Using biogas produced from agricultural waste offers several significant benefits, one of which is emission reduction. Biogas, primarily composed of methane and carbon dioxide, is generated through the anaerobic digestion of organic materials, including agricultural residues.

When biogas is utilized as a renewable energy source, it replaces fossil fuels in energy production, leading to a decrease in greenhouse gas emissions. This shift is crucial in addressing climate change, as the combustion of fossil fuels typically releases a significant amount of carbon dioxide into the atmosphere. By harnessing biogas, farmers can reduce their carbon footprint, mitigate methane emissions from decomposing waste, and contribute to a circular economy where waste products are transformed into valuable energy.

Moreover, using biogas as a clean energy source can lead to reductions in air pollutants, promoting better air quality. In rural and agricultural areas, this shift not only supports sustainable practices but also enhances energy security by providing a local source of energy, thereby reducing dependence on imported fossil fuels.

The other options, while important considerations in the context of agricultural waste management, do not directly pertain to the core benefits of biogas itself. Improved soil quality and increased crop yield are more related to the application of digestate (the byproduct of anaerobic digestion) as
