Kaatopaikkapäästöjen

Kaatopaikkapäästöt refer to the emissions released from landfills. These emissions primarily consist of landfill gas, which is a byproduct of the anaerobic decomposition of organic waste. The main components of landfill gas are methane (CH4) and carbon dioxide (CO2), both potent greenhouse gases. Additionally, trace amounts of other volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) can be present.

The decomposition process is influenced by factors such as the type of waste deposited, moisture content, temperature, and pH levels within the landfill. As organic materials like food scraps, yard waste, and paper break down in the absence of oxygen, they produce methane. This methane is a significant contributor to climate change. Carbon dioxide is also produced, though often in larger quantities than methane initially.

Managing kaatopaikkapäästöt is crucial for environmental protection. Landfills are often equipped with gas collection systems to capture the emitted gases. This captured gas can then be flared, converting methane into less potent carbon dioxide and water, or it can be used as an energy source through landfill gas-to-energy projects, generating electricity or heat. Proper landfill design, including lining and capping, also helps to control and minimize these emissions. Regulatory measures are in place in many countries to limit the release of these harmful gases into the atmosphere.
