“…High lingo‐cellulosic waste in these residue is a source for the production of new and sustainable chemicals and fuels (Ranzi et al, ). Many researchers have studied the valorization of citrus waste into biofuels through process of pyrolysis, thermolysis, gasification, and combustion (Alvarez et al, ; Kim, Lee, Kim, Watanabe, & Park, ; Miranda, Bustos‐Martinez, Sosa Blanco, Gutierrez Villarreal, & Rodriguez Cantu, ; Volpea, Pannob, Volpea, & Messineo, ; Zapata, Balmaseda, Fregoso‐Israel, & Torres‐Garcıa, ).…”

“…High lingo-cellulosic waste in these residue is a source for the production of new and sustainable chemicals and fuels (Ranzi et al, 2008). Many researchers have studied the valorization of citrus waste into biofuels through process of pyrolysis, thermolysis, gasification, and combustion (Alvarez et al, 2018 which helps to reduce soil erosion. Siles, Vargas, Gutiérrez, Chica, and Martín (2016) observed that co-composting of waste orange peel combined with organic fraction of municipal solid waste resulted in 37% reduction in odor generated compared to single organic fraction of municipal solid waste.…”

Citrus fruits are major processed fruits in the world that results in generation of large quantities of by‐products, which are rich sources of soluble sugars, cellulose, hemicellulose, pectin, and essential oils. However, very large amount of residues is end up at agriculture field or dumping pit as waste. The present review highlights the technologies and processes for utilization of the citrus by‐products viz., feed for extraction of essential oils, charcoal and bio‐oil production, hydrogen syngas etc. Citrus pulp a very effective agent for removal of metals and chemicals in and effluent generated by industries by adsorption technique. Polymer Electrolyte Membrane Fuel Cell developed by synthesis of activated carbon from citrus pulp is considered to be next generation potential power. In order to make rational use of this valuable resource and protect the environment, the present study aims at comprehensive utilization of this value added by‐products. Practical Applications In the present scenario of fast developing world, the generation of waste is increasing day by day in large quantities which influences the heath of ecosystem and ultimately the human health. Adaptation of advanced technologies and processes is not only a technique of waste management but also generate an alternative to environment polluting substances through development of craft paper, biodiesel, activated carbon along with development of value added food products such as extruded, pectin extraction, essential oils, etc. Increased scope of product development increases the overall returns to manufacturer, employment generation and sustainable socio‐economic development and maintains environmental stability.

“…Spouted Beds (SB) continue to attract interest in recent years for a broad range of applications, mostly related to drying processes, due to the high fluid-solid contact achieved [1]. Spouted beds currently stand out as a promising technology to carry out thermo-chemical reactions such as pyrolysis [2,3], gasification [4,5] and combustion [6,7] of different materials, such as coal or waste products. A Spouted Bed can be described as a conventional fluidisation reactor in which the perforated plate has been replaced by single orifice place, promoting enhanced recirculation of solids with a particular multiphase pattern [8].…”

Highlights  A prismatic spouted bed was modelled using CFD.  A comparison between discrete element method (CFD-DEM) and two fluid model (CFD-TFM) was performed.  Results in terms of accuracy and computational effort were evaluated for each approach.  CFD-DEM provides a better prediction of maximum particle velocity.  CFD-TFM predicts better the height of the fountain. A spouted bed was simulated through two Computational Fluid Dynamic models: CFD-TFM and CFD-DEM. The two models were compared and validated with data from literature, showing good agreement between experimental and simulated results. Both models were able to predict the dynamics of the bed from the static situation to stable spouting conditions, even though some discrepancies in the solid volume fraction or velocity profiles were observed. Overall, CFD-DEM reproduced better the experimental measurements, and, since the computational effort was proved to be similar in both cases due to the low number of particles in the bed, it was preferred to describe the present spouted bed. In larger systems, however, CFD-DEM might not be so convenient, requiring the evaluation of the degree of accuracy and the computational costs prior to the application of this or alternative models.

“…Furthermore, it could attain very low gas residence times, i.e., as low as milliseconds in the dilute spouted-bed regime [15]. The spouted-bed reactor has been successfully used for the fast pyrolysis of both biomass and other residues such as tire, sewage sludge, and plastic [16][17][18].…”

Fast pyrolysis experiments of larch sawdust were conducted in a conical spouted‐bed reactor to study the influences of reaction temperature, inlet gas velocity, feeding rate, and particle size on the product yield and pyrolysis oil quality. For the first time, the optimal conditions were determined for various pyrolysis operations of such reactor to increase the yield and quality of pyrolysis oil. The results demonstrate that the biomass particle size, reaction temperature, biomass feeding rate, and inlet gas velocity all affected the quality and yield of the pyrolysis oil, in this order.
