Hartford landfill officially closes after 75 years

Ten months after its final capping project was complete, the Hartford landfill was declared officially closed in March after 75 years of service.

The Connecticut Department of Energy & Environmental Protection notified landfill operator Materials Innovation & Recycling Authority that the synthetic cap on top of the landfill meets state and federal regulations, officially making the $30.4 million closure project complete. The installation on the cap was complete in June.

The landfill opened in 1940 as an open-burning dump and then as an incinerator from 1953 to 1977. Following a lawsuit from the town of East Hartford over the smoke, the Connecticut Resources Recovery Authority took over operations in 1982 and began operating a trash-to-energy plant. The ash from the plant was deposited in the landfill, which received its final delivery on Dec. 31, 2008.

The four-phase capping project began in 2008 and finished last year, including installing 3,993 solar panels that can generate electricity to power 1,000 homes.
