Abstract Scope |
Ceramic bricks play an important role in the Brazilian economy and have red clay as a basic raw material for this industry. The aim of this study was to discuss the main environmental impacts related to the manufacture of red clay bricks, comparing conventional production versus the production of red clay bricks incorporated with stone waste. The environmental performance of red clay bricks in Brazil was evaluated with a Life Cycle Assessment study based on international standards ISO 14040 and ISO 14044. The main impacts of brick production are associated with atmospheric emissions (CO2), in the transformation phase. The incorporation of stone waste represents a possibility to reduce environmental impacts and improve the durability of the material, since the bricks incorporated with 5% by mass of stone waste increases the useful life 2.91-fold, when compared to conventional ceramic bricks, considering the sintering of the material at 950ºC. |
