A 1.6 MW Caterpillar 3520 generator uses methane gas from the Denton Landfill to generate power while a backup candlestick flare located on the landfill property combusts landfill gas when the generator is at capacity.

The Denton landfill site is approximately 243 acres, of which 152 acres are designated as the waste footprint area. The City of Denton has operated the landfill since 1984, but before 2008 never had a comprehensive gas collection system in place.

Methane emissions from landfills in the U.S. represent approximately 34% of total U.S. anthropogenic methane pollution, and The City of Denton Landfill is not currently required to install a gas collection and control system.

Although the landfill’s capacity makes it subject to review for New Source Performance Standards, the landfill’s measured non-methane organic compound emissions are below a level at which installation of a collection system is required. 

The facility monitors gas flow using flow meter readings and periodic methane content samples to verify the amount of methane captured and combusted. The emission reductions are verified by an accredited third-party verifier using the Climate Action Reserve’s Landfill Project Protocol. The Climate Action Reserve is a Green-e Climate Endorsed independent third-party greenhouse gas (GHG) Project Certification Program.

All carbon offsets generated by the verified emission reductions are registered by the Climate Action Reserve and receive a unique serial number. This ensures that the carbon offsets are not double counted and, once retired, are not sold or transferred again.

3Degrees offers purchasers the option to buy Green-e Climate certified carbon offsets sourced from this project.
