“…As similarly found in other properties (UHT and OHT, flexural, and QSI), the addition of 5 wt% of granite dust has also reduced the ILSS. The reduced mechanical performance when nanofillers modify composite materials has been discussed by numerous researchers [ 13 , 16 , 26 , 28 ]. A similar reason was reported, whereby the agglomerated structure of the modified matrix resin caused stress concentration, thus leading to composite failure.…”

“…Granite dust is a waste material that can potentially be used as a reinforcement due to its excellent properties, such as high modulus of elasticity and strength [ 23 , 24 , 25 , 26 ]. Granite dust is also classified as an industrial waste that can threaten the environment.…”

“…Owing to its chemical composition (i.e., alumina, silica, and magnesium, which are excellent fillers), granite dust has the potential of being used in polymer composites. Awad et al [ 26 ] investigated the effect of different granite dust weight percentages on the flexural properties of HDPE composites. It was indicated that 50 wt% of granite dust in HDPE can increase flexural strength, while a weight percentage of higher than 50 wt% can lead to particle agglomeration, which would reduce the performance of the composites.…”

“…A review of the previous literature showed that no specific work has been conducted to investigate the modifying effect of granite dust in the polyurethane matrix on the mechanical properties of basalt/glass composites. Most granite dust research was developed in various construction applications and building materials using bottom fine granite aggregate to replace natural sand and cement in concrete, filler material for roads, and manufacturing bricks and tiles for construction, infrastructure, and building [ 23 , 24 , 25 , 26 , 27 ]. Most of this research used bottom granite dust that is collected after the grinding or cutting process of granite stone; meanwhile, in this research, the granite dust used is a fine fly dry granite dust that is collected from the filter after drying, blowing, and heating at an elevated temperature of 200 °C during the preparation of concrete mixture at the quarry plant.…”

The granite processing industry generates large amounts of bottom granite dust waste every day. After the drying and heating process of concrete mixture production, the granite dust is blown and collected in the filtering nozzle. This very fine particle granite dry fly dust, with a particle size maximum distribution of 500 μm, can easily be blown away by wind and cause serious environmental impacts. The use of this waste material would be an effective way to reduce such impacts. Therefore, this paper presents an experimental study on the potential of granite dust as a filler in enhancing the mechanical performance of a hybrid basalt/glass (WB/GCSM) composite. The unhole and open hole tensile (UHT and OHT) properties, low velocity impact (LVI) properties, quasi-static indentations (QSI) properties, flexural properties, interlaminar shear stress (ILSS) properties, and morphology of the developed WB/GCSM composites were evaluated. To meet the objective of this study, composite specimens were produced using 1.5–60 μm granite fly dust at three (3) different loadings (1, 3 and 5 wt%). This granite fly dust was incorporated into polyurethane resin using a mechanical stirring technique. The production of FRP laminates then completed using a hand lay-up and vacuum bagging technique. Four types of the WB/GCSM composites systems, i.e., [WB/GCSM], [WB/GCSM/1GD], [WB/GCSM/3GD] and [WB/GCSM/5GD] were fabricated and compared. The analysis results for the mechanical tests revealed that the incorporation of granite dust of up to 3 wt% had increased the UHT, OHT, LVI, QSI, flexural and ILSS properties of all WB/GCSM composites systems. Higher levels of damage tolerance in UHT and OHT tests, and increased ductility index in the LVI test were obtained when granite dust was added up to 5 wt%. However, a remarkable improvement in all mechanical properties was noticed for [WB/GCSM/1GD], which recorded the highest mechanical performance among all WB/GCSM composite systems.

“…High-density polyethylene (HDPE), also called low-pressure polyethylene, has a highly regular molecular structure with high crystallinity, melting point and density and few and short branches in its molecules. [24] HDPE is commonly used in the manufacturing of container bottles and toys, based on high strength characteristics. At room temperature, HDPE is insoluble in any organic solvent and has high corrosion resistance to acids, bases and salts.…”

Waste plastics (e.g., polyethylene, polyvinyl chloride, polypropylene, polystyrene) and petroleum sludge (i.e., main residual from the petroleum industry) pose a severe threat to the environment and human health. These materials are basically nonbiodegradable, and it is difficult to realize the recycling of them and resources via traditional treatment methods. Catalytic pyrolysis as a new recycling treatment method has the characteristics of high efficiency, environmentally benign, no secondary pollution and high product utilization value. This paper mainly reviews the research progress of catalysts used in the catalytic pyrolysis of waste plastics and petroleum sludge. They include molecular sieves, transition metals, metal oxides, clays and activated carbons used for the recycling of plastic, and molecular sieves and M-series catalyst (M=Al, Fe, Ca, Na, K) for treating petroleum sludge. The mechanism of catalytic pyrolysis is also elucidated in this paper. In addition, the challenges faced by catalytic pyrolysis of waste polymers and the future development prospects are also presented.

In this study, soapstone waste originated from craftsmanship activities was used as an alternative filler (0–30 wt%) for a high‐density polyethylene (PE) matrix. The aim of this paper is to understand the effect of the filler particles on crystallinity, thermal stability and thermo‐mechanical properties of this newly developed composite material. Physico‐chemical characterization was performed by x‐ray diffraction (XRD) and Fourier‐transform infrared (FTIR) spectroscopy. Thermogravimetric analysis (TGA), oxidation induction time (OIT) and dynamic mechanical thermal analysis (DMA) were performed to assess the effect of the filler on the themo‐mechanical properties of PE. Thermal stability, measured by TGA, was enhanced, while OIT values reduced with filler content. A significant increase on the storage modulus of the composites (up to 148% in comparison with unfilled PE) was observed and this reinforcing effect was even more prominent at higher temperatures. XRD analysis revealed that the degree of crystallinity improved significantly with soapstone loading, which explains the substantial increase in stiffness observed. Increased crystallinity is also associated with higher strength, reduced residual stress, and better dimensional stability of end products, which can be particularly attractive for pressure pipe applications.
