Decomposition of solid waste in landfills causes global air pollution with methane, the most dangerous of the greenhouse gases. The emission potential of this gas is 28-36 times greater than that of CO2. With the help of methane-reducing Biocover, can find a solution to this problem. In this study, a biocover was developed in the laboratory to reduce methane emissions. When measuring the methane emissions of this biocover, data on the amount of carbon dioxide emissions were also obtained in parallel. The purpose o...

Landfills of municipal waste are important sources of methane emissions. The surface of the landfill area is the interface between the waste layer and the atmosphere. By creating a biocover cover layer, it is possible to reduce methane emissions that would refer to air quality. This innovative biocover technology aims to curtail methane emissions from various sources. The research delves into the effectiveness of this biocover in not only mitigating methane emissions but also its potential influence on nitrous oxi...

Global warming caused by greenhouse gas (GHG) emissions is a global problem. Solid municipal waste landfills are the third largest source of artificial methane emissions. Methane is one of the greenhouse gases contributing to global warming. The net zero emissions target was set to strike a balance between emissions and anthropogenic GHG disposal by 2050. Methane emissions from active or closed landfills may be reduced by methane oxidation, which is developed as a coating over these landfills. Methane (CH4) is an ...

The number of transport units in cities is increasing every year. This trend contributes to air pollution problems in many rapidly urbanizing countries. Various heavy metals and other chemical elements, including aluminum, have been related to air quality degradation. Poor air quality affects people, especially young children, the elderly, and people with chronic illnesses, causing health problems and aggravating existing problems. The aim of the research is to find out which parts of the city of Jelgava have the ...

Solid municipal waste landfills are the third largest source of man-made methane emissions. Methane is one of the greenhouse gases contributing to global warming. The capture of methane emissions in the waste sector is addressed by collecting it and using it for energy production. Methane emissions from active or closed landfills can be reduced by methane oxidation, which is developed as a covering over these landfills. It is usually composed of a gas distribution layer that favours micro-organisms that consume me...

The growing global population is creating high demand for transport and the various goods industries, which produce lead-generating emissions from air pollutants. The increase in lead concentration is very dangerous because it affects the nature and human health around us. The great concern for human health and the environment has contributed to research on lead concentrations around us. The aim of the study is to clarify the prevalence of lead in Jelgava between 2018 and 2021. The winter period was selected for t...
