Biodegradation and Dewatering of an Industrial Waste Oil
Waste oil generated from industrial operations at a diesel locomotive maintenance facility was investigated to establish its treatability and potential volume reduction. The waste oil and water mixture separated into four distinct layers; free oil, emulsified oil, weathered oil, and wastewater. The …

DEVELOPMENT OF MICROWAVE SPECTROSCOPIC RESONANT SENSOR FOR APPLICATION IN EDIBLE AND WASTE OIL VERIFICATION
… is a contribution and value addition to edible oil verification and the waste oil recovery process. It comprised the development of a sensing technique that will primarily enable the ability to probe different oils and establish their differences for authentication, and in addition test free …

Sustainable treatment of oil contaminated waste: oil-based mud (OBM) drill cuttings and soil.
Environmental pollution from oilfield drilling waste poses potential hazards which can lead to ecological imbalance. The predominant pollutant from oilfield waste is petroleum hydrocarbons. Some effects of petroleum hydrocarbon contamination in soil include loss of nutrients, reduced fertility, …

A new method for the routine trace analysis of polychlorinated biphenyls in waste oil and contaminated soil
… with levels higher than 50 mg/l. PCB analysis in oils and oil contaminated soil is normally expensive in terms of time, instrumentation and uses large volumes of hazardous solvents which further increase cost per sample. Commercial laboratories are constantly under pressure to provide a faster …

Study of Hydrocarbon Waste Biodegradation and the Role of Biosurfactants in the Process
Two types of oily waste sludges generated by a railroad maintenance facility were studied to reduce the volume of hydrocarbon waste. The specific goals of this laboratory study were to evaluate rate and extent of microbial degradation, benefits of organism addition, role of biosurfactant, and …

Photodegradation of biopolymer doped with titanium dioxide (TiO2) as ultraviolet (UV) stabilizer
A large amount of waste cooking oil has become an environmental issue around the world. This oil is renewable and biodegradable than the corresponding products made from petroleum sources. The major concern in this study focuses on the resistance of the biopolymer to ultraviolet (UV) light …

Removal of Organic Micro-Pollutants from Water Using Sewage Sludge Based Composite Adsorbents
<p>Millions of tons of sewage sludge, waste oil sludge and fish waste are produced annually, and improper treatment/disposal of these wastes have resulted in numerous environmental issues. On the other hand, these wastes are rich in organic materials, metals, and inorganic minerals and could be …

Harvest-Time Optimal Path Planning in Dynamic Flows
… vehicles, tasked with harvesting plastic waste, oil spills, or seaweed fields, need to be able to plan paths that maximize the amount of material harvested in order to optimize the cleanup or collection process. In this work, we develop an exact partial differential equation-based …

Creating Standards Compliant Biodiesel Production Capability Using Waste Peanut Oil at Embry-Riddle Aeronautical University
… the process of making a viable biodiesel using waste peanut oil from a Chick-Fil-A fast food restaurant on campus. Past research and biodiesel production from the previous two years on campus was taken into consideration and a catalyst change was proposed. Sample test batches were conducted to …

Field Trials of Ex Situ Smouldering Treatment (STARx) of Oil Sludge
… for remediating these sites and their produced wastes. Self-sustained liquid smouldering – known as STAR technology - has been studied extensively at small scales and has been proven as an effective in situ remediation technique for heavy hydrocarbons. However, STAR as a large-scale ex situ …
