Quantification and control of gaseous emissions from solid waste landfill surfaces

Area of Science:

• Environmental Science
• Waste Management
• Atmospheric Chemistry

Background:

• Landfilling is a primary global solid waste disposal method.
• Landfills release significant greenhouse gases (GHGs) and toxic odor compounds.
• Quantifying and controlling complex landfill gas emissions presents challenges.

Purpose of the Study:

• To comprehensively review landfill emission quantification and control strategies.
• To focus on greenhouse gases (methane, carbon dioxide, nitrous oxide) and odor compounds (sulfides).
• To integrate knowledge for improved monitoring and mitigation.

Main Methods:

• Review of existing literature on landfill emission monitoring and control.
• Emphasis on combining diverse monitoring approaches for data quality.
• Analysis of targeted and systematic approaches for emission reduction.

Main Results:

• Combining multiple emission monitoring techniques enhances data reliability.
• Effective landfill emission control requires compound-specific or integrated multi-method strategies.
• Diverse factors influence the emission and transformation of various landfill gases.

Conclusions:

• Integrated knowledge of quantification and control is crucial for managing GHGs and odor.
• This review provides a foundation for field monitoring and mitigation strategy development.
• Effective management of multiple landfill emissions requires a holistic approach.
