Using autonomous drones to map methane in landfills

Paving the way for the capture and use of methane, University of Michigan researchers can pin down concentrations of the gas in landfills using autonomous drones equipped with lasers. Traditionally, the EPA requires landfills to use surface measurements, where a person walks and takes methane concentration measurements at certain intervals across an entire landfill and this data is used for compliance only. The new method could offer greater precision and reduce the time and effort required, and generate data that can help us understand the ongoing biodegradation processes in the landfill.
