THE CUSTOMER

Bamboo Energy Co., Ltd. is involved in the power generation business exploiting biomass waste. The company is part of a larger Group that collaborate to the use of bamboo comprehensively, realizing recycling-type utilization: Bamboo Frontier Co., Ltd. collects bamboo from the surrounding area, the parts without branches and leaves go to Bamboo Material Co., Ltd. for processing into building materials and finally, branched leaves and chips (and cedar bark) go to Bamboo Energy Co., Ltd., for fuel.

THE NEED

The customer core process is the production of building materials made from bamboo. The process generates a certain amount of bamboo waste not suitable for the building materials production and needs thermal energy for the drying of the raw material.

The ORC responds to both the needs of valorising the waste to produce electric and thermal energy. The first feeds the parasitic consumptions of the plant and the second is for heat utilization of the plant.

OUR SOLUTION

As a result of the examination of NEDO* project about the energy supply system of Bamboo Energy, ORC cogeneration system has been adopted.

Thanks to the collaboration with our agent Daiichi Jitsugyo Co, Ltd., we delivered the ORC cogeneration system, which uses thermal oil, and determined to supply 995 kW of electricity and 3,995 kW of hot water, using biomass. The result is a combined heat and electricity supply model of biomass energy using bamboo not suitable for the building materials production and bark.
