“…Gu et al (2018) reported on planetary ball milling of post-harvest forest residues, yielding the maximal glucose and xylose/mannose of 59.67% and 23.83%, respectively, with low energy input ranging between 0.20-2.15 kWh/kg for 7 to 30 min of milling. The parameters to be considered for effective milling operation include feeding rate of biomass, initial biomass size, machinery parameters, time, and moisture content (Amin et al, 2017;Jędrzejczyk et al, 2019).…”

“…Rooni et al (2017) found out that four cycles of freezing at -18°C and thawing at 22°C, resulted in the highest glucose yield. Microwave-assisted pretreatment has also been found to be very effective in pretreating switchgrass and miscanthus (Jędrzejczyk et al, 2019). Microwave irradiations provide an easy operation, high heating capacity at short times, and no inhibitor is formed.…”

“…Nevertheless, the duration of microwave is an important factor to be taken into account for effective pretreatment. A longer exposure time may lead to inhibitor generation and degradation of reducing sugars (Jędrzejczyk et al, 2019). Microwave is generally used in combination with chemical pretreatments for higher pretreatment efficiency.…”

“…The main drawbacks of acid pretreatment include, 1) inhibitors generation which requires extensive washing or neutralization prior to fermentation and 2) corrosive nature of acid corroding reactors (Kumar and Sharma, 2017). Hydroxymethylofurfural and acetic acid formed during acid pretreatment (at a concentration of 2 g/L and 3 g/L, respectively) have shown inhibitory effect on the subsequent fermentation (Jędrzejczyk et al, 2019).…”

“…Organosolv is a mixture of organic solvents capable of solubilizing hemicellulose and extracting lignin. The commonly used organic solvents used as catalyst for the organosolvation reaction are methanol, ethanol, acetone, ethylene glycol with organic acids like oxalic, salicylic, and acetylsalicylic (Jędrzejczyk et al, 2019). This technique results in delignification and complete solubilization of hemicellulose (Jędrzejczyk et al, 2019).…”

Keywords:Lignocellulosic biomass has been recognized as promising feedstock for biofuels production. However, the high cost of pretreatment is one of the major challenges hindering large-scale production of biofuels from these abundant, indigenouslyavailable, and economic feedstock. In addition to high capital and operation cost, high water consumption is also regarded as a challenge unfavorably affecting the pretreatment performance. In the present review, advances in lignocellulose pretreatment technologies for biofuels production are reviewed and critically discussed. Moreover, the challenges faced and future research needs are addressed especially in optimization of operating parameters and assessment of total cost of biofuel production from lignocellulose biomass at large scale by using different pretreatment methods. Such information would pave the way for industrial-scale lignocellulosic biofuels production. Overall, it is important to ensure that throughout lignocellulosic bioethanol production processes, favorable features such as maximal energy saving, waste recycling, wastewater recycling, recovery of materials, and biorefinery approach are considered.
