Lafarge Cement would construct a cement plant in Langkat, North Sumatra, with an investment of Rp 5 trillion. The plant would have an annual production capacity is 1.5 million tonnes. One of the reasons to build a plant in Langkat is the amount of raw materials in the area, which is thought to be sufficient for a 30-year period. After building the plant in Langkat, Lafarge also plans to build a cement factory in Java. Lafarge Cement earlier owned a cement plant in Aceh, with a production capacity of 1.6 million tonnes per year, but it was devastated in the tsunami in 2004. Lafarge spent US$300 million on renovating its Aceh plant. "The government promised to accelerate the permit process and the ministry hopes the plant will be built early next year. If the required documents are completed, the permit can be issued in one month," said Mohamad Suleman Hidayat, industry minister, Indonesia. Hidayat added that every year, the local cement demand increases by 7-10 per cent or four million tonnes. Demand in 2015 is projected to surpass 55 million tonnes. To meet the demand, the government plans to build two factories with a production capacity of two million tonnes per year. Besides Lafarge, Chinese cement company, Anhui Conch Cement Company Ltd would construct four plants in Indonesia.
