A Comparative Study in the Execution of Gypsum Coatings under an Environmental Impact Perspective

The gypsum slurry used in coatings is a construction material that generates many residues. Despite the proven feasibility of recycling, the reduction of waste is still the best way of minimizing the environmental impact. Different technologies have been studied in order to replace its use. However, studies have shown that the losses in construction when using gypsum plasterboard panels are approximately 5%. Although gypsum plasterboard panels seem to be environmentally more suitable, it is necessary to do a comparative study to support the advantages of using plasterboard panels. The survey of aspects and impacts was carried out directly in the monitoring of the implementation procedures in work. For the impact assessment, the methodology took into account significance criteria, scope, frequency and severity. From the score attributed to these criteria was possible to assess the severity of impacts and define which finishes would be environmentally more suitable. As a result has been that the gypsum plasterboard panels causes less environmental impacts during the construction, in this evaluation we found 33 impacts unless that the coatings with gypsum slurry and their most appropriate use under the environmental point of view.
