Car Seats See Alternatives Take to Landfill Alternative Ways to Recycle No Accidents, Not Expired? Donate You can donate a car seat, but only if it has never been in an accident, if it has not expired, and if the straps haven’t been chemically cleaned. Some donation centers will not accept car seats, so look for organizations that provide family services, like women’s shelters. Did You Know? The Damage Is There, Even When You Can't See It Car seat expiration dates (or 6 years, if unmarked) shouldn’t be overlooked. Even if the car seat doesn’t look damaged, the materials it’s made out of degrade over time, especially with regular exposure to UV light through car windows. Be careful when buying used: only accept a used car seat from someone you know and trust. Safe Trumps Green When buying a car seat, green isn’t always best. Experts don’t recommend buying used, even though it’s greener than buying new. Organic seat covers won’t shield your child from the toxic leaching of flame-retardant materials, either.
