This study analyses the sustainability of a bioenergy system fed by residual biomass with high moisture content (citrus peel), which is designed in cogeneration mode and integrated with the factory generating the residue. The impacts of electricity production are comprehensively assessed by conducting thermodynamic and environmental analyses with a life cycle approach. Two scenarios were analyzed considering the differences in the process layouts between juice factories. The first scenario with wet feedstock (Scenario W) includes the drying process in the bioenergy plant's boundaries. A second scenario uses dry feedstock (Scenario D), and the drying process is considered outside the boundaries. The thermodynamic performances are assessed by life cycle energy/exergy efficiencies, the cumulative exergy demand of non-renewable resources (CExDnr), and energy/exergy return on investment. Additionally, a new renewability indicator is introduced, hereby named Integrated Renewability (IR), to consider the origin (renewable or non-renewable) of the resources substituted by the side products. The Life Cycle Assessment shows that the scrubbing process, fed with bio-oil, could undermine the system’s sustainability. The overall exergy efficiency was determined to be 0.29 and 0.24 for Scenario D and Scenario W, respectively. Compared to the electricity from the national grid (Italy), the integrated bioenergy system leads to lower life cycle exergy efficiencies in both scenarios (0.24 and 0.20 for Scenario D and Scenario W, respectively, Vs. 0.34 for national grid), higher IR (3.1 and 1.5 Vs. −0.9), lower CExDnr (0.32 and 0.33 vs. 1.9 MWh/MWhe), and lower climate change impacts (−332 and 1.29 vs. 447 kgCO2/MWhe).

The energy sustainability of producing biofuel from wet bioresidues needs proper energy integration to ensure sustainable exploitation. This study analyses the potentials of combined hydrogen, heat, power, and LOHC (Liquid Organic Hydrogen Carrier) production from the residues of citrus juice production, at a factory scale. In this work, the main constituents of LOHC are DME (Dimethyl ether) and methanol. The proposed system is based on air-steam gasification and direct CO2-to-DME process, integrated with hydrogen purification and a CHP unit. The DME reactor is operated at 30 bar in the temperature range 493-533 K. A thermodynamic model, which is validated experimentally, simulates the proposed polygeneration system. In addition to the potential amount of biofuel, hydrogen production, and net power production, the energy and exergy efficiencies are analyzed. Despite the variation of LOHC yield with the temperature, the results show that the whole system’s energy efficiency is not affected, while the small difference among the exergy efficiencies is negligible.

This work aims at developing a comprehensive methodology defining the influence of the proper feedstock management, number and location of gasification-power plants, and process configuration based on the thermodynamic performances of the proposed system under different scenarios. The feedstock was citrus peel from local citrus processing factories. A three-step model was adopted: best site criteria decision tool, location-allocation analysis by minimising energetic transport costs, energy/exergy and emissions analysis. This model was applied to three process scenarios. In the first, we considered a wet biomass (65% water content) dried at a local plant using cogenerated heat; in the second, the biomass dried prior to transportation (15% water content) used to power the combined heat and power plant. The cogenerated heat fed an Organic Rankine Cycle (ORC) unit. In the third, the cogenerated heat is used for district heating. The scenario analysis showed that the regional potential for producing renewable electricity from citrus peel gasification is 66.7–74.6 GWh. Results showed that the Energy Return on Investment (EROI) is <1 only when the feedstock is transported dry (15% water content), and the cogenerated heat is used for additional power production in an ORC unit. The highest EROI values (24–47) are obtained when the feedstock is transported wet and dried using the cogenerated heat. A sensitivity analysis reveals that the optimal number of plants is three with a reduction of the energetic transport cost of 46% compared to a single plant. The maximum global energy and exergy efficiencies were 39% and 16%, respectively. The exergy-based renewability indicator showed that the proposed bioenergy system could be considered renewable in only one of the three process scenarios.

This study analyzes the energy sustainability of citrus residues conversion and valorization through fluidized bed gasification plant. An energy analysis of the integration into a real citrus juice factory of a combined heat and power system (CHP), coupled with a citrus residues air-steam gasification unit, is presented. Energy and biomass assessments are estimated by matching the gasification unit performance with the syngas request of the CHP unit through an integrated simulation model. Results show that the integration of a gasification-CHP system into the juice industrial cycle could supply 7,875 MWh/year of electricity, corresponding to 88% of the factory’s demand. About 82% of the heat produced in the CHP unit is used to dry the citrus residues, while about 1,086 MWh/year are available for the heat request of the juice production process. This allow saving 27,906 MWh/year of non-renewable primary energy, reducing the specific non-renewable primary energy consumption of about 46% the factory’s carbon dioxide impact could be decreased of about 45%.

The present study investigates steam gasification kinetics of chars from six agro-industrial biomass residues (citrus pomace, grape pomace, reed, olive pomace, reed lignin and straw lignin). Experiments were performed in a TGA in steam/N2 mixtures at different temperatures and steam partial pressures. Kinetic parameters are determined by fitting computed char conversions to experimental char conversions. The conversions curves are computed using recently suggested models which are selected based on the K/(Si + P) ratio. The objective of the study is threefold: (1) to determine kinetic parameters for agricultural biomass chars, (2) to validate the models and (3) to test whether a unified activation energy can be used to predict the char gasification times. The activation energies varied between 135 and 165 kJ/mol, and the reaction orders with respect to steam varied between 0.4 and 1.0 for the investigated chars. By using a unified activation energy of 150 kJ/mol for all of the chars, computed char gasification times were in good agreement to experimental measurements. The results support recommendations that the choice of kinetic models should be based on the K/(Si + P) ratio of the chars. The introduction of an Avrami-Erofeev model allowed predicting the conversion behavior of the chars that showed sigmoidal conversion.

Gasification and pyrolysis are very promising technologies for clean energy production especially from low rank fuels. Biomass and wastes with high chlorine, alkali and even heavy metals content are fuels preferential for thermal utilization. However, several problems during combustion in conventional steam boilers occurs e.g. slagging, fouling, chlorine corrosion, boiler efficiency deterioration. New efficient and cost effective technologies are needed, even in small-scale applications. The main objective of this work was to compare the thermochemical behaviour and process parameters effects of different biomass under air gasification and pyrolysis conditions. Three important fuels for European power industry were selected: woody biomass and two residual biomass, such as oat straw and dried citrus wastes. In order to evaluate the possibility to use different feedstocks or to combine and/or integrate them in thermochemical processes, a comparison among typical and untypical feedstocks is needed. Tests performed on small scale fixed bed reactor show the gas yield, its composition and LHV parameter. The results were performed in Royal Institute of Technology (KTH) in Sweden during BRISK program (Biofuels Research Infrastructure for Sharing Knowledge).

Several researchers have shown how sisal fibres possess remarkable tensile properties that yield them good candidates as reinforcement in biocomposite materials. This work aims to evaluate the effect of an eco-friendly and cost effective surface treatment method based on the use of commercial sodium bicarbonate (i.e. baking soda) on properties of sisal fibre and its epoxy composites. In particular, raw sisal fibres were treated with a 10%w/w of sodium bicarbonate solution for different periods (24, 120 and 240 h), at room temperature. Changes occurring in sisal fibres were characterized through scanning electron microscope, Fourier transform infrared spectroscopy, thermogravimetric analysis and helium pycnometer analysis. The mechanical characterization of sisal fibre was carried out through single fibre tensile tests and a reliability analysis of the experimental data was performed. A mathematical model was also applied to investigate the relation between the transverse dimension of the fibres and their tensile properties. Interfacial adhesion of sisal fibre with an epoxy matrix was investigated using single fibre pull out technique. Moreover, to deeper investigate the effect of the proposed treatment, epoxy based composites reinforced with short randomly oriented sisal fibres were manufactured and characterized by means of quasi-static flexural tests. The experimental results showed that 120 h is the optimum time for treating sisal fibre to achieve highest interfacial adhesion and mechanical properties with epoxy matrix.
