Cement, a Key Material Contributing to the Development of Civilization

Used in roadways, bridges, dams, airports, buildings, waterworks and a host of other applications, it would be no exaggeration to think of cement as providing a city’s “bones.”
Mitsubishi Materials’ cement has been used in Abeno Harukas and numerous other high-rise buildings in city centers in Japan, as well as Colorado River Bridge atop the Hoover Dam—a historic structure in the United States.

Business Summary

Kyushu PlantKyushu Plant

The Cement Business has constructed a wide range of business structures to handle everything from the production and sale of various types of cement, ready-mixed concrete and secondary cement products to comprehensive construction. In addition to Japan, we have manufacturing and sales locations in the United States, China and Vietnam, through which we contribute to the building of social infrastructure in a host of countries.
We have cement plants at four locations across Japan. Of these, the Kyushu Plant is our main plant and the largest in Japan in terms of production capacity. These plants make a proactive effort to absorb society's waste, detoxifying it at high temperatures of around 1,450°C and utilizing its thermal energy and making effective use of it as alternative cement materials.
In North America, we operate a cement plant in the state of California. There, we have created a vertically integrated system spanning cement manufacturing, ready-mixed concrete and the aggregate business. We are working to maximize our performance through operations in countries around the world and aim to be a major player in the Pacific Rim.


Targets and Strategy

Long Beach Terminal (U.S.A)Long Beach Terminal (U.S.A)

Aiming to be the global leader in return on assets (ROA) in the cement business, in Japan we are making use of our comprehensive Group capabilities to expand the environmental and recycling businesses. In response to vigorous demand in North America, we are reinforcing our cement supply structure, such as by enhancing a terminal there. In emerging markets, we are responding to infrastructure demand by entering into tie-ups with local firms and building new cement factories and terminals.



Quintupling Our Processing Capacity for Recycling Waste Gypsum Board

Waste Gypsum Board Powder Waste Gypsum Board Powder

Gypsum board is widely used in building walls and ceilings because of its excellent strength and strong insulative and soundproofing properties. Large volumes of waste gypsum board are generated, however, as buildings age and are dismantled. Some of this waste is being recycled as resources for new gypsum board and ground improvement materials, but much of it currently ends up in landfills.
Mitsubishi Materials has developed a proprietary method for safely processing waste gypsum board and reusing it as a cement material by incinerating powdered gypsum board in high-temperature cement kilns (at around 1,450°C). We have also quintupled our Kyushu Plant's ability to process gypsum board.
