GRACE signed a joint research agreement with Yokohama National University Promoting joint research to develop new products using cellulose nanofibers derived from coffee grounds and other food waste
GRACE Co., Ltd. (Headquarters: Nishi-ku, Yokohama City, Kanagawa Prefecture, Representative Director: Yuta Sawamura, hereinafter GRACE) signed a joint research agreement with Yokohama National University on November 1, 2022. Agreed with the research group of Associate Professor Izuru Kawamura of the Graduate School of Engineering (Kawamura Lab) to develop new products using cellulose nanofibers (CNF) derived from coffee grounds and other food waste. did. Background of the conclusion of the joint research agreement In April 2020, we succeeded in generating CNF in research on applying the TEMPO oxidation method* to spent coffee grounds (SCGs), which Kawamura Lab has been working on since around 2018. GRACE paid attention to the results of this research, and by providing coffee grounds generated by the company’s cafe business “UNI COFFEE ROASTERY” and supporting research, we will improve the accuracy of this research and use them. We will continue to develop new products.
In addition to coffee grounds, we will continue to deepen our collaboration with Yokohama National University and Kawamura Lab. -TEMPO oxidation method-
TEMPO is 2,2,6,6 tetramethylpiperidi-1-oxyl, an organic nitr radical that is stable at normal temperature and pressure.
Cellulose nanofibers can be produced by reacting natural cellulose in an aqueous solution containing a catalytic amount of TEMPO and performing a slight fibrillation treatment. In 2006, a research team led by Professor Akira Isogai of the University of Tokyo discovered that a carboxylation reaction was occurring on the surface of crystalline cellulose microfibrils, and that this technology could be used to nanosize cellulose by electrostatic repulsion. reported.
