Two-Step Purification of Glycerol as a Value Added by Product From the Biodiesel Production Process

Frontiers in Chemistry, 2019
For every ton of biodiesel produced, about 100 kg of glycerol is also generated as a by-product. The traditional method of removing glycerol is mainly by gravity separation or centrifugation.

Organic Carbonate Production Utilizing Crude Glycerol Derived as By-Product of Biodiesel Production: A Review

Energies, 2020
As a promising alternative renewable liquid fuel, biodiesel production has increased and eventually led to an increase in the production of its by-product, crude glycerol. The vast generation of glycerol has surpassed the market demand.

Preparation and Uses of Chlorinated Glycerol Derivatives

Molecules, 2020
Crude glycerol (C3H8O3) is a major by-product of biodiesel production from vegetable oils and animal fats. The increased biodiesel production in the last two decades has forced glycerol production up and prices down.

Effect of Adding Crude Glycerol Produced from Biodiesel Industry on Biogas Production from Anaerobic Digestion of Cattle Dung [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2018
Effect of crude glycerol addition to cattle dung on biogas generation and methane percentage was studied. Five percentages of crude glycerol were added to cattle dung during the anaerobic digestion process. The crude percentages ranged from 1 to 5% based

Changes in freshwater sediment microbial populations during fermentation of crude glycerol

Electronic Journal of Biotechnology, 2021
Background: This work studied how the exposure to an unusual substrate forced a change in microbial populations during anaerobic fermentation of crude glycerol, a by-product of biodiesel production, with freshwater sediment used as an inoculum.
