“…Subsequently, the porosity of 0.2 ratios produced the lowest density among others. When WW was added, density decreased, but porosity increased, exhibiting large holes comparable to those found in the compositions using RH in micrographs [36]. This is further corroborated by earlier research, which found that in addition to having a lower density than the matrix materials, fiber aggregation and cavities caused by the lack of matrix impregnation to the fibers were the contributing factors.…”

Commercial products made of plastics or wood have always been in high demand until now. Consequently, waste from these products has increased, accumulated, and catastrophically impacted the environment. Through recycling, waste products are not only reduced but will also be easily available for improvement or manufacturing new products. This research focused on the fabrication of lightweight composites using plastic waste (PW) and wood waste (WW) as reinforcement and epoxy as a matrix suitable for tile applications. It was revealed that the density of PW-WW polymer composite increased with increasing PW loading up to a 4.0 ratio at 1.070 g/cm3 with a porosity of 0.05%. Optical microscope analysis at 100X magnification showed good bonding between the reinforcements (PW and WW) and matrix (epoxy). With a maximum bending strain of 2.41%, the 3.0 ratio achieved the highest bending strength of 2069.20 N, followed by the bending stress at 8.28 MPa. The PW-WW polymer composite with a composition ratio of 3.0 showed a maximum tensile force of 313.8 N and a tensile strength of 1.79 MPa. The composite with a 4.0 ratio had the greatest impact strength (1.67 kJ/m²), followed by the composite with a 3.0 ratio (1.44 kJ/m²). In summary, a 3.0 ratio is the best polymer composite composition for tile applications.

“…In urban management, it has been reported that rice husk nanoparticle composites effectively mitigate the reverberation effect around building facades caused by noise. The composite generated tends to have a high absorption material that is denoted by increasing the sound absorption coefficient of materials (Rendón et al, 2023;Sharma et al 2023;Raj et al, 2020;Hassan et al, 2020;Echeverria et al 2019;Samodra, 2018). They observed that the relation between the particle size of the filler and sound absorption coefficient levels was affected.…”

Transportation tracks of railways and highways are the highest noise pollution contribution to the inhabitant urban due to the sources near residential areas. Many researchers proved that the composite material could help reduce the noise by 30%. This study focuses on designing local nature fiber composite for developing a good sound absorption material by providing experimental methods. Three natural fibers of coconut, palm oil, and sugarcane are used to make a composite by varying filler content for sound absorption and transmission loss observation. The results found that sugar cane bagasse is suitable for average performance in varied filler content for both sound absorption and transmission loss. The overall results showed a successful improvement in both sound absorption coefficient and transmission loss with the addition of fiber content.

“…As the combustion temperature increases, the K+ cation will reduce the crystallization temperature of the silica, causing it to merge with surrounding particles, thus forming larger particle aggregates [12]. Evidently, the pre-combustion removal of most metal cations from nano-silicon dioxide profoundly influences its purity and particle size [13,14].…”

The rice husk (RH) combustion pretreatment method plays a crucial role in the extraction of nanoscale SiO2 from RH as a silicon source. This study examined the effects of diverse pretreatment methods and combustion temperatures on the particle size distribution of nanoscale high-purity amorphous SiO2 extracted from rice husk ash (RHA) post RH combustion. The experiment was structured using the Taguchi method, employing an L9 (21 × 33) orthogonal mixing table. The median diameter (D50) served as the output response parameter, with the drying method (A), combustion temperature (B), torrefaction temperature (C), and pretreatment method (D) as the input parameters. The results showed the torrefaction temperature (C) as being the predominant factor affecting the D50, which decreased with an increasing torrefaction temperature (C). The optimal parameter combination was identified as A2B2C3D2. The verification test revealed that roasting could improve the abrasiveness of Rh-based silica and reduce the average particle size. Torrefaction at medium temperatures might narrow the size distribution range of RHA-SiO2. We discovered that the purity of silica increased with an increasing roasting temperature by evaluating the concentration of silica in the sample. The production of RHA with silica concentrations up to 92.3% was investigated. X-ray diffraction analysis affirmed that SiO2’s crystal structure remained unaltered across different treatment methods, consistently presenting as amorphous. These results provide a reference for extracting high-value products through RH combustion.
