Circular Materials Creation Lab
Machine-translated · View original
A lab that creates new eco-friendly wood-based materials from wood and plants.

AboutAbout the lab
New eco-friendly materials made from woody biomass.
The Circular Materials Creation Lab creates new wood-based materials with a low environmental impact by making use of the structure and functions of woody biomass, and also conducts research to deeply understand and evaluate the characteristics of those materials.
The lab studies not only wood but also unused biomass such as herbaceous plants and agricultural waste.
Key terms
- Wood-based materials
- Materials made by breaking wood down into boards, small pieces, or fibers and bonding them back together
- Natural adhesives
- Adhesives made from biological resources rather than petroleum
ResearchResearch themes
The lab studies the creation of new low-environmental-impact wood-based materials that make use of the structure and functions of woody biomass, and the evaluation of those materials.
*Illustrative imageDevelopment of new wood-based materials
Aiming at effective and sustainable use of plant biomass, the lab develops eco-friendly wood-based materials with practical-level performance and productivity from unused biomass such as wood, herbaceous plants, and agricultural waste.
*Illustrative imageNew natural adhesives
The lab is developing natural adhesives that rival synthetic adhesives, which depend on fossil resources. It discovered, for the first time in the world, that a mixture of citric acid and sucrose can be used as an adhesive.
*Illustrative imageAging of wood and wood-based materials
Through analysis of materials that have actually aged and a unified analysis of natural aging and accelerated degradation, the lab aims to clarify the mechanisms of aging, predict service life, and create materials that reproduce the effects of aging.
*Illustrative imageDeveloping wood-based materials with artificial intelligence
With the help of artificial intelligence, the lab aims to develop systems that evaluate the properties of wood-based materials quickly and with high accuracy, optimize manufacturing conditions, and explore new wood-based materials.
