Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

The Quality of Jerusalem Artichoke Biomass Harvested Twice during the Growing Season in North-Eastern Poland

Energies
Jerusalem artichoke (JA) (Helianthus tuberosus L., family Asteraceae) is an important feedstock for biofuel production due to its high biomass yield per unit area and the low costs associated with plantation establishment and cultivation technology.

Glycerol carbonate formation from glycerol and dimethyl carbonate using lithium‐based catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Excess glycerol from biodiesel production can be sustainably converted into value‐added products like glycerol carbonate, for its use in polymers, solvents, and as ecofriendly alternative as green chemical in various chemical industries. This study aims to synthesize a catalyst optimized for the glycerol and dimethyl carbonate (DMC) conversion

Alkali extraction and physicochemical characterization of hemicelluloses from young bamboo (Phyllostachys pubescens Mazel) [PDF]

BioResources, 2012
Two hemicellulose fractions were obtained by extraction of one-month- old young bamboo (Phyllostachys pubescens Mazel). The fractionation procedure employed 2% NaOH as extractant, followed by filtration, acidification, precipitation, and washing with 70%

The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate

ChemPhysChem, EarlyView.
Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...
