Unicharm Corporation announced the development of an innovative “dry cleaning method” as a key component of its “RefF (Recycle for Future)” disposable diaper recycling initiative. This pioneering technology is expected to pioneer new pathways for global disposable diaper recycling, particularly in water-scarce regions.
The core breakthrough lies in drastically reducing water consumption. Compared to conventional methods, the dry cleaning process reduces water usage during washing to approximately 1/50th.
Traditional diaper recycling required significant water resources, posing a major obstacle in regions with weak or scarce water infrastructure. By applying the core principles of dry cleaning—using recyclable solvents combined with unique sterilizing bleaching technology—the method achieves hygienic processing while substantially conserving water. This makes it possible to transform “used diapers” into “new resources” globally.
The RefF project, dedicated to horizontal recycling, began in 2010. In 2019, Unicharm achieved a world first by successfully producing “regenerated pulp” comparable in quality to unused products using ozone treatment technology. The company has also established a technical system for recycling plastics and superabsorbent polymers in commercial products.
Unicharm has established a clear technical deployment timeline:
2026: Initiate R&D
2028: Begin construction of full-scale recycling plant
2029: Plant commences operations and launches comprehensive recycling in collaboration with local municipalities
Following successful implementation in Japan, Unicharm plans to expand into overseas markets, demonstrating leadership in addressing global environmental challenges.
