According to reports, Panasonic Holdings Corporation (Panasonic HD) has successfully developed a marine biodegradable molding material by integrating high-concentration cellulose fibers derived from plants into resin using its proprietary technology. This innovative material not only boasts excellent mechanical properties but also aligns with sustainability goals.
Globally, there is growing concern over plastic pollution, depletion of petroleum resources, and climate change. Reducing resin usage has become a vital step toward achieving the United Nations Sustainable Development Goals (SDGs), including the efficient use of natural resources and significant reduction of marine pollution. Panasonic HD has been actively addressing this need since 2015, focusing on alternatives to petroleum-based resins.
In 2019, Panasonic HD introduced a composite processing technology that incorporated cellulose fibers at a concentration of 55%, significantly enhancing material performance. By 2021, the fiber concentration was increased to 70%, and in 2022, the biomass content surpassed 90%. In December of the same year, the company developed fully biodegradable molding materials using plant-based resins such as polylactic acid (PLA), improving their biodegradability in natural environments. However, traditional biodegradable materials still faced challenges decomposing in marine environments.
To address this issue, Panasonic HD refined its mixing and molding processes to create a new type of cellulose-based molding material with 100% biomass content. This material is fully biodegradable in marine environments and matches the strength of polypropylene (PP), commonly used in durable applications. Moreover, the material retains the signature advantages of Panasonic's "kinari" materials, being available in white granules that can be colored as needed.
The new material has been certified by the Japan Bioplastics Association as "Marine Biodegradable and Biobased Plastics." At CES 2025 in Las Vegas, Panasonic HD showcased this groundbreaking material and announced plans to commercialize it by 2027. It is expected to be widely used in applications such as appliance housings, automotive components, consumer goods, and food containers, providing a practical solution to plastic pollution.
By launching this marine biodegradable material, Panasonic HD demonstrates its commitment to driving green transformation and partnering with society to achieve a more sustainable future.
