“…The absorption bands for polystyrene are as follows: 3026 cm -1 C-H band related to the deformation of the aromatic ring; 2928 and 2851 cm -1 bands related to the asymmetric and symmetric stretching vibrations of CH 2 , respectively; 1600 and 1493 cm -1 C-C bands corresponding to the stretching of the aromatic ring; 1445 cm -1 band related to the bending vibration of CH 2 ; 1069 and 1028 cm -1 C-H bending vibrations of the ring plane; and 760 and 698 cm -1 C-H bands that correspond to the deformation of the aromatic ring out of the plane [27][28][29][30] . No changes were observed in the polystyrene spectra after 90 days of exposure in the simulated soil.…”

Composites consisting of waste cotton yarn (CF) from the textile industry and postconsumer expanded polystyrene (EPS) was followed during 90 days of exposure in simulated soil. The mechanical properties, morphologies and chemical natures of the composites were determined before and after exposure in simulated soil. The composites were made using a single-screw extrusion, a twin-screw extrusion and injection molding. The composites showed an increase of the mechanical properties nearly 50% in relation to the recycled expanded polystyrene (rEPS). After exposure in simulated soil the composites presented losses of mechanical properties. Evidence of the oxidation of the samples was demonstrated by the increase in the values of the carbonyl index after 30 days of exposure in simulated soil. Changes in the color of the surface of the sample were observed after 90 days of exposure and are due to the fungi and bacteria colonization on the surface.

“…Park et al (2003) reported a styrene yield of around 70 wt% at 450°C in a batch thermal reactor, but the yield was considerably higher when BaO or ZnO catalysts were used. Chauhan et al (2008) operated in a fixed bed reactor from 350 to 500°C under vacuum conditions, and they obtained a styrene yield higher than 80 wt% at 500°C. Jung et al (2013) used a fluidised bed reactor and the maximum yield was 59 wt% at 515°C (the highest temperature studied).…”

“…Expanded polystyrene (EPS) is widely used in insulation materials for protecting goods in transport, for food and electronics packaging, and for insulation in air conditioning systems, among many other applications 1. EPS products have relatively short life cycles compared to products made of polystyrene (PS); as a consequence, EPS is used only in special applications.…”

This study evaluated the mechanical, thermal, rheological, and morphological properties of virgin and recycled matrices and their composites with 20 wt % of curaua fiber. The recycling process of postconsumer polystyrene was carried out by grinding and extrusion. It was found that the recycling of expanded polystyrene did not have a major influence on the mechanical properties; however, the thermal stability was increased. The addition of curaua fibers led to increases in the tensile strength, modulus of elasticity, rigidity, thermal stability and melt viscosity of the composites. The composites made with the recycled matrix revealed higher thermal stability and melt viscosity than those made with the virgin matrix. Scanning electron microscopy characterization showed empty spaces where the curaua fibers had pulled out of the matrices in the fractured regions, indicating poor interfacial adhesion without the use of a coupling agent.
