In this study, an attempt was made to synthesize hydrogrossular, a group of garnet minerals, under hydrothermal conditions
at temperatures below 180°C, using coal ash, which is the solid waste from thermal power plants, as a starting material. A
single phase corresponding to hydrogrossular was found at around 120°C, and the hydrogrossular coexisted with 11-Å tobermorite
above 140°C. The hydrogrossular phase decreased with increasing reaction temperature, while that of 11-Å tobermorite increased
concurrently. The physicochemical properties of the hydrogrossular obtained from the hydrothermal synthesis was characterized
by X-ray diffraction thermogravimetry/differential thermal, analysis, scanning electron microscopy, Fourier transform infrared
spectroscopy, and X-ray fluorescence spectroscopy.

This paper introduces the recent appearance of a circular economy in such industrialized countries as Germany and Japan and outlines its concept and principles. The author emphasizes that a circular economy should become the breakthrough point for sustainable development and will enable a shift to a sustainable society of "doing less with less" away from the current high-consumption society of "doing more with more" 相似文献

This paper describes a case study of the application of life-cycle inventory analysis to automotive bumper recycling. Two
scenarios of bumper recycling are compared. One is “bumper-to-bumper recycling,” in which we recycle bumpers into more bumpers.
The other is “cascade recycling,” in which bumpers are recycled into different parts of a car with a lower function. Inventory
analysis is applied to both these recycling scenarios by analyzing the stages of acquiring natural resources, manufacturing
materials, and parts, disposal, and recycling. We chose air emission, solid waste, and fossil fuel resources as items of the
inventory analysis. We quantified the effect of reductions in the environmental load by recycling bumpers, and found that
reductions in the environmental load were larger with cascade recycling than with bumper-to-bumper recycling based on current
conditions.
