Japan is addressing the sustainability of hygiene products through innovative waste-reduction programs. Efforts are centered on eco-friendly procedures and reusing materials to reduce environmental effects, reflecting the country's rising emphasis on sustainable growth in the hygiene and geriatric care sectors. For instance, in January 2025, a public-private partnership in Japan, involving Unicharm and Poppy Paper, manufactured the world's first toilet paper made from recycled adult diapers. This campaign, which began in Kagoshima and Miyazaki, utilizes around 98 Metric Tons of hygiene waste while highlighting sustainability initiatives in Japan.

Moreover, collaborations in Japan's adult care industry focus on sustainable advancements, such as the development of biodegradable and high-absorbency diapers made from advanced bio-based materials. These initiatives seek to improve eco-friendly alternatives for senior care while also addressing environmental concerns and future market demands. For example, in June 2024, Nagase ChemteX Corporation, its parent business Nagase & Co., Ltd., and LiveDo Corporation signed an agreement to jointly develop adult disposable diapers and incontinence products. This joint development seeks to commercialize a product in 2027 or later that uses a polymer developed by the NAGASE Group with a high biomass content, biodegradability, and high absorbability (SAP) as the absorbent material in disposable diapers manufactured by LiveDo Corporation. Furthermore, the Japan adult diaper market is quickly developing to meet the growing demands of its elderly population. Manufacturers are focused on innovation, developing products with superior absorbency, odor control, and comfort to improve the user experience. Additionally, the industry's push toward eco-friendly and biodegradable products demonstrates its dedication to sustainability. For example, companies like Unicharm and Lion Corporation are investing in cutting-edge technology to produce ultra-thin and discreet diapers for active seniors. These initiatives not only address domestic needs but also appeal to foreign markets, notably in Europe and Asia, where aging populations are prevalent. The industry's concentration on eco-friendly techniques assures minimum environmental effect, which aligns with worldwide trends. Japan's adult diaper manufacturers are setting a high standard for geriatric care goods by integrating functionality, quality, and sustainability, meeting both present and future expectations.
