The French cement company Lafarge has said that it cannot account for more than half the workers at its major cement factory in Indonesia after the tsunami that struck the area. Lafarge’s boss Bernard Kasriel says they had 625 people working at the plant and 345 of them are missing. The plant is in Lhonga, near Banda Aceh. It is one of 13 that Lafarge has in the region hit by the tsunami.The company employs 6,400 people in the effected area and 10,758 in the whole Asia Pacific region. Lafarge has launched its own relief effort, initially sending 200 tons of supplies including food and medicines. It also intends to provide psychological support for its workers, their families as well as the company’s clients and people in the surrounding area. Of the 625 workers at Lhonga, 280 are known to be alive. The plant contributes between four and five million euros per year to Lafarge’s profits.
