Plant-based recyclable plastic -Avantium’s Plant-Based Releaf Plastic Gains Japanese CPBR Recycling Approval, Paving the Way for Fully Recyclable PET Bottles and Eco-Friendly Packaging Innovation 20-11-2025
Plant-based recyclable plastic
The demand for sustainable and recyclable packaging is growing rapidly, and Avantium is leading the way with its plant-based plastic, releaf. Recently, Avantium announced that releaf has earned recycling approval from the Council for PET Bottle Recycling (CPBR) in Japan. This milestone confirms that the polyethene furanoate (PEF) material can safely enter the Japanese PET bottle recycling stream, marking a significant step toward more eco-friendly packaging.

Avantium’s releaf is produced using its proprietary YXY Technology, which converts renewable plant-based sugars into PEF. This material offers a renewable alternative to conventional plastics while maintaining the strength, barrier properties, and clarity required for food and beverage packaging. The CPBR approval ensures that releaf can be integrated into multilayer PET bottles without disrupting existing recycling systems. Plant-based recyclable plastic
The Council for PET Bottle Recycling, or CPBR, is Japan’s leading industry body responsible for promoting and evaluating PET bottle recycling. The organization sets voluntary design guidelines for PET bottles and rigorously tests new materials to ensure they are compatible with Japan’s advanced recycling infrastructure. Without CPBR approval, new materials cannot be incorporated into the Japanese PET bottle recycling stream, highlighting the significance of this achievement for Avantium.
Avantium collaborated closely with Japanese partners during the CPBR evaluation process. These partnerships were instrumental in demonstrating that releaf can be recycled within the PET bottle stream while maintaining high material quality. According to Avantium, the joint effort reflects a shared commitment to developing plant-based, recyclable packaging solutions that meet both environmental and industry standards.

CPBR’s assessment focused on the use of releaf as a barrier layer in multilayer PET bottles. The evaluation confirmed that the material could be safely and effectively recycled within the existing PET stream at concentrations up to 10% by weight. Releaf passed comprehensive physical, chemical, and processability tests, ensuring its durability and compatibility throughout the recycling process.
Additionally, releaf complies with Japan’s Positive List system for food contact plastics, as well as the Standards and Criteria for Foods and Additives issued by the Ministry of Health, Labour and Welfare. The material also meets U.S. FDA regulations, making it suitable for international applications in food and beverage packaging. CPBR assigned the material an overall recyclability rating of “A,” indicating full compatibility with bottle-to-bottle recycling systems.
This approval has far-reaching implications for sustainable packaging. Multilayer PET bottles that incorporate up to 10% releaf can now be recycled without compromising the efficiency or quality of Japan’s PET recycling stream. Brands adopting plant-based recyclable plastic can reduce their reliance on fossil-based materials, lower carbon footprints, and contribute to circular economy initiatives.
For consumers, the approval ensures that PET bottles containing releaf remain fully recyclable, aligning with the growing demand for environmentally responsible packaging. By combining plant-based innovation with proven recyclability, Avantium’s PEF material addresses both sustainability goals and practical industry requirements. Plant-based recyclable plastic
The partnership between Avantium and Japanese PET recycling stakeholders highlights the importance of collaboration in advancing eco-friendly solutions. Testing and certification by CPBR demonstrates that plant-based plastics can coexist with traditional recycling processes, paving the way for broader adoption of sustainable materials in global packaging markets.
In conclusion, Avantium’s CPBR-approved releaf plastic represents a major advancement in plant-based recyclable packaging. The material offers a renewable, high-performance alternative for PET bottles, ensuring environmental benefits without sacrificing functionality. With strong industry support and verified recyclability, releaf exemplifies how innovation, sustainability, and circular economy principles can come together to transform packaging for a greener future.
