Life: Sustained

Innovation at a landfill,
who knew?
Hartford, Connecticut

You wouldn’t normally associate “creating works of life” at a landfill, but that’s exactly what we did for the City of Hartford. Our engineers developed an innovative approach to cap 35 acres of landfill with a state-of-the-art synthetic capping system that looks like natural grass. This capping system, which was a first in New England, is topped by a solar photovoltaic electric generation system comprised of approximately 4,000 solar cells – producing enough electricity to power 1,000 homes when operating at full capacity.

In addition to working closely with the City of Hartford and the Materials Innovation and Recycling Authority, internal collaboration was required between our civil engineering, stormwater management, structural engineering, and electrical engineering teams. As the engineering consultant on this project, we were responsible for landfill closure design and permitting, as well as requesting and receiving approval of the pioneering capping system by the Connecticut Department of Energy and Environmental Protection.

Practice Areas Involved:


This aesthetically pleasing synthetic cap encapsulates approximately 10 million tons of waste within the Hartford Landfill and adds value to the community by turning an unattractive municipal element into an additional power source.  The project exemplifies sustainability by offering the dual benefit of closing and capping the landfill in a sustainable way, while solar cells generate clean, renewable energy.
