Worked at Canon Inc., and then joined AIST in April 2007. After joining AIST, engaged in development of immobilization technology for molecular catalysts and direct manufacturing technology of functional chemical products using sand as raw material. Specialties are organic metal chemistry and catalyst chemistry. In this paper, was in charge of the synthesis of silica with high specic surface area from molten slag as well as the general supervision of joint research.Discussions with Reviewers1 OverallComment (Naoto Kobayashi, Waseda University)This paper presents highly signicant research result from the perspectives of practical realization through collaboration with industry, as well as technological development and its application, aiming at the effective use of molten slag produced from garbage incineration plants. Also, the concept of conversion from “venous industry” to “arterial industry” is very attractive. On the other hand, the details of the elemental technologies and their mutual relationships were not clear in the rst draft, but this became clear in the nal draft, and now the whole story is easier to understand.Comment (Keiichi Ikegami, AIST)This paper describes the development of technology to generate high performance materials that are made from incineration residues that have negative value (requires disposal cost). These materials are valuable in arterial industry, rather than in venous industry. Unlike conventional PET recycling and precious metal recovery that involve sorting and obtaining products with high purity, the innovation here is that smart synthesis is carried out based on the chemical equilibrium theory. As the authors write, it is an excellent example that shows that “when research results progress to the next stage, collaboration with human resources with different specialties is important,” and therefore, this paper is appropriate for publication in Synthesiology.
