“…The low content of lignin in Miscanthus × giganteus and its conceptual distinction from wood lignin [ 18 ], along with the high cellulose content (up to 55.5%), allow this crop to be reckoned as a feedstock for the manufacture of an array of valuable products. Moreover, based on the chemical composition measurements of Miscanthus that is a new cellulosic source for Russia, it can be concluded that Miscanthus has a lead position among other non-woody species, as reported likewise in [ 36 , 49 , 50 , 51 , 52 , 53 , 54 ].…”

Lignocellulosic biomass is of great interest as an alternative energy resource because it offers a range of merits. Miscanthus × giganteus is a lignocellulosic feedstock of special interest, as it combines a high biomass productivity with a low environmental impact, including CO2 emission control. The chemical composition of lignocellulose determines the application potential for efficient industrial processing. Here, we compiled a sample collection of Miscanthus × giganteus that had been cultivated in different climate regions between 2019 and 2021. The chemical composition was quantified by the conventional wet methods. The findings were compared with each other and with the known data. Starting as soon as the first vegetation year, Miscanthus was shown to feature the following chemical composition: 43.2–55.5% cellulose content, 17.1–25.1% acid-insoluble lignin content, 17.9–22.9% pentosan content, 0.90–2.95% ash content, and 0.3–1.2% extractives. The habitat and the surrounding environment were discovered herein to affect the chemical composition of Miscanthus. The stem part of Miscanthus was found to be richer in cellulose than the leaf (48.4–54.9% vs. 47.2–48.9%, respectively), regardless of the planation age and habitat. The obtained findings broaden the investigative geography of the chemical composition of Miscanthus and corroborate the high value of Miscanthus for industrial conversion thereof into cellulosic products worldwide.

Lignocellulosic biomass represents the most abundant renewable material in the world, whereas agricultural residues, including those from maize cultivation, comprise a significant fraction of the total plant waste that can be repurposed for various applications. Lignocellulosic feedstocks are non-edible and consist mainly of: cellulose, hemicellulose, and lignin, along with extractive compounds. Pretreatment is required to separate the lignocellulosic biomass into its constituents for efficient utilization. Even after extensive research and development of numerous techniques, pretreatment remains one of the most expensive phases in converting lignocellulosic biomass into biobased products.

“…Within the latter group, perennial grasses have emerged as potential raw materials for biorefineries with the aim of the sustainable production of renewable fuels and chemicals via thermo-chemical conversion [ 11 ], with the advantage that they do not compete with food crops [ 56 ]. Miscanthus is a non-invasive perennial grass that is able to grow with a remarkable productivity (15–25 tons of dry matter/ha) and with little or no herbicide or nitrogen requirements [ 20 ], good tolerance to temperature, and high yield/energy content [ 57 ]; thus, it exhibits great potential as a feedstock for conversion into biobased products in integrated biorefineries [ 2 ].…”

Effects of Hydrothermal Processing on Miscanthus × giganteus Polysaccharides: A Kinetic Assessment

Miscanthus × giganteus samples were characterized for composition and treated with hot compressed water (hydrothermal or autohydrolysis treatments) at temperatures in the range of 190–240 °C. The liquid phases from treatments were analyzed to assess the breakdown of susceptible polysaccharides into a scope of soluble intermediates and reaction products. The experimental concentration profiles determined for the target compounds (monosaccharides, higher saccharides, acetic acid and sugar-decomposition products) were interpreted using a pseudohomogeneous kinetic mechanism involving 27 reactions, which were governed by kinetic coefficients showing an Arrhenius-type temperature dependence. The corresponding activation energies were calculated and compared with data from the literature. The kinetic equations allowed a quantitative assessment of the experimental results, providing key information for process simulation and evaluation.
