What Is rPET?

rPET is one of the most widely used recycled materials in packaging today. If you have seen a bottle labeled with recycled content or a sustainability claim, there is a good chance it was made with rPET. This guide explains what rPET is, how it is made, and why it matters for brands moving toward more circular packaging.

What Is rPET?

rPET stands for recycled polyethylene terephthalate. It is PET plastic that has been collected from post-consumer products and reprocessed into new resin. The most common source is used beverage bottles such as water bottles, soda bottles, and other PET containers.

rPET and virgin PET are the same polymer. The difference is the source. Virgin PET is produced from petroleum-based feedstock. rPET is produced from previously used PET that has been sorted, cleaned, and reprocessed.

How rPET Is Made

The recycling process that produces rPET involves several steps. After consumers place PET bottles in recycling bins, the material is collected and transported to a materials recovery facility. There it is sorted by resin type and color. The sorted PET is then shredded into small flakes, washed to remove contaminants such as labels and adhesives, and dried.

The clean flakes are melted and extruded into pellets. These pellets are the raw material that packaging manufacturers use to produce new bottles, containers, and other products. For food-contact applications, the reprocessing must meet additional purity standards set by regulatory agencies.

What Is rPET Used For?

rPET is used across a wide range of applications:

• Beverage bottles and water bottles
• Personal care packaging such as shampoo and lotion bottles
• Food containers and jars
• Polyester textile fibers for clothing and carpets
• Packaging films, strapping, and industrial materials

Its versatility makes rPET one of the most commercially practical recycled materials. It works with existing bottle molds and filling equipment, which makes it a drop-in solution for brands switching from virgin plastic.

Is rPET Sustainable?

Using rPET reduces demand for virgin plastic derived from petroleum. It also requires significantly less energy to produce. Studies from the recycling industry estimate that producing rPET uses approximately 79 percent less energy than producing virgin PET from petroleum feedstock.

rPET supports circular packaging systems by keeping PET material in use across multiple product cycles rather than sending it to landfill after a single use. Many large consumer goods companies have set minimum recycled content targets, and rPET is frequently used to meet them.

Frequently Asked Questions

What does rPET stand for?

rPET stands for recycled polyethylene terephthalate. It is PET plastic made from post-consumer recycled bottles and packaging rather than virgin petroleum feedstock.

Is rPET the same as regular PET?

Yes. rPET and virgin PET are the same polymer. They share the same chemical structure and similar physical properties. The only difference is the source of the resin.

What is the recycling symbol for rPET?

rPET bottles use resin identification code 1, the same as virgin PET. The code appears as a triangle with the number 1 inside, often labeled PET or PETE. There is no separate code that distinguishes rPET from virgin PET.

How do I know if a bottle is made from rPET or virgin PET?

You cannot tell from the bottle itself. Both look identical when processed to the same grade. To verify rPET content, request a recycled content certificate or certificate of analysis from your supplier specifying the percentage of post-consumer recycled material.
