Iran: 70% of cement plants by capacity were reportedly using the low-quality heavy fuel oil mazut as cement fuel on 13 January 2024. Iranian Labour News Agency has reported that plants transitioned to the fuel from natural gas amid an on-going gas shortage. This has led to a rise in costs and increased pollution from cement plants.
Iran’s Cement Industry Employers’ Association said that the industry’s supply of natural gas has dropped to 7Mm3/yr, from 27M3/yr normally.
