Applicances with CFC/Freon

All batteries can be brought to a DSNY SAFE Disposal Event or to any DSNY Special Waste Drop-Off Site for recycling. Alkaline batteries are no longer classified as harzardous in New York State, but it is more environmentally friendly to bring them to a drop-off site instead of discarding in the regular garbage.
It is illegal to discard rechargeable batteries in the garbage or regular recycling. In New York State, most stores that sell rechargeable batteries, including pharmacies, and office supply and hardware stores, will accept them free of charge. Ask for the “Call2Recycle box”.
