“…The results show how the intensification of recycling efforts can reduce expanded polystyrene waste and present new business models in the context of sustainable development from the circular economy. In the same line, in the agribusiness sector of orange juice in Colombia (Ortiz et al , 2020) are analyzed the environmental footprints of each options of orange peel waste recovery, such as incineration and anaerobic digestion.…”

PurposeIn this paper, the authors adopt the theory of the circular economy to study the transitions that take place in three case studies in Mexico and Ecuador. The work is aimed to systematize a circular economy assessment tool that fosters opportunities for improvement in business practices.Design/methodology/approachThe methodology is based on a descriptive quantitative analysis, where a checklist is made with 91 items and nine study variables. This is from the study of the bibliography and business practice. Furthermore, the neural network method is used in a case study to predict the level of circular economy and the importance of each variable according to the sensitivity by the Lek’s profile method.FindingsIt is based on a descriptive quantitative analysis, where a checklist with 91 items and nine study variables is made, defined from a bibliographic study and business practice. Furthermore, the neural network method is used in a case study to predict the level of circular economy and the importance of each variable based on sensitivity.Research limitations/implicationsThe application of the tool requires prior knowledge of the circular economy approach, which is why specialized personnel are needed for its application. This makes research more expensive in time and human resources.Practical implicationsThe practical and methodological contribution of this work lies in the feasibility of the tool that favors the definition of improvement actions for the implementation contribution to the circular economy in business practices.Social implicationsThe social contribution is framed in the gradual transition to circular economy approaches in underdeveloped countries.Originality/valueThe use of the neural network method to predict the level of circular economy in a case study allows making decisions in a predictive way. This encourages the development of the circular economy according to the context needs.

“…Additionally, during the production of industrial orange juice only half of the fresh weight of orange is transformed into juice and the 50% remaining (228.150 tons) consists of pulp, peel and seeds (Rezzadori et al 2012). Approximately 95% of these agro-industrial wastes are made from peels (orange and lemon peel residues) generating a serious disposal problem which implies the use of extensive economic and energy resources, in addition to risk increase of air, water and soil pollution because of the pollution (Ortiz et al 2020). In this work, two different types of citric acid source were tested, performing an aqueous extraction of lemon and orange peel, due to the high amount of fruit peel in organic waste, generated by the domestic sector (Villegas-Guzman et al 2017).…”

In this work, the photoelectro-Fenton system was evaluated as an alternative for the degradation of sulfamethoxazole and trimethoprim at unmodi ed pH by using citric acid present in extracts from a natural source as organic residues (orange and lemon peels). The addition of natural citric acid showed an e cient degradation of the antibiotics similarly to the e ciency by adding commercial reagent citric acid. The observed high e ciencies and rate constants are attributed to the increment of ferrous ion in the solution due to the fast conversion of iron form its ferric to ferrous state leading to the Fenton reaction and so increasing the hydroxyl radicals production. Although the addition of citric acid present in the extracts slightly increases the organic matter of the solutions, the degradation of the antibiotics was achieved simultaneously and e ciently, converting the photoelectro-Fenton process with the addition of natural citric acid into an alternative ecological system and sustainable for water contaminated with pharmaceutics. Additionally, the high biodegradable character and low ecotoxicity of the treated solutions were determined by a modi ed Zahn Wellens test and a bioassay with D. magna, respectively. Finally, simultaneous degradation of sulfamethoxazole and trimethoprim was reached after only 45 min of treatment in which the antibacterial activity was completely eliminated, suggesting that degradation products do not represent any environmental risk nor human health. HighlightsSMX and TMP were simultaneously degraded with the PEF process by citric acid addition. E ciency in the degradation was maintained with lemon and orange peels extract.Complete degradation of SMX and TMP increased the biodegradability of the treated solutions.The treated SMX-TMP solutions showed lower ecotoxicity.

“…In this study, authors studied whether burning and anaerobic digestions are potential options for burying waste from a technical, economic, and environmental perspective. Results revealed that if these powders are properly dried, their stability and value will be considerably enhanced (Ortiz et al 2020).…”

Sustainability and Circular Economy of Food Wastes: Waste Reduction Strategies, Higher Recycling Methods, and Improved Valorization

In this review, the issue of food recycling was comprehensively studied from the perspective of recent research. Firstly, the concept of circular economy and its application in reducing waste production and the strategies for waste reduction (waste prevention) were discussed. The concept suggests that we can produce less waste from the beginning to reduce costs for recycling, instead of generating much waste for recycling through specific approaches. Secondly, the results of several investigations on the recycling of various food wastes, which have been less considered important parts of waste management, such as university waste, agricultural waste, food industry waste, and spent coffee ground (SCG) waste, were discussed in detail. Finally, various methods for recycling and sustaining food wastes (improving the rates of recycling) and their application in aforementioned sections were comprehensively presented.
