Steam explosion as sustainable biomass pretreatment technique for biofuel production: Characteristics and challenges

Optimisation of recovery protein hydrolysate from chicken bone by steam explosion strategy and its calcium‐binding capacity and potential pro‐osteogenic activity

“…Vapocracking and explosive decompression are two phases in a thermophysicochemical process called steam explosion that produces mechanical degradation (Maniet et al, 2017). The steam explosion approach may be more advantageous than alternative treatment techniques in terms of cost, environmental friendliness, and energy use (Hoang et al, 2023;Wang et al, 2023). Steam explosion has frequently been used in plant biomaterials (lignocellulosic biomass, maize husk, and aspen wood) (Jacquet et al, 2015).…”

A guide to lignin valorization in biorefineries: traditional, recent, and forthcoming approaches to convert raw lignocellulose into valuable materials and chemicals

“…Steam explosion (SE) pretreatment is a particular type of hydrothermal pretreatment and one of the most common and effective pretreatment methods adopted for reducing the recalcitrance of lignocellulosic biomass toward enzymatic digestion. [124][125][126] In SE pretreatment, the biomass is initially contacted with saturated steam under elevated pressure and at high temperature (typically between 160 and 260 °C) for a short contact time (usually between 5 and 30 minutes) resulting in an initial swelling of lignocellulose structure. [125][126][127][128][129][130] Then a sudden decompression is realized, which causes the expansion of water inside biomass and the disruption of lignocellulose, with the creation of a porous structure.…”

“…82,127,133 Despite this, the low energy requirements, the absence of the use of expensive chemicals (with the associated recycling/ disposal cost), and the effective deconstruction of lignocellulose structure make SE pretreatment an attractive method for bioreneries. 124,125,134,135 3.2.3.

From waste to resource: advancements in sustainable lignin modification

“…Then, the pressure is released rapidly and the steam present in the biomass expands, causing fibers to break down. 13 This process is considered to be one of the most efficient and cost-effective, although it is important to note that it is often used as pretreatment of lignocellulosic biomass before other processes are applied, 26 and there is a large heterogeneity of the lignin obtained. 13 Hydrolysis lignin, on the other hand, is usually a by-product of bio-ethanol production from cellulose hydrolysis.…”
