Abstract
The heating up in the civil construction sector, the red ceramic industries in the Cariri-CE region had an increase in the production of products, resulting in an increase in the consumption of raw materials and becoming one of the sectors that generate more waste in the region. The increase in the amount of waste is mainly due to the lack of qualified labor, little technology and lack of quality control, which have contributed to obtaining products with properties below expectations and which, in many cases, do not meet the technical standards, making it unfeasible for consumption and thus resulting in high product losses, generating a very large amount of waste. The generation of waste becomes an even more intense aggravating factor when: a large part of the waste does not receive the correct destination, being thrown into nature, around the factory itself,
which possibly should be an area of permanent environmental preservation. This study aimed to evaluate the inclusion of the residue in the clayey mass for the production of ceramic products, replacing less plastic (lean) clay, as a way to reduce the irreversible environmental impact caused by the indiscriminate disposal of the residue. From the analysis of the physical, chemical and mechanical properties studies, the addition of the residue to the ceramic mass in replacement of the less plastic (lean) clay proved to be favorable for the production of bricks.
