“…The power generation is the aim of some of the above-mentioned processes, and in others, the waste disposal is a priority. Nowadays, a proper management approach based on the sustainable development principles is that waste must be restored or reused as a potential source ( T. U. N. E. P. (UNEP), 2004 ; Dijkema et al., 2000 ; Seadon, 2010 ; Brunner and Rechberger, 2015 ; Leckner, 2015 ; Rogoff, 2013 ; Korhonen et al., 2003 ). To choose a proper waste management system, these ways were compared by different approaches such as life cycle assessment (LCA) ( Zhouet al., 2018 ; Liamsanguan and Gheewala, 2008a ) and economic analysis ( Santos et al., 2019 ).…”

This paper performs an emergy analysis (EmA) to compare two real power plants include a conventional natural gas steam power plant (NGPP) with one that burns municipal solid waste (MSWPP). For this purpose, the EmA is used to investigate the sustainability, renewability, environmental impacts, and economic issues. The capacity of the NGPP and MSWPP are 247.5 and 3 MW, respectively. Results from this study show that the percent of renewability (PR) and emergy sustainability index (ESI) of the MSWPP are much more than those of the NGPP. The PR and ESI of the MSWPP are 46.81 and 1.65, while for the NGPP are 5.01 and 0.05, respectively. It is proved that the MSWPP is more efficient and has the better environmental impacts compared to the NGPP. Moreover, a hypothetical MSWPP with the same electricity output of the NGPP is studied using the EmA. A more efficient system with the higher PR and ESI is observed compared to the other case studies. Beside of these advantages, use of the MSW has other benefits such as reducing the greenhouse gases released in the atmosphere, saving fossil fuels, low land area required compared to the landfill, speed and ease of disposal, and production of clean and useful ash.

“…Meanwhile, recent studies [8][9][10][11] have shown that solid waste management has evolved from the conventional practice of collection and disposal of waste and now incorporates series of cost-saving and natural resource-conserving options such as source reduction, reuse, recycling and waste-to-energy which generally divert waste from landfill sites. Particularly, composting of organic solid waste, which makes up a significant proportion of waste in the developing world has the potential to reduce emissions of toxic gases generated at landfill sites [12].…”

Abstract:Waste diversion from landfills has generally been neglected in the developing world despite its potential to prolong the lifespan of landfills and generate revenues. This study aims at characterizing diverted solid waste fractions at communal collection points in seven communities and determining the trends in landfilled solid waste due to the Pay-As-You-Throw (PAYT) mechanism. It is based on quantitative measurements of diverted waste by informal waste pickers at communal collection points in seven communities in the Kumasi metropolis and analysis of landfilled waste records prior to and after the introduction of the PAYT mechanism. The study shows a daily diversion rate of 19.4±9.2kg per informal waste picker per day with no statistically significant difference (p = 0.29). This constitutes just 0.5w/w% of the total waste stream at communal collection points. The diverted waste is dominated by plastics (50%) and metals (29%). Generally, the diverted waste quantities are hugely dependent on the storage capacities of the informal waste pickers while the types of recovered items depend on readily available market. The introduction of the PAYT system, as observed from the study, immediately caused a decline (28%) in waste disposed of at communal collection points but steadily appreciated with time (26% and 13% consecutive reductions in subsequent years). The study recommends support for the informal sector, Public-Private Partnerships for waste recycling and intensive public education on PAYT mechanism prior to and after its introduction.
