“…This is largely due to a high proportion of microbial convertible carbohydrates exist in the green wastes. For example, the woody waste consists of about 70% (dried weight percentage) polysaccharides (cellulose and hemicellulose) and 25e35% lignin, and lignin covers the polysaccharides that are substrate convertible into fuel materials by enzymes or/and microorganisms [112]. However, it is hard to convert directly green wastes into hydrogen by anaerobic fermentative microorganisms because of their complex composition and polymeric structure.…”

“…Moreover, the pretreatment led to conversion of 80 % of the holocellulose into methane. Similarly, a considerable improvement was observed in a study performed by Take et al (2006) who applied steam explosion treatment on wood (Japanese cedar chips), prior to biogas production. The pretreatment was performed at 4.51 MPa (258°C) for 5 min.…”

Methane production via anaerobic digestion is a steadily growing industry in Europe and all over the world. Biomethane reduces the demand for fossil fuels, since it can be used for the production of power and heat or converted to vehicle fuel. Anaerobic digestion is a renewable energy technology; however, it can also be considered as a low-cost environmental-friendly waste management process, since it reduces the emission of greenhouse gases (GHGs), while it stabilizes the wastes. Currently, mainly the organic fraction of household waste, food waste, sewage sludge, manure, and energy crops is used for biogas production; nevertheless, there are a wide range of other organic substrates which can be utilized for biogas production. Among the organic matters, lignocellulosic materials have a great potential. Great abundance worldwide and carbohydrate-rich contents make them an attractive feedstock for biofuel production. Currently, anaerobic digestion of energy crops is widespread; however, biogas production from lignocellulosic residuals and wastes is still under investigation. This chapter focuses on anaerobic digestion of lignocellulosic materials. It explains the anaerobic digestion process and the current technologies used for crops digestion. It also summarizes the biogas potential of different lignocellulosic materials and the latest research on pretreatments to improve the methane yield. Finally, this chapter compares anaerobic digestion of lignocellulosic materials with energy production from these kinds of materials through thermochemical processes.

“…After the saturated steam exposure, a ball valve at the bottom of the reactor was opened suddenly to bring the reactor rapidly to atmospheric pressure. This yielded the product, containing liquid and solid materials (Take et al, 2006). The exploded material was recovered in a cyclone and after cooling to about 40°C filtered for solid recovery.…”

The steam explosion-chemical pretreatment is a more effective wood pretreatment technique than the conventional physical pretreatment by accelerating reactions during the pretreatment process. In this paper, two-stage pretreatment processes of hardwood were investigated for its enzymatic hydrolysis and the succinic acid yield from the pretreated solid. The first stage pretreatment was performed under conditions of low severity to optimize the amount of solid recovery. In the second stage pretreatment washed solid material from the first stage pretreatment step was impregnated again with chemical (alkaline or chlorinebased chemicals) to remove a portion of the lignin, and to make the cellulose more accessible to enzymatic attack. The effects of pretreatment were assessed by enzymatic hydrolysis and fermentation, after the two stage pretreatments. Maximum succinic acid yield (16.1 g L -1 and 77.5%) was obtained when the two stage pretreatments were performed at steam explosion -3% KOH.
