ITOCHU Announces Launch of Pilot Project for Cellulose Nanofiber-Reinforced Plastic Logistics Materials

-

ITOCHU Corporation today announced the launch of a joint demonstration project for cellulose nanofiber (CNF) reinforced plastic logistics containers in collaboration with FamilyMart Co., Ltd. SANKO Co., Ltd. , and the Research Institute for Sustainable Humanosphere, Kyoto University (headquartered in Uji, Kyoto; Mamoru Yamamoto, Director; hereinafter “Kyoto University”). The pilot demonstration project has already been selected for the FY2025 Cellulose-based Circular Economy Business Demonstration Project by Shizuoka Prefecture. This initiative will run for approximately six months from August 2025 at about 80 FamilyMart stores in Shizuoka to verify the performance of CNF-reinforced plastic containers.

CNF is produced from sustainably sourced wood and imparts high-performance characteristics such as strength and recyclability. Although the global CNF market size was estimated at only 6 billion yen in 2024, it is expected to see significant growth as a sustainable biomass-based alternative to replace fossil-based materials for decarbonization. Research institutes such as universities and companies in Japan have played a pioneering role in CNF research and development. However, commercial applications of CNF remain limited due to high cost and other challenges. The project aims to move forward the transition of the advanced material from R&D stage to commercial-scale industrial use.


ITOCHU has recently begun developing CNF-reinforced plastic logistics materials in collaboration with Sanko, the largest plastic logistics material manufacturer in Japan. CNF provides a sustainable solution by enabling the production of thinner, lighter and stronger plastic logistics containers. In response to current logistic challenges, FamilyMart, the second largest convenience store chain in Japan, decided to join the demonstration project prioritizing workload reduction and loading efficiency improvements. This initiative will mark the world's first implementation of CNF-reinforced plastic materials in a retail store setting.


The product developed in this project is a logistics material known as a shallow container (commonly known as a bat) for food transportation. Sanko will produce CNF-reinforced plastic shallow containers. FamilyMart will use them for chilled food transportation to about 80 stores in Shizuoka. In addition, Specially Appointed Professor Hiroyuki Yano, Kyoto University, one of the world-renowned authorities on CNF, will support its product performance assessment, environmental assessment and product engineering. The consortium will aim to achieve a reduction in thickness and weight of more than 15% and to explore other logistics applications.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
