“…Expanded polystyrene can replace the conventional binders in emulsion paint such as PVA without altering the properties and performance of such a paint. Myint, Zakaria [69] employed recycled expanded polystyrene waste in paint formulation to replace the conventional alkyd resin that is used in some commercial paints. Their result revealed that 27% of waste polystyrene can be incorporated in paint formulation without altering its basic properties.…”

Over the years, waste recycling has been a growing concern among many nations of the world, especially in developing countries. Expanded polystyrene (EPS) is used in electrical/electronic appliances as a shock absorber and constitutes a reasonable percentage of the entire plastic waste. There are three methods of recycling expanded polystyrene: mechanical, chemical, and thermal recycling; each of the above methods gives rise to different products that are used in different applications. Expanded polystyrene is used as a binder in emulsion paint as a replacement for conventional binders; as a component of asphalt used in road construction; as a component of wood plastic composites; as a blend with silica and in concrete to produce lightweight construction material. This article studied the various applications of recycled polystyrene waste from mechanical, chemical, and thermal methods of waste recycling.

“…Several attempts have been made by researchers towards reclaiming EPS into useful products for various applications. Myint, Zakaria, and Ahmed 14 formulated a paint based on an EPS waste binder intending to replace alkyd resin. They reported an optimum performance at 27% EPS incorporation in the paint formulation which was comparable with commercial alkyd resin paint.…”

This research produced textile pigment printing paste using expanded polystyrene (EPS) as a binder, sodium alginate as a thickener, and ultramarine pigment. The printing paste production was optimized through response surface methodology, using central composite design (CCD). The dynamic viscosity of the produced printing paste samples ranges from 5200 to 5550.50 cP (Centi Poise). The Fourier infrared transform (FTIR) spectroscopy revealed the functional groups present in the printing paste. The result of the thermogravimetric analysis (TGA) conducted shows a first step decomposition of 94.14% that occurred at the range of 30.96°C–127.75°C. Differential scanning calorimetry (DSC) showed an endothermic transition at 119.44°C due to the absorption of energy during the breaking of printing paste bonds. Textile characterization such as wash fastness, croak fastness, and light fastness was carried out to determine the suitability of the print paste on cotton and polyester fabrics. The results of the fastness tests range from 4 to 5 for wash fastness, 3 to 4/5 for croak fastness, and 4 to 6 for light fastness. The optimum values of the model variables are thickener (50%), binder (40%), and pigment (5%). The performance of the printing paste as revealed from the results is moderate and comparable with textile printing paste suitable for commercial application.

“…Owing to its light weight, buoyancy, thermal insulation, dimensional stability, chemical resistance, electrical properties, hygienic appearance, low cost etc., EPS is used for a large number of applications. Today, global consumption of EPS exceeds 3 million tons with an increase of approximately 6% a year [2,3]. After use, EPS usually ends up in landfills or is incinerated.…”

a b s t r a c tExpanded polystyrene (EPS) constitutes a considerable part of thermoplastic waste in the environment in terms of volume. In this study, this waste material has been utilized for blending with silica-reinforced natural rubber (NR). The NR/EPS (35/5) blends were prepared by melt mixing in a Brabender Plasticorder. Since NR and EPS are incompatible and immiscible a method has been devised to improve compatibility. For this, EPS and NR were initially grafted with maleic anhydride (MA) using dicumyl peroxide (DCP) to give a graft copolymer. Grafting was confirmed by Fourier Transform Infrared Spectroscopy (FTIR) spectroscopy. This grafted blend was subsequently blended with more of NR during mill compounding. Morphological studies using Scanning Electron Microscopy (SEM) showed better dispersion of EPS in the compatibilized blend compared to the noncompatibilized blend. By this technique, the tensile strength, elongation at break, modulus, tear strength, compression set and hardness of the blend were found to be either at par with or better than that of virgin silica filled NR compound. It is also noted that the thermal properties of the blends are equivalent with that of virgin NR. The study establishes the potential of this method for utilising waste EPS.
