Landfilling has been and still remains an important means of municipal solid waste management but it poses a threat to the purity of the environment, especially air. In the coming years, a radical decline in the share of landfilling in waste disposal practices should not be expected. However, this is not to say that people are powerless in the face of the emission of harmful gases into the atmosphere, the spread of bioaerosols and odors. There are many ways of preventing the negative impact of landfills or protecting the environment against such an impact. Some of these preventive and protective measures are described in Mitigation of Landfill Gas Emissions. Special attention is given to the application of anaerobic, aerobic and semi-aerobic bioreactor landfills for control of landfill gas emission. Different types of biotic systems for the oxidation of methane and trace gases, such as biocovers, biofilters, and biowindows, are also presented.

The Nordic Partnership Initiative on Upscaled Mitigation Action (NPI) supported developing countries in designing and implementing mitigation action and attracting funding from international climate finance and carbon markets. In Peru, the initiative focused on building readiness for mitigating greenhouse gas emissions in the municipal solid waste sector. It generated comprehensive information on the sector’s status and trends in terms of waste and emissions, mitigation potential and costs, and barriers to action. Mitigation plans for landfills were prepared, a robust information system developed, and policy reforms introduced for recognising waste as a valuable raw material. The NPI results have been integrated into national and local development plans and serve as valuable building blocks in the design and implementation of Peru’s mitigation pledges under the Paris Agreement.

ABSTRACT: Decay of waste within landfills is a contributing source to the greenhouse effect due to the production of methane. Larger landfills tend to have gas collection systems, which collect and convert gas into energy or flare it. Older and smaller landfills, however, usually vent this greenhouse gas into the atmosphere through passive vents. This study focuses on the attenuation of methane gas from these passive vents through the use of biofilters containing methanotrophic bacteria. These methanotrophic bacteria can oxidize methane into carbon dioxide, water, and biomass.

An Evaluation of Methane Mitigation Alternatives for Closed Municipal Landfills

Countries around the world face social, economic, and ecological damage from escalating natural disasters caused by climate change. In an effort to curtail climate change impacts, local and regional governments are beginning to employ green house gas (GHG) mitigation strategies to reduce their carbon footprint. These strategies work to eliminate a range of GHG emissions from entering the atmosphere. Apart from carbon dioxide (CO2), the most prevalent GHG is methane. In terms of global warming, methane is approximately 21 times more harmful to the atmosphere than CO2. Natural gas systems, coal mining, manure management, rice cultivation, wastewater treatment, and landfills all contribute to methane generation. According to the US Environmental Protection Agency's 2011 US GHG inventory, landfills generate 1.5% of total GHG emissions in carbon dioxide equivalents. Recognizing the global impacts of its policies and operations, municipalities are working to reduce their GHG emissions. Coalitions like the C40 Cities Climate Leadership Group were created to specifically address GHG reductions, which will result in a 248 million MT reduction in GHGs released to the atmosphere by 2020. Guided by existing literature, this Master's Report calculates methane generation and transport to determine the effectiveness of applying two methane mitigation alternatives--passive methane oxidation biocovers (PMOBs) and landfill gas to energy technologies (LFGTE)--at an inactive landfill site to reduce GHG emissions. LFGTE generates energy for direct use such as space heating or industrial processes or for electricity generation. Cost-saving strategies abound for landfills which utilize LFGTE. PMOBs optimize the landfill surface soil cover environment to promote microbial growth of bacteria, called methanotrophs, which convert methane into carbon dioxide. When employed, these mitigation alternatives are designed to significantly reduce methane emissions from landfills. The EPA has developed a computer modeling program (LANDGEM) to aid in the calculation of landfill gas generation. A hypothetical case study of a one million ton landfill was created and modeled for methane generation over a 35 year period. With methane generation rates calculated, assessment of potential LFGTE was performed and methane oxidation rate calculations were made to determine the impact of a PMOB and LFGTE on net GHG emissions at the landfill. The overall GHG reductions with these engineering controls were two-thirds of the level a landfill without controls would emit. These results indicate that implementing methane mitigation steps at closed landfills throughout the world would yield significant reductions in GHG emissions.
