“…Besides, the low bioavailability of the PTEs in the targeted area has also limited the full potential and capability of phytoremediation (Guo et al, 2021;Khalid et al, 2017;Lu et al, 2020;Wang et al, 2019;Zhu et al, 2020). The PTEs must be available within the range of the plant's root system and phytoavailable forms for the absorption process to take place (Schwitzguebel, 2017;Tripathi et al, 2020). Moreover, the depth of treatment to the root zone and shorter root system were also reported as a limitation for the traditional phytoremediation method as the shorter root system often affects the effectiveness of the process (Capuana, 2011;Thakur et al, 2016;Tiodar et al, 2021;Shen et al, 2022).…”

“…Phytoremediation, a bio-technology that uses plants and their rhizospheric microorganisms to stabilize and degrade various pollutants from the environment, is considered as a preferred remediation technique [133,134]. Decades ago, plants were recognized for their ability to absorb unwanted and toxic chemicals, leading to a growing interest in the phytoremediation of heavy metals [135][136][137], organic pollutants [138,139], and recently, MPs [140,141]. Advantages of phytoremediation include economic feasibility, environmental friendliness, adaptability, and large scale application [142,143].…”

The occurrence of microplastics (MPs) and their omnipresence have attracted enormous attention across the globe; however, research on MPs in South Africa is still in its infancy and thus, the data are still very much lacking. Approximately 120 million tons of general waste is generated each year in South Africa, which exacerbates the pressure on the ability of municipalities to manage waste. Wastewater treatment plants (WWTPs) are at the center of this general waste that includes plastic debris and primary MPs that are discharged from households and industries. In general, the removal efficiency of MPs across the globe was found to be between 70% and 99%, with biological treatment technology common in both primary and secondary treatment steps in WWTPs. Furthermore, the current review paper has revealed that there is a wide research gap on the occurrence and fate of MPs in WWTPs across South Africa. This is a worrying factor considering the increasing rate of plastic waste generation due to rapid industrialization, urbanization, and overpopulation in the country. More so, the scarcity of data regarding the occurrence of MPs in freshwater is widely noticeable across the country. Therefore, given the amounts of MPs discharged from households, industries, and plastic debris littered into the surface waters, the data on the occurrence and fate of MPs in South Africa should be given the urgent attention they deserve. To achieve the effective and sustainable management of water resources and services set out in the National Development Plan (NDP) 2030 adopted by the government, the status and capabilities of WWTPs to remove MPs must be monitored and addressed. In addition to achieving the zero waste to landfill goal by 2030, a circular economy is regarded as the most effective model for solving the plastic waste crisis in the environment; therefore, its full implementation is required for a substantial impact.

“…Environmental remediation using photocatalysis for degradation of toxic pollutants from waste water have been studied intensively. The effect of many aspects, including catalyst concentration, pollutant concentration, solution pH, and radiation time on the kinetics (Silva et al, 2022) (Krstić et al, 2021), adsorption isotherm (Foo et al, 2010)and thermodynamics (Tripathi et al, 2019) (Elfeky et al, 2020) of pollutant degradation have been investigated. The photodegradation is a positive development to reduce waste and minimize environmental pollution (Cui et al, 2020).The situation will help to improve wastewater management at minimal cost for the highest quality of water (Anjum et al, 2019).…”

Green magnetite nanoparticles (NPs) are synthesized, characterized and employed for degradation Methylene Blue (MB) from aqueous solutions. The effect of the concentrations of the NPs and MB on NPs yield and removal efficiency is optimized and modeled using two factorial central composite experimental design. The analysis of variance confirmed that the concentration of iron metal salts seemed more significant than plant extract. The developed mathematical model is estimated with high R2 reflecting its accuracy. The results proved that the removal efficiency of MB increases up to an optimum of 82.07 % when using 0.17 g of the nano photo catalyst versus 10.8 ppm of MB with sunlight irradiation time of 200 min. The dye degradation kinetic results revealed that photo catalytic degradation follow pseudo-first-order model. Response Surface Methodology proved as an efficient tool for optimization and modeling the processes of NPs production and removing of organic pollutants from aqueous solutions.
