星野産商 Company Profile

For the city. For the future. Contributing to society is our job.

Hoshino Sansho Co., Ltd. has over 40 years of experience in steelmaking slag processing for electric furnace steel manufacturers. Throughout this time, we have worked diligently to process slag and commercialize it as concrete aggregate. With support from various sectors, we were able to obtain JIS certification (JIS certified factory) for "electric furnace oxidized slag aggregate" for the first time in the country in 2006. Currently, our products are used in various applications, including wave-dissipating blocks, vibration control structures in buildings, and partition walls in reactor facilities. Additionally, in the field of medical waste, we have been handling industrial waste from medical institutions in Aichi, Mie, and Gifu prefectures for over 10 years since the system's inception, earning their trust. We believe that recycling breathes new life into waste, and it must not only be a recycled product but also an attractive product that cannot be replaced by anything else. As the establishment of recycling systems has long been a significant theme in Japanese industry, we will continue to strive for the further realization of "recycling" that truly establishes itself as a business.
