Due to the global depletion of natural resources, developing economically and environmentally sustainable energy sources is critical. Biodiesel can substitute for diesel without significant modification of existing engines. Biodiesel production has accelerated in recent years, because of aggressive government policies and incentives to meet energy demand and environmental concerns. A surplus amount of glycerol (Gly) is generated during biodiesel production as a byproduct. Thus, developing viable routes for the valorization of Glyl is crucial for the sustainability of the biodiesel industry. Valorization of Gly-to-glycerol carbonate (Glc) is considered an attractive route due to its wide industrial applicability. This paper discusses the potential synthesis routes including glycerolysis of urea, direct carbonation of Gly with CO 2 , enzymatic transesterification of Gly, and catalytic transesterification of Gly with alkyl carbonate to produce Glc. This paper addresses the performance of various homogeneous and heterogeneous catalysts used in Glc synthesis. Among various synthesis routes, catalytic transesterification of Gly with dimethyl carbonate (DMC) is considered as green and environmentally friendly, operates under mild reaction conditions, and is an industrially feasible process with high selectivity and yield. In order to achieve high yield and selectivity of Glc, key influencing process parameters such as catalyst dose, molar ratio of DMC/Gly, reaction temperature, reaction time, and basic sites of the catalyst are discussed. Repurposing of surplus glycerol for Glc production enhances biodiesel economics. Finally, this paper suggests future prospects for various pathways for the sustainable production of Glc.

Herein, we report a base‐catalyzed transesterification reaction of glycerol, a waste product of the biodiesel industry, with various dialkyl carbonates, which act both as reactants and solvents, to convert glycerol carbonate into an industrially useful molecular building block. The catalyst, being used for the first time, is also a waste product from industry, present in bauxite residues and in the Portland cement, simply known as tricalcium aluminate. Despite being well‐known and readily available, this solid is only extremely poorly researched catalyst, nevertheless, using dimethyl and diethyl carbonate, glycerol conversion rates >80% and glycerol carbonate yields >60% could be achieved in just 1 hour (under air atmosphere, and reflux). In a comparison of the performance with other catalysts commonly researched today, as well as with other components of red mud and cements, the results showed that tricalcium aluminate is excellent, cheap and largely environmentally friendly material for this purpose. Reusability studies of the catalysts have also shown that they provide high conversion and product yields even after repeated use, although different material characterization techniques showed intense glycerol‐catalyst surface interaction and intermediate product formation, the deactivating side effects of which could be avoided by catalyst regeneration steps.
