The Use of Biodiesel Residues for Heat Insulating Biobased Polyurethane Foams
International Journal of Polymer Science, 2017 The commercial and biobased polyurethane foams (PUF) were produced and characterized in this study. Commercial polyether polyol, crude glycerol, methanol-free crude glycerol, and pure glycerol were used as polyols.

Anaerobic digestion of crude glycerol: a review [PDF]
Environmental Technology Reviews, 2012 Several researchers have used crude glycerol as a source of substrate for methane production and power generation, which is a way of adding value to this residue that has a high chemical oxygen demand (COD) and is rich in impurities. This review article summarizes recent data and discussions on the use of crude glycerol as substrate and co-substrate ...

Glycerolysis of Glycerol Carbonate from Crude Glycerol for Synthesis of Polyurethane
Research Journal of Applied Sciences, Engineering and Technology, 2015 10% by weight of crude glycerol is produced during biofuel fermentation process, which has impacted the price of biofuel due to impurity content. In addition, the government’s regulations have prohibited the usage of crude glycerol as fuel source due to the emission of hazardous gases.

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
