“…The financial model analyzed the current situation of MSW sector in Saudi Arabia showed that AD and gasification WTE plants are financially profitable endeavors in terms of investment indicators, i.e., net present value (NPV), internal rate of return (IRR), modified internal rate of return (MIRR), profitability index (PI), and Levelized Cost of Waste (LCOW) [63]. Recent studies reported new technologies such as membrane, solvent absorption, adsorption, and low-temperature techniques such as cryogenic could be successfully applied for capturing methane gas [64,65].…”

The continuous growth in population, urbanization, and industrial development has been increasing the generation of solid waste (SW) in the Kingdom of Saudi Arabia. Consequently, the associated greenhouse gas (GHG) emission is also following an increasing trend. The collection and use of greenhouse gases emitted from solid waste management practices are still limited. A causality analysis examined the driving factors of the emissions from solid waste management. The methane (CH4) emissions from municipal solid waste (MSW) increased with an increase in gross domestic product (GDP) per capita and urban population, and an increase in foreign direct investment (FDI) inflows and literacy rate was likely to reduce CH4 emissions from municipal solid waste and vice versa. The CH4 emission generated from industrial solid wastes was found to be positively related to GDP per capita, urban population, and FDI inflows. However, a decrease in the unemployment rate was likely to increase CH4 emissions from industrial solid wastes. The future greenhouse gas emissions were projected under different possible socio-economic conditions. The scenario analysis based on different variations of population and GDP growth revealed that methane emission from total waste would increase at an average annual rate of 5.13% between 2020 and 2050, and is projected to reach about 4000 Gg by the end of the year 2050. Although the Kingdom has been taking some initiatives towards climate change mitigation, it has significant opportunities to adopt some of the best practices in solid waste management including reduction, recycling, composting and waste-to-energy, and carbon capture and utilization. This study also put emphasis on developing appropriate policy approaches for climate change mitigation based on the circular economy which is gaining momentum in the Kingdom.

“…The MSW generation and treatment in landfills commonly including rapidly biodegradable waste that increased significantly GHG emissions releasing into the atmosphere [36], whilst LFG is mainly composed of CH4 and CO2 gases [37][38][39] contributing about 45-60% and 40-60% respectively [40]. Both CH4 and CO2 gases are the main GHGs because of their capacity to trap solar energy [41].…”

“…where 2 GHGi,CO eq Emission  is the emission of GHG i converted to the unit of CO2-eq; GHGi Emission is the emission of GHG i estimated in the unit of ton or kg, and index,i GWP is the Global Warming Potential of GHG i that can be referenced from Table 1 below. To calculate the total value of GHG emission reduction potential generated from landfills for each year based on the computing scenario plan having biogas recovery to produce power generation can be shown in (6) [36,44].…”

“…However, livestock population intensification is linked to an increase in waste production, reaching 26.5 million tons and 33.7 million m 3 for solid and liquid wastes, respectively (Nguyen Van Bo, 2017). Waste disposal is not yet organized, with an estimation of about 60% of wastes treated and used effectively through technologies as such biogas digesters and composting (Ginting et al, 2003;(Nguyen Van Bo, 2017;Yaman et al, 2020). The rest remains untreated and is directly released into the environment.…”

Increases in pig farm densities have caused great pressures on waste management systems and produce massive manure and urine quantities in Vietnam. This study aimed to identify the role and contributions of biogas digesters to better manage the sources of greenhouse gas (GHG) emissions from pig wastes for different types of pig farms in the north of Vietnam. Four provinces, namely Thanh Hoa, Phu Tho, Thai Binh, Vinh Phuc, were identified. A total of 24 farms were purposively selected including 16 small-size farms and 8 larger-size farms. The findings showed that GHG emissions from small-size farms (154.8 t CO2-eq.yr-1) did not significantly differ from the amounts measured in larger-size farms (139.1 t CO2-eq.yr-1) in the four surveyed provinces. The sampling position did not significantly affect the GHG emission rates, with 173.9 t CO2-eq.yr-1 inside piggeries and 120.8 t CO2-eq.yr-1 outside the outlet of the biogas digesters (p-value=0.09). N2O emissions require further measurements at different farm sizes and sites. These results confirmed that the pig waste management of biogas digesters for both small-size and larger-size pig farms is not completely efficient and that efforts need to be invested in to mitigate GHG emissions in pig production. Reducing pig density per piggery is highly recommended. The application of other alternative aerobic or anaerobic digestion technologies like vermicompost, effective microorganisms, and composting should also be encouraged and promoted.
