Waste-to-energy treatment is an efficient energy recovery method and an important countermeasure against global warming. The supply of steam from waste treatment plants to industrial sectors presents a higher energy recovery efficiency than traditional waste-to-energy methods. However, its technical potential and economic benefits are not fully understood by policymakers. Furthermore, the regional characteristics and effects of neighboring land use, which affect the heat supply and demand, are not commonly analyzed. Therefore, this study evaluates the spatial steam demand of industries in the Aichi Prefecture by using the steam demand unit value per production shipment and the spatial value of manufactured goods shipments. In addition, this study evaluates the steam supply potential from waste treatment plants to industrial sectors based on the estimated spatial steam demand and the transportable distances. The results show that the steam supply from waste treatment plants to the industries has a great physical potential in Aichi Prefecture. From a cost–benefit perspective, plans considering a 1 km range can be profitable, but the profitability decreases as the distance increases and the no-profitability mesh number increases. To improve the energy recovery efficiency from waste, the location of waste treatment plant should be changed, and the efficiency of steam transport on both supply and demand sides should be increased.

废物转化为能源是一种有效的能源回收方法，也是应对全球变暖的重要对策。从废物处理厂向工业部门供应蒸汽比传统的废物转化为能源的方法具有更高的能量回收效率。但是，决策者尚未完全了解其技术潜力和经济利益。此外，通常不会分析影响供热和需求的邻近土地利用的区域特征和影响。因此，本研究通过使用每生产装运的蒸汽需求单位价值和制成品装运的空间价值来评估爱知县工业的空间蒸汽需求。此外，这项研究基于估计的空间蒸汽需求和可运输距离，评估了从废物处理厂到工业部门的蒸汽供应潜力。结果表明，在爱知县，从废物处理厂向工业提供的蒸汽具有巨大的物理潜力。从成本效益的角度来看，考虑1公里范围的计划可以获利，但是随着距离的增加和无获利的网格数的增加，获利能力将下降。为了提高废物的能量回收效率，应改变废物处理厂的位置，并提高供需双方的蒸汽输送效率。结果表明，在爱知县，从废物处理厂向工业提供的蒸汽具有巨大的物理潜力。从成本效益的角度来看，考虑1公里范围的计划可以获利，但是随着距离的增加和无获利的网格数的增加，获利能力将下降。为了提高废物的能量回收效率，应改变废物处理厂的位置，并提高供需双方的蒸汽输送效率。结果表明，在爱知县，从废物处理厂向工业提供的蒸汽具有巨大的物理潜力。从成本效益的角度来看，考虑1公里范围的计划可以获利，但是随着距离的增加和无获利的网格数的增加，获利能力将下降。为了提高废物的能量回收效率，应改变废物处理厂的位置，并提高供需双方的蒸汽输送效率。
