We developed a complete range of services around greenhouse gas monitoring and reporting, we call it GASTRAQ. It stands for Gas Tracking and Quantification.  We know that the requirements and possibilities are different for each case, so we offer 3 different packages that can be combined in order to fit best your needs. 

These kinds of services are quite specific, so we encourage you to contact us in order to discuss the potential and how we could help you the best. All our deliveries are compatible with the platform eLandfill, so it is easier for you to visualize and share results in your own organization.

GASTRAQ

Ground-based mapping

Walking surveys, hotspots map and leak detection

Drone-based mapping

Get CH4/CO2 concentration map in few minutes

Total flux

Measure total fluxes of CH4 and CO2 per site                     

PACK 1: 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.

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 – Total Flux

Measure the total quantities of CH4 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.
