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.

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.

Abstract Modifying environmentally harmful waste polystyrene foam as an efficient recyclable adsorbent for organic dyes is important. Amidation modified polystyrene (PS-SD) was prepared by the Friedel-Crafts reaction and N,N'-dicyclohexylcarbodiimide (DCC) dehydration condensation reaction of waste polystyrene foam. PS-SD had highly efficient removal performance for organic dyes in large volume water sample solutions, and equilibrium was achieved in 0.5 h. The maximum adsorption capacities for Methylene blue (MB) and Congo red (CR) were 881.62 and 1,880.91 mg/g, respectively, at room temperature according to the Langmuir adsorption isotherm (R2 > 0.99). The kinetic data of the two dyes followed pseudo-second-order kinetics. The removal percentage remained high (>85%) after eight filtration-regeneration cycles. Experimental results showed that PS-SD was an excellent adsorbent for water treatment with high recyclability and long life.
