What Is Type 5 Plastic?

When you're sorting your recycling, you might notice a number "5" inside the recycling triangle on certain containers. That symbol means the item is made of polypropylene, commonly known as type 5 plastic. This material strikes a balance between flexibility and durability, making it a popular choice for a variety of everyday household items.

You’ve likely encountered type 5 plastic without even realizing it. Think of those clear, rigid "clamshell" containers that hold berries or salad greens at the grocery store—those are often made from polypropylene. Yogurt cups, butter tubs, and screw-on bottle caps are other common examples. Thanks to its resistance to heat and moisture, polypropylene is especially well-suited for packaging food.

While not all recycling programs accept type 5 plastic, many do—especially curbside programs that have expanded their capabilities in recent years. Still, it’s always a good idea to check with your local waste management authority. When accepted, these plastics are often turned into items like plastic lumber, car battery cases, or even new containers.

One of the benefits of polypropylene is that it’s relatively stable and less likely to leach harmful chemicals, making it a safer option for food storage. However, like all plastics, it’s best used mindfully. Reusing containers when possible and recycling them properly helps reduce waste and environmental impact.

So next time you finish a tub of yogurt or a takeout salad, take a quick glance at the bottom. If you see a "5", you’ll know it’s made of polypropylene—and with the right local facilities, it might just get a second life after all.
