“…Research divulged in April 2019 by Potsdam Institute for Climate Impact Research, conducted by Willeit et al [1], reports alarming data concerning climate changes that are occurring on our planet: carbon dioxide, one of the combustion gases responsible for global warming, is at the highest concentration level ever recorded in 3 million years, which makes it inevitable to raise of the Earth's temperature and the level of the oceans. The use of fossil fuels, such as petroleum diesel, has a considerable share of these emissions responsible for promoting the pollution of our ecosystem [2,3]. In addition, the current reserves of nonrenewable fossil fuels are depleting each day.…”

Enzymatic synthesis of biodiesel showed advantageous characteristics in relation to other technologies once it works under bland conditions, no generation of wastewater, no occurrence of saponifications reactions and production of a biodiesel with high quality. Although many researches still apply immobilized lipases, the high costs associated with this biocatalyst hamper the economic viability of the process. Lipases in free/soluble/liquid formulation employed to biodiesel production via hydroesterification reaction have attracted interest from researchers because they are more cost effective than the immobilized form, making the enzymatic route more competitive. In addition, soluble lipases present higher reaction rates, reducing the time required to obtain a satisfactory biodiesel yield. Despite the fact that already exist industrial plants producing biodiesel with the assistance of lipases in liquid formulation, results of researches show that the process still needs to overcome some drawbacks. This paper is a comprehensive and critical discussion on the publications where soluble lipases were applied on biodiesel synthesis, as well as the challenges that the technology faces and its current status in pilot and industrial applications.

“…By this way, the environmental costs can be calculated. The aim of this method is to investigate the economic aspects of environmental aspects and the cost of environmental impact of CO2 [19]. The cost of CO2 was determined to be CO 2 C = 0.0327 $/kg [20].…”

“…However, exhaust emissions are more susceptible compared to other parameters for changes of TPO ratio in blends. Yildiz et al [19] presented environmental pollution cost analysis with combining economic and environmental parameters. They compared biodiesel and diesel fuel usage for diesel engines with considering this analysis and reported that the diesel fuel usage for diesel engine is slightly better option than biodiesel fuel in terms of environmental pollution cost analysis for better environmental management.…”

The utilization of waste cooking oil (WCO) and bleached palm oil (BPO) for the production of biodiesel in the presence of hydrothermally treated calcium oxide (CaO) derived from waste chicken eggshells was investigated. Waste chicken eggshells were calcined at 850 °C and then hydrothermally treated at 120 and 140 °C to produce two sets of CaO catalysts. Hydrothermal treatment of the catalysts resulted in a decrease of the crystallite size from 47 to 30 and 28 nm at temperatures of 120 and 140 °C. The catalytic performance of the CaO catalysts was evaluated with WCO and BPO, respectively. WCO gave biodiesel yields of 82.7 and 83.1 % for CaO catalysts aged at 120 and 140 °C respectively. BPO gave 79.4 and 79.6 % yields, respectively, for the same set of catalysts.
