Is PP Recyclable? The Answer May Surprise You!

Are you curious whether polypropylene (PP) is recyclable or not? Many of us may be unaware of what plastics are recyclable and what aren’t. Plastics manufacturing has boomed over the past few decades, and plastic waste has become a major issue across the globe.

It’s becoming increasingly important to reduce and recycle plastic waste, as our planet is overwhelmed with landfills and plastic pollution. In this article, we will discuss whether or not PP is recyclable, providing you with all the answers you need.

What is Polypropylene (PP)?

Polypropylene or PP is a thermoplastic polymer that has become quite popular in recent times. It’s a versatile, lightweight, and durable plastic that is used in manufacturing a wide range of products, including packaging, textiles, lab equipment, automotive, and consumer goods. What’s more, PP is relatively low-cost and can be easily molded and shaped into various forms such as sheets or fibers.

Properties of Polypropylene (PP)

Before we dive deeper into the topic of whether PP is recyclable, it’s important to understand its properties:

  • PP is lightweight, making it ideal for packaging and transportation.
  • PP is highly durable and resistant to heat, water, and chemical corrosion, which makes it ideal for laboratory equipment.
  • It has good insulation and translucent properties, making it ideal for manufacturing textiles and food containers.
  • PP can be easily molded and shaped into different forms.

Is Polypropylene (PP) Recyclable?

The good news is that PP is one of the most commonly recycled plastics worldwide. Many recycling companies and organizations have developed recycling programs to collect and recycle PP products.

PP is recyclable because it’s a thermoplastic material, meaning it can be melted down and reshaped into new products. When recycled, it’s used to produce items like plastic lumber, garden furniture, automotive products, and even textiles.

How is Polypropylene (PP) Recycled?

The recycling process for PP involves sorting, cleaning, and melting down post-consumer waste products. The melted plastic is then extruded into thin string-like fibers, which are further woven or spun into new items. Some companies use a chemical process to convert PP into a liquid form and then further process it into new products.

However, it’s important to understand that like any other plastic, PP cannot be continually recycled indefinitely. The recycling process can cause the loss of some essential properties of the original polymer, making it less suitable for certain applications with each recycling cycle.

Benefits of Recycling Polypropylene (PP)

Recycling PP has numerous environmental and economic benefits:

  • Reducing plastic waste and conserving natural resources.
  • Preventing plastic waste from ending up in landfills and ocean pollution.
  • Reducing the energy needed to create new plastic.
  • Creating new job opportunities in the recycling industry.
  • Lowering the cost of production for companies that use recycled materials.

Recycling Symbol for Polypropylene (PP)

Recyclable plastics are labeled with numbers inside the universal recycling symbol (three arrows in a triangle). The number inside the symbol indicates the resin identification code, which is a system used to identify and recycle specific plastics.

The recycling symbol for PP is number 5, which means that PP products are recyclable, and they should be sorted and recycled separately from other plastics.

Which Polypropylene (PP) Products are Recyclable?

Many PP products are recyclable, such as:

  • PP packaging films and bags
  • PP food containers
  • PP yogurt cups and drink bottles
  • PP automotive parts
  • PP lab equipment
  • PP household items such as toys, storage bins, and furniture.

It’s important to remember that some PP products may still not be recyclable in certain areas. Therefore, it’s recommended to check with local recycling facilities what PP products they can accept and recycle.

What Happens to Unrecyclable Polypropylene (PP) Products?

Some PP products cannot be recycled, such as plastic straws or plastic cutlery. Even though these items are made of PP, they are typically too small to be sorted and recycled effectively.

Unrecyclable PP products should be thrown in the trash, and you should try to reduce your plastic consumption by avoiding single-use products and choosing reusable alternatives.


Polypropylene (PP) is a valuable and versatile plastic that can be easily recycled. Its properties, combined with its low cost, make it a popular choice in various industries. To reduce plastic waste and preserve natural resources, it’s essential to recycle PP products.

Recycling programs and facilities have made recycling accessible and convenient for individuals and businesses. Remember to check with your local recycling center which PP products are recyclable and make the effort to recycle all appropriate plastic products.
