Osaka, Japan, January 7, 2025 – Panasonic Holdings Corporation (Panasonic HD) has developed a molding material with full marine biodegradability by applying the technology the company has been developing to incorporate highly concentrated cellulose fiber derived from plants into resins. By adding plant-derived cellulose fiber at high concentrations to marine biodegradable resins, Panasonic HD has succeeded in developing a molding material that achieves both excellent mechanical properties and marine biodegradability.

kinari is a sustainable material that uses highly concentrated natural raw materials and reduces the use of petroleum by 55-70%.
We are continuing to challenge biodegradation, which means that even after the product is no longer used, it breaks down into water and carbon dioxide.

We're also working hard to improve our kinari material to achieve 100% plant-based content with no compromises on performance, while developing a more efficient recycling process in order to realise a completely closed circular material system.

kinari is one of Panasonic’s key bioplastic solutions in response to rising plastic-related environmental issues globally. Kinari is a high performance, plant-based plastic materials containing up to 85% cellulose; yet it has almost the same properties as petroleum-based resins. This video introduces key features of kinari, examples of kinari-based product development in collaborations with Japanese and global companies, and Panasonic’ approaches to realize circular-economy based society under the Group’s long-term environmental vision called Panasonic Green Impact (PGI). 

In April 2023, Panasonic Production Engineering Co., Ltd. will start selling samples of kinari * 1 (Below, omitted as kinari70), a molding compound made from 70% plant-derived cellulose fiber and resin, developed by the Manufacturing Innovation Division of Panasonic Holdings Corporation.

In December 2022, Panasonic Production Engineering Co., Ltd. began mass production sales of kinari (* 1), a molding material developed by the Manufacturing Innovation Division of Panasonic Holdings Corporation, which is made from 55% plant-based cellulose fiber compounded with resin, as well as handling trial materials on an online shopping site operated by Chip One Stop Co., Ltd.

The Manufacturing Innovation Division of Panasonic Holdings Corporation, has developed a fully biodegradable molding material (2) by applying its previously developed technology for blending a high concentration of plant-derived cellulose fiber into resins to biodegradable plant-derived resins (polylactic acid) and other materials. By adding a high concentration of cellulose fiber to biodegradable resin, we succeeded in developing a molding material with excellent mechanical properties and biodegradability.

Fukuchiyama City, the Manufacturing Innovation Division of Panasonic Holdings Corporation and Panasonic Production Engineering Corporation (hereafter referred to as the Panasonic Group) have agreed and signed a collaboration agreement to promote SDGs initiatives and build a circular society through the development of school lunch tableware for 23 Fukuchiyama municipal elementary and junior high schools.

Panasonic Production Engineering Co., Ltd. has jointly developed the washroom and bathroom goods "Soap dispenser: Albero" and "Soap dish" with K-World-ism Co. (Headquarter : Osaka, Company President : Kenji Sawai), utilising "kinari"*1, a moulding material in which plant-derived cellulose fibres are mixed into the resin at a high concentration of 55%. The products will be launched by the K-World-ism Lindpark division in early May.
