“…Therefore, foodbiomass-waste valorization would not only minimize pollution, but it would also have the potential to generate biobased compounds, foods, and sustainable energy [2]. Food byproducts, for instance, have been valorized into biocomposites and bioplastics, as has the potential use of industrial biomass waste as an upcoming environmentally friendly energy source [3][4][5][6][7]. Zhang et al [8] investigated energy and heat generation by food biomass waste using a mobile food-waste-to-energy system in conjunction with an anaerobic digester and a biogas engine.…”

In recent years, the production of food biomass waste has been increasing rapidly. This necessitates urgent measures to be taken so as to utilize them. Since most food biomass waste contains useful bioactive substances, cloud-point extraction (CPE) has emerged as a promising solution to valorize waste. CPE is an extraction method employed for the extraction and preconcentration of various chemical compounds, including polyphenols and flavonoids. As with any other extraction procedure, CPE isolates the target compound(s) from the sample, resulting in increased recovery. One major advantage of CPE is that the extraction is carried out without special equipment or harmful reagents. Moreover, other significant advantages are its effectiveness, simplicity, safety, and rapidity. This review focuses on the extraction of bioactive compounds from food-based waste using CPE and highlights the important parameters that can be tuned to improve the performance of CPE. Furthermore, the potential in promoting environmentally friendly practices within the food industry is also discussed.

“…Peels, leftover pulp, and seeds are released into the environment, causing pollution problems, mostly because traditional disposal methods are insufficient, expensive, and harmful [7,8]. For example, their illegal discharge or incineration causes the release of methane and carbon oxide, contributing about 6% of the global greenhouse gases produced together with other wastes [9]. For example, these wastes act as an ideal substrate for developing potentially pathogenic organisms [10], including mycotoxin-producing fungi and insects [11].…”

Citrus consumption translates into large amounts of residue, the disposal of which is associated with environmental issues and high costs. Current trends in citrus waste focus on the extraction of highly valued bioactive compounds via single-compound extraction. There is a lack of knowledge on how these methodologies can be introduced into extraction schemes of bioactive compounds, maximizing the residue potential and reducing its amount. The present work aimed to address this issue by designing a consecutive extraction of pectin and hesperidin from orange peel waste. A novel method for extraction and precipitation of hesperidin with an eco-friendly approach is also presented. After neutral pretreatment, pectin extraction was conducted under acidic conditions, followed by hesperidin extraction with a drastic pH change. Pectin had a high AUA content (66.20 ± 1.25%), meeting the criteria for use in the food industry. The best-tested conditions for hesperidin extraction (30 min, 70 °C, 1:10 (w/v)) provided a yield of 1% and a purity of 84%. The designed extraction scheme shows the potential of citrus waste as a source of bioactive compounds of good quality and high interest in the food industry while following the principles of green chemistry and circular economy.

The rapid growth of organic solid waste has recently exacerbated environmental pollution problems, and its improper treatment has led to the loss of a large number of biomass resources. Here, we expound the advantages of microbial agents composting compared with conventional organic solid waste treatment technology, and review the important role of microbial agents composting in organic solid waste composting from the aspects of screening and identification, optimization of conditions, mechanism of action, combination with other technologies and ultra‐high‐temperature and ultra‐low‐temperature microbial composting. We discuss the value of microorganisms with different growth conditions in organic solid waste composting, and put forward a seasonal multi‐temperature composite microbial composting technology. Provide new ideas for the all‐round treatment of microbial agents in organic solid waste in the future. © 2024 Society of Chemical Industry.
