The Lower Connecticut River Valley Council of Governments (RiverCOG) will be holding a series of household hazardous waste (HHW) collection events in our area on select Saturdays from April through October.  Lyme residents are encouraged to use any or all of these events to dispose of their HHW materials. To see or download the RiverCOG brochure that lists the dates and locations of the 2023 HHW collection events, as well as a list of HHW items that can be disposed of at these events, click here.
