植物衍生的可再生资源有潜力同时生产高附加值产品，如食品，与能源，如电力和火力发电。由于热供需的地理和时间差距，发电厂可再生能源产生的大部分热量已经被丢弃。在本研究中，我们的目标是为利用当地可再生资源的区域热电联产（CHP）工厂设计有效的工业共生（IS）。IS的实际区域采用了以种植甘蔗为基础产业的日本种子岛。通过对糖厂能量流动的热力学分析，证明了大量的热量从糖厂被丢弃，即使热量的质量足以用于发电或其他能源需求。部分原因是一些可再生能源在食品或其他高附加值产品的生产中被视为废物。同时，定义并分析了综合利用当地可获得的木质纤维素生物质以提高现有甘蔗渣基热电联产系统的运行比率的方案。在有糖生产和没有糖生产的两个时期，可以通过减少能量损失和通过IS获得额外的热量和电力。
Plant‐derived renewable resources have the potential to enable the simultaneous generation of high‐value‐added products, such as foods, with energy, such as electricity and thermal power. Much of the heat cogenerated from renewables in power plants has been discarded because of the geographical and temporal gaps in heat supply and demand. In this study, we aim to devise an effective industrial symbiosis (IS) for a regional combined heating and power (CHP) plant utilizing local renewable resources. For the actual region of IS, the island of Tanegashima in Japan was adopted, where sugarcane is planted as a base industry. Through a thermodynamic analysis of the energy flows in a sugar mill, it was demonstrated that large amounts of heat were discarded from the sugar mill, even though the quality of heat was high enough for power generation or other energy demand. This is partly because some of the renewables have been regarded as wastes in the production of foods or other high‐value‐added products. At the same time, scenarios were defined and analyzed on the integrated use of locally available lignocellulosic biomass to increase the operation ratio of an existing bagasse‐based CHP system. Through both periods with and without sugar production, additional heat and power can be made available by decreasing the energy loss and through IS.
