“…The purification process is energy intensive and further adds to the economic stress of biodiesel production. In 2019, the price of crude glycerol plummeted to $170/t while purified glycerol was traded at an average of $895/ton . Significant attention has been drawn to synthesizing value added chemicals from crude glycerol via different catalytic (oxidation, dehydration, dehydrogenation, etc.)…”

Here we present an approach for developing the next generation of bio(meth)acrylates using glycerol ketals as a platform for property differentiation. Crude glycerol, a biodiesel byproduct, and ketones, derived from biomass valorization, are the building blocks for these polymeric materials. Biobased materials are witnessing a prominent boom in research and commercialization due to increased awareness about the carbon footprint and depletion of petroleum resources. Biodiesel and biopolymers are major linchpins to improve sustainable energy and material needs of the world in the coming years. Glycerol ketal (meth)acrylate monomers synthesized by the reaction of glycerol and various ketones consist 65-74 wt.% bioderived content. Glycerol ketals from different ketones used in our study (acetone, cyclopentanone and butanone) are the pendant groups on the (meth)acrylate polymer backbone. We studied the effect of various pendant side-chain ketal groups on the thermal and rheological properties of 1 these polymers. The methacrylate polymers had a higher glass transition temperature (T g ) (8-40 • C) while the acrylate derivatives had much lower T g between -11 • C to 2 • C. The side chain group on these polymers offers us a robust knob to tune the thermal properties (e.g. T g ) and rheological properties (e.g. modulus and entanglement behaviour) for varied applications such as hard block polymers and adhesives.

“…Crude glycerol, a major byproduct of the biodiesel process in the transesterification of animal fats and vegetable oils, has been widely examined for waste conversion to produce value-added chemicals [1,2]. During every 9 kg of biodiesel synthesis, approximately 1 kg of crude glycerol is produced as a byproduct.…”

“…Although several successful glycerol conversion studies have been reported, further improvement is still required because of the relatively high purification cost [4]. Pure glycerol costs 7.5 times more than its crude counterpart at the current market price (Table 1) [2,5]; this implies that the additional glycerol purification process is complicated and expensive. Therefore, several studies have reported direct bioconversion of nonpurified crude glycerol to value-added products, such as hydrogen, methane, fatty acids, and 1,3-propanediol [6][7][8][9][10][11].…”

Bioconversion of Crude Glycerol into 1,3-Propanediol(1,3-PDO) with Bioelectrochemical System and Zero-Valent Iron Using Klebsiella pneumoniae L17

Crude glycerol is a major byproduct in the production of biodiesel and contains a large number of impurities. The transformation of crude glycerol into valuable compounds such as 1,3-propanediol (1,3-PDO) using clean and renewable processes, like bioconversion, is an important task for the future of the chemical industry. In this study, 1,3-PDO bioproductions from crude and pure glycerol were estimated as 15.4 ± 0.8 and 11.4 ± 0.1 mmol/L, respectively. Because 1,3-PDO is a reductive metabolite that requires additional reducing energy, external supplements of electron for further improvement of 1,3-PDO biosynthesis were attempted using a bioelectrochemical system (BES) or zero-valent iron (ZVI). The conversions of crude and pure glycerol under electrode and iron-based cultivation were investigated for 1,3-PDO production accompanied by metabolic shift and cell growth. The BES-based conversion produced 32.6 ± 0.6 mmol/L of 1,3-PDO with ZVI implementation.

Photoelectrochemical (PEC) catalysis provides the most promising avenue for producing value‐added chemicals and consumables from renewable precursors. Over the last decades, PEC catalysis, including reduction of renewable feedstock, oxidation of organics, and activation and functionalization of C‐C and C‐H bonds, are extensively investigated, opening new opportunities for employing the technology in upgrading readily available resources. However, several challenges still remain unsolved, hindering the commercialization of the process. This review offers an overview of PEC catalysis targeted at the synthesis of high‐value chemicals from sustainable precursors. First, we recall the fundamentals of evaluating PEC reactions in the context of value‐added product synthesis at both anode and cathode. Then, we highlight the common photoelectrode fabrication methods that have been employed to produce thin‐film photoelectrodes. Next, we systematically review and discuss the advancements in the PEC conversion of various feedstocks to produce highly valued chemicals. Finally, we present the challenges and prospects in the field. This review aims at facilitating further development of PEC technology for upgrading several renewable precursors to value‐added products and other pharmaceuticals.This article is protected by copyright.
