“…The OPEFB has been used traditionally as source of heat and power in incinerators of palm oil mills, causing environmental pollution (Cotana et al, 2014). Nevertheless, OPEFB can serve as a renewable source of sugar and lignin, available in large amounts and at relatively low costs for chemical and fuels, through the biorefinery approach (Wildschut et al, 2013 In a biorefinery, the lignin can be converted to high-value-added chemicals such as, resin precursors, antioxidants, antimicrobial agents, aromatics compounds, synthetics alcohols, Fisher-Tropsch liquid fuel, syngas, and molecules of high and low molecular weight, which can be profitable.…”

“…This determined an enrichment in the cellulose, which was not even degraded by harsher conditions. As demonstrated by other studies [14,30], SE does not affect the lignin fraction, causing an enrichment in its percentage into the WIS.…”

This paper builds upon a research project funded by the Italian Ministry of Environment, and aims to recover stranded driftwood residues (SDRs), in order to transform a potential pollution and safety issue into valuable bio-resources. In particular, one of the experiments consisted of bioethanol production from lignocellulosic residues. The SDRs were gathered from the Italian coast (Abruzzo Region, Italy) after an intense storm. The biomass recalcitrance, due to its lignocellulosic structure, was reduced by a steam explosion (SE) pretreatment process. Four different pretreatment severity factors (R 0 ) were tested (LogR 0 3.65, 4.05, 4.24 and 4.64) in order to evaluate the pretreated material's accessibility to enzymatic attack and the holocellulose (cellulose plus hemicellulose) recovery. A first enzymatic hydrolysis was performed on the pretreated materials by employing a solid/liquid (S/L) ratio of 1% (w/w) and an enzyme dosage of 30% (w enzyme/w cellulose), in order to estimate the maximum enzymatically accessible cellulose content. Since the primary goal of pretreatment and hydrolysis is to convert as much cellulose as possible into monomeric glucose and recover all the holocellulose, the two pretreated materials showing these features were selected for bioethanol production process. The pretreated materials underwent a semi-simultaneous saccharification and fermentation (SSSF). The SSSF process was performed into two lab-scale bioreactors (5 L) with an S/L ratio of 15% and an enzyme dosage of 15% for five days. The efficiency of the whole bioethanol production process was assessed as ethanol overall yields (g ethanol/100 g raw material). The best overall yield was achieved by sample BS04 (8.98 g ethanol/100 g raw material).

“…However, in most of these processes the residual lignin is often burnt as a low grade fuel for power generation or steam production or used as low value products such as dispersing, binding or emulsifying agents, phenolic resins, carbon fibres, wood panel products, automotive brakes and epoxy resins [7,14]. Lignin is of particular interest because it contains several highly functionalised aromatic moieties.…”
