Final Considerations The implementation of this study pointed out the issue of environmental liabilities arising from the extraction of clay, an important mineral resource for the building industry in which Brazil is among the largest exporters. As a result of this activity, there are environmental aspects which end when the exploitation finishes. In this regard different modes of socioenvironmental impacts take place, according to the nature of the extracted material and the conditions in which exploitation operations are conducted. When the mining operations are processed in urban areas, the negative outcomes are summed up in the physical impacts of a social nature. As the exploratory mode, mining can trigger air pollution, noise, visual, water resources, affecting the society at different levels. The environmental damage takes shape at the close of exploratory practice, which can occur due to the exhaustion of the deposit, the impossibility of economic exploitation or the effect of intervention of the government. In this regard, the study searched to point out the possibility of recovering a specific type of environmental liabilities, especially the abandoned pits of clay extraction. The outlook takes into account the predicted stability of the ground and it is simple to carry out and it can be extended to other similar situations where conditions of physical and chemical stability, layout and size of the pit are permissible. Finally, the mining should be assessed in its entirety from the stage of research and implementation to the recovery phase after exhaustion of the deposit, always taking into account the externalities that are installed with the production process. The need to consider the most likely balance possible between mineral exploration and environmental deterioration constitutes a challenge of prime importance for mining. The lakes resulting from clay extraction pits by Santa Maria Ceramics have environmental conditions that allow the cultivation of fish in semi-intensive system. The tambaqui and pirarucu exhibited satisfactory performance when cultivated in tanks installed in clay mining pits. With the recovery of degraded areas by the extraction of clay for the fish culture, the pressure on fish stocks will be reduced and thus it will contribute to the preservation of pirarucu and tambaqui species today, threatened of extinction, in the main rivers and tributaries of the river the Amazon basin. Other fish species should be evaluated for their productivity when grown in semiintensive pond in clay mining pit. After completing the calculations for implantation and production using this model, it can be seen that this branch of activity has a relatively low initial cost, because it uses only areas already dug to extract clay. So when it is compared the cost of production with the sale price of the fish, it is clear that the costs are offset by a good margin. 34 Estratégica, vol.10(02), dezembro.2010
Considering the hypothesis, it appears that with the implementation of aquaculture activity it can mitigate areas of environmental liabilities generated by the extraction of clay. And yet, it presents a competitive advantage for the company as it becomes a profitable alternative. For the data presented in the activity of fish culture it was achieved U$ 149,946.00 as gross revenue, U$ 40,408.40 for the total costs and U$ 109,537.60 for the net earnings.
