Contribution to the Development of a Recycling-Oriented Society

Contribution to the Development of a Recycling-Oriented Society

We are promoting a switchover of raw materials and fuels used by cement production facilities at Denka’s Omi Plant (Itoigawa, Niigata Prefecture), replacing a portion of the natural minerals usually used with waste in an effort to step up resource recycling.
In addition, these facilities also accept byproducts from other production facilities within the Omi Plant’s premises and effectively utilize them as cement materials. By doing so, we are striving to help preserve the environment.
Looking ahead, we will take full advantage of a variety of technological elements suited for the processing of waste and byproducts. Ceaselessly pushing ahead with resource recycling, we will help develop a recycling-oriented society and thereby contribute to local communities.

Recycling of Urban Garbage Incinerator Ash

Our recycling operations also accept and utilize urban garbage incinerator ash as cement materials. Through these operations, we recycle a volume of incinerator ash, which is regularly emitted from incineration facilities in urban communities. In addition to contributing to the creation of a recycling-oriented society, this practice gives these communities more leeway before their final waste disposal sites are filled to capacity.
