Applied Energy, 2013
The worldwide energy demand has been continuously increasing, thus requesting more sustainable alternatives to the rapidly depleting fossil fuels. Therefore, biofuels such as hydrogen, bioethanol and biodiesel are gaining more importance as a renewable and pollution-free solution, which might give a significant contribution to the future energy mix. In

Opportunities for the valorization of industrial glycerol via biotransformations
Current Opinion in Green and Sustainable Chemistry, 2021Industrial biotechnology faces the challenge of providing significant economic advantages using sustainable processes either to establish new processes, to displace established processes or valorize industrial waste. Crude glycerol obtained as a by-product of biodiesel production has very low market value but can be valorized via microbial ...

Industrial & Engineering Chemistry Research, 2013
The work reported in this article is a thermodynamic and kinetic study of the acetalization reaction between acetaldehyde and glycerol to produce glycerol ethyl acetal (GEA). A catalyst screening was performed allowing for the choice of Amberlyst-15 wet resin as the most suitable catalyst for this reaction.

Glycerol valorization: New biotechnological routes
Food and Bioproducts Processing, 2009Abstract Biodiesel have drawn attention in the last decade as a renewable, biodegradable, and non-toxic fuel. Raw glycerol can become an important feedstock when biodiesel is applied on a large commercial scale. With the production of 10 kg of biodiesel from rapeseed oil, 1 kg of glycerol becomes available.

Electrochemical Valorization of Glycerol via Electrocatalytic Reduction into Biofuels: A Review
ChemSusChem, 2023AbstractElectrochemical conversion of underutilized biomass‐based glycerol into high‐value‐added products provides a green approach for biomass and waste valorization. Plus, this approach offers an alternative to biofuel manufacturing procedure, under mild operating conditions, compared to the traditional thermochemical routes.

Abstract The present study explored the catalytic activity of the heterogeneous catalyst for transesterification of glycerol into glycerol carbonate, a versatile compound. Transesterification of glycerol was investigated with different active metals (Li, La, Ce, Mg, K) impregnated on MCM-41 (Mobil Composition of Matter No. 41) framework. Among these,

Heterogeneous catalysis for biodiesel synthesis and valorization of glycerol
Clean Technologies and Environmental Policy, 2014In the present work, heterogeneous catalysts in the synthesis of biodiesel, glycerol-based chemicals i.e., mono-glyceride, glycerol carbonate and di-methyl carbonate are explored. Use of heterogeneous catalysts can make the production process cost-effective and environment-friendly. We evaluated three catalysts viz.

Valorization of crude glycerol by microorganisms: A bibliographic and technological survey
Marine Pollution BulletinThe objective of this review was to investigate the current state of the development of biotechnological routes for the valorization of crude glycerol (CG) using microorganisms, through patent documents and scientific articles. The patents and articles were retrieved through combinations of the code C12N (microorganisms or enzymes), microalgae, and the
