The company has continually increased its cement capacity, which today amounts to more than 5Mta.
Its Hon Chong cement plant, situated in the southern Vietnam province of Kien Gang, produces 2Mta of cement. The plant has been designed to facilitate the co-processing of waste materials from a wide range of industries including footwear, paper, plastics and agricultural wastes such as rice husks. Since 2007 Holcim has used its Geocycle brand name in Vietnam to provide safe and environmentally-sound solutions by co-processing technology in cement kilns.
