“…The slump test was carried out in accordance with ASTM C143-15 [31]. Physical parameters of cementitious, physical characteristics, have examined using a 1500 kN capacity external characteristics instrument in Figure 3 [39,40]. After the compression test was conducted, which involves loading the test specimen between two plates and applying pressure to it by moving the graphical illustrations together, the 28-day curing process was completed.…”

<p>In concrete industry, the use of concrete solid wastes is becoming further common since it can minimize associated costs and environmental implications. The current research looks at how concrete performs when polypropylene (PP) plastic, produced from pollution garbage items, is used as a partially replacing for coarse aggregate (CA). The proportion of total PP (PPA) (0, 5, 10, 15, and 20%) as well as the water-cement ratio 0.45 of recycled household waste water, are the most important variables. Flow ability, hard porosity, maximum compressive strengths are all factors to consider, and economic feasibility are all discussed. The slump value grew when the proportion of PPA was raised, according to the findings. Compressive and cracking tensile strengths were increased in concrete containing 15% PPA. As a result, suggested to utilize more than 10% PPA in structural concrete, with either crushed stone or PP aggregate. The results showed that 15% is the best alternative to coarse gravel during terms of strength and durability, and hence PPA can be utilized as a partial replacement for coarse aggregate in concrete. To conduct studies to enhance the impact resistance of concrete by utilizing recycled water. Reducing the consumption of nonrenewable resources reducing greenhouse gas emissions and improving the strength and load capacity of industrial materials used in building research. Finally, employing non-biodegradable waste plastic resources to make green concrete will offer up new possibilities.</p>

“…The base area of the still is 0.36 m 2 (0:6 m length × 0:6 m breadth). The taller side wall has a 2 International Journal of Photoenergy height of 0.5 m and the shorter side wall has 0.2 m. To increase the absorptive, black paint has been applied to the basin's interior surface [24][25][26]. The basin is protected with glass which allows the solar radiation to reach the basin plate and also acts as the condensing surface.…”

This research work explored and compared the experimental performance of a solar still having novel octagonal-pyramid shape with a single slope solar still. It is found that the novel still provides twice distillation compared with conventional still. The experiments also evaluated the desalination productivity of octagonal-pyramid solar still by varying the depth of saline water inside the basin and angle of inclination of glass cover. It is observed that the optimum condition for high distillation is obtained when depth of water inside the basin is 5 cm with angle of inclination of glass cover which is 30°. Four types of water, i.e., underground borewell water, sea water, leather industry effluent, and plastic industry effluent were also used to see the effect on distillation. Results showed that underground borewell water provides high distillation due to low density. Furthermore, the performance of the octagonal-pyramid solar still is enhanced by adding different latent heat and sensible heat materials in the octagonal-pyramid solar still. Hence, the addition of brick to the octagonal-pyramid still yields the highest productivity compared to incorporation of paraffin wax. Hence, it can be concluded that the octagonal design of the solar still has shown an increased productivity when compared to a single slope solar still (conventional still) under all the conditions.

“…The increased FFA content of Mahua oil was reduced by two-step processing method. Experiments in both phases were conducted with a catalyst that had a contained 1% v/v H2SO4 and a molar ratio of 0.35-0.40 v/v methanol to oil (Mohanraj et al, 2022;Vinayagar et al, 2022;Krishnaraja et al, 2022;Yamunadevi et al, 2021). The process was carried out at a temperature of 60 ± 1 °C for 60 minutes.…”

<p>A feasible alternative fuel for diesel engines in recent days is biodiesel, which can be produced from both edible and inedible feedstock. When considering the economic and environmental aspects, there is a considerable academic interest among researchers in the transesterification of non-edible oils to yield valuable Biodiesel, as compared to biodiesel production from edible oils. Prosopis juliflora oil was extracted using the solvent extraction technique. By using a two-step acid esterification method, the FFA acid value was reduced less than 1%. The acid value underwent a two-step reduction, initially decreasing from 44 KOH/gm to 8.6 mg KOH/gm, and subsequently reaching 2.7 mg KOH/gm. The implementation of the above procedure can effectively mitigate significant problems in diesel engines when using high viscous non-edible oils. The primary objectives of this research were to maximize the biodiesel output and simultaneously minimize the acid value. Response Surface Methodology (RSM) was employed in the current investigation to optimize different parameters. D-optimal design technique in Response Surface Methodology (RSM), was used for analyzing the methanol/oil volume ratio (factor A), reaction temperature (factor B), and reaction time (factor C) as process variables. The focus of the analysis was on the percentage of acid value (Y).</p>
