“…The results showed that the methane yield was inversely proportional to particle size, with respect to a best result obtained from 2 mm particle size which resulted in 23 % higher methane yield (0.22 m 3 kg -1 VS) compared to untreated sisal fibres (0.18 m 3 kg -1 VS). Liu et al 69 conducted steam explosion pretreatment of corn stover with particle sizes at 2.5, 2.0, 1.5, 1.0, and 0.5 cm in order to improve its enzymatic digestibility. The results showed a higher amount of byproducts and lower sugar recoveries for the larger biomass particles (2.5 cm) during pretreatment, while sugar conversions and yields were higher during enzymatic hydrolysis.…”

Biomass availability is one of the key factors for biogas production in the future. The current status and possibilities for utilizing harvest residues (soybean straw, corn stover and sunflower stalk) in Croatia for biogas production is given. In the last few decades, different pretreatment methods have been developed for the degradation of different lignocellulosic biomass, but many of them are environmentally unfriendly and sometimes very expensive. More research and development is necessary in order to find both economically and environmentally friendly pretreatment methods. This paper provides a review on the mechanical, physical, and biological methods used for different lignocellulose material pretreatment. Harvest residues are usually left in the field, but with the improvement of the pretreatment process along with soil protection, they could be used for the production of huge amounts of energy in the future.

“…New technologies have been developed to enhance the process of biomass accessibility. Among them, there are processes involving supercritical fluids (Okajima and Sako, 2014), acid or alkaline treatments (Cabrera et al, 2014;Moe et al, 2012), steam explosion (Liu et al, 2013) and high-intensity ultrasound (Villa-Vélez et al, 2015b).…”

-The benefits of high-intensity ultrasound in diverse processes have stimulated many studies based on biomass pretreatment. In order to improve processes involving ultrasound, a calorimetric method has been widely used to measure the real power absorbed by the material as well as the cavitation effects. Peanut shells, a byproduct of peanut processing, were immersed in acidified aqueous solutions and submitted to an ultrasonic field. Acoustic power absorbed, acoustic intensity and power yield were obtained through specific heat determination and experimental data were modeled in different conditions. Specific heat values ranged from 3537.0 to 4190.6 J·kg -1 ·K -1 , with lower values encountered for more concentrated biomass suspensions. The acoustic power transmitted and acoustic intensity varied linearly with the applied power and quadratically with solids concentration, reaching maximum values at higher applied nominal power and for less concentrated suspensions. A power yield of 82.7% was reached for dilute suspensions at 320 W, while 6.4% efficiency was observed for a concentrated suspension at low input energy (80 W).

“…Beside the desired improved enzyme accessibility and subsequently the increased sugar yield, this process also causes a significant mass loss. This was observed in numerous studies on various substrates [16][17][18][19]. Another effect is the liberation of toxic degradation products during pretreatment and their accumulation in the hydrolysates.…”

Corn cobs are a promising lignocellulosic substrate for the production of biofuels like bioethanol via conventional yeast or biodiesel via oleaginous yeast. Pretreatment of the substrate is essential for further hydrolysis and fermentation steps. This study focused on the steam explosion method as pretreatment. Therefore, different steam explosion severities were evaluated. (untreated) to a maximum of 214.9 g·kg -1 dry matter (190 °C/30 min). Furthermore, the mass recovery was calculated. At harsher pretreatment conditions, a significant mass loss was observed, estimated by the ash content in the recovered dry matter. The lowest recovery rate was observed for SF = 4.13 (190 °C/30 min) with 68.39%. The produced inhibitors were evaluated.
