HIGHLIGHTSThis article fully discusses the recent trends in the production of one the most attractive types of biofuels, i.e., biodiesel.with a focus on the existing obstacles for its large scale production. Moreover, recent innovations/improvements under three categories of upstream, mainstream, and downstream processes are also presented. Upstream strategies are mainly focused on seeking more sustainable oil feedstocks and/or enhancing the quality of waste-oriented ones. The mainstream strategies section highlights the numerous attempts made to enhance agitation efficiency including chemical and/or mechanical strategies. Finally, the innovative downstream strategies basically dealing with 1) separation of biodiesel and glycerin, 2) purification of biodiesel and glycerin, and 3) improving the characteristics of the produced fuel, are comprehensively reviewed.

“…This is based on determining the time needed for a given volume of fluid passing between two points marked on the instrument. The kinematic viscosity is given by the ratio between the dynamic viscosity (h, in Poise, g/cm s) and the density (r, in g/cm 3 ) υ = h/r (in cm 2 /s or centistokes (cSt), mm 2 /s). Samples, previously centrifuged at 3,500 rpm for 10 min and filtered at 50°C, are immersed in a thermostatic bath at 40°C for 15 min, making sure that the temperature is stable.…”

Background: Novozym 435, a commercial lipase from Candida antarctica, recombinant, expressed in Aspergillus niger, immobilized on macroporous acrylic resin, has been already described in the obtention of biodiesel. It is here evaluated in the production of a new biofuel that integrates the glycerol as monoglyceride (MG) together with two fatty acid ethyl esters (FAEE) molecules by the application of 1,3-selective lipases in the ethanolysis reaction of sunflower oil.

“…In the last few years, biodiesel has been put forth as an environmental friendly alternative to the large volume of petro-based diesel burnt daily (Oh et al, 2012). Biodiesel also known as fatty acid methyl or ethyl ester could be derived from vegetable oils, animal fats as well as waste cooking oil (WCO) through a number of methods and in particular transesterification reaction (Leung et al, 2010;Talebian-Kiakalaieh et al, 2013).…”

HIGHLIGHTS Standard-quality biodiesel was obtained using the proposed strategy.Up to 15% less water consumption after two rounds of biodiesel production operations. GRAPHICAL ABSTRACT Strengthening the environmental-friendly aspects of biodiesel production process. Jaber et al. / Biofuel Research Journal 5 (2015) 148-151 Please cite this article as: Jaber R., Shirazi M.M.A., Toufaily J., Hamieh A.T., Noureddin A., Ghanavati H., Ghaffari A., Zenouzi A., Karout A., Ismail A.F., Tabatabaei M. Biodiesel washwater reuse using microfiltration: toward zero-discharge strategy for cleaner and economized biodiesel production. A simple but economically feasible refining method to treat and re-use biodiesel wash-water was developed. In detail, microfiltration (MF) through depth-filtration configuration was used in different hybrid modules. Then, the treated wash-water was mixed with clean water at different ratios, re-used for biodiesel purification and water-washing efficiency was evaluated based on methyl ester purity analysis. The findings of the present study revealed that depth-filtration-based MF combined with sand filtration/activated carbon separation and 70% dilution rate with fresh water not only achieved standard-quality biodiesel product but also led to up to 15% less water consumption after two rounds of production operations. This would be translated into a considerable reduction in the total volume of fresh water used during the operation process and would also strengthen the environmental-friendly aspects of the biodiesel production process for wastewater generation was obviously cut by the same rate as well. 
