“…7 On this basis, several technologies have been introduced to avoid these technical problems; one of these latest technologies is the microbial desalination cell (MDC) system, 8,9 which is a modified form of the microbial fuel system (MFC) and the bio-electrochemical system (BES) system. 10,11 MDC has exhibited a high efficiency in reducing pollution in wastewater, even with water containing less than 2000 mg L −1 of COD, by converting it into electrical energy. This system will help the processing and production of wastewater and electrical energy, respectively.…”

“…The effort of building water treatment plants powered by renewable energy aims not only to meet the global need for potable water but also to reduce the harmful gas emissions that affect humans and living organisms; the use of fossil fuels and combustion processes results in toxic gases, global warming, and climate change 7 .

Seawater might serve as a fresh-water supply for future generations to help meet the growing need for clean drinking water. Desalination and waste management using newer and more energy intensive processes are not viable options in the long term. Thus, an integrated and sustainable strategy is required to accomplish cost-effective desalination via wastewater treatment. A microbial desalination cell (MDC) is a new technology that can treat wastewater, desalinate saltwater, and produce green energy simultaneously. Bio-electrochemical oxidation of wastewater organics creates power using this method. Desalination and the creation of value-added by-products are expected because of this ionic movement. According to assessments, recent investigations on MDC configurations have led to significant changes in their operating characteristics, as well as their design and operational factors. Additionally, the study notes the expanding uses of MDC in bioremediation, nutrient recovery, water softening, and value-added chemical manufacturing. Significant results show that the MDC system produced outstanding desalination without the need for external power, in addition to achieving wastewater treatment and energy recovery without the need for intermediary processes. When it comes to its practical application, some of the technical obstacles include keeping pH stable in cathodic and anodic fluids, increasing internal resistance using catalysts as electrode fillers, along with issues of biofouling and durability. Although MDC technology is currently being developed and scaled up, additional research on membrane fouling avoidance, material feasibility, electron transport kinetics, growth of microorganisms, and catalyst durability is needed.

“…This differs from 38 the 42 and is also significantly influenced by the thickness of the blanket material forming the column and the strength of the surrounding soil (12). In theory, both are consistent with this (Barksdale and Bachus, 1983, Han and Ye 1991, Aslani and J. Nazariafshar 2021) (13)(14)(15). Some research and studies have turned to encase the stone column in geogrid or another high-tension material to counteract the weakness caused by a flaw in the soil around it.…”

The usage of stone columns is one of the best ways to accentuate the ground. minimize settlement and increase the soil's carrying capacity. In this study, stone columns with complete geogrid reinforcement built of recycled concrete aggregates were utilized. Soft clay soils have been strengthened in a variety of methods. The results indicated that the use of stone columns made of recycled concrete aggregates fully reinforced with geogrid resulted in a significant improvement in the BC of soils. Compared to natural soil, the use of stone and double columns reinforced with a geogrid network improved the BC of the soil by 9% with an increase in the percentage of improvement when using other patterns.

“…However, the main disposal methods for CSF are incineration, burial and composting. These methods do not provide economic benefits and burning releases dust particles and toxic and harmful gases that ultimately affect human health [ 18 ]. In addition, in terms of industrial application, CSF is still at the primary level of processing for simple use.…”

In recent years, under the pressure of resource shortage and white pollution, the development and utilization of biodegradable wood-plastic composites (WPC) has become one of the hot spots for scholars’ research. Here, corn straw fiber (CSF) was chosen to reinforce a poly(lactic acid) (PLA) matrix with a mass ratio of 3:7, and the CSF/PLA composites were obtained by melt mixing. The results showed that the mechanical properties of the corn straw fiber core (CSFC) and corn straw fiber skin (CSFS) loaded PLA composites were stronger than those of the CSFS/PLA composites when the particle size of CSF was low. The tensile strength and bending strength of CSFS/CSFC/PLA are 54.08 MPa and 87.24 MPa, respectively, and the elongation at break is 4.60%. After soaking for 8 hours, the water absorption of CSF/PLA composite reached saturation. When the particle size of CSF is above 80 mesh, the saturated water absorption of the material is kept below 7%, and CSF/PLA composite has good hydrophobicity, which is mainly related to the interfacial compatibility between PLA and CSF. By observing the microstructure of the cross section of the CSF/PLA composite, the research found that the smaller the particle size of CSF, the smoother the cross section of the composite and the more unified the dispersion of CSF in PLA. Therefore, exploring the composites formed by different components of CSF and PLA can not only expand the application range of PLA, but also enhance the application value of CSF in the field of composites.
