Concentrating our expertise on environmental revitalization

In this day and age when businesses are held responsible for the conservation of the environment, we understand that companies have a social obligation to create a system in which resources can be cycled back and reused. As of present, we are in the process of recycling from various waste materials.

We are the forerunners in the race for resource recovery. The Kochi Concrete Recycling Center, built in 1989, successfully reprocessed waste concrete and asphalt into reusable construction materials due to improvements in the mineral crushing equipment at our factory. Later in 1998, we developed a dehydration facility for construction sludge. In 2001, we obtained a patent for our kneading technology, which allowed us to knead construction waste. We also coordinate with Jinzenji Unso Co., Ltd and our other group subsidiaries to develop techniques in alternative waste disposal including the disassembly of dioxin-contaminated incinerators and the regeneration of contaminated soil.
