    1) Making good use of wooden biomass

    Wooden biomass resources as the raw material of our products are wood fibers that are by-products from sawmills. Our Tottori plant and Okayama plant are located in the Chugoku Mountain District where so many sawmill industries are located and they can provided us with their by-product-wastes.

    “Wood plastic” is compound material of wooden biomass and plastic that is melted by friction heat during stirring them together in the melting mixer. This compound material will be molded into W-Board or pallet for distribution industry with large press molding machines (pressure: 3,000 ton class)

    2) Characteristics of wood plastic

    As wood plastic is compound material of wooden biomass and plastic, various kinds of physical properties of wood plastic can be obtained by changing the mix ratio of both raw materials.

    The wooden biomass is carbon neutral material and can reduce the environment burden much more when it is used much more. The fiber reinforced effect of wooden biomass can make
    1.the bending strength and bending stiffness higher than those of plastic single body,
    2.the expansion and contraction less sensitive to temperature change than those of plastic only
    3.and also obtain higher heat resistance.

    Making good use of these characteristics, our company provides distribution industries with the pallets. Wood plastic scarcely absorbs a rain fall level of water because plastic is very tightly filled into the gap among wooden fibers. Also, the plastic with hydrophobic property contains the cellulose with hydrophilic property within it and demonstrates capsule effect.

    3) Reduction of the amount of emission of carbon dioxide

    Not only through making good use of wooden biomass but also through applying recycling plastic as the raw material, our company is dealing with eco-friendly activities such as the conservation of forests and the reuse of pet bottle caps. Because the weight of our products is very light, which contributes to less oil consumption during the transportation .

    Our products have very large reduction effect to reduce the amount of emission of carbon dioxide.

    Our company has agreed with the Cool Choice Activity that has the target to reduce the amount of emission of greenhouse gas until the year of 2030 by 23% less than that of the year of 2013, and is challenging to spread out our products world-widely.
