Development of Baker's Yeast Metal Adsorbent
Development of Baker's Yeast Metal Adsorbent
We have developed a material with high heavy metal adsorption capacity and selective adsorption of rare earth metals by phosphorylating baker's yeast using food additives. In addition, by cationizing bread yeast, we have developed a material that can adsorb toxic metal oxides such as selenite and has sludge flocculation ability.

Development of Low-Environmental-Impact Materials that Lead to Solutions to Environmental and Resource Problems
We will contribute to the stable supply of precious metals and rare earths essential for precision instruments, the removal of toxic heavy metals from factory wastewater, and the return of organic sludge generated in wastewater treatment to green agricultural land through the development of materials for metal adsorbents and flocculants using yeast as the main raw material.

ORIGINALITYUniqueness, Passion for Development
High-Performance, Biodegradable, Low-Environmental-Impact Material with Yeast as Its Main Raw Material
The main raw material, yeast, can be secured inexpensively from distribution and is a spherical material with hard cell walls that can be easily separated from solution. It has excellent material properties such as low environmental impact, biodegradable, and safe due to its food experience. There is no precedent for a metal adsorption material with a very simple chemical modification of yeast.
VISIONDream, Outlook, Business Image
Promoting Social Contribution Projects Through Wastewater Treatment and Resource Recovery
We are eager to contribute to society based on the results of our research over many years and aim to put them to practical use. Businesses will be launched in the order of the degree of technical difficulty, starting with the flocculants, wastewater treatment materials, and rare earth recovery materials. We will provide technical support to incorporate the materials into the wastewater treatment process and ensure a stable supply of materials.
