Reciclagem do gesso gerado pelo setor da construção civil na região oeste do Paraná

Abstract

With many technological innovations, civil construction has increasingly stood out as one of the most important pillars in our economy. However, the development of new techniques has also increased, in some situations, the consumption of new materials. The use of gypsum plaster for walls is an example of this. This has also increased the amount of waste generated by these materials. Therefore, it is necessary to adopt new waste management policies as well as studies that analyze the effectiveness of policies already adopted, such as Resolution 431/11 (CONAMA, 2011), which has changed the classification of gypsum Class B, making it recyclable. In order to identify the gypsum waste management process in the municipalities in the west of Paraná, this study was developed. Questionnaires and the application of direct observation protocols (DOP) were carried out in the municipalities of the sample, where first it was identified which municipalities in the region had the Municipal Solid Waste Management Plan (MSWMP) in order to diagnose the gypsum waste management process in these municipalities. The data made it possible to conclude that this region still needs many interventions and that not all the regulations related to gypsum recycling are being complied with, mainly due to the lack of recycling facilities for construction waste and gypsum waste, as well as faulty supervision procedures so that the plans and their determinations can be effectively carried out.
