Food-grade vs non-food-grade rPET: What brands must know before procurement

It usually starts with a simple goal.

A brand wants recycled plastic in its packaging. Procurement begins speaking to suppliers. A few batches of rPET flakes arrive for evaluation.

And then someone asks the question that changes the entire discussion. “Can this even go back into a bottle?”

That is usually the moment when the conversation becomes uncomfortable. Because while many suppliers sell rPET, not all of it can be used in food or beverage bottles.

And if a brand gets this distinction wrong, the consequences are far from minor. Compliance risks, packaging failures, and supply disruptions can follow.

So, before any purchase order is signed, brands need to clearly understand one basic thing: food-grade rPET and non-food-grade rPET are not the same material, even if they look identical.

If all rPET comes from bottles, why can’t it all go back into bottles?

Most rPET starts its life as a PET bottle. After use, these bottles are collected, sorted, cleaned, and recycled.

But the journey from waste bottle to new bottle is not simple.

During collection and recycling, plastic can pick up contaminants. These may come from labels, other plastics, food residue, chemicals, or even the environment where the waste was stored.

For recycled plastic to be used again in food or beverage packaging, those contaminants must be removed to extremely strict levels.

That is why regulators worldwide require special recycling processes for food-grade rPET.

According to the Food Safety and Standards Authority of India (FSSAI) and the Bureau of Indian Standards (BIS), recycled PET used in food packaging must undergo validated decontamination processes that remove potential contaminants to safe levels.

Without this step, recycled PET cannot legally or safely be used for food packaging.

So what actually makes rPET “food-grade”?

Food-grade rPET is not simply recycled plastic. It is recycled plastic that meets strict safety and traceability standards.

To produce bottle-to-bottle material, recyclers must control the process from start to finish.

Key requirements usually include the following:

• Controlled feedstock, primarily post-consumer PET bottles
• Advanced washing and sorting systems
• Super-clean recycling technology that removes contaminants
• Regulatory compliance with food-contact standards
• Traceability of the waste stream

In India, compliance with Bureau of Indian Standards (BIS) guidelines is critical for food-contact recycled plastics.

These standards ensure that the rPET flakes or pellets produced are safe for reuse in beverage bottles and food packaging.

Without these safeguards, recycled PET may still be useful. But it cannot be classified as food grade.

Then, where does non-food-grade rPET go?

A large portion of recycled PET globally is actually non-food-grade rPET.

This material still has value. It simply serves different industries.

Common applications include:

• polyester fibre used in textiles
• packaging straps
• thermoformed trays
• plastic sheets and industrial packaging

Because these uses do not involve direct food contact, the contamination thresholds and regulatory requirements are different.

According to a study, only a portion of recycled PET is processed through systems designed for bottle-to-bottle recycling. The rest flows into these non-food applications.

For brands that need recycled content in beverage bottles or food packaging, this distinction matters greatly.

Why procurement teams often struggle with rPET sourcing

On paper, sourcing rPET looks like a straightforward procurement exercise.

In reality, it is tightly linked to the entire recycling ecosystem behind the material.

Many brands focus only on price and material specifications when evaluating suppliers. But food-grade recycled PET depends on factors that sit much earlier in the chain.

Questions procurement teams often overlook include:

• Where were the bottles collected from?
• How were they sorted and processed?
• Is the recycling process validated for food contact use?
• Is the material traceable back to post-consumer PET bottles?

Without clear answers, brands may unknowingly purchase material that cannot legally or safely be used in food packaging.

That is why leading companies are starting to look beyond suppliers and examine the systems that produce the rPET in the first place.

The quality of rPET starts long before recycling

High-quality rPET does not begin inside a recycling plant.

It begins with the collection system.

If the incoming PET bottles are poorly sorted, heavily contaminated, or mixed with other plastics, even the best recycling technology struggles to produce food-grade material.

This is why strong recovery networks, efficient sorting infrastructure, and transparent supply chains play such a critical role in bottle-to-bottle recycling.

In other words, the quality of the recycling ecosystem determines the quality of the rPET it produces.

Building the system behind reliable food-grade rPET

At ReCircle, the focus is not just on supplying recycled material. The focus is on building the system that enables high-quality rPET.

Through a pan-India recovery network, ReCircle works with collection partners to recover post-consumer PET bottles. These bottles are sorted and processed through traceable supply chains designed to support bottle-to-bottle recycling.

The result is high-quality food-grade rPET flakes produced from post-consumer PET bottles.

These flakes are:

• suitable for bottle-to-bottle applications
• fully traceable across the supply chain
• compliant with BIS standards

For brands looking to increase recycled content while maintaining packaging safety and regulatory compliance, this system-first approach matters.

Looking to procure food-grade rPET?

Demand for recycled packaging will only continue to grow, but sourcing the right rPET requires transparency and strong recycling infrastructure.

ReCircle’s pan-India recovery network collects post-consumer PET bottles and converts them into traceable, BIS-compliant bottle-to-bottle rPET flakes suitable for food and beverage packaging.

If your brand is planning to increase recycled content in packaging, connect with the ReCircle team to explore procurement options and secure a consistent supply of food-grade rPET.
