Waste cooking oil (WCO) is a kind of non-edible oil with enormous quantities and its unreasonable dispose may generate negative impact on human life and environment. However, WCO is certainly a renewable feedstock of bio-based materials. To get the rebirth of WCO, we have established a facile and high-yield method to convert WCO to bio-based zwitterionic surfactants with excellent surface and i...

A comparative study of biodiesel production from waste cooking oil using sulfuric acid (Two-step) and microwaveassisted transesterification (One-step) was carried out. A two-step transesterification process was used to produce biodiesel (alkyl ester) from high free fatty acid (FFA) waste cooking oil. Microwave-assisted catalytic transesterification using BaO and KOH was evaluated for the effica...

The increasing vehicular population causing consumption of petroleum fuels at a faster rate and causes increase in the danger of petroleum fuels depletion and the remarkable increase in high crude oil prices. The increasing consumption of petroleum products has been a matter of great concern for the country for the financial growth as well as environmental pollution abatement. The situation off...

The present work aims to investigate the effects of the addition of waste cooking oil (WCO) on heavy crude oil biodegradation and microbial enhanced oil recovery (MEOR) using Pseudomonas sp. SWP-4. Growth kinetics show Pseudomonas sp. SWP-4 had a maximum dry cell weight of 1.73 g/L and cell-surface hydrophobicity of 62.4% against n-hexadecane when degraded the crude oil with the addition of WCO...

The price of feedstock is one of the most significant factors affecting the economic viability of biodiesel manufacturer. Many approaches were investigated to reduce the biodiesel production cost. The present work gave a preliminary study of two approaches to economically produce biodiesel from waste cooking oil (WCO) and flaked cottonseed. One was the use of ultrasound-assisted synthesis of bi...

This study is based on optimizing the experimental conditions of biodiesel production by base-catalyzed transesterification using waste cooking oil (WCO). In this study, the key parameters varied were methanol (20, 25, 30, 35, and 40%), sodium hydroxide (0.4, 0.6, 0.8, 0.9 and 1.0g), reaction time (40, 60, 90, 100 and 120 minutes) and reaction temperature (50, 52, 55, 58, and 60 C). Maximum bio...

The influence of waste cooking oil (WCO) on the performance characteristics of asphaltic materials indigenous to Trinidad, namely, Trinidad Lake Asphalt (TLA), Trinidad Petroleum Bitumen (TPB), and TLA : TPB (50 : 50) blend, was investigated to deduce the applicability of the WCO as a performance enhancer for the base asphalt. The rheological properties of complex modulus (G (∗) ) and phase ang...

The ageing of the bitumen during storage, mixing, transport and laying on the road, as well as in service life, are the most important problems presented by the use of bitumen in pavements. This paper investigates the possibility of using waste cooking oil (WCO), which is a waste material that pollutes landfills and rivers, as an alternative natural rejuvenating agent for aged bitumen to a cond...

In recent years, Reclaimed Asphalt Pavement (RAP) has become very popular in pavement construction due to its benefits the economy and environment. The present study investigates feasibility of employing Waste Cooking Oil (WCO) Engine (WEO) as rejuvenators blended with reusable asphalt binder through physical rheological properties at high intermediate temperatures. Examined conventional WCO-an...
