EcoTopia Science Institute Projects(since 2013)

The EcoTopia Science Institute has been defining its mission and formulating concrete action plans since its founding. Since 2007, we have been publicly soliciting open research projects. We intend to pursue a wide variety of interdisciplinary research covering diverse fields of environmental materials and energy systems by looking ahead to 2020–2030.

In FY2011, we conducted an interdisciplinary project concerning the building of a sustainable society and a sustainable technology system. Since FY2012, we have been earnestly discussing the reorganization of our projects. In FY2013, we summarized our research achievements using EcoTopia assessment indicators and published them as the EcoTopia Science Series. In addition, each research group that conducted interdisciplinary projects on environmental science eagerly published their results and details of their activities both in Japan and around the world.

In FY2014, the reorganization was completed. We initiated nine new projects to focus our efforts on the research and development of improved environmental materials and energy systems. To realize a sustainable society, we plan to concentrate our manpower and funds to research environmentally friendly materials and systems. In so doing, we aim to move towards the development of new materials and systems for the future.

Since the 2011 Great East Japan Earthquake and Tsunami, new energy-production systems and environmental issues have attracted much attention in Japan. Hence, we are keen to help establish a sustainable society by realizing our mission of “Green Innovation” through interdisciplinary projects.

Materials Production Project Cluster
Minor Metal Cycles and Resource Management Project
ICHINO, Ryoichi
MUTO, Shunsuke

To build a safe and prosperous circulation-type society, natural resources and the proper disposal of used products must be secured. For resource circulation, it is important not only to develop alternatives to hazardous substances, but also to develop high-precision measurement and evaluation technologies for raw materials. Thus, we strive to develop a resource strategy based on fundamental science to 1) reduce the consumed quantity of minor metals, 2) search for alternatives to minor metals and toxic materials, and 3) separate and recover minor metals from disposed products. We conduct basic and applied research on diverse topics related to these goals.

In this project, we invite researchers from diverse fields, including chemistry, physics, metrology, materials science, environmentology, and policy studies, to conduct research to evaluate and develop alternatives to minor metals and toxic elements, novel functions of such substances, and measurement technologies necessary to realize a circulation-type society. Additionally, we study social systems related to resource circulation to eventually develop and apply effective resource circulation technologies.

  • Principles of emerging environmental functions via nano-structure analysis of functional substances and materials
Energy Networks Project Cluster
Ecological Energy Conversion and Storage Project
NARUSE, Ichiro
NAKAMURA, Mitsuhiro

To concretely form a sustainable society, it is essential to develop ecological and highly efficient energy conversion of underutilized resources (e.g., fossil energy resources and biomass) and storage technologies for various kinds of energy. This project works to develop diverse and new elemental technologies, processes, and systems to meet all demands ranging from a large-scale centralized to a small-scale decentralized applications. To realize large-scale technologies, processes, and systems, this research team has proposed an optimal system that combines global environment-friendly energy conversion technologies for coal, which is plentiful and relatively well distributed, with fuel cells and other technologies. On the other hand, this research team sees various kinds of biomass and waste as underutilized local energy resources for small-scale applications, and aims to conduct basic research and development of elemental technologies to create locally produced and consumed types of co-generation systems, which can supply electricity or heat to the local community. Additionally, this research team is concurrently developing technologies to store various kinds of energy, which will ensure flexibility of the developed systems.

Intelligent Energy Network Project
KATO, Takeyoshi

To build and effectively use an energy infrastructure, which is the basis of a sustainable society, it is essential to create a series of energy networks related to the generation, transmission, conversion, control, storage, and consumption of energy. This project conducts research to resolve technical issues related to creating highly efficient, functional, and reliable energy networks with low environmental impacts. Hence, this research team investigates, discusses, and studies the creation of safe and secure cities and communities. Specifically, research focuses on:

  • Harmonious integration of conventional commercial power systems with those using clean energy (e.g., solar, wind, geothermal, biomass, and other underutilized energies)
  • Demonstration of micro power generation systems using a new type of small hydraulic turbine
  • Establishment of an emergency power supply through community disaster prevention networks that utilize autonomic decentralized power generation systems
  • Monitoring, diagnosis, and control of electric power and energy equipment that utilize information technologies
  • Development of innovative electric power equipment and systems that utilize superconductive materials

Environmental Conservation and Biotechnology Project Cluster
Environmental Biological Remediation and Conservation Project
HAYASHI, Kiichiro

To establish a sustainable human society, it is essential to maintain a quality environment (air, water, and land) and to control healthy ecosystem services based on maintenance of the environment. To this end, we conduct research on biological and physicochemical technologies to analyze and detoxify substances of concern. Additionally, we are undertaking research to comprehensively evaluate large-scale biodiversity, the ecosystem-service supply and demand status, and related environmental policies. In particular, our research focuses on 1) designing, activating, and applying microorganisms capable of remediating and restoring water and land polluted with chemical substances, 2) developing purification materials that capture and enzymatically decompose environmental pollutants, and 3) establishing recycling and/or energy-recovering technologies for discharged unused-biomass. Furthermore, we are evaluating the environmental effects of maintaining, managing, and restoring urban and rural areas and mountain forests (planted forests) in which our environmental biotechnologies have been applied using evaluation methods, such as life cycle assessment (LCA), resource occupancy indicator and ecosystem service assessment from the perspectives of water, food, and resource utilization.

Utilization of Biomass for Low-Carbon Society Project
NARUSE, Ichiro

Biomass is a renewable, sustainable, and carbon neutral energy source. Carbon neutrality means that biomass causes no increase in environmental CO2 levels when it is burnt. In this project, we are utilizing biomass to generate energy effectively and economically by setting the establishment of a low-carbon society as a long-term goal. In particular, we are working on the development and practical applications of methane fermentation technology, high temperature gasification technology, gas cleaning and upgrading technology, and storage technology for methane and hydrogen. We will depend on both national projects and collaborations with private companies to achieve our long-term goal. A specific example is a high-efficiency methane fermentation technology we are developing that utilizes a fixed-bed technique that fixes methanogenic bacteria to carriers. We are also aiming to improve storage capacity of adsorbents under low-pressure conditions at room temperature by developing new materials for adsorbents. In addition, we are working in close collaboration with both governments and private industry to develop and disseminate waste and wastewater treatment technologies. These technologies will be used in disaster areas and in developing countries, including Thailand, Bangladesh, and Egypt.

Radioactive Materials Recovery and Restoration Project
NAKAMURA, Mitsuhiro

Because modern society frequently uses radioactive materials, technology to monitor and control these materials, especially those with long half-lives, is indispensable. This project will develop nuclear emulsion technology for muon-radiography with an emphasis on investigating the inner status of the Fukushima Daiichi power plants.
