Dec 23, 2025
Mitsubishi UBE Cement Corporation
Mitsubishi UBE Cement Corporation (head office: Chiyoda-ku, Tokyo; President: Kazuto Hirano; hereinafter, “MUCC”) announced that, at the Board of Directors meeting held today, MUCC resolved to cease cement production at Kyushu Plant Kanda District 2 by around the end of March 2027 and to transform the district into a recycling promotion base specializing in various types of waste treatment, as described below.
The business environment for the cement industry continues to face pressures from declining domestic demand and reduced profitability in export markets. Against this backdrop, MUCC is advancing initiatives to strengthen profitability and improve asset efficiency, aiming to achieve sustainable growth and enhance corporate value over the medium to long term.
Meanwhile, as MUCC seeks to achieve carbon neutrality by 2050, a key effort is to improve its thermal energy substitution rate. In particular, MUCC considers it essential to expand the volume of waste treatment for thermal recycling at the Kyushu Plant, which has one of the leading cement production capacities in Japan, and to achieve a thermal energy substitution rate of 50% or more for MUCC as a whole.
Under these circumstances, in order to establish an optimal operation system and strengthen the competitiveness of its cement business, MUCC will cease cement production at Kyushu Plant Kanda District 2 by around the end of March 2027 and consolidate operations at Kyushu Plant Kanda District 1, thereby improving the efficiency of production facilities across the entire Kyushu Plant. In addition, to maximize the use of its technologies and further improve the waste treatment substitution rate, MUCC will develop Kyushu Plant Kanda District 2 as a recycling promotion base, utilizing existing facilities for crushing and packing waste plastics and removing chlorine and foreign materials.
MUCC will steadily execute these measures to further enhance corporate value and help build a sustainable society.
