“…Methods applied for extracting quinones include maceration [116], reflux [117], Soxhlet [118,119], microwave assisted [118,120,121], ultrasonic assisted [118,122], ultrasonic-microwave assisted [123], enzyme assisted [37,124], supercritical fluid [125], sublimation assisted [38], and pressurised liquid [121,126] extractions. The applicability, requirements and results vary considerably among these methods.…”

Synthetic dyes are by far the most widely applied colourants in industry. However, environmental and sustainability considerations have led to an increasing efforts to substitute them with safer and more sustainable equivalents. One promising class of alternatives is the natural quinones; these are class of cyclic organic compounds characterized by a saturated (C6) ring that contains two oxygen atoms that are bonded to carbonyls and have sufficient conjugation to show color. Therefore, this study looks at the potential of isolating and applying quinone dye molecules from a sustainable source as a possible replacement for synthetic dyes. It presents an in-depth description of the three main classes of quinoid compounds in terms of their structure, occurrence biogenesis and toxicology. Extraction and purification strategies, as well as analytical methods, are then discussed. Finally, current dyeing applications are summarised. The literature review shows that natural quinone dye compounds are ubiquitous, albeit in moderate quantities, but all have a possibility of enhanced production. They also display better dyeability, stability, brightness and fastness compared to other alternative natural dyes, such as anthocyanins and carotenoids. Furthermore, they are safer for the environment than are many synthetic counterparts. Their extraction, purification and analysis are simple and fast, making them potential substitutes for their synthetic equivalents. Graphic Abstract

“…Well, practically, this cannot be achieved, but it is always good to have a lofty target to pursue. Soybean protein meal (Glycine max) has been found to yield antimicrobial and antitumoral peptides [121], while antioxidative anthraquinones can be extracted from the roots of Morinda citrifolia, a plant belonging to the coffee family [168], and waste peels of the Juçara fruit have been found to be rich in phenolic compounds [29]. Hydrothermal treatment which is known to enhance enzymatic cellulose degradation [344] has been carried out on several other undervalued waste streams like olive prunes and peanut shells, indicating a swathe of potential side streams to be harnessed in a circular bio-economy knitting the agro-food sector with the chemical-pharmafood sector.…”

While ‘renewable’ is the keyword in a bioeconomy and resource conservation is the motivation behind a circular economy, a circular bioeconomy is one in which waste streams from renewable bio-resources are looped back into the technosphere—open-loop or closed-loop recycling or conversion from matter to energy. This systematic review brings together 385 publications from 2015 to 2021, originating from 50 countries and appearing in 150 journals, into a coherent account of the status quo of published research on circular bioeconomy. The numbers bear testimony to the growing interest in this field of research. Germany is the leading contributor to the scientific literature base (10%), while the Journal of Cleaner Production (9%) tops the list of journals in the fray. The methodology adopted has been clearly explained, and the discussion has been segmented into sub-sections and sub-sub-sections to do justice to the diversity of the nature of the publications. A little flexibility in organisation of the flow of the text has been availed of, to improve readability. The circular bioeconomy can be visualised as a set of ‘many through many to many’ relationships, enabling both economies of scale and scope in the longer run. This calls for extensive collaboration and cooperation among the numerous stakeholders involved. Several barriers will have to be overcome. Technology impact assessments and sustainability risk appraisals need to be carried out in order to ensure and convince stakeholders that they are on the right path. But as one knows and will appreciate, challenges lurk where there exist opportunities to be availed of, to replace the take-make-use-dispose paradigm of a linear economy to the grow-make-use-restore alternative.

The vegetable oils are obtained from the oilseeds and also from other oil bearing parts of plants like fruits (mesocarp and/or stones), tubers, germs, sprouts, and so on. A host of methods are employed to obtain the oil from different matrices and each method has its own set of advantages and disadvantages. The traditional methods of oil extraction are exhaustive and have low efficacy, while conventional method of mechanical pressing is simple and involves low cost but considered as an inefficient method because of low oil recovery when compared with chemical extraction methods. Due to higher oil recovery and economic gains, chemical methods of oil extraction are preferred globally; however, the chemical solvents used exhibited detrimental effect on the environment, oil quality, and human health, which impelled the development of new technologies. New advanced eco‐friendly techniques namely, enzyme‐assisted extraction, microwave‐assisted extraction, ultrasound‐assisted extraction, and supercritical fluid extraction can easily overcome the shortcomings of the conventional methods and holds the potential to meet the ever‐increasing demand of edible oils. Practical applications Limited land availability and growing demands for vegetable oils call for the development of improved cultivars for harnessing higher yields as well as more efficient oil extraction technologies to augment oil recovery from different oilseed crops without compromising with the oil quality. Widely practiced traditional and conventional methods of extraction have various disadvantages namely, use of solvents, protractive protocols, and have adverse effects on environment, oil quality, and human health. Therefore, in order to overcome the demerits associated with the existing methods, green extraction technologies have been developed as an alternative, which offer various advantages like less extraction time, high extraction yields, and quality and minimized solvent consumption. The information compiled in this review on various extraction technologies will help oilseed processors and researchers in choosing the most appropriate method of oil extraction in order to achieve high yields without compromising the inherent quality of oil.
