“…Biogas utilization for the energy recovery option was studied at Harmandali Landfill (Izmir/Turkey), and it was suggested that a power plant could generate electricity for approximately 2657 homes based on the size of project to be installed and per capita electricity consumption of 2847 kWh (Cakir et al, 2016;World Bank, 2017). Recently, a study investigated the economic and environmental benefits of LFG utilization in Oman, which has 300 dumpsites and seven engineered landfills (Abushammala et al, 2016). This study found that methane emission capture could attract profits up to US$333 million from the carbon reduction and US$291 million from the electricity generation simultaneously between 2016 and 2030.…”

“…Higher energy demand and environmental degradation due to the use of fossil fuels were motives to explore new sources of renewable energy and consequently to minimize adverse impacts on environmental resources, human health and sustainability. Previous studies have investigated the recovery of energy from landfill sites to generate electricity (Abushammala et al, 2016;Cakir et al, 2016;Rodrigue et al, 2018).…”

Sustainable solid waste management can provide pathways for renewable energy generation. The Kingdom of Bahrain has witnessed burgeoning municipal solid waste (MSW) generation rate due to socio-economic development. The authorities of this Small Island Developing State, which is located in arid environment, plan to produce 5% of the total electricity demand from renewable energy sources by 2025 and then double it to 10% by 2035. The US Environmental Protection Agency’s Landfill Gas Emission Model software was used to estimate the generation of biogas from MSW at the Askar Landfill site. Results envisaged that maximum landfill gas (LFG) emission rates will be in 2020 following landfill closure by the end of 2019, as an intentional scenario, with a maximum electricity generation potential of 57.4 GWh that could provide power to 488 households. Revenues from carbon credits and electricity sales were US$97.8 million and US$64.8 million, respectively, for the period 2020–2035. The internal combustion engine exhibited the most viable option based on economic analysis of the cost of alternative LFG energy recovery technologies. Our work highlights the potential to use LFG-to-energy technologies to reduce the carbon footprint in arid climates for developing countries with substantial electricity subsidization.

“…Currently, there are no treatment facilities in Oman, and consequently dumping waste into the landfill is the only ultimate way to dispose solid waste. Disposal of waste in landfills results in the generation of huge amounts of GHG, has a negative impact on human health and causes air and water pollution (Abushammala et al, 2016). Oman's current waste management system is struggling to handle the growing amounts of waste and this issue is difficult to resolve if Oman purely focuses on waste disposal (Ithraa, 2016).…”

Multi-criteria decision analysis of waste-to-energy technologies for municipal solid waste management in Sultanate of Oman

The Sultanate of Oman faces challenges, like rapid growth of waste generation, which calls for an optimum waste management strategy. Oman has witnessed the production of 1.5m t of municipal solid waste in 2012, which is expected to elevate to 1.89m t in 2030. This rapid increase needs to be tackled to reduce the generation rates along with the environmental impacts. Currently, there are no treatment facilities in Oman other than limited recycling, and therefore dumping waste into the landfill is the only ultimate way to dispose solid waste. Hence, this study is an initiative to improve the waste managing system in Oman by proposing optimum waste-to-energy technology using an analytical hierarchy process, manually and through expect choice software as well. In the present study, the identified important parameters were considered in an analytical hierarchy process model to rank the waste-to-energy technology alternatives. Based on the survey conducted, the most important criteria were environmental and economic, with the local priority vector of 0.400 and 0.277, respectively. This research concludes that the most suitable waste-to-energy technology for Oman, on the basis of the identified criteria, is anaerobic digestion followed by fermentation and incineration, which will help to reduce the amount of waste, greenhouse gas emissions and developing and maintaining costs of landfills.

An assessment of potential biomass resources in Nigeria for the production of methane and power generation is presented in this paper. Nigeria, as an underdeveloped and populous country, needs an uninterrupted source of energy. The country's energy problems have crippled large sectors of the economy. The percentage of people connected to the national grid is 40%. These 40% experience electricity supply failure on average 10–12 hours daily. Energy generation from municipal solid waste (MSW) is an effective MSW management strategy. Yearly waste generation has increased from 6,471 gigagrams (Gg) in 1959 to 26,600 Gg in 2015. This amount is projected to reach 36,250 Gg per year by 2030. Methane emission for 2015 was 491 Gg, and it is projected to reach 669 Gg in 2030. These values translate to 3.48 × 109 kilowatt hours (kWh) of electricity for 2015, with a projected 4.74 × 109 kWh by 2030. The revenue to be derived from the electricity that is generated could have been US$365.04 × 106 for 2015, and it is estimated that it will reach US$473.82 × 106 by 2030. It was found that methane emissions from MSW increased with time, and capturing this gas for energy production will lead to a sustainable waste management.
