“…The surfactant is mainly used in the LC biomass case since it helps to inhibit the binding of cellulase with lignin due to the hydrophobic interactions (Okino et al, 2013). Adding surfactant also helps to prevent aggregation of the biomass (Kumar et al, 2018). The surfactant acts as the barrier and does not allow the lignin to bind with the methanogenic enzyme, and hence the methane generation is also enhanced by the addition of the surfactant.…”

Bioenergy recovery from lignocellulosic (LC) biomass is the beneficial and sustainable approach due to its abundant availability. On the Otherhand, its recalcitrant nature makes the biomass to resist biological hydrolysis and it limits the conversion potential of organics to biomethane. Thus, it is essential to evaluate the association among the recalcitrant nature of LC biomass and its biomethane conversion efficiency. Consequently, this review critically recaps the recalcitrance of LC biomass and its effects on bioenergy recovery, its composition and characteristics. In addition, various enhancement approaches (pretreatments) were conferred as main aspect which plays main role in biomass disintegration and biomethane increment. Based on up -to -date information, elevated energy input and cost necessities of the pretreatments are the main factors that mediates the economic feasibility of the process. The present review apart from spotlighting the pretreatment efficiency, it also focusses on the challenges and limitations of enhancement strategies, energy and technoeconomic feasibility of the various pretreatments of LC biomass.

“…However, the excessive temperature may have a negative effect on the subsequent hydrolysis and fermentation process in terms of depolymerization of reduced sugars (Kannah et al, 2020). Two of the most commonly used mechanical pretreatment methods include ultrasonication and disperser (Kumar et al, 2018; Ushani, Banu, Tamilarasan, Kavitha, & Yeom, 2017). Ultrasonication pretreatment results in the generation of vapor bubbles followed by their collapse thus disintegrating the biomass.…”

Food waste is the outcome of different food processing practices that have not been reused and are disposed of as waste. Food wastes are rich in a wide variety of organic constituents including starches, proteins, oils, fats, phosphates, nutrients, amino acids, and natural acids. Food waste is a zero‐value and nonconsumable resource. In this context, the valorization of food waste to different sorts of biofuels, for example, biodiesel, bioethanol, biohydrogen, bio‐oil, biochar, and biomethane by employing well‐structured and efficient valorization technologies can be an attractive and viable approach to counter the current global energy crisis and in establishing a sustainable bioeconomy. This type of food waste management not only resolves the serious pollution problem but also helps to reduce the dependency of the energy sector on fossil fuels. This review discusses the characteristics of food waste, common strategies for food waste management, food waste as a feedstock, biofuels as a renewable energy source, valorization of food waste to various types of biofuels, microbes‐assisted valorization of food waste, biofuels and bioeconomy, and future scope and challenges in the valorization of food waste to biofuels.

“…During the AD process, the major soluble biopolymers such as proteins and carbohydrates were hydrolyzed into amino acids and sugar molecules by fermentative bacteria. During this fermentation study, the soluble compounds can be transformed into VFA by the acetogenic microbes (Yi et al, 2013;Dinesh Kumar et al, 2018). The higher consumption of biopolymers from MAB substrate leads to more VFA accumulation (Jiang et al, 2007).…”

This study illustrated the participation of marine macroalgae biomass (MAB) (Chaetomorphaantennina) in the liquefaction process for bioenergy production. The proposed work intended to investigate the role of disperser pretreatment (DP) and ozone disperser pretreatment (ODP) of MAB for energy efficient biogas generation. The disperser G-force of 1,613 g, pretreatment time 30 min and ozone dosage 0.00049 g O 3 /g Total solids (TS) was preferred as an optimum conditions for profitable and energy efficient liquefaction in term of soluble COD (Chemical oxygen demand) organic release. On comparing DP and ODP, the MAB liquefaction and methane production potential was much higher (20.5%, 0.20 g COD/g COD) in ODP when compared to DP (11.9%, 0.11 g COD/g COD). Therefore, the ODP essentially improve the anaerobic biodegradability of MAB. The economic assessment showed that the ODP was found to have a higher net profit of 71 United states dollar (USD)/ton of MAB compared to DP (4 USD/ton of MAB).
