  • Tamada Industries, Inc. Ltd. is in the tank manufacturing, sales, and related installation/maintenance service business. They manufacture SF (steel and fiber reinforced plastic) double-wall tank, which is an underground tank for storing liquid fuel and chemical products. It is designed for installation at gas stations and other facilities that store hazardous materials. Utilizing proprietary technology, this double-wall structure is comprised of a primary steel tank and a secondary FRP tank.

    The company has designed a detection interstice, or micro-space, between the primary steel tank and the secondary FRP tank. This is so that, even if leakage was to occur because of corrosion in the primary steel tank, soil pollution would be prohibited and the leak would be found.

    The FRP in the exterior layer of the SF double-wall tank features 500 times greater insulation than the asphalt used in covering single-wall tanks. In addition, it has 50 times the tensile strength and six times the shear resistance. As such, this allows it to become a durable cover as well as prevent corrosion when it comes to the interior layer. In addition, FRP is chemical-resistant.

    Many countries, including Japan, need SF double-wall tanks in order to comply with the environmental conservation regulations.

  • Using a combination of indigenous and scientific knowledge to design resource management model with ownership by residents
    Sustainable use of natural resources is essential for the future of rainforests in southeast Cameroon. This project will make accurate estimate of wildlife habitat density using camera trap and design a sustainable management model centering on monitoring by residents. A sustainable model for promising non-timber forest products (NTFPs) will be built by standardizing production and processing methods. Operators will be educated to ensure the model to be established in the region and the implementation process will be proposed to the Cameroon government.

    Preserve biodiversity with sustainable management of wildlife and non-timber forest products
    The establishment of forest resource management based on proactive participation by local residents will promote preservation of biodiversity in the rain forests of Congo Basin. Also, utilization of diverse forest resources including wildlife and non-timber products as well as improvement in lives of local residents through commercialization of forest products can be achieved in a sustainable manner.

  • The Universal Storage System, developed by TOTETSU MFG. CO., LTD., allows rainwater to be collected for storage. By removing sediments before storage, the stored water can be used for anything from agriculture to industry to everyday life. Typically, when rainwater goes through the gutters, it is wasted as it seeps into the ground. Instead, with this system, that water can be utilized.

    Because traditional concrete underground tanks are costly, water is usually stored in open reservoirs. This allows insects and contaminants to pollute the water, and also allows the water to evaporate. Totetsu’s system not only eliminates these issues, but also allows the land above the storage to be used for other purposes such as carparks or playgrounds.

  • Agriculture (irrigation): Porous System

    Tottori Resource Recycling Inc.
    To improve food security, Tottori Resource Recycling Inc. wanted to utilize our technology that could make people independent. That’s where Porous Alpha comes in. This system provides water-saving cultivation in dry areas by allowing water to remain in the soil. In the trials carried out in a greenhouse in Morocco, the crop yield increased by 20% with 50% less water consumption.

    The main raw material of Porous Alpha is used glass bottles. They are crushed into a powder, then calcium carbonate is added. Once heated, the material becomes amorphous and porous. This structure allows it to retain water. Porous Alpha provides water to plants when water is needed, which is the unique property to this technology.

    Glass bottles are made of silica sand and calcium carbonate is a natural raw material. Consequently, Porous Alpha comprises only natural materials, and it doesn’t harm the environment.

    This system has been implemented in many countries so far, to great acclaim.
