At our Omi Plant (Itoigawa, Niigata Prefecture), we are promoting recycling in cement production by replacing some of the natural minerals usually used as raw materials and thermal energy with waste and byproducts.
As part of our ongoing activities for zero emissions, the Omi Plant also accepts waste and byproducts from our domestic production bases throughout Japan and makes effective use of them as raw materials and as a thermal energy resource for cement, thereby keeping external emissions as low as possible.
Looking ahead, by taking full advantage of a variety of technological elements suited for the processing of waste and byproducts, and pushing ahead with recycling, we will continue to contribute to a recycling-oriented society.

Recycling of Waste and Byproducts in Cement Production

In our recycling operations at the Omi Plant, we accept and utilize waste and byproducts from the auto, power, steel and other industries, as well as urban garbage incinerator ash and sewage sludge generated by local governments, as raw materials for cement and as an alternative thermal energy resource. By recycling waste and by-products from various industries, we help extend the life of final disposal sites and reduce the burden on the environment.
