大坪GSI Company Profile

We are engaged in various businesses such as recycling, crushed stone, transportation, and civil engineering, among others!

At Ootsubo GSI Co., Ltd., we carry out the recycling treatment of construction waste soil, as well as the intermediate processing of rubble, inorganic sludge, ash, dust, and mineral slag, and we ship these as recycled products. Additionally, under the approval of rock extraction plans, we also produce and sell crushed stone for concrete, crushed stone for roads, and Hirokawa blue stone, among others. Recently, we have also introduced new products such as "artificial pumice," a multipurpose porous material recycled from glass, "EcoCal," an easy-to-use pelletized soil conditioner for agriculture, and "Katama SP," a simple paving material for parking lots and other uses. Please feel free to contact us if you have any requests.
