mid March after disagreements with the company to implement expansion works were settled, the Yemen Cement Industry Corporation has said.The project aims to raise the capacity of the factory to 1.2 million ton a year.The corporation has agreed with a Chinese Company to carry out the plant expansion at a cost agreed earlier estimated at $ 113 million, deputy director of the corporation Muhammad Shnieve said.The drop in the prices of basic materials such as iron globally convinced the Chinese company to stop seeking more than the sum to implement the project, Shnieve said.The corporation also plans to establish a stone coal unit instead of mazut with the aim to start using stone coal to produce cement and to reduce production costs, he said, pointing out that the stone coal will lower the costs of cement production by 60%.The corporation will generalize the use of stone coal at all Yemen cement plants, a move which is expected to help the corporation avoid problems associated with the use of mazut which is expensive and sometimes not available, he added. The first phase of the stone coal unit would be implemented at the Bajil Cement Plant at a cost of $ 16 million, he said.
