Outline

This research aims to establish a novel material creation and efficient metal recycling process based on “precision dissolution control,” which selectively and efficiently dissolves targeted critical metals from waste. Focusing on ionic liquids and deep eutectic solvents, which are environmentally friendly solvents with molecular design potential that can replace ordinally water and organic solvents, the study aims to develop the scientific principles of precision dissolution, enabling highly accurate separation of critical metals with similar properties. Furthermore, the research will challenge upcycling by utilizing the critical metal solutions obtained through precision dissolution as synthesis and reaction media.

Outline

A copolymer, developed for the first time in Japan, was found to toughen the polyolefin interface. This result provides the basis for recycling polyolefins as a mixture and allowing them to be reused multiple times without separating them into single spices. Our study is a collaborative effort to reveal the copolymer’s interface toughening mechanism. We are utilizing advanced polymerization techniques, cutting-edge electron microscope measurements, and interface structure analysis using computational science integrated with microscope measurements to build a circulation society for polyolefins.

This project aims to identify the properties of steel scrap and the mechanism of microstructure formation in steel containing unforeseen impurity concentrations using also data-driven metallurgical models, resulting in creating a scientific discipline to design a material production chain that controls variation by integrating industrial ecology and materials science based on the concept of Recovery-Processing-Structure-Properties-Performance. In line with R-PSPP, we will develop chemical composition estimation by image analysis, high-temperature oxidation as surface metallurgy, low-temperature hot rolling techniques, and new standard test methods for fracture resistance properties.

Outline

This research aims to create “multinary carbon” from untapped organic matter such as waste plastics, biomass, and greenhouse gases, functioning as adsorbents, electrodes, and catalysts. The goal is to establish domestic carbon resources and carbon cycling technologies. By overcoming challenges in controlling the structure of complex organic materials, innovative methods like low- and high-temperature carbonization, as well as catalytic carbonization, are employed to produce porous and conductive carbon materials. Advanced structural analysis, such as synchrotron radiation, will be utilized to clarify formation mechanisms and material properties. This study explores groundbreaking possibilities for carbon materials, aiming for a game-changing approach to carbon recycling.
