Have you ever wondered what the numbers on the bottoms of your plastic bottles stood for?  There are many different types of plastics!  Each number refers to a different type of plastic material.  We accept plastics #1-7 on recycling day.

Different Plastic Recycling Terms:

  • Plastic#1 – PET – Polyethylene Terephthalate is commonly used to make 2 liter soda bottles.  It’s the most widely recycled plastic!
  • Plastic #2 – HDPE – High Density Polyethylene is used to make detergent bottles, milk jugs, and more.
  • Plastic #3 – PVC – Polyvinyl chloride is used to make plastic pipes, outdoor furniture and water bottles.
  • Plastic #4 – LDPE – Low Density Polyethylene is used to make produce bags, trash can liners, and food storage containers.  While we do not accept plastic bags, we do accept containers that are made from LDPE.
  • Plastic #5 – PP – Polypropylene plastic is used to make drinking straws and aerosol caps.
  • Plastic #6 – PS – Polystyrene plastic is more commonly known as styrofoam.  It is used in packaging pellets, cups, clam shell containers.
  • Plastic #7 – These plastics are any plastics that do not fall into the #1-#6 category.  they tend to be food containers, tupperware and other plastics.
