Using Drone-Based TDLAS Column-Sensor to Measure Active Working Face Emissions at Canadian Landfills

Methane emissions from landfills contribute 20% of global emissions, making it the third largest anthropogenic source after fossil fuels and agriculture. The active working face is the largest emitting source at landfills across North America, contributing over half of total site emissions. This project focuses on measuring and mapping emissions from the active working face to better understand the spatial distribution of methane emissions in this area. It also aims to provide information on emission mitigation solutions by examining the impact of gas collection and control systems (GCCS) in and around the active working face. Additionally, this research aims to understand the role of climate, weather, waste composition, and site working practices as determinants of landfill active working face emissions. The results of my research will help to support the development of more effective strategies to mitigate landfill emissions and address climate change. 

Biography

Meaghan Amaral received a Bachelor of Arts and Science in Climate and Environment from St. Francis Xavier University, Canada, in 2024. During her undergrad, she gained 8 months of work experience at a landfill where she primarily ensured environmental compliance requirements were met through sampling and reporting, as well as managing the compost program. Through this experience, she gained an interest in sustainable waste management. Meaghan is now a graduate student at St. Francis Xavier pursuing a Master’s in Earth and Environmental Science with an anticipated graduation date of May 2026. The focus of her research is on testing the capabilities of drone-based sensor technology for measuring landfill surface emissions and using drone-based sensor technology to measure methane emissions from active working face areas at landfills in Canada.
