Gypsum plasterboard waste as a raw material for the production of new eco-friendly plaster composites: the case of the Spanish industry

This study aims to identify the possibilities of recycling plasterboard waste from industrial and construction and demolition works. Plasterboard waste samples from the main Spanish manufacturers were analysed in different conditions to assess their potential recyclability with the minimum environme...

description This study aims to identify the possibilities of recycling plasterboard waste from industrial and construction and demolition works. Plasterboard waste samples from the main Spanish manufacturers were analysed in different conditions to assess their potential recyclability with the minimum environmental impact possible. Until now, other authors published contradictory information regarding the topic, as it varied greatly depending on the type of waste used. Thus, the main aim of this research is to help create a common recycling protocol to allow researchers and companies to carry out a proper treatment of this residue. The analysis aims to define the optimal temperature and heating time (when applicable) in order to achieve the mechanical performance requirements by standards. In that sense, it is important to note that the results achieved in this research are not only applicable to Spain, the largest producer and exporter of plasterboard on the European continent, but also to other European countries. The experimental procedure followed two possible scenarios. The first scenario (Phase 1) analysed the possibility of completely replacing commercial gypsum for construction (CG-C) with gypsum plasterboard waste with no previous heating treatment. A possible second stage (Phase 2) was contemplated, in which different temperatures and heating times were studied for the waste. Results showed that heating at 150 °C during 3 h was enough for all the producers to achieve an optimal mechanical performance. Also, the compressive strength of the best producer scenario reached 8.40 MPa, which was 38.7% higher than that of CG-C.
