results showed that composting was the scenario that presented the highest coefficient of determination and therefore it would be the best choice to fit the particular conditions of the localities. It is concluded that this applied methodology can be used as a tool in the decision-making process regarding the valorisation of the organic fraction of municipal solid waste and can be replicated at a national and international level.
