Recycled waste polystyrene foam can be used as heat-resistant construction material, which helps reduce white pollution, benefits the renewability of resources, and brings a good economic and environmental return. In this paper, non-autoclave aerated concrete is made, which uses foam of polystyrene as its packing material，it also gives a research on performance of polystyrene-aerated concrete materia composition.

Presents the results of research on the development of a method for joint utilization of polystyrene foam and brick waste with obtaining a polymer composite material for the production of wall cladding products. This method consists in grinding the waste polystyrene foam with their subsequent dissolution in carbon tetrachloride and cold mixing the resulting solution with a crushed brick. This method reduces the energy intensity of production, eliminates thermal decomposition of the polymer binder during processing and makes it possible to jointly dispose of two types of large-tonnage waste. Products that can be obtained from the developed material, according to the values of frost resistance and water absorption, meet the requirements for products for external facing of walls and sole plates of facades.

Polystyrene is used in a wide range of applications in our lives, from machine housings to plastic cups and miniature electronic devices. When polystyrene is used, a large amount of waste is produced, which can cause pollution to the environment and even harm biological and human health. Due to its low bulk density (especially the foamed type) and low residual value, polystyrene cannot be easily recycled. Often waste polystyrene is difficult to recycle. In this paper, waste polystyrene has been modified by using acetic anhydride which caused a crude oil flow improver. The results showed that modified polystyrene improves the flow properties of the crude oil, reducing the viscosity and the pour point of the crude oil by up to 84.6% and 8.8 °C, respectively. Based on the study of the paraffin crystal morphology, the mechanism of improving the flow capacity of crude oil by modified polystyrene was proposed and analyzed.

Development of rotary forcespinning (RF) to synthesize fibers has been done. High speed motor driven centrifugal force becomes a major factor in the formation of fibers. RF apparatus consists of three main parts namely the motor system, the collector, and the heating system that serves to regulate the temperature and humidity around the motor. The liquid polymer was poured in the motor holder and rotated at high speed so that the liquid was dropped from the tip of the needle to the collector in the form of fibers. In this study, the liquid polymer was from waste polystyrene foam (styrofoam) soaked in acetone at a certain ratio. The observation was done with the digital microscope up to 1000 times of magnification. The produced styrofoam fibers were similar to homogeneous and smooth cotton with an average fiber diameter in micrometer. The utilization of waste styrofoam into the fibers is expected to reduce the environmental problems caused by waste styrofoam.
