“…For instance, combustion, gasification, and pyrolysis are known as the main thermochemical conversion pathways, while fermentation and anaerobic digestion are the most common biochemical conversion pathways. The crude glycerol utilization in microbial fermentation has been studied extensively and many excellent reviews have been published in the last 15 years, and can be referred to for further information (25)(26)(27)60,61).…”

Biodiesel being one of the most promising renewable biofuels has seen rapid increase in production capacity due to high demand for diesel replacement; along with oversupply of its by-product, crude glycerol. Developing new industrial usage for glycerol is essential to defray the cost and sustainability of biodiesel industry and to promote the biodiesel industrialization. One of the approaches is by the transformation of glycerol into a liquid, referred as bio-oil through pyrolysis technology. Bio-oils produced by pyrolysis processes can be upgraded to produce transportation fuels or for power generation. However, current state of pyrolysis technologies are still major hurdles their development with respect to its commercial applications. Recently, microwave technology has attracted considerable attention as effective method for significantly reducing reaction time, improving the yields and selectivity of target products. Hence, this review strives extensively towards addressing the application of microwave-assisted technology applied to the pyrolysis process as a way of cost-effective and operationally feasible processes to directly utilize crude glycerol. The present review will focus on the pyrolyzed liquid product (bio-oil) derived by employing the microwave-assisted pyrolysis method. This review concludes that microwaveassisted glycerol conversion technology is a promising option as an alternative method to conventional glycerol conversion technology.

“…From 2004 to 2008, the global production of crude glycerol from biodiesel conversion increased from 200 thousand tonnes to 1.224 million tonnes [2,19] in 2005, the global market for purified glycerol was anticipated to be over 900,000 tonnes [53]. This provided a chance for scientists to discover new uses for refined and crude glycerol.…”

Globally, there is a climate change due to greenhouse gases, hence the production processes for chemicals should comply with green chemistry principles to decrease the impact it has on the climate. This book chapter focuses on the catalytic production of glycerol, which is a platform chemical that is widely used in the manufacture of various industrially important chemicals and derivatives, namely 2,3-dihydroxypropanal, glycerol ether, glycerol ester, acrolein, 1,2-propanediol and glycidol. The literature reviewed compares the production of glycerol using homogeneous and heterogeneous catalysts, to determine efficient and environmentally benign glycerol catalysts and to study glycerol as a platform chemical and its value in application.

“…The fermentation is by the conversion of DHAP mediated pathways: The oxidative pathway is catalyzed by glycerol dehydrogenase and dihydroxyacetone kinase enzyme and the reductive pathway is catalyzed by glycerol 3-phosphate dehydrogenase and kinase [86,87] . A non pathogenic strain of E. coli (ATCC 11505) under anaerobic condition is capable of withstanding high concentration of glycerol and resists glycerol inhibition [88] . Strains of Pachysolen species of yeast are also capable of producing ethanol under aerobic conditions immobilized in polycryogel that resulted in 90% yield [89] .…”

Crude glycerol is produced as a by-product from biodiesel production via trans-esterification with methanol and this process accounts for 10% (w/w) of the total biodiesel produced worldwide. The glyc- erol glut created can be utilized to increase biodiesel profitability since disposal can pose a threat to the environment. The need is to transform this surplus crude glycerol into added-value products. Biological based conversions are efficient in providing products that are drop-in replacements for petro-chemicals and offer functionality advantage, commanding higher price with the potential to increase bio-refinery revenue. Glycerol is a stable and multifunctional compound used as a building block in fine chemical synthesis like bio-polymers, polyunsaturated fatty acids, ethanol, hydrogen, n -butanol, glycerol carbonate, glycerol acetyl esters etc. Bio-catalysts add higher value to bio based products by catalyzing not only their selective modification, but also their synthesis under controlled and mild conditions. This article focuses on different bioconversion technologies of crude-glycerol to value added industrial products –obtained as waste from current bio-diesel production. We abridge the recent relevant approach for the production of various platform chemicals from bio-glycerol over enzyme and chemical catalysts.
