By establishing an outdoor mass cultivation technology for microalgae, we will be the first in the world to enable a stable supply of microalgae oil (algae oil) as a raw material for biojet fuel, and we will also provide a feed material that replaces fish flour, which is a depleted marine resource. We aim to realize a sustainable business that contributes to the protection of marine resources by supplying a large amount. Integrated production process development from research and development of high-efficiency and low-cost culture method using CO 2 emitted from the adjacent woody biomass power plant and waste heat to harvesting, drying and algae oil extraction, value of algae oil extraction residue・ Through culture research that contributes to quality improvement, we are conducting a comprehensive business feasibility evaluation of the fuel and feed business.

Message from the director

In order to realize a society of net zero carbon in 2050, the contribution of CO 2 emission reduction in the transportation industry including the aviation industry is very large, and in particular, the biotechnology of fuel is an unavoidable issue. Our strength lies not only in collecting waste-based fats and oils such as waste cooking oil as a biofuel raw material portfolio, but also in producing and supplying our own biomass raw materials with our own technological capabilities. However, in order to resolve global issues at an early stage, it is essential to strengthen cooperation with universities and companies with various strengths. From basic research in our own laboratory, we will comprehensively promote the strengthening and scale expansion of the research system through open innovation in Japan and overseas, and will continue to make daily efforts toward the realization of a sustainable society pioneered by biotechnology. increase.

Research case introduction


1000m3 Aze-type microalgae culture pool

At the Algal Energy Technology Research Institute, with the cooperation of the adjacent Taki Biopower Woody Biomass Power Plant, low-cost production of microalga Euglena using high-concentration CO 2 contained in the exhaust gas of the power plant and high-temperature waste heat of the exhaust gas. You have successfully developed the process.

Research content

Since the microalgae Euglena can grow even when exposed to high-concentration CO 2, it is possible to significantly increase productivity by supplying a gas containing high-concentration CO 2 to the culture pool, such as power plant exhaust gas. I can do it. Although the exhaust gas meets the emission standards of the Air Pollution Control Act, it also contains impurities such as soot dust, Sox, and Nox, but Euglena suffers from growth inhibition even when compared to the case where pure CO 2 gas is aerated. It has been demonstrated that it can grow equally without any. In addition, since exhaust gas is emitted at a high temperature of about 120 ° C, we have also developed a method to utilize this heat for drying Euglena after harvesting.
In this way, by utilizing waste heat energy, the amount of energy invested in production can be suppressed, and the effect of reducing the environmental load of Euglena-derived biofuel can be maximized.

Succeeded in developing Taki sustainable salmon

Taki Sustainable Salmon

The Algal Energy Technology Research Institute, in collaboration with Taki Town and Chubu Plant Service Co., Ltd., has developed a low fish flour "Taki brand feed" using unused resources from Taki Town and microalgae Euglena, as well as "Taki Sustainable Salmon". Was developed.

Research content

The Taki brand feed developed this time contains the microalgae Euglena produced by the Algal Energy Technology Research Institute as a protein source, which keeps the fish meal usage fee lower than that of general fish feed. In addition, Ise potato, sake lees, Matsusaka beef beef, rice bran, mikan, Jiro persimmon, Ise tea, etc., which were discarded as non-standard products and by-products in Taki Town, are blended as a source of lipids, vitamins, minerals, etc. .. In addition, the crayfish, which has been targeted for extermination due to concerns about its impact on the ecosystem, is also added for the purpose of feeding stimulation and color enhancement after being captured and powdered.
The Algal Energy Technology Research Institute was in charge of Euglena production and feed production, Taki Town was in charge of collecting unused resources, and Chubu Plant Service was in charge of breeding in a closed circulation aquaculture tank. Since the closed circulation type reuses the water in the aquarium, it has less impact on the environment and can be cultivated on land without restrictions on the installation location, so it is a culturing method that has been attracting attention in recent years.
