“…It was reported that the incorporation of FA particles in PU foam dramatically increased the fire resistance and thermal stability of the composite foams. Choew et al [21] reported the usage of PU foam/FA blends as a commercial product to encapsulate heavy metals. It was observed that PU foam-FA blends were waterproof, with good resistance to heat and light.…”

Fly ash particles are usually spherical and based on their chemical composition; they are categorized into two classes: C and F. This study compares the microstructural, mechanical and thermal properties of extruded rigid PVC foam composites reinforced with class C and class F fly ash. The mechanical properties: such as tensile and flexural strength of composites containing class C fly ash were superior to the composites containing class F fly ash particles. Composites containing 6 phr class C fly ash showed a 24% improvement in the tensile strength in comparison to a mere 0.5% increase in composites reinforced with class F fly ash. Similarly, the addition of 6 phr of class F fly ash to the PVC foam matrix resulted in a 5.74% decrease in the flexural strength, while incorporating the same amount of class C fly ash led to a 95% increase in flexural strength. The impact strength of the composites decreased as the amount of either type of fly ash increased in the composites indicating that fly ash particles improve the rigidity of the PVC foam composites. No significant changes were observed in the thermal properties of the composites containing either type of fly ash particles. However, the thermo-mechanical properties measured by DMA indicated a steep increase in the viscoelastic properties of composites reinforced with class C flyash. The microstructural properties studied by Scanning Electron Microscopy (SEM) confirmed that fly ash particles were mechanically interlocked in the PVC matrix with good interfacial interaction with the matrix. However, particle agglomeration and debonding was observed in composites reinforced with higher amounts of fly ash.

Aim of study: The use of composites obtained from wood and similar lignocellulosic plants has increased all over the world. Because of the rapid depletion of forest natural resources, the rational use of declining wood raw materials and to evaluate environmental alternatives has gained importance. For this purpose, many alternative lignocellulosic raw materials are used as heat insulation material by producing foams. Material and method: This research compared the properties of liquefied using cotton burr after liquefaction under different acid concentrations, PEG 400-Glycerin/Cotton burr ratios, pore sizes, and PEG 400/Glycerin ratios. The cotton burrs were put in a reaction chamber at 160 °C for 2 h with the PEG 400-Glycerin/cotton burr and sulfuric acid in a glass balloon. Main results: The maximum yield in the liquefaction of cotton burrs was found in the polyethylene glycol/glycerin ratio of 1:1. It has been found that the amount of unliquefied cotton burrs decreased with increasing of the acid concentration, reaction temperature and time. Research highlights: Consequently, the liquefaction of cotton burrs could be seamlessly used in the production of polyurethane-type foam.

“…In recent decades, the reuse and recycling of industrial solid wastes and municipal solid wastes have attracted substantial interest in Taiwan (Chiang et al, 2010;Chow et al, 2008;Ghosh and Ghosh, 2013;Lin et al, 2009Lin et al, , 2011Popovici et al, 2013). According to Taiwan's Environmental Production Administration (EPA), 0.75 million tons of garbage was disposed in 2006, 5.84% of which was waste glass (Lin, 2007).…”

This study examined the characteristics of geopolymer with solar panel waste glass. After 28 days of curing, the compressive strengths of the geopolymer samples containing 10 mass % and 20 mass % solar panel waste glass were 63.3± 1.8 and 49.1 ± 2.2 MPa, respectively. The geopolymer sample with 10% solar panel waste glass exhibited a stronger reaction than that with 20% solar panel waste glass, and the strength decreased as the amount of solar panel waste glass increased. Thermo-gravimetric and differential thermal analysis (TG/DTA) results showed that the mass loss of geopolymer after heating declined as the amount of solar panel waste glass increased. The principal peaks in the Fourier transformation infrared spectroscopy (FTIR) spectra correspond to the Si-O-Al bond in geopolymer. Scanning electron microscopy (SEM) observations indicated that the microstructures of the stronger samples were more homogeneous, and the microstructures of geopolymer with 10% solar panel waste glass did not exhibit substantial deterioration. The experimental results indicate that solar panel waste glass has the potential to serve as a partial replacement of metakaolinite and exhibits favorable mechanic characteristics.
