Avdiivka Coke and Chemical Plant (Ukrainian: Авдіївський коксохімічний завод, romanized: Avdiivskyi koksokhimichnyi zavod, AKHZ) in Donetsk Oblast, Ukraine, was the largest coke producer in Ukraine and is owned by the company Metinvest,[1] which is in turn owned by Rinat Akhmetov, a Ukrainian oligarch.

[4] The plant was constructed in 1963 by the Ukrainian Soviet Socialist Republic to fulfil the coke needs of the nearby Mariupol Steel Works[5] as well as the availability of coal from local mines.

[9][failed verification] In July 2014 fighting during which Ukraine secured the city from the Russian separatists[10]) damaged the plant, which was hit by 165 mortar rounds during the conflict.

The letter also claimed that the town had been without water, heat and electricity for the previous six months and warned of the ecological catastrophe that could follow from further shelling of the plant.

[11] Much of the plant had been damaged and it was being managed from a Soviet era bunker underneath the site in order to avoid shelling.

[21] Months of heavy fighting for the plant followed during the Battle of Avdiivka (2023–2024), eventually involving Ukrainian reinforcements from the 3rd Assault Brigade and extensive Russian aerial attacks using glide bombs.

Before its destruction, the plant has seen considerable investment in environmental equipment and facilities including sulphur removal and heat exchangers to reduce energy consumption.
