Oji Holdings Corporation (President: Masatoshi Kaku, Head office: Tokyo) and Shimizu Corporation (President: Kazuyuki Inoue, Head office: Tokyo) have jointly developed KAMIWAZA, a technology for improving the productivity of temporary construction using paper materials to contribute to achieving the Sustainable Development Goals.KAMIWAZA is a solution that uses paper materials as temporary construction materials used in civil engineering. By using paper materials that are easy to handle as a substitute for the steel and wood materials conventionally used as temporary construction materials, the burden on workers can be reduced and the productivity of temporary construction will improve. The paper material mainly used as the temporary construction materials are HiPLE-ACE®(*1) of Oji Interpack co., Ltd. and Hatosheet(*2) of Oji Kinocloth Co., Ltd*1) HiPLE-ACE®A corrugated board material with a three-layer structure used as a packing material for heavy loads, having a high shock absorption performance and high strength.(*2) HatosheetA nonwoven fabric that uses wood pulp as its main material, capable of controlling the diffusibility, retentivity, and volatility of the liquid it absorbs.
