Promoting green innovation

To promote green innovation, AIST is developing technologies for increased use of alternative energy technologies, such as renewable energy sources that reduce greenhouse gas emissions (energy creation), high-density storage of energy (energy storage), highly efficient conversion and use of energy (energy saving), effective utilization of energy resources, and evaluation and reduction of environmental risks.

New Research Results

Treatment of Heavy Metal Containing Wastewater Using Microbes, Rice Husk, and Rice Bran

AIST and JOGMEC worked to identify microbes that are critical for the stable bioreactor performance and optimize the operating conditions. The results indicated that only one sulfate-reducing bacteria was exceptionally tolerant of relatively aerobic environments, and that maintaining the activity of this bacterium could be important for stable wastewater treatment. Since this system can remove heavy metals from the wastewater with low cost and low environmental impact, it will be also applied to industrial wastewater.

Development of High-speed Polishing Technology for Large Diameter SiC Wafers for Power Semiconductors

Researchers in AIST developed lapping technology that achieved high-speed planarization of SiC wafers in collaboration with Mizuho Co., Ltd. and Fujikoshi Machinery Corp. In particular, 12 times the polishing speed was achieved in the previously slow mirror finishing process. The new batch processing technology demonstrated the comparable surface quality to that of a mirror grinding process using the single wafer processing method.

Open Innovation Laboratory

Since FY 2016, as a part of the “Open Innovation Arena concept” promoted by the Ministry of Economy, Trade and Industry (METI), AIST has created the concept of “open innovation laboratories” (OILs), collaborative research bases located on university campuses, and has been engaged in their provision. We are planning to establish more than ten OILs by FY 2020.

AIST will merge the basic research carried out at universities, etc. with AISTʼs goal-oriented basic research and applied technology development, and will promote bridging research and evelopment and industry by the establishment of OILs.


Cooperative Research Laboratories

In order to conduct research and development more closely related to strategies of companies, we have established collaborative research laboratories, bearing partner company names.

Partner companies provide their researchers and funding, and AIST provides research resources, such as its researchers, research facilities, and intellectual property. The loaned researchers of companies and AIST researchers jointly conduct research and development.

By setting up cooperative research laboratories, we will accelerate the commercialization of our goal-oriented basic research and application research with partner companies.
