A potential degrader of paraffinic and aromatic hydrocarbons was isolated from oil-contaminated soil from steel plant effluent area in Burnpur, India. The strain was investigated for degradation of waste lubricants (waste engine oil and waste transformer oil) that often contain EPA (Environmental Protection Agency, USA) classified priority pollutants and was identified as Ochrobactrum sp. C1 by...

Recently, the application of lipase enzyme as biocatalyst in conversion waste cooking oil (WCO) to free fatty acids and glycerol has been trending well. Therefore, present study attempts use WCO which is found abundance Malaysia substrate for halal microbial can be exploited food industry. The workability conversion, however suffers severely due potential denaturation extended reaction time. Th...

Abstract Mesoporous, bifunctional MgO-SnO 2 nanocatalysts with enhanced surface area are used for producing biodiesel from waste cooking oil. Biodiesel yield of 80% is achieved within the first 20 min when transesterification carried out at an optimum condition 18:1 methanol to oil ratio, wt% nanocatalyst, and a reaction temperature 60 °C. The conversion gives maximum 88% allowed continue 120 m...

The recyclability of waste cooking oil (WCO) as rejuvenator for aged asphalt mixture improved the serviceability pavement itself. Currently, researcher is exploring new potential WCO modifier binder modification. However, issue compatibility properties in modification with arises since poor mechanical performance globally recorded thus reflected weakness adhesion bonding inside material. Basica...

In order to produce biodiesel from waste cooking oil and optimize its yield, a two-stage process of esterification/ transesterification has been used in this study. First, we used the acidic catalysts H2SO4 in order to diminish the content of free fatty acid (FFA) in oil that caused reducing the oil acidity from 6.1% to 0.57% through esterification. Then, the biodiesel was produced by transeste...

Waste cooking oil (WCO) was used as a potential feedstock for biodiesel production. High levels of free fatty acids (9.85% w/w) in WCO made it an undesirable substrate for direct transesterification reaction. To solve this issue, a two-step process was implemented in this research. Firstly, esterification reaction was performed in presence of sulfuric acid as a common acid catalyst to reduce th...
