Gallium is used as a raw material for a CIGS solar cell. In the manufacturing process of CIGS solar cells, only 30% of the target material is used, and the rest is not used and becomes a spent target scrap. In order to recover gallium from spent target scrap, we investigated the process composed of hydrometallurgical treatment only which does not require pyrometallurgical treatment. We describe the details of the developed process in this report.

Coal Mine has researched and studied for the development of gas collection technique and effective utilization system. As part of the investigation, Kushiro Coal Mine and Osaka Gas have promoted the effective utilization by gas concentration technique using Pressure Swing Adsorption, and the whole system has operated in 2017. The purpose of this article is to review general design of the gas concentration project of Kushiro Coal Mine.

limited around a well. In order to develop co-axial UCG system with high efficiency, the model UCG experiment with a large-scale simulated coal seam were conducted. It has been shown that 1) the gasification period can be extended by adopting proper oxygen inflow, 2) it is possible to control the combustion/gasification area and the product gas quality by controlling the position of oxygen inflow, 3) acoustic emission monitoring is an effective technique to evaluate the combustion/gasification area.
