PACK 1: GASTRAQ Flux

Measure the total quantities of Methane and CO2 escaping your site

ReSource International has developed a world-leading method of quantifying and mapping landfill gas emissions using UAVs (drones), which has been demonstrated in recent tests to be accurate compared to controlled releases.

A highly accurate (±0.6ppb) methane sensor is flown on a UAV downwind of the landfill site. Windspeed measurements are taken on the UAV and on the ground, and the result of this can be used to give a precise flux rate after the plume is reconstructed by a software algorithm.

PACK 2: GASTRAQ – UAV Map

Get a concentration map in few minutes

To map emissions sources, the UAV is flown at low altitude (typically 15m if a local topographic model is available) and emissions are algorithmically interpolated to give a map of emissions sources. Sources typically are a short distance upwind of where the UAV first measures the plume. The same gas sensor can be easily dismounted from the UAV and used to trace gas leaks to cm-level precision using a handheld wand. Approximately 200 ha per day could be covered using this approach, depending on density.

PACK 3: GASTRAQ – GROUND Map

Walking survey and leak detection

Because sometimes we cannot replace human beings and their experience (and legs), we are able to also use our equipment on the ground. We will log all measurements just as we do with the UAV so you can use data report to improve your operation and maintain your equipment.
