In the last decades problems concerning waste disposal have assumed increasing interest due to the growth of their production and typologies following consumption escalation. In an advanced industrial society waste constitute one of the main aspects concerning environment protection; their impact is linked to material quantity, typology and persistence into the environment. A correct waste management must be included within an integrated strategy of sustainable development: among the necessary actions aimed to reduce flows to landfills, regulations particularly indicate reduction of resource use, energy recovery, use of waste as a resource. Until today in Italy a sustainable management system has not been implemented yet, making frequent use of temporary solutions which only delay the problem come up. Within this frame, in the paper a case study has been analysed, referring to the collection and delivery system of Urban Solid Waste in Reggio Calabria, carrying out an analysis of the management process from an economic, energetic and environmental point of view. Analysing the phases following the collection (waste selection, transport, treatment), a critical evaluation of the used technologies has been conducted, assessing cost, energy consumption and pollutant emission. The analysed case has finally been compared with different scenarios, showing increasing percentage of differentiated collection, relating them to the least advanced disposal modality, landfill.

“…Due to an orange peel's complex lignocellulosic composition, pre-treatment is required to facilitate its use in several applications. 6,37,38 Key words selected for the collection were 'orange peel' , 'orange waste' , 'anaerobic digestion' , 'biogas' , 'methane' , 'hydrogen' , and 'pre-treatment' . These words were used for research in Web of Science (WoS), a scientific database that gathers information about scientific studies, with the boolean operators 'OR' and ' AND' .…”

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.

“…Different techniques, such as recycling, incineration, and landfilling, are being used for the treatment of wastes material. Among these techniques, recycling is considered to be the most effective method for managing wastes material in terms of greenhouse gas emission and for energy recovery [10,11]. The high organic fraction of molasses is attributed to its high sucrose content, and sucrose can be used as a substrate in bio-refineries and is possibly involved in several microbial pathways [2].…”

Molasses is a highly dense and refined byproduct produced in the sugarcane industry, and it contains high amounts of degradable compounds. Through bioconversion, these compounds can be transformed into renewable products. However, the involved biological process is negatively influenced by the high chemical oxygen demand (COD) of molasses and ion concentration. The co-digestion of molasses with rice-alcohol wastewater (RAW) was compared with its mono-digestion at an increasing organic loading rate (OLR). Both processes were assessed by detecting the COD removal rate, the methane contents of biogas, and the structure and composition of microbial communities at different stages. Results showed that the co-digestion is stable up to a maximum OLR of 16 g COD L−1 d−1, whereas after the acclimatization phase, the mono-digestion process was disturbed two times, which occurred at a maximum OLR of 9 and 10 g COD L−1 d−1. The volatile fatty acids (VFAs) observed were 2059.66 mg/L and 1896.9 mg/L, which in mono-digestion causes the inhibition at maximum OLRs. In the co-digestion process, the concomitant COD removal rates and methane content recorded was 90.72 ± 0.63% 64.47% ± 0.59% correspondingly. While in the mono-digestion process, high COD removal rate and methane contents observed were 89.29 ± 0.094% and 61.37 ± 1.06% respectively. From the analysis of microbial communities, it has been observed that both the bacterial and archaeal communities respond differently at unlike stages. However, in both processes, Propionibacteriaceae was the most abundant family in the bacterial communities, whereas Methanosaetaceae was abundant in the archaeal communities. From the current study, it has been concluded that that rice-alcohol wastewater could be a good co-substrate for the anaerobic digestion of molasses in terms of COD removal rate and methane contents production, that could integrate molasses into progressive biogas production with high OLR.
