Abstract:
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.
