Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.
