Company information
In recent years, awareness of environmental conservation and recycling has been increasing and becoming established. I believe that it is the responsibility of humans living in nature to protect natural resources and the environment—soil, water, and air—that are indispensable to daily life, as shared assets of the entire region and ultimately the entire planet. Tanaka Construction Co., Ltd. aims to contribute to local environmental conservation by developing, manufacturing, and selling recycling products that are beneficial for environmental preservation as a company that deals with "soil." As specialists in "soil," we want to contribute to the formation of a regional circular society by upholding the mottos: "No unnecessary 'soil' will be produced!", "Actively recycle usable 'soil'!", "Create high value-added 'soil'!", and "Environmental regeneration!"
