Thermal waste transformation plants (waste incineration plants) are a strong architectural accent in the existing site context. They often function as power plants or combined heat and power plants, producing heat and/or electricity by recovering energy from flue gases. The main objective of this study was to demonstrate the relationship between the architectural quality and protection of the natural environment through the technological solutions applied. The indirect aims of the study include the demonstration of the educational message conveyed through architectural and environmental solutions. The relationships defined by the objective were verified in comparative studies of eight operating waste incineration plants in Poland, located in: Bialystok, Bydgoszcz, Konin, Krakow, Poznan, Rzeszow, Szczecin, and Warsaw. The results were presented in three problem areas: (i) architectural quality, (ii) environmental solutions, and (iii) educational message. The results of the study led to the following conclusions: (i) waste incineration plants operating in Poland show a relationship between the architectural quality and broadly understood pro-environmental solutions, (ii) and all waste incineration plants operating in Poland show educational solutions.
