“…Lignocellulosic biomass from halophytes for ethanol production proved advantageous both in term of high net productivity and low maintenance costs [ 17 ]. Considering the advantages of second-generation biofuels, it is recommended that biofuel production be increased up to 10–20 EJ a year by 2050 [ 127 ] and the share of biofuels in the transport sector be increased from 3% to 8% worldwide between 2013 and 2035 [ 128 ].…”

Due to steadily growing population and economic transitions in the more populous countries, renewable sources of energy are needed more than ever. Plant biomass as a raw source of bioenergy and biofuel products may meet the demand for sustainable energy; however, such plants typically compete with food crops, which should not be wasted for producing energy and chemicals. Second-generation or advanced biofuels that are based on renewable and nonedible biomass resources are processed to produce cellulosic ethanol, which could be further used for producing energy, but also bio-based chemicals including higher alcohols, organic acids, and bulk chemicals. Halophytes do not compete with conventional crops for arable areas and freshwater resources, since they grow naturally in saline ecosystems, mostly in semi-arid and arid areas. Using halophytes for biofuel production may provide a mid-term economically feasible and environmentally sustainable solution to producing bioenergy, contributing, at the same time, to making saline areaswhich have been considered unproductive for a long time -more valuable. This review emphasises on halophyte definition, global distribution, and environmental requirements. It also examines their enzymatic valorization, focusing on salt-tolerant enzymes from halophilic microbial species that may be deployed with greater advantage compared to their conventional mesophilic counterparts for faster degradation of halophyte biomass.

“…To meet the increased demand for energy needs and to reduce greenhouse gas emissions, the capacity of worldwide installed renewable energy systems has been doubled over the last decade [1][2][3][4][5]. This also applies to biogas as a source of renewable energy, where the number of biogas plants installed in Europe has been increased from 6227 in 2009 to reach 18,202 by the end of 2018 [6].…”

The biogas production technology has improved over the last years for the aim of reducing the costs of the process, increasing the biogas yields, and minimizing the greenhouse gas emissions. To obtain a stable and efficient biogas production, there are several design considerations and operational parameters to be taken into account. Besides, adapting the process to unanticipated conditions can be achieved by adequate monitoring of various operational parameters. This paper reviews the research that has been conducted over the last years. This review paper summarizes the developments in biogas design and operation, while highlighting the main factors that affect the efficiency of the anaerobic digestion process. The study’s outcomes revealed that the optimum operational values of the main parameters may vary from one biogas plant to another. Additionally, the negative conditions that should be avoided while operating a biogas plant were identified.

Avicennia marina is the only naturally occurring mangrove specie in the arid Arabian Gulf coast of the United Arab Emirates (UAE). Due to the water scarcity of this arid-region, A. marina is a precious biomass resource for the UAE that does not require fresh water for growing, and is able to grow in the Arabian Gulf high salinity conditions, over 40g/kg. This non-fresh water lignocellulosic arid-region bioresource may be used for the production of high valuable chemicals. The objective of the present manuscript is to characterize the lignocellulosic composition of Arabian Gulf A. marina, as a first attempt to highlight its importance in a biobased economy in arid regions. Avicennia marina stem, leaves and pneumatophors samples were collected from two locations in the United Arab Emirates. A. marina samples were chemically characterized for sugar composition, ash content and byproducts using standardized protocols. The analysis revealed that A. marina arabinan, xylan, glucan and lignin composition ranges, in g/100g_TS (TS: total solids), between 1-22, 5-18, 10-31, and 21-48, respectively. The highest composition of xylan and glucan (g/100g_TS) was obtained for stems and pneumatophors, 45 and 38, respectively. Xylan and glucan are the polymeric precursors for the production of high value chemicals, e.g. furfural and hydroxymethylfurfural (HMF), respectively. Under the characterization conditions, it was obtained furfural and HMF (g/100g_TS) in the ranges of 0.05-0.42, and 0.45-2.1, respectively.
