What Are Type 5 Plastics?

If you've ever turned a plastic container over to check the recycling symbol, you may have noticed a number inside the triangle of arrows. When that number is 5, it means the item is made from polypropylene, commonly known as PP.

Polypropylene is a strong, lightweight plastic that resists heat and moisture, making it a popular choice for a variety of everyday products. You’ll often find it in yogurt cups, microwave-safe food containers, bottle caps, and even some reusable water bottles. Its durability and resistance to high temperatures make it ideal for items that might go from fridge to microwave.

From an environmental standpoint, type 5 plastics are technically recyclable, but availability varies widely depending on where you live. While curbside recycling programs in some areas accept PP, many still don’t due to cost and infrastructure limitations. However, when recycled, polypropylene can be turned into items like automotive parts, industrial fibers, or even urban furniture like park benches.

One thing to keep in mind: just because a plastic is labeled as recyclable doesn’t mean it will be recycled. It’s always a good idea to check with your local waste management provider to see if they accept type 5 plastics. In the meantime, reducing single-use plastics and reusing containers when possible can go a long way.

As awareness grows, more companies are designing products with recyclability in mind, and polypropylene is slowly becoming easier to process. For now, being informed about what that little number 5 means can help you make smarter choices—both for your health and the planet.
