A reciclagem e a reutilização com o reaproveitamento do gesso

Abstract

The development of the evolutionary society goes parallel to the development and constructive evolution of new structures for housing and for the professional work of human beings, with that the creation and applications of diverse materials found in nature have becoming sources of studies of diverse works academics to perfect the constructions knowing that even nowadays, even with the advencement of technology, there is a great waste of material takes place, with this the civil construction industry chasing the economy of materials used in the works and the demand to reduce the time execution of the constructions has created a growing demand for the extraction and application of gypsum plaques in the constructions, considerably increasing the use of this material in the works, becoming one of the most consumed materials in the execution of finishing works or reforms. However, a worrying problem is related to the amount of wast generated by it. It is considered that the destination of this generated waste occurs in a precarious and inadequate way, contaminating the environment. The improper disposal of plaster waste in contact with other materials can alter its chemistry and contaminate the soil and groundwater, polluting the environment in which we live. This happens due to the composition of the physical and chemical characteristics of the material that in contact with other materials can change and become a toxic product, even harmful to human, plant and animal health. Through bibliographic reviews and laboratory test studies, this work presents in a clear and objective way the recycling process and its application, focusing on the viability and reuse of the plaster wast, having as some parameters research and scientific studies elaborated in this area, using ABNT standards, resolutions of the National Council of Environment - CONAMA, and statistics prepared by the National Department of Mineral Production - DNPM. In this line of thought, this work proposes the reuse and reuse of the mentioned material in the plaster processing industry, given the research and laboratory tests reports presented on technical feasibility satisfaction demonstrating its chemical composition. Sustainable development requires a reduction in the consumption of finite natural and non-renewable primary materials removed from the environment in order to minimize the environmental impacts generated.
