Numerous communities benefit from the waste disposal and energy generating services provided by the Southeastern Connecticut Resource Recovery facility in Preston, Connecticut. The facility opened in 1991 and will provide a minimum of 25 years of municipal solid waste disposal service to towns comprising the Southeastern Connecticut Regional Resources Recovery Authority.

The facility receives waste six days a week and processes 689 tons of municipal solid waste daily. The plant sells electricity generated beyond its internal operating consumption to Connecticut Light and Power, reducing disposal costs and returning the power generated to CL&P's grid.
