Eco-Products 2015: Report from Fujitsu's Booth

Eco-Products 2015, the largest environmental exhibition in Japan, was held at Tokyo Big Sight from December 10 to 12, 2015. The Fujitsu Group introduced ICT and the latest technology that supports various efforts to resolve environmental and social issues, such as natural disasters and the conservation of Blakiston's fish owls. Here is a report on Fujitsu's activities during the exhibition.

Fujitsu's theme this year was Environment x People x ICT

Introducing Fujitsu's solutions on stage using projection mapping in conjunction with ones on display

The theme of Eco-Products 2015 was "The Cool Future I Choose." About 700 companies and organizations presented their products and solutions with the latest environmental technologies and capabilities for resolving environmental issues and creating a sustainable society. A total of 169,000 people attended the three-day event.

The Fujitsu Group's theme this year was "Environment x People x ICT." The Group divided its exhibition booth into four sections; Natural Disaster Planning; Community Renovation; Conservation of Nature and Living Things; and Reducing CO2 Emissions to show its commitment to "always being a human-centric company that makes people happy" and what ICT can do to contribute to addressing global environmental and social issues. It also introduced Fujitsu's solutions that support people renovating communities and fighting natural disasters on stage with projection mapping.

ICT x People < Natural Disaster Planning > Section

The ICT x People < Natural Disaster Planning > Section introduced five systems and technologies for helping people quickly detect risks of social infrastructure and make decisions to prevent the spread of natural disasters.

Introducing solutions for different disasters using panels and videos

① Automatic Data Editing and Switching System (ADESS) and Automated Meteorological Data Acquisition System (AMeDAS) These systems make it possible to provide accurate information on torrential downpours.

② Technology for scheduling disaster recovery It formulates optimum work schedules for disaster recovery using a supercomputer.

③ Flood forecasting simulation technology The technology forecasts rainfall-induced changes in river flow rates. Using a distributed runoff model developed to study phenomena in which rainwater infiltrates soil and discharges into a river, the flood forecasting simulation instantly forecasts increases in river flow rates from the amount of rainfall into the river.

④ Technology for analyzing disaster information from social networking services
The technology analyzes tweets to detect the occurrence of a natural disaster. Hearsay elimination technique based on a probability model and machine learning removes unsubstantiated information and speculates the occurrence of a disaster. Then it displays its findings graphically on a map.

⑤ Technology for detecting early signs of sewer system overflows With the sensors installed on manholes, the technology quickly detects early signs of sewer system overflows caused by torrential downpours.

ICT x People < Community Renovation > Section

Location of available hydrogen stations can be checked in real time using a tablet

In the ICT x People < Community Renovation > Section, Fujitsu introduced Hydrogen Station Information Management Service, which uses location information service SPATIOWL, for contributing to community renovation.

SPATIOWL accumulates and analyzes data related to people, vehicles, facilities, etc., obtained from various sensors to produce new values. In the future there will likely be mobile hydrogen stations, and this Hydrogen Station Information Management Service provides real-time information on the locations and operational status of available mobile hydrogen stations using SPATIOWL.

In addition, Fujitsu Intelligent Society Solution Enetune-BEMS was presented. Enetune-BEMS was implemented in Date City, Fukushima Prefecture and successfully reduced energy consumption of its public facilities by more than 10%.

ICT x People < Reducing CO2 Emissions> Section

The ICT x People < Reducing CO2 Emissions> Section introduced Fujitsu's various technologies that exist around us which contribute to reducing CO2 emissions.

GaN-HEMT AC adaptor

For example, Fujitsu Laboratories announced on December 9, 2015 the world's smallest, most efficient 12W AC adapter, which enables super-fast charging of smartphones and other mobile electronics. Compared to other AC adapters with similar output, it is smaller than half the size and charges a battery in one-third the time, and consumes about half the power. The development of this new adapter was made possible by gallium nitride high electron mobility transistor (GaN-HEMT) (Note 1). Use of GaN-HEMT in the surrounding circuitry improved the conversion efficiency of electric energy, which had been a challenge. The new adapter successfully improved the power efficiency to 87% from the present 60-70%. About 2,100 million units of mobile devices are shipped worldwide today (Note 2). When regular AC adaptors are used, charging mobile devices would emit approximately 49 million tons of CO2 each year. If these regular AC adaptors are replaced by GaN-HEMT AC adaptors, we can reduce CO2 emissions by approximately 7.4 million tons (Note 3).

Widespread use of this GaN-HEMT AC adapter would contribute to reducing CO2 emissions.

The small silver cube on the round plate in the picture is the GaN-HEMT AC adapter. The smartphone on the right is being charged using this adapter (the part between the code and the power tap).

(Note 1) High electron mobility transistor (HEMT): A field-effect transistor that takes advantage of the operation of the electron layer at the boundary between different semiconductor materials that is relatively rapid compared to that within conventional semiconductors.

(Note 3) Calculated using CO2 emissions factor of 0.53.

Eco-friendly scoreboard Eco-Board

This baseball scoreboard is operated using only electricity generated from sunlight. The eco-friendly baseball scoreboard Eco-Board uses electricity generated by solar panels only when the displayed content is changed. Since it can display information in bright colors without other power sources, Eco-Board may be useful for displaying disaster-related information.

This booth introduced the activities of Fujitsu's own professional architects tackling the construction of power-saving data centers. One of the key points in data center construction is its power-saving design. In a data center, about 40% of the electricity is consumed by an air conditioning system to cool computers, such as servers. Therefore, they design data centers considering environmental contributions in terms of both ICT and architecture to reduce CO2 emissions from ICT, such as placing servers and computers all in one location.

Closed recycling system

From product to product - Fujitsu also displayed a closed loop material recycle system that conserves resources and the environment by recycling. Plastic housings of used personal computers collected at Fujitsu Recycle Centers are used to make chassis of mobile devices as recycled plastic. Compared with the production of such products without using recycled plastic, Fujitsu reduced CO2 emissions by 14% (in-house comparison).

Fujitsu Manufacturing Industry Solution PLEMIA EcoLink enables chemical substances used in products to be centrally managed.

Other environment-related efforts and products on display that contribute to reducing CO2 emissions included Fujitsu Manufacturing Industry Solution PLEMIA EcoLink, which facilitates efficient survey reporting for green procurement, and facility management services and AZCLOUD SaaS teraSpection, which support smart facility management and inspection through tablets.

ICT x People < Conservation of Nature and Living Things > Section

Birdcall recognition software to detect the calls of Blakiston's fish owls

The ICT x People < Conservation of Nature and Living Things > Section presented Fujitsu's ICT that supports conservation activities of the Wild Bird Society of Japan involving endangered wild birds and efficient measurement and vegetation surveys of forest resources.

This section introduced birdcall recognition technology, which enabled automated and efficient survey of Blakiston's fish owls. Special software assists natural environment surveys by automatically recognizing calls recorded with an IC recorder and identifying all the animals present. It used to take about one hour to process three hours of recorded data, but the birdcall recognition software reduced the analysis time to two to three minutes.

Taking pictures of a forest from a drone

Another product on display was a forest perspective measurement service Morisshi-Lite (tentative name, demonstration only) which helps formulate forest conservation plans by taking pictures of forests from a drone above and analyzing the pictures.


On December 12, 2015, the Paris Agreement--a new framework on reducing global warming--was adopted at the 21st Conference of the United Nations Framework Convention on Climate Change (COP 21), 18 years after the Kyoto Protocol. As global awareness of the environment is growing, Eco-Products 2015 successfully attracted a large number of environment-conscious visitors, both young and old.
