How Unicharm’s Ultra‑Low‑Water Diaper Recycling Breakthrough At Unicharm (TSE:8113) Has Changed Its Investment Story

Simply Wall St · 1d ago
  • In December 2025, Unicharm announced it had developed a “Dry Washing Method” for its RefF disposable diaper recycling project, cutting water use in the washing process to about one-fiftieth of its previous in-house methods by using reusable solvents plus proprietary sterilization and bleaching technologies.
  • This advance could help turn used disposable diapers into reusable resources even in regions with limited water infrastructure, broadening the potential reach of diaper recycling worldwide.
  • Next, we’ll look at how this water-saving Dry Washing Method could influence Unicharm’s investment narrative and long-term competitive positioning.

What Is Unicharm's Investment Narrative?

To own Unicharm, you need to believe its core hygiene brands can convert modest, steady growth and high‑quality earnings into attractive long‑term compounding, even after a tough share price stretch and slower forecast growth than the broader Japanese market. Recent guidance cuts for 2025, softer profit margins and a relatively full P/E versus peers keep near‑term execution and input‑cost management in focus, while a lower dividend payout shifts more emphasis onto buybacks and internal reinvestment. Against that backdrop, the new Dry Washing Method looks more like a long‑term optionality play than a near‑term catalyst, but it does strengthen Unicharm’s sustainability story and could, over time, reinforce its competitive positioning in emerging markets. For now, the immediate drivers remain earnings delivery, cost discipline and capital allocation.

Unicharm's shares have been on the rise but are still potentially undervalued by 42%. Find out what it's worth.
