The project is located at the outer banks of the Connecticut River and clean surface water runoff produced with the ClosureTurf®  system greatly reduced potential environmental impacts to the river and enhanced water quality discharge.

MIRA Hartford culminated the final phase of the Hartford Landfill closure with a 35-acre cap utilizing ClosureTurf®, a revolutionary three component closure system, topped by five acres of solar panels. After a 73 year existence as an “eyesore,” the state-owned landfill is now an example of innovation in renewable energy for future landfill closures in Connecticut and across the nation.

The complexity of designing plans for closure—and the subsequent impressiveness of its successful completion— existed in finding a landfill closure system with a membrane compatible to installing solar PV panels atop the turf. CRRA reviewed various closure systems to identify a product membrane best suited for its specific needs.

In addition to these benefits, CRRA ultimately chose ClosureTurf®  over other options for the following specific components, according to the State’s closure review summary:

  • Ability to be walked on or driven across by light rubber tire vehicles without product damage
  • Repair options that cost significantly less than comparable systems
  • Aesthetically superior to competitor closure systems
  • A membrane with an overall proven track record in landfill closure applications

With the completion of the installation, the Hartford Landfill is now the first in the state of Connecticut—and one of few in the nation— to be transformed into a renewable energy source through the generation of solar power.

Collected energy will be sold to the regional power grid in Connecticut. The CRRA plans to generation enough megawatts to power more than 1,000 Hartford homes. When the closure project is completed, the entire 96 acre landfill will be encapsulated with ClosureTurf® .

“When we began working with the City of Hartford on the future of the landfill, we wanted to find innovative ways to use the land. Solar energy was an idea we all agreed on right away.”
