Reducing the amount of plastic that imposes a burdem on the global environment is a universal thema.
In recent years, paper products and bioplastic products have begun to be used as altermatives to plastics, but It has not reached the level of "convenient, cheap and high-performance" plastic products, and has not grown significantly.
Despite the fact that MAPKA contains 51% of paper powder, which is a biomass, it has almost the same functionality as plastic products and can be molded using plastic molding technology, so it has steadily increased its market share.
In addition, recycling grades have already been commercialized because they can be remolded by crushing and repelling them in the same way as plastics.

HARUMI FLAG : Japan’s first full-scale hydrogen infrastructure(original Tokyo2020 Village area)

First hydrogen-based plant using only renewable(RE100 solution)

Utilization of renewable energy is a key towards the realization of carbon neutrality. Yet, a means for storing energy to adjust energy supply is required as renewable energies are unstable power source. Thus, we have exhibited a system that can respond to energy demands ranging from a small to a large scale supply using fuel cells where hydrogen is utilized.
We introduce various methods for utilizing hydrogen in our exhibition with Diorama;
1) supply of hydrogen to buildings and housing area through pipelines,
2) transportation of hydrogen to high demand areas for storage and utilization of the stored hydrogen,
3) utilization of the hydrogen generated from chemical factories, etc. as a by-product,
4) decentralized power source; electricity is generated from renewable energies and hydrogen is generated from the electricity for its utilization.

Perovskite cells and tandem cells meet different needs in urban areas

If we are to achieve carbon neutrality, we need to deploy more, and more efficient, photovoltaic power generation. However, current silicon (Si) solar cells are heavy and inflexible, which restricts where they can be installed, and there are limits to how far they can be improved. Two solar cells that Toshiba Group is developing will change this. Film-type perovskite solar cells are light, thin and flexible, and can be installed in buildings and locations inaccessible or unsuitable for Si cells. The Cu₂O tandem solar cell places a transparent copper oxide (Cu₂O) solar cell over a Si solar cell, boosting generation efficiency and producing much more power by area.

Protected tropical peatlands in Indonesia under Sumitomo Forestry management

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.

The side and plan view of Origami Comolevi Shade

Origami Comolevi Shade for Market space in Pandemic situation.

Tree shade is a nature-based solution for climate change that effectively cools hot cities. However, due to the high density of the urban environment, street trees with narrow canopy do not provide enough shade.
By 2030, when 70% of the world will be urban, the urban heat island will be promoted by climate change, further increasing the risk of heatstroke.
The hybrid nature-based solution must plant trees and invent artificial tree shading for cooling cities worldwide before urbanization comes.
Comolevi Origami Shade is a tree-like cooling shade, and anyone can use origami to make the shade.
Just cut and fold the paper, and anyone in the world can create tree shade. It is possible to take measures against the heat that no one leaves behind with a nature-oriented sunshade.

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 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.
