A Story of Environmental Technology Weaving the Future - Innovation in Resource Recycling and Regeneration

The incinerator ash recycling technology developed by Takuma (August 1994) is a technology for recycling incinerator ash by crushing and mixing it with cement and reusing it as a building material. The technology is being introduced in cities such as Tokyo and Osaka as an environmental technology that reduces conventional landfill disposal and makes effective use of urban waste.

The solar production technology for hydrogen gas (November 2002) is a breakthrough technology developed by a research team at Pennsylvania State University. It produces hydrogen without the use of fossil fuels through electrolysis of water using a titanium dioxide catalyst. The state of Pennsylvania has recently been selected as the site of a hydrogen hub, and commercialization of this technology is accelerating along with the use of renewable energy.

Soil remediation technology using genetically engineered sunflowers (2020s) is a technology developed in New Jersey. Genetically engineered sunflowers absorb lead and cadmium in soil twice as efficiently as conventional technology, and are effective in reducing remediation costs by about 30%. It is attracting attention as a new possibility for environmental remediation.

Arsenic removal technology using ferns with nanoparticles (2020s) was introduced in California. Plans are underway to clean up 800,000 square meters of contaminated soil in 10 years.

The water purification technology utilizing fermented microorganisms was developed by the Ehime Prefectural Industrial Technology Center. By utilizing microorganisms used in fermented foods, such as yeast, lactic acid bacteria, and fermented soybeans, this approach is different from conventional wastewater treatment methods. This technology, which also reduces sludge and eliminates odors, is a new option for sustainable water quality management.

Lignin-based recycling chemical industry technology (Mie University) is a technology that separates plant-derived lignin and reuses it as bioplastic or polyester. This is expected to reduce dependence on fossil fuels and build a sustainable chemical industry.

Carbonized wood technology (April 2003) was developed by RITE (Research Institute of Innovative Technology for the Earth). This technology carbonizes moso bamboo (moso bamboo) and uses it as a soil conditioner and deodorizer, and approximately 1 million tons of bamboo are expected to be carbonized annually. It is expected to reduce CO₂ emissions.

New Wood" (April 2003), a biodegradable plastic, was developed by Matsui Co. This new material is a mixture of wood flour and biodegradable resin, and can decompose 30% faster than conventional plastics. It is also used in automobile parts for Toyota and Honda, with an expected annual production of 5,000 tons.

A wind/solar hybrid power generation system (April 2003) was installed in Osaka City. The system, which combines 26 wind turbines and 39 solar panels, aims to reduce annual CO₂ emissions by approximately 30 tons.

Solar Thermal Power Generation and Seawater Desalination Technology (April 2003) was developed by Duke Solar Energy, which uses surplus heat from solar thermal power generation to desalinate 100,000 liters of seawater per day. It is expected to be a solution to water shortages, especially in arid regions and developing countries.
