Common Items We Are Asked About - 

Alkaline Batteries

Alkaline batteries (regular household batteries) can be brought to the Household Hazardous Collections for recycling. Alkaline batteries do not contain mercury but can be recycled through the collections. Alkaline batteries can also be brought to the Recycling Center (in the electronics container) or the 2nd floor of City Hall for recycling. 

Fire Extinguishers

Fire extinguishers can be brought to:
Roybal Fire Equipment
33 Forest Street
Middletown, CT
Phone: 860-347-2189

Fluorescent Bulbs

Most fluorescent bulbs also contain mercury and should be disposed of properly. Compact fluorescent bulbs can be brought to Home Depot or Lowes for recycling. The Middletown Recycling Center and Russell Library also accept them. Long fluorescent tubes from residences can also be brought to the Recycling Center or to a Household Hazardous Collection Day for safe disposal.


Latex and oil-based paint can be brought to the Household Hazardous Waste Collection day. Unopened cans of latex paint can be donated to non-profit organizations, such as Oddfellows Playhouse or Habitat for Humanity. Check with the local organization for acceptance and drop off instructions. 

The State of Connecticut passed Public Act 11-24, An Act Establishing a Paint Stewardship Program, in 2011. This legislation establishes a paint stewardship program for managing unused and unwanted latex and oil based paint. In accordance with this Act, Ace Hardware on South Main Street and Sherwin Williams Paint Store on Route 372 in Cromwell have initiated programs to take back oil based and latex paint for recycling. Contact these stores directly for their specific requirements for drop off. For more information on paint recycling, check out the PaintCare website.

Unused Medication

Unused medication should not be flushed down the drain.  EVER.  The Middletown Police Department offers an unused medication drop off in its lobby or the Middletown Health Department offers unused medication disposal bags.   

You can also watch for a Drug Take Back Day, which is held in various locations in April and October. 

More information can be found here.  

Waste Oil 

Waste Oil is not accepted at the City Recycling Center.  In 2018, it was contaminated with PCB's and it was very costly to remove and dispose properly.   Waste oil is accepted at the Household Hazardous Waste Collections or can be brought to some local retailers (PDF) for recycling.
