Think twice before stuffing a package with Styrofoam peanuts. They aren't recyclable.

Simran says people often assume that everyday items can be recycled, but many will end up in a landfill. Broken glass, lightbulbs, ceramics, Styrofoam, Pyrex, some yogurt containers, aerosol cans, soiled boxes and anything covered in wax paper are not recyclable.

"You really want to be careful with your consumption. Just thinking about, 'Okay, if we know this is going to end up in a landfill, why don't we get a bigger container so we're not putting so many little containers in the landfill,'" Simran says. "There are ways to be smart about this, even though we can't be perfect."

Simran suggests returning Styrofoam peanuts to packaging companies and bringing your own containers to restaurants when you're ordering take-out.
