“…Macroalgae is a particularly rich source of carbohydrates in bioethanol production. Due to the high carbon and low lignin content of algae raw materials, the thirdgeneration bioethanol, which uses algae as raw materials, has higher octane number, higher heat of vaporization, and less greenhouse gas emissions (Yahmed et al 2018). The production of bioethanol from macroalgae consists of mechanical pre-processing, pretreatment, and microbial fermentation.…”

Due to the combined pressures of energy shortage and environmental degradation, bio-liquid fuels have been widely studied as a green, environmentally friendly, renewable petroleum alternative. This article summarizes the various technologies of three generations of biomass feedstocks (especially the second-generation, biomass lignin, and the third-generation, algae raw materials) used to convert liquid fuels (bioethanol, biodiesel, and bio-jet fuel) and analyzes their advantages and disadvantages. In addition, this article details the latest research progress in biomass liquid fuel production, summarizes the list of raw materials, products and conversion processes, and provides personal opinions on its future development. The aim is to provide a theoretical basis and reference for the optimization of existing technology and future research and development of biomass liquid fuels.

“…Bioconversion is a technology used to transform biomass into bioenergy and high added-value products (Smaali et al, 2009, Djaafri et al, 2020, Ben Yahmed et al, 2018. This technology offers several advantages: it is simple, mature, environment friendly, cheap, renewable, helping to reduce the environmental impact of waste disposal (such as agricultural residues, organic animal, vegetable and industrial waste...) and represent a good alternative to fossil fuels (Djaafri et al, 2020).…”

Date production is usually associated to a considerable loss either in common cultivars or in fruit picking and storage stages. This discarded biomass is not very well valued up to now especially in bioenergy production. The Tunisian second-grade cultivar 'Kenta' was biochemically characterized in the present study. 'Kenta' discarded flesh is rich in soluble sugars (79.5 %VS ± 0.8%VS) and fibers (7.4 %± 0.5%VS). The crude fibers were recovered after soluble sugars extraction. The biochemical composition analysis showed that this by-product contains mainly carbohydrates (33.2 % VS± 0.7%VS) and proteins (8.8% VS ± 0.1% VS) making it a suitable feedstock for biogas production. A biorefinery concept was therefore developed based on soluble sugars (date-syrup) aqueous extraction and biogas production via anaerobic digestion of the residual fibers. The proposed concept showed interesting results since it permitted the coproduction of date syrup, as high-added value product, with 0.6 g sugars/gVS and biogas with maximum methane yield of 225 mL CH4/gVS fibers. This study presents a proof of a sustainable processing approach allowing an almost bioconversion of undervalued secondary date variety and integrates the concept of circular bio-economy.
