Estimation of Methane Emission and Electricity Generation Potential from Mavallipura Landfill Site, India

"Because methane is a major contributor to greenhouse gas emissions, it is important to determine methane emissions from municipal solid waste in order to minimize greenhouse gas emissions. " The aim of the investigation is to determine methane gas production from India's Mavallipura landfill site. According to Yedla's method, energy estimation of MSW is 2578 TJ, while landGEM's IPCC and LandGEM estimator estimate, the Mavallipura landfill was 2375 TJ and 1998 TJ. This research also estimates the maximum electricity generation from landfill gases at 30 percent. ".

Methane emission quantification from municipal waste landfills: models and computer software—a case study of Long An Province, Vietnam

"Vietnam is one of the nations particularly affected by climate change; therefore, finding and implementing solutions in order to adapt and respond effectively to climate change has played a huge role. " This paper focuses on forecasting and assessing CH_4, CO, H_2S, and CH_3SH emissions for a case study in Vietnam's Mekong Delta region, particularly in Thanh Hoa and Kien Tuong, according to four different scenarios, ensuring that the landfill gas emissions are controlled under an LFG flaring scheme from 2021 to 2030, according to four case studies. The total municipal solid waste volume in Long An province, from 2021 to 2030, is estimated at around 3. 5 million tonnes, with the potential waste generation index between 0. 7 and 1. 2 kg person-1 day-1. According to the established scenarios in the 2021–2030 period, there are approximately 32. 1 million m3 CH_4 and 1. 0 million u20135. 1 million CH_4 and 1. 0 million m3 CH_4 built at Thanh Hoa and Kien Tuong dumping sites, respectively. On the other hand, the scenario 4 model is found to be the most suitable option for GHG emissions monitoring and migration from this study area in the next two years. ".

Application of 3-nitrooxypropanol and canola oil to mitigate enteric methane emissions of beef cattle results in distinctly different effects on the rumen microbial community

"Background" The main greenhouse gas produced by ruminants is enteric methane, which was estimated at 2. 1 Gt of CO_2 equivalent in 2010, accounting for 4. 3 percent of global human anthropogenic greenhouse gas emissions. This study investigated the rumen microbial community in connection with enteric CH_4 emissions and ruminal fermentation in beef cattle. In contrast, OIL caused significant changes in the rumen microbial community by indefinitely altering the abundance of a variety of rumen microbes, lowering the number of fibrolytic bacteria and protozoa, resulting in altered rumen fermentation. Our results show that co-administering CH_4 inhibitors with distinct mechanisms of action can both increase CH_4 inhibition and reduce excessive accumulation of ruminal H_2. ".

Measurement of methane emissions from CNG fueling stations in East China

"However, currently, there is no measurement data on methane emissions from natural gas fueling stations in China. " According to the Environmental Protection Agency's Other Test Method 33A, a downwind quantification scheme was used to directly measure nine compressed natural gas fueling stations in East China. The emissions from gas fueling stations could be divided into intermittent emissions and continuous emissions, of which intermittent emissions were the primary source of methane. ".

Effects of green-synthesized CuO and ZnO nanoparticles on ruminal mitigation of methane emission to the enhancement of the cleaner environment

"This research was conducted to determine the effects of adding CuO and ZnO nanoparticles to alfalfa hay production in vitro gas and methane. " The CuO nanoparticle is not recommended biologically, but ZnO increased protozoa population and gas production; therefore, this nanoparticle has only positive effects on rumen fermentation and is recommended.

Optimization of Non-thermal Plasma-Assisted Catalytic Oxidation for Methane Emissions Abatement as an Exhaust Aftertreatment Technology

"This paper explores non-thermal plasma assisted catalytic methane oxidation as an alternative to low temperature methane slip abatement in biogas methane-powered vehicles' exhaust. " In addition, it was found that CH_4 conversion efficiency was dependent on feed gas compositions and gas hourly space velocity, as well as how the activation energy is introduced. For example, a combination of plasma and external heat sources has benefits in terms of CH_4 conversion as well as reduced plasma energy consumption. Following NTP-catalytic methane oxidation, the presence of N_2 and O_2 in the feed gas resulted in unfavourable NO_X formation that linearly increases with CH_4 conversion. These results reveal that the most effective aftertreatment option, according to these studies, involves the combination of an oxidation catalyst with plasma to target the hydrocarbon and CH_4 oxidation, as well as an ammonia-SCR system to convert the NO_X formed in a plasma assisted zone.
