A roadmap for renewable C2–C3 glycols production: a process engineering approach

Abstract

A review of strategies and challenges for chemical and biochemical production and purification of C2–C3 glycols from renewable sources.

Valorisation of glycerol through catalytic hydrogenolysis routes for sustainable production of value-added C3 chemicals: current and future trends

“…101 In contrast, this technique is non-environmentally friendly and gives a low yield of production. 102 In 2019, the global market size of 1,3-PDO exceeded USD 490 million, which was approximately two-thirds that of conventional PTT production. 103 Thus, an emerging bio-based 1,3-PDO from a renewable source, specifically glycerol, is enticing and profitable.…”

Engineering Escherichia Coli for the Utilization of Ethylene Glycol

“…Among the various substrates and products that we evaluated, we identi ed that ethylene glycol (EG) was a highly promising substrate for orthogonal production of a variety of chemicals because it minimized the interactions between biomass and chemical producing pathways. Today, EG is produced primarily by the petrochemical industry from ethylene, however, renewable alternatives are currently in the early stages of development (31,32). In particular, EG can be produced from the electrochemical conversion of CO 2 (11,13), as well as from the chemocatalytic conversion of cellulosic materials and glycerol (a common waste in industrial biofuel and soap production) (31,32).…”

Today, EG is produced primarily by the petrochemical industry from ethylene, however, renewable alternatives are currently in the early stages of development [11,12]. In particular, EG can be produced from the electrochemical conversion of CO 2 [13,14], from the chemocatalytic conversion of cellulosic materials and glycerol (a common waste in industrial biofuel and soap production) [11,12], as well as from the depolymerization of poly(ethylene terephthalate) (PET) plastic (an abundant waste material) to its monomers [15][16][17][18].…”
