Abstract This work aims to evaluate the technical and environmental feasibility of converting date palm waste from a Moroccan oasis into energy. In this study, two different scenarios were analysed. The first proposed scenario is the valorization of the date palm substrates using direct combustion (thermochemical conversion) to produce energy. The second proposed scenario is the valorization of the substrates using combined anaerobic digestion of the substrate and direct combustion of the digestate. In this study, two different date palm wastes are: empty fruit bunch (EFB) and palm leaflet (PL). The experimental lower heating values of the digestates studied are 12.93 and 12.71 MJ/kg, respectively. The results show that using Scenario 1, the estimated output energies for the EFB and PL waste were 1.13 and 1.17 MWh, respectively. Using Scenario 2, the EFB and PL output energies were 1.27 and 1.39 MWh, respectively. The study revealed that the combined process is possible as an alternative way to produce energy. Furthermore, combining anaerobic digestion and direct combustion of lignocellulosic waste can contribute to reducing greenhouse gas emissions.

Coffee is present in every street in the world and is without a doubt one of the most consumed beverages. More - over, it is the third most consumed drink in the world. Recent estimations from the International Coffee Orga - nization put. The world coffee production at about 6 million tons per year. Its uncontrolled disposal can cause environmental problems, but if handled properly, it can be processed into pellets, and used as an energy source. In the present study, the production of energy from coffee waste (CW) is an interesting alternative to traditional production lines. The objective of this study is to calculate the energetic potential (Ep), which can be generated by anaerobic digestion (AD) and thermochemical conversion (TC), of the organic fraction of CW in the city of Keni - tra, Morocco. An elementary analysis allows us to estimate the calorific value by the TC. The lower and higher calorific values were estimated to be: 18.71 and 20.28 MJ/Kg, respectively. Ep results by AD and CT were 0.25 and 1.3 MWh/t, respectively.

ABSTRACT A large quantity of lignocellulosic biomass is generated annually across the world which leads to environmental pollution and requires valorization. This study investigated the effect of hydrothermal pretreatment on the anaerobic digestion and co-digestion of the residual pepper plant and eggplant with a focus on kinetics. Two thermal hydrolysis rates were observed, with the optimal conditions for the hydrothermal pretreatment of lignocellulosic biomass being 120°C for 40 min. Subsequently, single and combined biomethanization was successfully carried out in laboratory-scale completely stirred tank reactors at mesophilic temperature (35°C). A high increase in methane production was observed after the pretreatment of the pepper plant and eggplant. The pretreated and co-digested wastes led to an optimal methane yield of 79 ± 23 mL CH4/g VS. The modified Gompertz model was used to fit the cumulative methane production of the pretreated lignocellulosic substrates. The kinetic model adequately reproduced the experimental results and might be considered a useful tool to simulate the biomethanization behaviour of complex organic substrates. GRAPHICAL ABSTRACT

Anaerobic digestion of the date palm empty fruit bunch is a promising technology for both solid waste management and biogas production. The date palm empty fruit bunch is a lignocellulosic waste that takes more time for degradation and has a low biodegradability, thus pretreatment is needed to improve anaerobic biodegradation. In this study, the substrate was pretreated with different ratios of alkali-NaOH: 6, 18 and 30% (w/w) (ratio weight of NaOH / weight of Volatile Solid) for 10 min at room temperature to evaluate the effect of high alkali concentration on the methane potential and biodegradability. The experiment was conducted in a 5 L batch reactor under mesophilic conditions (37 °C). The methane potential of the untreated substrate was 98.5 N mL/gVS. The best methane potential improvement of 104% was achieved in the treatment of 18% (w/w) (204 N mL/gVS) with a biodegradability of 50%. Besides, two kinetic models were used to fit the experimental methane potentials and to explore process parameters (Modified Gompertz and Transference function). The best fit for predicting the parameters of methane production was observed for the 18% (w/w) pretreatment using the transference function, with a maximum methane production rate of 5 N mL/gVS.d.

This paper investigates the influence of thermal pretreatment on kinetic parameters based on four kinetic models: Modified Gompertz, transference and logistic functions and first order equation. The kinetic modeling was applied on experimental results of previous study on producing methane from anaerobic digestion of Recycled Pulp and Paper Sludge (RPPS) under mesophilic conditions. We observed that the thermal pretreatment improve considerably improved the kinetic parameters mainly the methane production rate and the lag phase. Indeed, it can be noted that methane production rate μ increases significantly from a value of 4.72 to 16.27 ml/h using logistic function for 1 g VS/L added load. Then the lag phase parameter λ has dramatically decreased from 5.46 to 1.04 h using logistic function for 1.5 g VS/L added load. This means that the thermal pretreatment of RPPS accelerates the methane production process and saves time.

Due to the increasing population around the globe, requirements for energy are increasing day after day. The conventional approaches for energy production may not be sufficient to meets these requirements. This necessitates energy production from different renewable sources through suitable techniques. In the present study, energy recovery from palm leaflet waste (PLW) in Morocco was examined. PLW is the by-product of palm farms and is usually burnt in the field or barren lands. This causes the emission of carbon dioxide (CO2) and of other air pollutants, as well as the outbreak of fires in the fields, which destroy a large number of palms. The purpose of this study was to identify and calculate the theoretical energetic potential (Ep) that can be recovered from PLW using anaerobic digestion (AD) and thermochemical conversion (TC) i.e., combustion. To estimate the theoretical heating value for TC, an elementary analysis was used. The processes of AD and TC on PLW led to the generation of energetic potentials (EP) of 69.81 GWh/y and 235.5 GWh/y, respectively. This work could be used as a guide by the countries having the same nature of biomass to make a preliminary energy study. This would ultimately lead to the development of processes that can end the energy crisis worldwide.
