“…juices) fruits, represents the most economically viable fruit market. The most abundant citrus fruits are oranges (El Kantar et al, 2018) which are mainly cultivated in Brazil, United States, Mexico, China, and in the Mediterranean basin (Zema et al, 2018). According to the Food and Agriculture Organization of the United Nations, the world production of orange juice is on a constant increase, reaching 71 million tonnes in 2014 (FAO, 2015).…”

“…According to the Food and Agriculture Organization of the United Nations, the world production of orange juice is on a constant increase, reaching 71 million tonnes in 2014 (FAO, 2015). Industrial processing generates large amounts of solid residues, mainly peels, which represent over 50-60% (wb) of the fruit itself (Calabrò et al, 2018a;Zema et al, 2018). Several approaches have been investigated in managing these wastes.…”

“…Several approaches have been investigated in managing these wastes. Fresh orange peels (OP) were largely used in the past as cattle feed due to the positive effects produced on lactation in cows (Calabrò et al, 2018a); however, environmental and economic concerns (such as percolation, odour emissions, insufficient demand) have limited use of this solution (Zema et al, 2018). Currently however, the majority of OP generated yearly are not valorised and require appropriate treatment or disposal.…”

“…Currently however, the majority of OP generated yearly are not valorised and require appropriate treatment or disposal. OP are composted to produce fertilizers (Calabrò et al, 2018a), alcoholically fermented to obtain bioethanol, anaerobically digested to recover biogas (Zema et al, 2018) or landfilled (Calabrò et al, 2018b). However, because of the low pH (around 3-5) and fast biodegradation rate, citrus waste is generally not well accepted in composting plants and may cause anaerobiosis problems in the compost piles (Martin et al, 2018;Ruiz and Flotats, 2014).…”

Biological Metabolites Recovery From Beverage Production Solid Residues Through Acidogenic Fermentation

Acidogenic fermentation was applied to evaluate the potential recovery of biological monomers as precursors in bio-plastic production. Three residual organic substrates from high-volume beverage sectors (coffee, orange juice, beer) were assessed: spent coffee grounds (SCG), orange peels (OP), and brewers' spent grains (BSG). Batch fermentation tests were set up. SCG and OP were studied as single substrates and combined to evaluate yields of target monomers (volatile fatty acids, ethanol, lactate) and to reveal interactions between the matrixes. NaOH pre-treatment was applied to SCG to enhance disruption of the lignocellulosic cell wall. BSG was studied without pre-treatment and following acid or alkaline pre-treatment, with acidogenic fermentation being initiated with two different initial pH values (7; 9). Acetogenic fermentation was achieved with all substrates, although with different yields of target monomers. In terms of total biological metabolite production, following alkaline pre-treatment, OP and BSG, both fermented at an initial pH 9, showed the best performance, yielding 62.6 g and 62.0 g target monomers per litre substrate. For all substrates, acetic and butyric acids were the most abundant products. In the case of OP fermentation, butyrate accounted for 57% (35.8 g/L) of the total. The BSG test with the highest total yield also achieved the highest acetate yield (36.7 g/L). The results confirm that OP and BSG should be considered a priority sustainable feedstock for the supply of biological monomers, particularly if polyhydroxyalkanoates are to be produced. SCG are better suited to aceto-oriented approaches, such as the production of polyvinyl acetate.

“…A pureza obtida para a pectina foi de 96,5%, valor similar (95,0%) ao apresentado porPourbafrani et al (2010). Apesar do processo simulado nesse trabalho ter sido desenvolvido com base em dois trabalhos com etapas de hidrólise e precipitação distintas, os valores referentes ao rendimento e a pureza são comparáveis, o que corrobora para validação do modelo de simulação apresentado Zema et al (2018). em um reator semi-contínuo em escala piloto.…”

Agradeço pelo olhar humano e pelas palavras de incentivo nos momentos difíceis. Muito obrigada! A Dra. Cláudia Echevenguá Teixeira que com o seu jeito único me acolheu, me orientou e sem hesitar dividiu um pouco do seu conhecimento comigo. Obrigada por me ensinar através do exemplo a ser uma mulher forte e independente no ambiente de trabalho. Aos meus avós por me criarem na ausência necessária dos meus pais com carinho, alegria e bondade. Muito obrigada por me ensinarem o valor do trabalho, a ser resiliente e a nunca duvidar de que no final tudo sempre dá certo. Conseguimos! Aos meus pais Douglas, Janaína e Wesley pela presença constante, apoio incondicional, momentos de carinho, conselhos e pelo luxo de apenas viver, porque todo o resto vocês fizeram por mim. Sem vocês eu nada seria. Aos meus familiares pelo incentivo, palavras doces, conselhos e bons momentos que me enchem de força para transpor os desafios diários. Aos meus irmãos de alma Amanda, Marcos e Meire por estarem sempre presente, por me entenderem de forma singular, compreenderem minhas franquezas e ausências. Obrigada por escolherem ficar mesmo não sendo necessário. A vida com vocês é mais feliz e cheia de amor. Aos meus amigos de Brasília, aos que fiz em São Paulo agradeço por dividirem bons momentos comigo e contribuírem com a forma como enxergo a vida.

The present study focuses on a bibliometric analysis of the global production of scientific papers related to the recovery of bioenergy from orange industrial waste or by-products. The study also observed the top-cited papers, international collaborative networks, top countries, and journals. The timespan was from 1900 to 2019, and the Web of Science © database was used. A total of 161 documents (research and review papers) were selected to carry out the investigation. Two main clusters of literature were highlighted, related to the authorship of the top-cited papers and authorship collaboration networks, respectively. Recent scientific publications use different pre-treatments to achieve the best biogas yield with many configurations of the anaerobic digestion system. The data indicated that the countries with most publications are Spain, China, and the USA, and the journals with a higher impact factors related to environmental assessments were responsible for a higher number of publications. In a biorefinery concept, orange peel could be submitted to different pre-treatments to produce bioethanol and methane, as environmentally friendly fuels, and other co-products such as d-limonene and pectin. This study therefore presents trends in bioenergy production from orange industrial by-products with the aim of supporting further research on energy recovery from orange industry solid waste and to assist future decision making in this field of science.
