It was the movie “An Inconvenient Truth” by a former vice president of the United States, Al Gore, which raised my awareness about global environmental issues and seriously made me consider that we need to take an action. As I age and became a parent myself, I began to constantly think about how I could make meaningful use of “my time left” and what I could leave behind for my children.
As symbolised by the SDGs adopted at the UN Summit in 2015 and “Paris Agreement” at the UNFCCC Conference of the Parties (COP) which is responsible for discussing the international agreements on greenhouse gas mitigation, an international awareness of the significant and urgent issues on global environment is growing. However, there were many companies and organisations which did not take the necessary action, excusing themselves as calling such environmental actions as “propaganda,” which triggered me a profound sense of crisis.
However, as some big global companies have stareted to take painful and effective actions, even in the field of IT business venture which I am familiar with, people started to “take action”; a legendary venture capitalist, Mr. John Doerr, donated 150 billion yen to newly establish a sustainability-related department at Stanford University, being a green tech evangelist, and Mr. Bill Gates called for the establishment of a 130 billion yen fund named Breakthrough Energy.
As these “actions” stareted to give me a kick in the back, I came across the microalga, Galdieria sulphuraria.
Galdieria is a red alga which inhabits hot sulphur springs such as Kusatsu Onsen and has existed on the earth by a billion years ago. It survives in harsh environments such as high temperatures, high acidity, high concentrations of CO2 and in the presence of sulphur oxides (SOx) and nitrogen oxides (NOx). They grow autotrophically in the presence of light and grow heterotrophically with nutrients in the absence of light.
These characteristics enable industrial-level high cultivation efficiency as well as low-cost production.
Galdieria is able to selectively and throughly collect precious metals such as gold (Au) and palladium (Pd) from dilute metal solutions and adsorb on the cell surface, displaying higher performance than the existing technologies (ion exchange resins, activated charcoal, etc.).
n addition, the cell contents include a variety of nutrients and useful substances as is the case for the other microalgae, which can be applied as food, cosmetics, dyes and other products.
In other words, Galdieria has a potential to contribute and provide a holistic solution to globally significant issues such as improving the efficiency of precious metal recycling at urban mines, eliminating mercury damage at overseas gold mines, overcoming food problems and reducing CO2 emissions.
We will challenge every day for realisation of a harmonious future among people, nature and the earth by harnessing the power of a unique microalga the mother earth has given a birth to.
At the same time, we aim to create an attractive and unprecedented corporate entity where each and every one of us can develop and flourish with a sense of responsibility and professionalism in each field.
We are a deep tech venture with a mission of “establishing an optimal ecosystem for the earth and all living organisms,” which aims to achive a circulating society by harnessing the power of extremophilic algae.
We contribute positively to achive some of the 17 SDGs as stated below.
We believe our environment-concious precious metal adsorbent can contribute to sustainability providing solutions to a wide range of social issues.
Of all others, the working conditions at artisanal and small-scale gold mining (ASGM) in Asia and South America are next to health hazards.
People without proper knowledge on mercury including child laborers work there, handling it with bare hands and evapourating it with burners.
The workers are forced to choose working at ASGM for their family lives and children’s education, knowing the potential health risks.
In addition, the areas that have been exhausted are deserted and new areas are mined, leaving serious soil contamination with mercury behind which is causing significant environmental damage in the surroundings.
The cyanide process, a so-called legitimate method, requires a high initial investment cost and cannot be adopted at ASGM compelling the workers to live with a negative cycle of poverty and environmental poisoning.
Along with the development of precious metal adsorbent derived from Galdieria, we have succeeded in developing a gold recovery process from ores that can be applied to ASGM.
This new gold recovery process allows the ASGM operators to safely extract gold from ore without using mercury.
Using our technology, we aim to eliminate the cycle of environmental pollution which poses negative effects in the future by contributing to sustainability of the people involved in ASGM in Southeast Asia, Africa, and South America.
After starting his professional career at Booz Allen Hamilton, where he worked for five years, Mr. Tanimoto moved to Silicon Valley and conducted international business expansion services to startups for six years. In year 2000, he moved back to Tokyo and founded Realcom, Inc., an enterprise software company and did IPO in 2007 at the Tokyo Stock Exchange. After leaving Realcom, Mr. Tanimoto founded TENEX, Co. and assisted entrepreneurs as an angel investor and a mentor.
In 2015, he co-founded Galdeira, Co., Ltd and now he leads the company as CEO.
He received an MBA from Keio Business School in Tokyo and completed exchange student program at the Wharton School, University of Pennsylvania. He also completed executive program at The Lee Kuan Yew School of Public Policy.
Member of MENSA Japan and summited Denali in 2014.
In a leading aerial surveying company, he handled the proposal and implementation of systems known as GIS, which are based on maps for analysis and information sharing. He expanded the use of maps as a data perspective into various industries, including systems for urban planning and water and sewage management for national and local governments, as well as marketing systems for private companies.
Leveraging this experience, he transitioned into the IT industry, focusing on information sharing within companies. At Realcom Inc., founded by Tanimoto, he gained experience in project management for large projects that connected the headquarters and agencies in the insurance industry.
Subsequently, he was responsible for business development, launching the company’s own cloud service, and developing and selling new products. After experiencing the impact of technology on society in the IT industry, he believed that Gardieria, a product not bound by language, could achieve nonlinear growth even from Japan, and joined the company in 2019. In our company, in addition to managing multiple projects such as large-scale projects with NEDO and demonstration experiments with customers, he is balancing market requests and technical development by creating products and cultivation equipment together with researchers.
Eri graduated International Christian University as B.A. majoring in organic chemical synthesis. Eri then switched over to biology, moved to UK and obtained Ph.D. in plant science researching hormone interaction in Arabidopsis at University of East Anglia. She moved to Canada and worked on annual nitrogen circulation and defence response in conifers at University of Alberta as a postdoctoral fellow.
In 2011, Eri moved back to Japan and spent nine years as Postdoctoral Researcher and Research Scientist at the Environmental Response Research Unit, RIKEN Center for Sustainable Resource Science (former Plant Science Center). Her research in RIKEN focused on cesium uptake mechanism and phytoremediation in land plants and salt tolerance mechanism in Neopyropia(Rhodophyta).
In 2019, she joined Galdieria and is involved in dissection of metal adsorption mechanism, seeking market potential of cell content and so on.
