Cost reduction of microalgae culture for fuel in Mie



It was a dream from a high school student,
Helping people with the power of bio

-I want to help people with the power of biotechnology.
Since high school, Takeda had a dream of "changing the world with the power of photosynthesis."

In October 2015, when I returned to Japan with Hideyuki Suzuki from research on euglena culture for biofuels in the United States, Arata, who was the manager of the Biofuel Development Division, called out.

"In anticipation of producing microalgae such as Euglena as a raw material for commercial biofuels, please establish a method that enables stable mass cultivation at low cost ...!"

This is how Takeda's next challenge, which has been focused on outdoor mass culture and research of Euglena since joining the company, began.

The world's first attempt, applying Japanese frost coating technology
Cost reduction of Euglena production by construction of culture pool

In April 2016, Takeda ran all over Japan in search of a business operator who would cooperate in the outdoor cultivation of Euglena for biofuels. Then, three months later, the Chubu Plant Service, which owns a woody biomass power plant in Taki Town, Mie Prefecture, finally came up with the idea, "I definitely want to take on the challenge together!"

And September 2016.
Euglena Co., Ltd. uses exhaust gas, wastewater, exhaust heat, etc. emitted from woody biomass power plants as carbon dioxide sources and energy required for cultivating microalgaes with the cooperation of Chubu Plant Service, Mie Prefecture, and Taki Town. Announced that a fuel microalgae culture pool will be built adjacent to the woody biomass power plant.

After that, Takeda worked with the cooperation of many people, from the design of the construction to the management of the construction and the selection of equipment for the introduction of the culture equipment.

However, the challenge of cost reduction is not over yet.
"How can we cultivate at a lower cost ...
That's it! How about changing the way the culture pool is designed? "

The conventional microalgae culture pool is made of concrete, which is expensive and has a long construction period. As we proceeded with the introduction of culture equipment, we thought about changing the culture equipment itself, which is the basis of culture in the first place.

Therefore, Takeda focused on the agricultural technology possessed by Kobashi Industries, an agricultural machinery manufacturer in Okayama Prefecture, which has a history of more than 100 years, especially paddy field development technology. Originally, Kobashi Industries received a proposal that "paddy field development technology could be used for culturing microalgae," and in 2014, we concluded a joint research agreement on an efficient and stable culturing method for microalgae. , I was doing research.

And finally July 31, 2017.
Euglena, Inc. announced that it will start the construction and operation of the ridge-type microalgae culture pool, the world's first an application of the ridge coating technology of paddy field reclamation of Kobashikogyo.
* Aze ... A partition between rice fields that has been raised and hardened with soil.

As a result of actually constructing a large pool of 1,000 square meters, Takeda et al.'S research shows that the construction cost is about one-tenth that of a culture pool constructed of concrete because the soil is solidified in a ridge shape. In addition, the construction period has been reduced to about one-fourth, and it has become clear that it will be possible to reduce the production cost of microalgae for fuel, which is required in large quantities, and to quickly respond to the expansion of production volume.

The scale of the ridge-type microalgae culture pool is scheduled to be expanded by the end of 2018 in line with the expansion of the culture scale.
Through trial and error every day, Takeda is steadily progressing step by step toward the realization of his dream of "changing the world with the power of photosynthesis" since he was a high school student.

Biofuel Development Division Team Leader
Seiya Takeda

Joined the company in April 2012.
Since joining the company, he has belonged to the Biofuel Development Division and is in charge of outdoor culture for biofuel development in Ishigaki Island and the United States. Since 2016, has been engaged in biofuel research using exhaust gas and exhaust heat from power plants.

"I'm still in the middle of my dream, but I feel that I'm making steady progress step by step. I would like to continue my research with many colleagues in order to realize a future in which airplanes fly in Euglena in one day."
