The landfill is a final disposal technique to confine municipal solid waste (MSW), where organic matter is degraded generating leachate and biogas composed of methane gases (CH4), carbon dioxide (CO2) and other gases that contribute to global warming. The objective of the current research was to estimate the amount of biogas generated through the LandGEM 3.03 mathematical model to determine the amount of electrical energy generated and the number of homes that would be supplied with electrical energy from 2021 to 2144. As a result of the application, it was estimated that in the Pichacay landfill, the highest point of biogas generation in 2053 would be 76,982,177 (m3/year) that would generate 81,226,339.36 (kWh/year), and would supply 5083 homes with electricity. Similarly, in the Las Iguanas landfill, the highest point would be 693,975,228 (m3/year) of biogas that produces 73,223,5296.7 (kWh/year) and would supply electricity to 45,825 homes. Of the performed gas analyses in the Pichacay landfill in 2020, an average of 51.49% CH4, 40.35% CO2, 1.75% O2 and 17.8% H2S was presented, while in the Las Iguanas landfill, for 2020 and 2021, we obtained an average of 51.88/CH4, 36.62% CO2, 1.01% O2 and 187.58 ppm H2S. Finally, the biogas generated by being harnessed minimizes the impacts related to global warming and climate change and would contribute electricity to the nearby communities.

Solid waste management is one of the biggest issues in India as well as in the world. The generation of solid waste should be estimated for proper management of municipal solid waste (MSW) of the cities.The segregation, collection, transportation and disposal of municipal solid waste (MSW) are currently done in very unscientific and causal way in India and in many other developing countries. This creates problem for environment in terms of water, air and odour pollution. In this study, municipal solid waste has been estimated for Patna city and management has been carried out from the point of view of the recovery resources. The components of MSW have been estimated and based on that, moisture, density and energy content have been quantified. Afterwards, chemical compositions have been calculated and chemical formula has been made for MSW. This composition can help to estimate requirement of oxygen to degrade MSW and recovery of methane and carbon dioxide from MSW. Generally, landfill for solid waste management is planned for fifteen years or more than that. It is carried out in several parts or layers which take many years. In this paper, the calculation of energy content, requirement of oxygen to degrade MSW and recovery of methane, carbon dioxide from MSW have been carried out for a year which can be done for whole landfill period.

The issue of greenhouse gas (GHG) emissions from municipal solid waste (MSW) is important in the context of climate change. Reduction of GHGs from waste disposal systems is one of the management strategies forming part of Thailand’s National Economic and Social Development Plan. This project evaluated emissions from a municipal solid waste system covering transportation and disposal in Lampang Municipality, northern Thailand. GHG emissions from transportation were estimated by the Institute for Global Environmental Strategies (IGES) based on the travel distance of the vehicles, using a vehicle emission model and vehicle fuel consumption. GHG emissions during the disposal process were also estimated based mainly on the model of IGES. The results indicated that GHG emissions from sanitary landfill were highly dominated by methane (CH4) emissions (20,346 tons CO2eq a-1). In addition, carbon dioxide (CO2) was emitted (226 tons a-1) from the transportation process. This evaluation found that GHG emission estimates based on travel distance were lower than those based on fuel consumption (44 %). Furthermore, changing from diesel fuel to compressed natural gas will reduce transportation emissions by approximately 7 %.

Abstract The quantities of waste generation are drastically increased every day, and most of the waste is disposed off through open dump and landfilling. Methane, carbon dioxide, and nitrous oxide are major greenhouse gases (GHG’s) produced from landfill sites. However, the global warming potential of methane is 21 times higher than that of carbon dioxide. Hence, there is immense concern for utilization from landfill sites. In developing countries, the composition of municipal solid waste (MSW) has higher biodegradable waste (50–60%). This leads to emit higher GHG’s from a per ton of MSW compared to the developed world. In this study, the attempt will be made to estimate the amount of carbon stored in MSW burial in landfills. Tests were conducted in two different locations at the Mavallipura landfill. MSW samples were collected for every meter interval (1-2m, 2-3m & so on) up to 6m. The result shows that carbon stored in organic matter increases with depth from approximately 2.2% at 1.0 m depth to 4.8% at 6m depth. Based on MSW's carbon storage factor and data on MSW generation, global carbon sequestration from MSW burial in the Mavallipura landfill is estimated to be at least 10 million metric tons per year. Also, the study aims to quantify methane gas production from the ward levels and the Mavallipura landfill site in India.
