Each year, Americans produce over 200 million tons of solid waste, most of which ends up in landfills. It can be challenging to know what to recycle and what to throw away, but it is very important not to mix them up. We’re here to help make sure you know how to correctly dispose of your most tricky trash and risky recycling items.


  • BLACK PLASTIC- Plastic items are sorted by optical scanners which use the reflection of light to identify the types of plastics. Black plastic doesn’t reflect light, so cannot be seen and sorted by the scanners and could end up contaminating other materials such as glass bottles.
  • PLASTIC UTENSILS- These are made of the same resin used to make polystyrene foam and labeled #6 which is not recyclable.
  • FREEZER BOXES- With freezer boxes, it is impossible to remove the plastic from the paperboard, and most municipalities cannot accept this plastic into their recycling stream.
  • STYROFOAM- Styrofoam is made of foamed polyesterene and the technology to recycle this material is not practical, so it has to go in the trash.


  • YOGURT CONTAINERS- Most yogurt containers are recyclable as long as they are clean!
  • POST-IT NOTES- Post-its are made of paper, and even though they have a sticky backing can still be recycled.
  • ENVELOPES WITH TRANSPARENT WINDOW- Even with the plastic window, paper envelopes are recyclable!
  • PLASTIC CLAMSHELLS- As long as they are not black or Styrofoam, clear plastic clamshells can be recycled.
  • COLORFUL PAPER- You can recycle most paper, even if it is glossy or colored.
