“…The calculated methane production, after subtraction of the methane produced from blank experiments was 62.44 ± 0.36 mL, corresponding to a BMP of 260.65 ± 0.04 L CH 4 /kg GL waste or 282.60 ± 0.04 L CH 4 /kg TS or 339.86 ± 0.05 L CH 4 /kg VS. The BMP of the GL waste used in the present study was comparable with that of ensiled meadow grass (372 ± 52 L CH 4 /kg) [8] and GL (402.5 L CH 4 /kg) [11], but higher than that of giant reed [22] or common reed [23] (188 L CH 4 /kg). In any case, the BMP of the untreated GL waste is higher than that of other lignocellulosic feedstocks and this could be attributed to the low lignin content, since the latter is negatively correlated to the BMP [24].…”

Biogas Production from Physicochemically Pretreated Grass Lawn Waste: Comparison of Different Process Schemes

Various pretreatment methods, such as thermal, alkaline and acid, were applied on grass lawn (GL) waste and the effect of each pretreatment method on the Biochemical Methane Potential was evaluated for two options, namely using the whole slurry resulting from pretreatment or the separate solid and liquid fractions obtained. In addition, the effect of each pretreatment on carbohydrate solubilization and lignocellulossic content fractionation (to cellulose, hemicellulose, lignin) was also evaluated. The experimental results showed that the methane yield was enhanced with alkaline pretreatment and, the higher the NaOH concentration (20 g/100 gTotal Solids (TS)), the higher was the methane yield observed (427.07 L CH4/kg Volatile Solids (VS), which was almost 25.7% higher than the BMP of the untreated GL). Comparing the BMP obtained under the two options, i.e., that of the whole pretreatment slurry with the sum of the BMPs of both fractions, it was found that direct anaerobic digestion without separation of the pretreated biomass was favored, in almost all cases. A preliminary energy balance and economic assessment indicated that the process could be sustainable, leading to a positive net heat energy only when using a more concentrated pretreated slurry (i.e., 20% organic loading), or when applying NaOH pretreatment at a lower chemical loading.

“…Extraction of the added value phenolic compounds from OMSW is technically and economically complex without carrying out a pretreatment process (Rubio-Senent et al, 2013b). Among the available pre-treatments, steam explosion treatment has been widely proposed as pre-treatment method for different fibrous waste such as swine slurry , reed biomass (Lizasoain et al, 2016), corncob (Zhang et al, 2017), and even OMSW Ortega-Martinez et al, 2016;Rincón et al, 2016). Steam explosion treatment involves high-temperature heating combined with a rapid pressure drop that physically disrupts the lignocellulosic structures turning them into soluble compounds (Capári et al, 2016;Zhou et al, 2016).…”

A promising source of high added value compounds is the Olive Mill Solid Waste (OMSW). The aim of this research was to evaluate the viability of a biorefinery approach to valorize OMSW through the combination of steam explosion, phenols extraction, and anaerobic digestion. Steam explosion treatment increased the total phenol content in the steam exploited OMSW, which was twice than that the total phenol content in raw OMSW, although some undesirable compounds were also formed. Phenol extraction allowed the recovery of 2098mg hydroxytyrosol per kg of OMSW. Anaerobic digestion allowed the partial stabilization of the different substrates, although it was not improved by the steam explosion treatment. The economic suitability of the proposed biorefinery approach is favorable up to a phenol extract price 90.7% lower than the referenced actual price of 520€/kg.

“…Previous studies have studied the effect of different pretreatment methods on the enhancement of the anaerobic digestion efficiency of lignocellulosic material. For example, methane production from reed which was pretreated with steam explosion was found to be increased by 89% (Lizasoain et al, 2016), while that of rice straw that was pretreated with fungus was observed to be increased by 78.3% (Mustafa et al, 2016). In general, the pretreatment methods utilized in biogas production can be classified into three different categories: physical, chemical, and biological (Wen et al, 2015).…”

Promotion of Biogasification Efficiency by Pretreatment and Bioaugmentation of Corn Straw with Microbial Consortium

To better understand the comparative effects between pretreatment and bioaugmentation methods on the promotion of corn straw biogasification efficiency, we analysed the cellulase activity, cellulose degradation rate, surface structure characteristics, and biogas production of corn straw that had been pretreated with aerobic microbial consortium (AMC). In addition, we also studied the effect of bioaugmentation using anaerobic microbial consortium (ANMC) on corn straw biogasification efficiency. The results from our study demonstrated that the cumulative methane generated from AMC and ANMC were 233.09 mL·g-1 VS and 242.56 mL·g-1 VS, which was increased compared to the control by 6.89% and 11.23%, respectively. We also observed that ANMC could also function to dramatically promote methane content during the anaerobic digestion of corn straw. This study demonstrated that AMC and ANMC were both able to promote the biogasification efficiency of corn straw, however, ANMC was found to perform better compared to AMC.
