Three companies collaborate to use 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. Branched leaves and chips (and cedar bark) go to Bamboo Energy Co., Ltd., for fuel. The latter company mentioned is our end-customer, involved in the power generation business exploiting the biomass waste.
The customer core process is the production of bamboo panels. The process generates a certain amount of bamboo waste not suitable for the panel production and needs thermal energy for the drying of the raw material.
The ORC responds to both the needs of valorising the waste wood to produce electric and thermal energy. The first feeds the parasitic consumptions of the plant and the second is used in the form of hot water in a belt dryer.
As a result of the examination of New Energy and industrial technology Development Organization project (NEDO) 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, 4,051 kW of thermal oil and 2,800 kW of warm water, using biomass. The result is a combined heat and electricity supply model of biomass energy using waste bamboo and bark.
