New trends on crude glycerol purification: A review
Fuel, 2023 The increasing effort of the global community to reduce dependency on fossil fuels led to an increase in the production of biodiesel and therefore the oversupply of crude glycerol. Different steps are necessary to ensure this oversupply of highly impure, waste-based crude glycerol (approximately 680,000 tonnes by 2024) can be made suitable for ...

A review on variation in crude glycerol composition, bio-valorization of crude and purified glycerol as carbon source for lipid production [PDF]
Bioresource Technology, 2019 Crude glycerol (CG) is a by-product formed during the trans-esterification reaction for biodiesel production. Although crude glycerol is considered a waste stream of the biodiesel industry, it can replace expensive carbon substrates required for lipid production by oleaginous micro-organisms.

The Use of Crude Glycerol as a Co-Substrate for Anaerobic Digestion. [PDF]
MoleculesOne of the most interesting applications of crude glycerol (CG) is its use for biogas production via the anaerobic co-digestion (AcoD) process. The main aim of the current study was to provide a comprehensive review on the performance of the AcoD of CG mixed with various substrates. For this purpose, analyses were performed for studies available in the
