Mar 14, 2012· Biodiesel is a promising alternative, and renewable, fuel. As its production increases, so does production of the principle co-product, crude glycerol. The effective utilization of crude glycerol will contribute to the viability of biodiesel. In this review, composition and quality factors of crude glycerol are discussed. The value-added utilization opportunities of crude glycerol are reviewed.
Glycerol is successfully converted by the chemical industry into C3-monomers, which are then used to make valued polymers or directly used to produce formulations in high demand. The said monomers include epichlorohydrin used to make epoxy thermoset resins, 1,2-propanediol (mono propylene glycol) for deicing formulations and 1,3-propanediol

Glycerol (/ ˈ ɡ l ɪ s ə r ɒ l /; also called glycerine or glycerin) is a simple polyol compound. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic. The glycerol backbone is found in those lipids known as glycerides.Due to having antimicrobial and antiviral properties it is widely used
Practical steps for responding to the coronavirus crisis. The COVID-19 pandemic and its attendant effect on markets and commercial activity is presenting a range of challenges to the engineering and construction (E&C) industry — challenges that could deepen depending on the severity and length of the crisis in the US and globally.
