Avantium’s plant-based PEF plastic secures approval  in Japan’s PET bottle network

JAPAN – Dutch polymer innovator Avantium has achieved regulatory clearance for its renewable polyethylene furanoate (PEF) material, known as releaf, to enter Japan’s established polyethylene terephthalate (PET) recycling infrastructure.

According to industry observers, the approval from the Council for PET Bottle Recycling (CPBR) allows releaf to integrate into the PET stream at concentrations reaching 10% by weight without disrupting operations. 

This development opens doors for releaf’s use in beverage bottles, targeting Japan’s vast market for sustainable containers.

The CPBR, which guides nationwide initiatives to enhance PET container recovery, conducted a thorough evaluation of releaf as a barrier layer in multilayer PET structures. 

Their findings confirmed the material’s compatibility, noting it maintains process efficiency and output quality during mechanical recycling.

In a detailed assessment, the council awarded bottles incorporating PEF an A-grade recyclability score, affirming their fit for closed-loop bottle-to-bottle reuse. 

Releaf, derived from Avantium’s proprietary YXY process using plant-based feedstocks, satisfied rigorous tests on physical properties, chemical stability, and handling in recycling facilities.

The material also adheres to Japan’s Positive List for plastics in food contact, alongside guidelines from the Ministry of Health, Labour and Welfare. 

It meets parallel requirements under U.S. Food and Drug Administration rules, ensuring broad applicability for global supply chains.

This Japanese endorsement builds on earlier validations for PEF recyclability. 

In Europe, the PET Bottle Platform issued similar positive evaluations, while the Association of Plastic Recyclers in the United States confirmed its performance in North American systems.

Yuzhong Chen, Avantium’s business development manager for Asia, expressed gratitude in a statement: “We sincerely thank all the companies in Japan that supported Avantium during the CPBR assessment.”

“Their collaboration was vital in demonstrating that releaf can be successfully recycled within Japan’s PET bottle stream while preserving high material quality.”

Chen added that the partnership highlighted a collective push toward plant-derived packaging that supports recycling goals.

The clearance arrives amid Avantium’s expanding collaborations. Earlier this year, in February 2025, the company entered a joint development pact with Amcor Rigid Packaging USA. 

Under the agreement, the partners aim to integrate releaf into rigid packaging formats, focusing on enhanced barrier properties for longer shelf life in beverages and other products.

A report by CPBR emphasized that such innovations could accelerate Japan’s shift to bio-based alternatives, given the country’s annual recycling of over 2 million tons of PET bottles. 

With releaf’s low carbon footprint, derived from renewable sources like agricultural waste, the material offers a practical path to reduce reliance on fossil fuels in packaging.

Avantium plans to scale production at its upcoming facility in the Netherlands, with initial output targeted for commercial trials in Asia by late 2026. 

Industry experts anticipate this approval will spur trials with Japanese bottlers, potentially expanding releaf’s footprint in carbonated drinks and water segments.

As global pressure mounts to phase out virgin plastics, Japan’s decision provides a blueprint for harmonizing new materials with legacy systems. 

For beverage giants operating in the region, this means viable options to meet tightening sustainability mandates without overhauling recycling lines.
