“…65 This type of waste is mostly peels, seeds and pits, which are rich in nutrients and compounds with high added value such as pigments, polyphenols, flavonoids, and essential oil. 66 For example, mango seeds contain about 10% protein, 2.4% fiber and 70% carbohydrate, and have high antioxidant capacity. 67 Grape seed extract, which is rich in proanthocyanins, has been attributed in scientific articles with high antioxidant potential (ability to neutralize free radicals), antithrombotic, antitumor, antimutagenic, and anti-fatigue effects, which have been associated with reducing the incidence of some diseases such as myocardial infarction, myocardial infarction, and atherosclerosis.…”

“…Reduction, repair, remanufacturing, and recycling are normally acknowledged as the representative loops of the circular economy [2]. Some authors refer to these as holistic approaches to add value to biowastes from fruit and vegetable processing [3], of which aromatic plants represent a small percentage. The goal of adding value and reducing waste to zero may invoke participation not only in physical processes related to extraction but also in chemical transformations (hydrolysis), fermentations, and bioprocessing with microorganisms.…”

Essential Oils - Recent Advances, New Perspectives and Applications

The average annual trade of over 250 thousand tons of essential oils generates over 250 million tons of distillation residues, posing environmental problems due to incineration or landfill overburden. The circular economy focuses on reducing resource inputs, waste generation, and pollution, for sustainability. Implementing circular economy principles not only mitigates environmental concerns but also creates economic opportunities by utilizing residual biomass. Nonvolatile secondary metabolites, like flavonoids and phenolic compounds, remain in plant material during essential oil distillation. These bioactive substances can be extracted from the biomass distillation residues. Instead of discarding or burning waste from essential oil production, it can be processed to make extracts. The residue can be converted into biochar, a carbon-rich material beneficial for soil improvement. Other end uses include generating combustible bio-oil and using distillation residues for mushroom cultivation. Circular economy practices in the essential oil agroindustry have implications beyond the field itself. By providing raw materials for various sectors and industries, such as agriculture, cosmetics, and pharmaceuticals, this agroindustry can contribute to broader sustainability goals. While the adoption of circular economy principles presents technological challenges, the potential benefits in terms of waste reduction, value addition, and sustainability justify ongoing research and development efforts.

“…These plant phytoconstituents act as capping agents and natural bio-reductants of metal/metal oxide ions, thereby sterically stabilizing nanomaterials by reduction through direct molecular interaction [ 5 ]. Scientific analysis has shown that large volumes of bio-wastes produced from fruit and vegetable peels, which are a rich source of several biocomponents, are neglected, ultimately putting market vendors in risky circumstances [ 6 ]. A feasible approach of reducing bio-waste can be established through its application in the production of advantageous nanomaterials [ 7 ].…”

Background. Magnesium oxide nanoparticles (MgONPs) have been fabricated by several approaches, including green chemistry approach due to diverse application and versatile features. Objectives. The current study aimed to prepare a convenient, biocompatible, and economically viable MgONPs using waste citron peel extract (CP‐MgONPs) to evaluate their biological applications. Methods. The CP‐MgONPs were synthesized by a sustainable approach from extract of waste citron peel both as capping and reducing agents without use of any hazardous material. The physicochemical features of formed CP‐MgONPs were determined by sophisticated analytical and microscopic techniques. The biogenic CP‐MgONPs were examined for their antibacterial, anticarcinogenic, and photocatalytic attributes. Results. A prominent absorption peak in the UV‐Vis spectra at 284 nm was the distinguishing characteristic of the CP‐MgONPs. The scanning electron microscopy (SEM) reveals polyhedral morphology of nanoparticles with slight agglomeration of CP‐MgONPs. The CP‐MgONPs exerted excellent antibacterial potencies against six bacterial strains. The CP‐MgONPs displayed significant susceptibility towards E. coli (20.72 ± 0.33 mm) and S. aureus (19.52 ± 0.05 mm) with the highest inhibition zones. The anticancer effect of CP‐MgONPs was evaluated against HepG2 (IC50 : 15.3 μg·mL−1) cancer cells and exhibited potential anticancer activity. A prompt inversion of cellular injury manifested as impairment of the integrity of the cell membrane, apoptosis, and oxidative stress was observed in treated cells with CP‐MgONPs. The biosynthesized CP‐MgONPs also conducted successful photocatalytic potential as much as MgO powder under the UV‐light using acid orange 8 (AO‐8) dye. The degradation performance of CP‐MgONPs showed over 94% photocatalytic degradation efficiency of acid orange 8 (AO‐8) dyes within a short time. Conclusions. Outcomes of this research signify that biogenic CP‐MgONPs may be advantageous at low concentrations, with positive environmental impacts.
