“…Although the removal percentage reached its ultimate value, 4 was considered to be the optimal value of the acidity function for the adsorption of copper ions. Both [21,38] indicated results similar to the acidity function set results obtained in this study.…”

“…However, the high cost of these media and the loss of some of their mass in each regeneration step prompted researchers to use alternative materials of appropriate efficiency, available, cheap, and at the same time, without toxicity [20]. Among these materials that meet the above conditions are agricultural wastes [21]. Agricultural residues are available in large quantities throughout the year as a result of the human consumption of agricultural crops and can be utilize by different methods, such as producing beneficial chemicals [22], fertilizers [23], and [24], and addition of material to concrete [25] and synthesis of nano-materials [16] because of its unique properties, either naturally or gained after treatment [26].…”

The possibility of recovering one of the famous heavy metal ions, divalent copper, from contaminated aqueous solutions (which simulates wastewater) was studied in this study. The removal method was adsorption technique using a laboratory batch-mode unit, while the used tea leaves were the adsorption media. The adsorption process was performed under various operating conditions and ranges that simulate the natural environmental conditions to determine the ideal values that achieve the maximum removal of copper ions. The acquired results demonstrated that the maximum remediation efficiency was 85%, which was achieved at treatment time, shaking speed, initial concentration, temperature, acid function, and adsorption dose of 90 min, 250 rpm, 70 ppm, 25°C, 4, 4.5 g, respectively. The values of the thermodynamic properties demonstrated that adsorption is spontaneous, exothermic and has negative entropy, while adsorption follows Langmuir’s model and the second pseudo-model according to the isotherm and kinetic studies, respectively. To conduct the Zero Residues Level concept, the loaded used tea leaves were prepared to study it effect as a simple type of rodenticide by applying it to Sprague Dawley rats. The results of the test show that the effectiveness of utilizing the residues as rodenticide and the LD50 of the proposed rodenticide were identical to those mentioned in the literature. Based on these results, the current study sheds light on the possibility of converting used tea leaves from harmful solid waste to an environmentally friendly substance using it as an effective adsorbent medium for the treatment of water polluted with heavy metals.

“…More recently, CA has been used to alleviate yield loss in rice [36] and determine the potential acidity of tropical soils [37]. For other applications, CA has been used as starting reagent to return to common compounds such as nano CaO [38] and CaCO 3 [39] and prepare other compounds such as calcium phosphates [40], acetone [41], composite ceramic compounds [42], anhydrite calcium sulfate nanowhiskers [43], and cement mortar [44].…”

The search for sustainable resources remains a subject of global interest. Calcium acetate used in many fields was prepared using waste scallop shell as a raw material, and its physicochemical properties were investigated. The waste scallop shells were transformed to calcium acetate compounds by reactions with four acetic acid concentrations at ambient temperature until the completely dried powder is obtained. The maximum yield of 87% with short reaction time at a low temperature was observed in the reaction of 60%w/w acetic acid with scallop shells. Thermal transformation reactions of all prepared calcium acetate samples revealed temperature conditions for heating to produce other advanced materials. FTIR and XRD results confirmed the purity and solid phase of all prepared calcium acetate samples, and they were compared with those of literatures and found to be well consistent. The obtained timber-like particles have different sizes depending on the acetic acid concentration. This work reports an easy and low-cost method with no environmental effect to produce cheap calcium products to be used in the industry.

“…In addition to dichromate oxidation, an enzyme oxidation approach uses alcohol dehydrogenase. GC is the most often utilized approach since it provides results more expediently [33]. Dichromate oxidation is the simplest and most appropriate approach for determining ethanol concentration for research applications, such as choosing a high-yielding strain, designing bio-ethanol manufacturing techniques, monitoring processes and managing alcoholic drinks, and measuring the ethanol concentration in clinical samples; this technique determines the amount of ethanol solvent removed from the fermentation medium in this procedure.…”

The importance of this research lies in keeping pace with the global trend to diversify energy sources and reduce climate change and air pollution by shedding light on how to benefit from agricultural waste by using it as a raw material for the production of bioethanol, which is one of the most important types of renewable fuels. This review highlighted the; ways of converting agricultural and fruit waste into bioethanol and its environmental and economic benefits-including adding it to gasoline used as car fuel in different proportions, as it works to raise the octane number of gasoline and improve its quality, thus reducing its production costs and reducing gas emissions from vehicle exhaust. In addition, the global production of bio-ethanol was reviewed and is expected to reach it by the end of 2023. It also highlighted the results of several studies that dealt with the properties and uses of ethanol and the best agricultural wastes used for this purpose. It is suggested to focus on the agricultural waste in Iraq, such as rice husks, in terms of cost and conditions for improvement to increase bio-ethanol production using fermentation processes.
