CircuLite: Upcycling biomass/sludge ash into absorbent/antibacterial materials

Disposing ash costs millions of $ and needs transportation to landfills. Recycling ash for cement/soils has low values

AC Biode Exhibit overview image1

We upcycle biomass ash, sewer sludge ash into absorbent or antibacterial materials. Applications: masks, filters, soil improvement, wastewater treatment, cosmetics, capturing CO2, capturing oil from oil spills in the ocean, and more.

AC Biode Exhibit overview image2

CircuLite from ash have three colors: white, gray, and black. These are in powder form.

Zeolite and activated carbon have the similar function as CircuLite; however, CircuLite is the only one recycled from ash, and captures harmful substances not only physically but also chemically by its ion exchange structure. Thus, adsorption capability is up to 100% higher. Our business model is to provide engineering to owners of power plants or sludge incinerators and to get loyalty fees for selling CircuLite. We have already successfully completed two plants in Japan and Asia, and have received a contract from Sahacogen, Thailand. New applications are to capture CO2, nuclear waste, oil from oil spills in the ocean, and more. We are looking for pilot tests, providing samples, and potential clients

A wind turbine generator that can generate power even under typhoons and cyclones

It is expected to be a RE technology for regions that have not been suitable to install renewable energy so far!

Challenergy Inc. Exhibit overview image1Challenergy Inc. Exhibit overview image2

We are the world's first startup company to develop “Magnus Vertical Axis Wind Turbine (Magnus VAWT)". It is vertical axis type that can handle wind from all directions and utilizes "Magnus effect" generated by rotating a vertical cylinder instead of a propeller. Conventional propeller wind turbines stop operation at a wind speed of 25 m/sec, but Magnus VAWT can generate power up to 40 m/sec. The Magnus VAWT can cope with typhoons which are getting bigger due to climate changes and with the slower rotation speed of its rotating part, it can reduce environmental burdens such as noise and bird strikes.This technology is expected to be a renewable energy technology that can replace diesel generators, especially in island areas hit by typhoons and cyclones, and in mountainous areas.

Peaches From Fukushima

Following the Great East Japan Earthquake and the resulting accident at the Tokyo Electric Power Company’s Fukushima Daiichi Nuclear Power Station, large amount of radioactive substances were released into the environment, producing extremely large effects over a wide area. Over the past 10 years, with the cooperation of many groups and individuals, we have carried out decontamination projects and other environmental restoration projects on a scale never seen in the world before. In parallel with the recovery efforts, we have also carried out projects for the creation of new industries, including the introduction of renewable energy and other projects for eliminating carbon emissions, in cooperation with the Fukushima Innovation Coast Framework, the Fukushima prefectural government, and others. Fukushima Prefecture has declared “Fukushima 2050 Carbon Neutral", and is expanding the introduction of renewable energy with the goal of supplying producing an amount of renewable energy that is equivalent to 100% of energy demand in the prefecture.

Cost reduction, social acceptance and localization

TODA CORPORATION Exhibit overview image1TODA CORPORATION Exhibit overview image2

A 1:100 scale model of the floating wind turbine is displayed. The world’s first Hybrid Spar floater, which uses concrete on the lower part and steel on the upper part, was adopted. This enables both a reduction in construction cost and high stability in water. A 2MW demonstrative floating offshore wind turbine ‘Haenkaze’ was successfully installed in 2013. Commercial operation started in April 2016.
A demonstration project of the cost reduction and localization was started through the Goto Project, as parat of the first Japanese offshore auction won by Goto consortium led by TODA Corporation.
Social acceptance is key for decarbonization with floating wind. This effort, conducted by the Ministry of the Environment of Japan, is introduced in the video shown in Japan Pavilion.

JAXA, the Japanese core agency to develop satellites, is operating 6 satellites and developing various earth observation satellites that observe land, ocean and atmosphere for addressing the global challenges.
The data are publicized with free and open access to enhance people around the world to utilize those for various purposes. To understand the status of climate change, it is necessary to observe effective geophysical parameters globally with optimal spatial and timescales. Essential Climate Variables(ECVs) were specified internationally to identify and predict specific changes in the global environment caused by climate change. Currently, JAXA’s Earth observation satellites contribute to 26 ECVs, and the long-term satellite observation data is used in several reports including IPCC.

Sumitomo Forestry Co., Ltd. IHI Corporation Exhibit overview image2

Monitoring concept by weather and earth observation technologies

Tropical peatlands store vast amount of carbon and sustain global water cycle and biodiversity. However, overexploitation/fires have released 2.2 to 3.7 billion t-CO2/yr. This is equivalent to 6 to 11% of global emissions. Sumitomo Forestry (SFC) has realized sustainable forestry in Indonesia based on scientific knowledge; developed a management model preventing peatland from drying out and collected data over 10 years. SFC and IHI have teamed up to bring this sustainable model to the world, which tackle global climate changes by monitoring on ground and earth observation with AI. Ministry of Economy, Trade and Industry (METI) supports our development through promoting utilization of satellite data, such as HISUI, ASTER, PALSAR. We are planning to launch constellation of satellites in equatorial orbit to improve these observation technologies.

Carbon Negative Concrete "CO²-SUICOM"

"CO²-SUICOM" is a technology that absorbs and permanently stores carbon dioxide during the hardening process of concrete.

CO²-SUICOM Exhibit overview image1

CO²-SUICOM is a technology that can contribute to the reduction of CO² emissions of more than about 300 kg/m³ during the production of concrete.CO²-SUICOM can (1) drastically reduce CO² emissions during cement production by replacing more than half of the cement with special admixtures made from industrial waste or other raw materials with zero CO² emissions (reduction: approx. 200 kg/m³), and (2) a large amount of CO² is absorbed and fixed in the concrete by curing the concrte in a highly concentrated CO² environment (absorption amount: approx. 100 kg/m³). According to various research organizations (McKinsey, etc.), concrete absorption and fixation technology for minerals, including CO²-SUICOM, is expected to contribute to the reduction of billions of tons of CO² by 2030, which has the potential to exceed Japan's national emissions.

CO²-SUICOM Exhibit overview image2

CO²-SUICOM is the world's first commercialized carbon negative concrete technology.
In Japan, it is already used for construction of highways and paved roads, etc., and we are now promoting commercialization overseas. In order to decarbonize our society, The Chugoku Electric Power Company, Kajima Corporation, Denka Corporation and Landes Corporation has developed the technology, and Mitsubishi Corporation is in charge of commercialization overseas.
A CO²-SUICOM concrete block can reduce CO² emissions equivalent to what a cedar tree can absorb in a year. This is a break thorugh technology for concrete which is one of the most consumed materials in the world.With the power of CO²-SUICOM we aim to realize a sustainalble society by decarbonizing the global infrastructure.
