Landfills are some of the largest methane emitters in the world - but there has not been an easy way to monitor them. Until now.

Landfills are living, breathing assets.

But satellite snapshots and drone flyovers only provide mere glimpses into what’s happening above and under the ground.

TrelliSense’s proprietary platform was designed to measure methane emissions continuously across entire landfills. We can give you unprecedented visibility into the emissions behavior of your landfills, gas collection systems and gas processing facilities.

New open-source tools such as NASA’s EMIT Open Data Portal are providing more and more emissions “snapshots” to industry and the general public - bringing transparency to super-emitters.

The TrelliSense platform is:

Long-Range

Because our sensors look up at the sun, they can monitor landfills of all shapes and sizes - no matter how hilly.

Effective

Our path-integrated measurements can quantify methane at sub-ppm concentrations - and localize leaks down to the wellhead.

Easy to Use

Solar power & IoT communication mean continuous monitoring with no power requirements or interruptions to landfill operations.

Affordable

Modular, passively powered and mountable anywhere, our sensors cost just a fraction of other path-integrated options.
