Research paper−124−Synthesiology - English edition Vol.11 No.3 pp.124–132 (Feb. 2017) AIST took on the challenges of finding solutions to topics such as “achievement of high efciency in garbage treatment by local governments (improvement of profitability)” and “further use of distributed energy facilities” as new research topics. When the project is organized into Fig. 1, one realizes that when research results progress to the next stage, collaboration with human resources with different specialties is important, and it can be seen that the key point is to transmit the significance of the research results in a comprehensive manner when building such collaborative relationships and to have the results be recognized widely throughout society in the process of “result dissemination.” Since the field of specialties were totally different among the specialists who had the knowledge of plant operation for waste disposal plants at Mitsui E&S, the researchers working on chemical reaction and molecular design at the Interdisciplinary Research Center for Catalytic Chemistry, AIST, and the researchers studying chemical engineering or surface chemistry at the Research Institute for Chemical Process Technology, AIST, there was no opportunity for these people to directly exchange opinions in usual activities such as at academic meetings or at paper presentations. As R&D specialties become more diversified, it is becoming difcult to scan other elds or even science and technology in general. Therefore, events such as the Techno Bridge Fair in which AIST’s technological potential is introduced to people of industry are important, so they can get an overview of the research conducted at AIST and to transmit the results widely and systemically. Looking back, it can be said that the breakthrough point of this research was the matchmaking 1 Introduction1.1 Outline of this researchThe authors developed technology to manufacture silica with high specic surface area using molten slag that is generated from incineration plants for municipal garbage, in association with Mitsui E&S Engineering, Co., Ltd. (hereinafter, Mitsui E&S; was called Mitsui Shipbuilding & Engineering Co., Ltd. at the time this research was started; the company name was changed in April 2018). Silica with high specic surface area obtained using the jointly developed technology allows molten slag produced in venous industries (municipal garbage incineration plants) to be utilized as functional materials for arterial industries (chemical and materials industries). In this paper, we report the background for this development, the outline of the technology to advance the use of molten slag, and the future prospects.1.2 Scenario of this researchFigure 1 shows the overall scenario for matching technological potential (the seeds) and industrial demands (the needs) based on social issues that spurred this research, the road to discovery of technology, and the future prospects. The technological development for manufacturing functional materials from molten slag was conducted by the National Institute of Advanced Industrial Science and Technology (hereinafter, AIST) that was tackling the social issue “Achievement of energy savings in silica chemical products manufacturing” in the project of the New Energy and Industrial Technology Development Organization (NEDO). —Production of silica with high specic surface area from “molten slag” and direct transformation of silica to basic raw material for silicon chemical industry—We developed a technology for producing silica with high specic surface area from molten slag discharged by a garbage disposal plant. The obtained silica has purity and specic surface area comparable to commercially available synthetic silica. Therefore, this silica can be used in various applications, such as in adsorbents, rubber additives, and coating agents. Previous use of silica recycled from molten slag was limited to aggregate for concrete or asphalt. This research result means that silica recycled from molten slag can now be used as a functional material. We also report on “direct synthesis technology of functional chemicals using silica” as the starting point for this research, the research scenario, and future prospects.High-value materials from incineration residues of burnable garbage Keywords : Molten slag, silica, mesoporous silica, silicon[Translation from Synthesiology, Vol.11, No.3, p.128–136 (2018)]Norihisa FUKAYA1*, Sho KATAOKA2 and Jun-Chul CHOI11.Interdisciplinary Research Center for Catalytic Chemistry, AIST Tsukuba Central 5, 1-1-1 Higashi, Tsukuba 305-8565, Japan*E-mail:, 2.
