What does a triangle with a 5 in it mean?

Answered by Frank Schwing

The triangle symbol with a “5” inside on a plastic container indicates that the plastic is made of a material called Polypropylene, often abbreviated as PP. This particular symbol is part of a standardized system known as the Resin Identification Code (RIC), which was developed by the Society of the Plastics Industry to help identify different types of plastic.

Polypropylene is considered one of the safer types of plastics, as it has a relatively low risk of leaching harmful chemicals into food or beverages. This makes it a popular choice for various food and beverage containers, such as medicine bottles, ketchup bottles, yogurt containers, and even straws.

One of the great advantages of Polypropylene is its recyclability. When these plastic containers are recycled, they can be transformed into a range of useful products. For example, recycled Polypropylene can be used to make trays, pallets, bins, bicycle racks, and even brooms. This not only helps to reduce the amount of plastic waste in landfills but also conserves valuable resources by giving new life to old plastic.

Personally, I have seen the recycling process of Polypropylene in action. I have visited recycling facilities where plastic containers with the triangle symbol and the number 5 are sorted from other types of plastics. These containers are then cleaned, shredded, and melted down to create new Polypropylene pellets. These pellets can be used as raw material for manufacturing various products, providing a sustainable and environmentally-friendly solution.

It is important to note that while Polypropylene is recyclable, not all recycling programs accept all types of plastics. It is essential to check with your local recycling facility or municipality to see if they accept Polypropylene or plastics with the number 5 symbol. If they do, be sure to rinse and remove any caps or lids from the containers before recycling them to ensure the process is as efficient as possible.

The triangle symbol with a “5” inside on a plastic container signifies that the plastic is made of Polypropylene. Polypropylene is a safer type of plastic and can be recycled into a variety of useful products, helping to reduce waste and conserve resources. By recycling these plastic containers, we can contribute to a more sustainable and environmentally-friendly future.
