“…In 2006, Karaman et al [30] obtained PET waste from recycled plastic bottles, using it as an aggregate in a gypsum matrix at weights of up to 20% of the added gypsum. Recently, Vidales-Barriguete et al [31] recovered pellet waste (heterogeneous mixture of thermoset and thermoplastic polymers), using them as aggregates in gypsum plaster with enhanced mechanical properties.…”

The use of gypsum as an indoor coating material for buildings is very extensive. This means that huge amounts of gypsum waste are generated daily worldwide. Therefore, many researchers in the last years have been working on the generation of new gypsum-related materials and products that incorporate recycled gypsum waste as a replacement for the commercial one. On the other hand, trying to reduce the large amounts of plastic generated globally each year, several studies have used different types of plastic waste as aggregates for the development of new construction and building materials. However, up to now, no previous studies have been found in which any type of plastic waste has been used as an aggregate in a recycled gypsum matrix. This paper presents a study in which two different types of waste were mixed for the development of new gypsum plasters: unheated gypsum waste from industrial plasterboard production (GPW) and polycarbonate (PC) waste from rejected compact discs (CDs) and digital versatile discs (DVDs). In this sense, the mechanical and thermal performance of plasters was evaluated. Finally, in order to evaluate the changes in the microstructure of the composites, a scanning electron microscopy (SEM) analysis was conducted. The results showed a good performance of the new composites when both types of waste were combined in the mixes. New lightweight eco-efficient plasters, completely recycled, with enhanced flexural strength (by 14.8%), compressive strength (by 26.8%), and thermal conductivity (42.8% less), compared to the reference material, were achieved.

“…We can see that these conclusions are similar to the previously mentioned investigations regarding the properties of plasterboard with added plastics. In general, the water absorption capacity, the thermal conductivity, and the mechanical strength decreases [34,41] as the plastic weight percentage in the mixture increases. However, none of these investigations included the evaluation of the interaction between the effect of plastic waste and the preparation variables such as stirring time, PMHS dosage, and drying temperature after the setting of CaSO 4 •2[H 2 O].…”

New composites produced with recycled waste are needed to manufacture more sustainable construction materials. This paper aimed to analyze the hygrothermal and mechanical performance of plasterboard with a polymethylhydrosiloxane (PMHS) content, incorporating recycled PET microplastic waste and varying factors such as PMHS dose, homogenization time, and drying temperature after setting. A cube-centered experimental design matrix was performed. The crystal morphology, porosity, fluidity, water absorption, flexural strength, and thermal conductivity of plasterboards were measured. The results showed that incorporating recycled PET microplastics does not produce a significant difference in the absorption and flexural strength of plasterboards. However, the addition of recycled PET reduced the thermal conductivity of plasterboards by around 10%.

The existence of plastic waste, such as used plastic sacks in large quantities, is a crucial problem for the environment and health because of its very low biodegradability. Therefore, reusing plastic sack waste as reinforcement in gypsum composites is a major research issue. This study investigates the mechanical and physical properties of gypsum composites reinforced with fiber layers from plastic sack waste. Gypsum composites are produced using casting gypsum flour as the matrix and various fiber layers from plastic sack waste (1, 2, 3, 4) as reinforcement. Gypsum-based laminated composites were tested for density, flexural strength, and compression. The behavior of mechanical, physical, and damage properties is studied to see its suitability as a building material. The results showed that gypsum composites' density decreased with increasing sack fiber layers. The density of gypsum composites ranges from 1064-1199 kg/m 3 , with a maximum value in samples with 100% gypsum. The flexural strength of gypsum composites ranges from 2.21-4.10 MPa, and the compressive strength ranges from 3.5-6.66 MPa. Increasing the number of layers of plastic sack fibers reduces density, flexural strength, and compressive strength. However, all the mechanical properties of gypsum composites met the requirements of the EN 13279-2 standard. Failure of fiber delamination with the resulting matrix is the main cause of the decrease in mechanical strength.
