15 Things You Should Never Throw in the Recycling Bin

But that doesn't mean they need to end up in landfills.

Light bulbs

CFLs, fluorescents, and other light bulbs contain mercury, so you can’t throw them in with the rest of your recyclables—or your trash can. In fact, it’s actually illegal in some states to put CFLs in your trash. Instead, they’ll need to go to a recycling center equipped to dispose of the toxic chemicals safely. Visit to find out where drop-off locations are or when pickup services come to your area. Try these other 25 ways to reduce your carbon footprint.

Don’t toss broken bakeware out with your jars. Because glass like Pyrex is treated to survive high temperatures, it also won’t melt down correctly with the rest of your glass. Wrap it up so broken glass can't hurt sanitation handlers, then place the glass in your trash.

Drinking glasses

Like Pyrex, glasses are treated with chemicals that help them withstand both hot and cold temperatures, meaning their melting point is higher. Because they won’t melt correctly with your typical glass jar, they mess up the recycling process for other types of glass. Wrap them in paper to contain any shards, then leave them in the trash.

Unlike glass, ceramics can’t melt down to be recycled. But that doesn’t mean your old mugs need to sit in a landfill. If they’re still in good condition, donate them to a thrift store. There are other options if they’re chipped, though; they can be crushed down for concrete, gravel, and retaining walls, and more. Check to see if there are any drop-off spots near you; some places that accept brick and concrete might also take ceramics off your hands. If not, some artists will take them for use in mosaics and other projects. Just don't give away these things you should never donate to thrift stores.

Wire hangers can get caught in recycling machinery, but they can often go to scrap metal businesses equipped to deal with the wiry shapes. Meanwhile, it’s hard for disposal centers to know what type of plastic others are made of, so they’re forced to trash those, too. Follow the other two R’s: reduce and reuse. Don’t take plastic hangers home from the clothes store if you don’t plan to use it, and donate your extra hangers to a thrift store. This is what recycling will look like in 10 years!

Styrofoam containers

Actually, there’s no such thing as a “Styrofoam” cup. The trademarked name for polystyrene is only used for insulation and craft projects, and the foam used in coffee cups and egg cartons is expanded polystyrene. On, see if there’s a recycling center that will accept #6 plastic polystyrene, then call to confirm they’ll take items like egg cartons and takeout containers, which many won’t.

Packing peanuts

Like other foam products, you’ll have a tough time finding anywhere that will take your old packing peanuts. Your best bet is to reuse them the next time you send a package, or call up local shipping centers to see if their business can use them. Here are more bizarre things you didn't know you could donate.

A “looking glass” isn’t as easy to recycle as most glass. A reflective coating helps mirrors do their jobs, but that treatment also makes it hard for recyclers to break them down. If it’s in decent condition, sell or donate an old mirror. For broken ones, see if any artist groups in your area are collecting mirrors as scraps for use in their projects.

Half-full aerosol cans

Anything left in an aerosol can is considered hazardous waste (yes, including whipped cream and hairspray), so make sure it’s empty first. Check your local recycling center to make sure they take empty aerosols—some consider even empty cans hazardous. If yours does accept them, remove the plastic cap before tossing it in the recycling bin.

Plastic bags

Nearly every household has a “bag of bags,” but don’t empty your extras into the recycling bin when it gets to full. While plastic bags are recyclable, most facilities only have the means to deal with rigid plastics, like bottles and coffee lids. Visit to find a drop-off spot near you.
