“…More than 30,000 marine-derived bioactive compounds described so far have been used as valuable sources of food bioactive ingredients, nutraceuticals, cosmeceuticals, pharmaceuticals, and many other applications [39]. In recent years, photoautotrophic organisms have been discussed as a promising candidate for energy sustainable production, with more interest dedicated to algal biomass as third-generation biofuel feedstocks [20,38,41]. They are more advantageous due to the elevated cost of lignin degradation for conversion of second-generation biofuel feedstocks, such as lignocellulosic wastes [42,43], and competition of first-generation edible feedstocks with the available resources [44].…”

“…Recently, seaweed has been discussed as an alternative and renewable energy source [38,92]. Seaweed comprises mainly three groups belonging to red, green, and brown algae [93] that have been discussed for the production of various biofuels [20]. Global seaweed production has been rising rapidly in recent years, reaching 32.4 million tons in 2018 with an average increase rate of 10% over 10 years [94].…”

“…Currently, anaerobic digestion for biogas production is proposed as a promising renewable energy technology for mitigation of climate change by reducing the reliance on fossil-based fuels [19,20]. A wide range of wastes, including municipal and industrial wastewater, energy crops by-products, livestock waste, and food wastes, can be treated using this technology with triple purposes of energy recovery, soil improvement, and waste management.…”

Fossil fuel depletion, climate change, and increased global energy demands are the driving forces to find alternative sources of energy. Marine-based biorefinery has been recently discussed as a promising route to mitigate the environmental challenges, enhance the energy recovery, and provide a potential source for value-added products. Anaerobic digestion is a promising technology that can convert the organic compounds of marine ecosystems into biogas. To date, a comprehensive review incorporating integrated biogas potential and effective approaches to enhance seaweed digestibility for biogas production from marine resources has not been reported. Thus, the present review aims to explore and comprehensively present seaweed and other marine resources for potential biogas production. The basics and challenges of biogas production from seaweed are elucidated. The impact of biochemical composition on biogas and the microbial communities involved in anaerobic digestion of seaweed are discussed. Utilization of different techniques such as pretreatment, co-digestion, and sequential extraction of seaweed biomass to enhance the biogas yield and to mitigate the effect of inhibitors are presented. Specifically, this article evaluates the co-digestion of seaweed with other biomass feedstocks or liquid biowastes. Integration of marine microalgae cultivation on anaerobic digestate for value-added compound production, biogas upgrading, and bioenergy recovery provides a promising approach towards a zero-waste marine-based system.

“…Biofuels and bio-based products are among the best alternatives to fossil-based fuels and chemicals due to their capacity for net-negative carbon emissions, which is a vital contribution to the global ambition of a net-zero economy [1][2][3]. Biorefinery could enhance the overall energy output and the economic feasibility of biomass conversion [4].…”
