Japan: UBE Mitsubishi Cement (MUCC), Osaka Gas, Daigas Energy and Seibu Gas have successfully tested natural gas co-firing at MUCC’s Kyushu Plant in the Kurosaki area. Using a newly developed burner, the companies replaced 40% of coal with natural gas at commercial scale without affecting kiln stability, product quality or environmental performance.
The burner was developed using MUCC’s coal combustion expertise alongside Osaka Gas and Daigas Energy’s gas combustion and simulation technologies, with Seibu Gas supplying natural gas from LNG tank trucks. MUCC said the trial paves the way for full-scale implementation and supports future use of e-methane in cement kilns.
MUCC aims to cut CO₂ emissions by 40% by 2030, compared to 2013 levels, and achieve group-wide carbon neutrality by 2050 under its medium-term management strategy “Infinity with Will 2025 – MUCC Sustainable Plan 1st STEP.”
