Methane emissions from landfills are a significant contributor to greenhouse gas emissions and climate change. This article, hence, presents strategies for landfill gas collection systems aimed at improving methane recovery. A comparative analysis of gas collection system designs, including horizontal, vertical, and slotted wells, is presented. Additionally, the utilization of vacuum-assisted gas collection systems and gas permeable barriers is discussed, highlighting the potential benefits and drawbacks of each approach. Challenges and opportunities in implementing innovative landfill gas collection systems are discussed, including technical, regulatory, and financial aspects. Collaboration between stakeholders is emphasized as crucial for the successful implementation and operation of these systems. The potential of innovative landfill gas collection systems for reducing greenhouse gas emissions from landfills is highlighted, and a call to action for further research and implementation of these approaches is made. This article provides valuable information for researchers, practitioners, and policymakers interested in sustainable waste management and climate change mitigation.
