My research aims to improve the energy efficiency of the numerous small-scale waste incineration facilities in Japan and reorganize them into a more rational system. To this end, we visited a Waste-to-Energy (WTE) facility in Italy renowned for its exceptional energy utilization rate, and one of the largest in Italy. This advanced plant not only generates electricity from steam produced by incineration heat but also supplies hot water to Brescia’s extensive district heating network. In addition, it features a highly sophisticated system for recovering additional heat via flue gas condensation, achieving an exceptional overall energy recovery efficiency of 98%.
Compared to facilities in Japan, the scale of Termoutilizzatore A2A Brescia is truly remarkable. Its investment in heat recovery equipment and its actual heat utilization rate are significantly higher. Moreover, the close collaboration between the incineration plant and the city to build a district heating network that meets the entire city’s heat demand is a highly rational and effective model.
