Crude glycerol, a by-product of biodiesel industry, has been used for production and polyhydroxy-alkanoates. But question is: which product is economically favorable using crude glycerol as substrate? In this study, energy balance economic assessment carried out valorization B10 polyhydroxy-butyrate (PHB) production. For same quantity utilized, ratio was higher than PHB while unit cost lower th...

As an inevitable by-product of the biofuel industry, glycerol is becoming an attractive feedstock for biorefinery due to its abundance, low price and high degree of reduction. Converting crude glycerol into value-added products is important to increase the economic viability of the biofuel industry. Metabolic engineering of industrial strains to improve its performance and to enlarge the produc...

Increased cost of common feedstuffs and increased availability of coproducts from plant-based biofuel manufacturing has enhanced interest in the use of these coproducts in rations for dairy cattle (Donkin and Doane, 2007). Glycerol (commonly marketed as crude glycerine with a glycerol content of approximately 80%) is a coproduct produced during biodiesel production from soybean oil and is becom...

Glycerine (glycerol) is a polyol consisting of three carbon atoms bonded to hydroxyl groups. It by-product the transesterification triglycerides, such as animal fats, vegetable oils, or used cooking oils during biodiesel production process. Crude glycerine subject purification processes resulting in distilled containing at least 99.5% glycerol. Currently, produced high-quality food, pharmaceuti...

Conversion of glycerol from biodiesel production to glycerol carbonate was studied by esterification with dimethyl carbonate in a non-catalytic supercritical condition. It was found that in a non-catalytic supercritical condition, glycerol at higher purity gave higher yield of glycerol carbonate at 98 wt% after reaction at 300 °C/20-40 MPa/15 min. The yield of glycerol carbonate was observed to...

A new application for glycerol that expands its possibilities apart from green solvent and precursor of value-added products has been demonstrated. Simple, easily available, and environmentally friendly dioxomolybdenum(VI) complexes are highly efficient catalysts for the chemoselective sulfoxide deoxygenation with this biomass-derived chemical feedstock. Both refined glycerol and crude glycerin 10
