“…This enhanced adsorption makes it effective at removing contaminants such as heavy metals, nitrates, and ammonia from water ( Dey et al, 2021 ; Mahato et al, 2021 ). We have assessed the adsorption of copper ( Figure 2A ), as well as nitrates ( Figure 2B ) and nitrites ( Figure 2C ) on unprocessed and HC-processed peel, with biosorption parameters reflecting favourable binding ( Supplementary Tables S1, S2 ) in harmony with previous works ( Feng et al, 2009 ; Izquierdo et al, 2013 ; Abdulrazak, 2016 ; Romero-Cano et al, 2016 ; Amin et al, 2017 ; Surovka and Pertile, 2017 ; Özkan et al, 2017 ; Amin et al, 2019 ; Safari et al, 2019 ; Kumar and Raju, 2020 ; Amirsadat et al, 2022 ; Shahaji et al, 2023 ). Though further HC-treatment and pH optimisations are required to maximise copper and nitrate binding, these preliminary works demonstrate that HC pre-treatments even under suboptimal pH can provide a level of physical peel modification essential for the adsorption of the tested chemicals.…”

Introduction: The endorsement of circular economy, zero-waste, and sustainable development by the EU and UN has promoted non-thermal technologies in agro-food and health industries. While northern European countries rapidly integrate these technologies, their implementation in Mediterranean food-supply chains remains uncertain.Aims: We evaluated the usefulness of hydrodynamic cavitation (HC) for valorizing orange peel waste in the fresh orange juice supply chain of the Maltese Islands.Method: We assessed: a) the effectiveness of HC in extracting bioactive compounds from orange peels (Citrus sinensis) in water (35°C) and 70% (v/v) ethanol (−10°C) over time, compared to conventional maceration, and b) the potato sprouting-suppression and biosorbent potential of the processed peel for copper, nitrate, and nitrite binding.Results: Prolonged HC-assisted extractions in water (high cavitation numbers), damaged and/or oxidized bioactive compounds, with flavonoids and ascorbic acid being more sensitive, whereas cold ethanolic extractions preserved the compounds involved in radical scavenging. HC-processing adequately modified the peel, enabling its use as a potato suppressant and biosorbent for copper, nitrate, and nitrite.Conclusion: Coupling HC-assisted bioactive compound extractions with using leftover peel for potato-sprouting prevention and as biosorbent for water pollutant removal offers a straightforward approach to promoting circular economic practices and sustainable agriculture in Malta.

“…It might contain proteins and polyphenols at certain level. The functional groups of these agricultural by-products such as alcohols, aldehydes, ketones, carboxylic, phenolic and ether groups have ability to bind heavy metals by donation of an electron pair from these groups to form complexes with metal ions in aqueous solution (Shakoor & Nasar 2016;Khan et al 2017;Vilardi et al 2018;Astuti et al 2019;Masoudian et al 2019;Meseldzija et al 2019;Safari et al 2019;Shakya & Agarwal 2019;Yusuf et al 2020). The interaction of the functional groups presents on the surface of the biosorbents deteriorate lignocellulosic structure of the fruit rinds.…”

In this study, six fruit rind, chemical activated using ZnCl2 and carbonized by microwave, were used as biosorbent to remove zinc from aqueous solution. Fruit kind, microwave treatment time and adsorption contact time effects on zinc biosorption yield were examined. The characterization of raw materials and synthesized biosorbents were realized by Fourier-transform infrared spectroscopy (FT-IR). The dried fruits rinds were activated for 2 or 4 h using ZnCl2 and carbonized for 1, 2, 3 or 4 min at 800 W microwave power. Zinc biosorption yield was determined using ultraviolet-visible spectroscopy (UV-Vis). Maximum zinc biosorption capability was determined 39.18 mg/g for lemon, 35.78 mg/g for orange, 14.76 mg/g for watermelon, 13.06 mg/g for melon, 12.2 mg/g for pineapple and 9 mg/g for banana rinds. The results indicate that the six fruits rinds can be used for zinc adsorption from aqueous solution as cost-effective and environmentally friendly biosorbent with high adsorption efficiency.

“…On the basis of previous research, activated carbon from banana peel waste has the potential to become an adsorbent material. Activated carbon as an adsorbent material has a large surface area, quite large pores and is hydrophobic (does not mix with water), can eliminate odors and cloudy colors in polluted water (Safari et al, 2019;. Although activated carbon from banana peel waste is a material that is quite potential for adsorption of heavy metal ions, but as an adsorbent material it has several weaknesses, including being difficult to separate in the adsorption process and it cannot be used repeatedly, so modifications are needed with the development of other technologies to assist the separation, namely magnetic technology (Siregar et al, 2021;Yu et al, 2021).…”

The development of nanoadsorbents for remediation of polluted water in order to obtain clean and healthy water quality has been carried out, namely the incorporation of chitosan, magnetic, and activated carbon materials. The activated carbon used is the result of the synthesis of banana peel waste nanocrystals, while the magnetic is Fe 3 O 4 . The method used in this study is an experimental method with coprecipitation through several stages, namely (1) magnetic synthesis of Fe 3 O 4 by thecoprecipitation method, (2) preparation of chitosan solution, (3) synthesis of activated carbon nanocrystals from banana peel waste by the milling process, (4) merger of the three materials, and (5) characterization with SEM/EDX, XRD, FTIR, BET, PSA, TGA, and AAS to test the performance of the material against polluted water. The study found that 210 minutes was the optimal time for the heavy metal ions Fe, Mn, Zn, and Pb to adsorption.The best sample was sample S4 with a ratio of 1:2:2 with adsorption for Zn 92.43%, Fe 95.44%, Mn 89.54%, and Pb 84.38%. For the heavy metal ions: Mn 5624 mg/g, Fe 5849.4 mg/g, Zn 4894.22 mg/g, and Pb 468.2 mg/g, the Langmuir model was used. The adsorption kinetics showed that the reaction order for Pb, Mn, Zn, and Fe ions varied with pseudo-first order and pseudo-second order. Carboxymethyl cellulose nanoadsorbents are effective in remediating the water contaminated with heavy metals, such as Pb, Mn, Zn, and Fe, meeting the environmental health quality standards for water media for sanitation hygiene purposes.
