“…For the GSBE samples, the absorbance of COD and am-monia was measured using the HACH DR3900 spectrophotometer. The pH of the GSBE's original solution was adjusted using sodium hydroxide and sulfuric acid solutions [27]. Every measurement was performed three times, with the average results being presented.…”

The conventional disposal of green straws through burning can be eliminated in a biorefinery that converts them into a range of sustainable commercial products. However, this leads to the generation of green straw biorefinery effluent (GSBE). Green straw biorefineries discharge wastewater into the ecosystem that contains high concentrations of COD and NH4+−N. It is one of the most notable sources of visual pollution and disruption of aquatic life as well as public health that requires treatment prior to discharge. To improve the GSBE quality for environmental sustainability, the attainment of sustainable development goals 6, 9, and 14, “clean water and sanitation”, “inorganic and organic waste utilization for added values from material”, and “life below water” is very important. Therefore, the effectiveness of the continuous mode activated sludge (CMAS) system and the biocomposite-based–continuous mode activated sludge (SB-CMAS) system in the treatment of GSBE was investigated in this study. Response surface methodology (RSM) was used to optimize the process variables. At their optimized conditions, the performances of CMAS and SB-CMAS were analyzed in terms of COD and NH4+−N. Findings showed 81.21% and 95.50% COD and 78.31% and 87.34% NH4+−N reduction in concentration for CMAS and SB-CMAS, respectively. The high COD and NH4+−N removal efficiencies indicate the better performance of CMAS and SB-CMAS. The first- and second-order models and the modified Stover–Kincannon biokinetic models were utilized to analyze substrate removal rates. It was discovered that the modified Stover models were ideal for the measured data with R2 values 0.99646 and 0.91236 attained for COD and NH4+−N, respectively, in CMAS. The SB-CMAS had 0.99932 and 0.99533 for COD and NH4+−N, respectively. Maximum contaminant elimination was attained at 60% GSBE and 2-day HRT. Thus, to achieve the UN SDGs for 2030, findings from this study have the potential to answer goals 6, 9, and 14.

“…Common examples include lead, mercury, cadmium, arsenic, chromium, and nickel. Due to potential risks, heavy metal presence is closely monitored and regulated (Jagaba, et al, 2024). Heavy metals can harm the body by building up in cells and tissues, damaging important molecules like proteins and DNA.…”

This research looks at how the growth of cities and industries affects the levels of heavy metals in the soil, which can impact people's health. We find out where the pollution comes from, such as factories, car fumes, and improper waste disposal, by reviewing existing studies. We use different methods to test the soil for heavy metals and study how exposure to these metals in urban areas affects people's health. The evidence shows a connection between high levels of heavy metals in city soil and health problems like breathing issues, brain disorders, and overall toxicity in the body. We also explore how these metals get into the human body, highlighting the importance of understanding how they are available and the ways people are exposed. To deal with polluted city soils, we look at different ways to manage the soil and suggest sustainable methods to reduce heavy metal pollution. Our discoveries add to what we know about urban environmental health, emphasizing the need for actions to protect city residents. Ultimately, this study aims to give important information and insights to policymakers, city planners, and public health officials for managing and lessening the health risks linked to heavy metal contamination in urban soils.

“…The minimum thickness of lever arm of 12 mm will induce a maximum bending stress of 56 N/mm 2 , while crossing beams, transfer column and anchor legs will induce a maximum bending stress of 7N/mm 2 which is less than the bending stress of 220 N/mm 2 [22]. Hence the design is safe to carry the load of 500 kg [32]. The fulcrum pin diameter was designed to be 27 mm with a maximum induced shear stress of 4N/mm 2 .…”

The study is to design field-operated plate load test equipment to overcome the problem of predicting bearing capacity and settlement of clayey soil on site using the conventional/traditional methods of short-duration plate load test where a hydraulic jack is used in conducting the test. Ashby's method of material selection was used for the selection of a suitable material for each of the components. The 12 mm thickness was obtained as the minimum safe thickness for the applied load of 500 kg on the lever arm. The I-section frame that support the entire system has sectional modulus of 19.4 cm3 and 4 mm thickness. The equipment will use a lever arm mechanism to conduct an in-situ test that will take long-duration on clay soil where the dissipation of pore water from the clayey soils takes a longer time to complete as against the current conventional method of plate load test that is in use. The equipment will offer several advantages in terms of cost, reliability, portability, authenticity, and user friendly.
