Is PETE 1 Recyclable? How It Works and Rates

Yes, PETE 1 (polyethylene terephthalate) is recyclable and is one of the most successfully recycled plastics in the world. It’s the clear plastic used for water bottles, soda bottles, peanut butter jars, salad dressing containers, vegetable oil bottles, and mouthwash bottles. If you see the number 1 inside the triangular recycling symbol on the bottom of a container, it’s PETE, and nearly every curbside recycling program in the United States accepts it.

Why PETE 1 Is Easy to Recycle

PETE has a few properties that make it stand out among plastics. It’s a single-layer, single-material plastic with good barrier properties, meaning it doesn’t need to be laminated with other materials the way many food packages are. That mono-material composition is key: when a plastic is made of just one type of polymer, recycling facilities can melt it down cleanly without having to separate bonded layers. Multi-material packaging, by contrast, is a recycling nightmare.

PETE is also a thermoplastic, which means it can be melted and reshaped repeatedly without losing its fundamental structure (at least for a number of cycles). This makes it a strong candidate for “closed-loop” recycling, where a bottle becomes another bottle rather than being downcycled into a lower-value product.

How PETE 1 Gets Recycled

The mechanical recycling process for PETE is straightforward compared to other plastics. Collected bottles are first ground into small flakes, then washed with water to separate the PET from labels, adhesives, and other non-PET materials. The flakes are dried, melted, and extruded into pellets, which manufacturers then use as raw material.

For recycled PETE destined for food packaging, there’s an additional decontamination step. Some facilities use a chemical wash with sodium hydroxide solution after the standard water wash, which strips away surface-level impurities. This “super-clean” process is what allows recycled PETE to meet the safety thresholds set by the FDA and the European Food Safety Authority for direct food contact. Both agencies use a challenge test that deliberately contaminates plastic with worst-case substances and then measures how effectively the recycling process removes them.

What Recycled PETE Becomes

Recycled PETE (often labeled rPET) flows into several industries. In 2017, 47 percent of all available rPET in the United States went into fiber products: carpet, clothing, shoes, and fiberfill for jackets and pillows. The rest went into new beverage bottles, clamshell food containers, trays, cups, strapping material, and plastic sheeting.

You’ve likely encountered rPET without realizing it. Many athletic wear brands use recycled bottle fiber in their polyester fabrics. Food-grade rPET pellets go back into new water and soda bottles, completing a true bottle-to-bottle loop. If you want to support the system, look for products that advertise rPET content on their labels.

The Actual Recycling Rate

Here’s where the picture gets less rosy. Just because PETE is recyclable doesn’t mean most of it gets recycled. The U.S. PET bottle recycling rate was 30.2 percent in 2024, down slightly from a peak of 32.5 percent in 2023. The broader North American collection rate (which includes bottles gathered but not yet processed) was 39.2 percent.

That means roughly 60 to 70 percent of PET bottles sold in the U.S. still end up in landfills or the environment. The gap isn’t a materials problem. It’s a collection and sorting infrastructure problem. States with bottle deposit laws consistently see higher return rates than states without them.

New Laws Requiring Recycled Content

Legislation is starting to push the demand side of the equation. As of 2025, five U.S. states have passed laws requiring minimum recycled content in plastic packaging. California now requires beverage bottles to contain at least 25 percent post-consumer recycled plastic. Washington state requires 25 percent recycled content in beverage bottles starting in 2026, and already requires 15 percent in household cleaning products and trash bags. Maine will follow with a 25 percent requirement for beverage containers in 2026.

These mandates create guaranteed demand for rPET, which in turn makes collection and processing infrastructure more economically viable. When manufacturers must buy recycled material, the economics of recycling improve across the entire chain.

How to Recycle PETE 1 Properly

The simplest thing you can do is empty the container, give it a quick rinse, and toss it in your curbside recycling bin. You don’t need to scrub it spotless. A brief rinse removes enough food residue to prevent contamination of the recycling batch.

Contamination is a real concern for recyclers. When bottles that originally held non-food products (cleaners, automotive fluids, personal care items) get mixed into the recycling stream alongside food-grade bottles, they can introduce chemical residues that complicate the decontamination process. The super-clean recycling methods used for food-grade rPET are designed to handle worst-case contamination scenarios, but keeping obviously dirty or chemical-filled containers out of the bin helps the system work more efficiently.

Most recycling programs now ask you to leave caps on. The caps are typically made of a different plastic (polypropylene, number 5), but modern sorting equipment separates them during processing. Loose caps, on the other hand, are small enough to fall through sorting screens and jam machinery.

PETE 1 vs. Other Plastics

Not all recycling numbers are created equal. While PETE 1 and HDPE 2 (the opaque plastic in milk jugs and detergent bottles) have well-established recycling markets, plastics numbered 3 through 7 are far harder to recycle and often lack viable end markets. Many curbside programs technically accept them but end up landfilling them anyway.

If you’re trying to make better choices at the store, PETE 1 containers are among the safest bets for actually getting recycled into something useful. The combination of widespread curbside acceptance, established processing infrastructure, and strong demand from fiber and packaging manufacturers makes PETE the closest thing the plastics world has to a functioning circular system.
