Background and purpose: Due to the lack of accurate statistics on the amount of waste generated in the energy production sector in Zahedan, before any planning, one should identify all waste producing centers associated with the energy sector and also the quantity and quality of their waste in Zahedan. Materials and methods: This research is a cross-sectional descriptive study. It examined the ...
This study reviews the problems in the use and disposal of poly (ethylene terephthalate) (PET) and includes the concise background of virgin and recycled PET as well as their possible applications. The current state of knowledge with respect to PET recycling method is presented. Recycling of PET is the most desirable method for waste management, providing an opportunity for reductions in oil us...
The superior oil absorption capacity of recycled polypropylene (PP) fiber and waste tire powder were used to recover spilled engine oil. We used ASTM F726-99 method to evaluate oil adsorbing capability of PP fiber and found it to have a large, rapid oil sorption capacity. However, its lack of elasticity dramatically limited that capacity after repeated use. Tire powder, which absorbs less oil m...
Contamination of soil with toxic substances can degrade its capacity to grow plants. A Randomized Complete Block Design (RCBD) experiment was set up in 2005 and 2006 to evaluate the effect of organic wastes on the physical properties and maize (Zea mays L) yield of spent oil contaminated (SOC) ultisol in Abakaliki South eastern Nigeria. The wastes comprising poultry droppings (PD) and Rice husk...
Global environmental pollution challenges can be alleviated if proper disposal and conversion of wastes is promoted. An attempt of converting waste to wealth was made in this study by converting oil palm empty fruits bunch to activated carbon through chemical activation with potassium hydroxide which was used for adsorption of Rhodamine B dye from waste water. Fixed-bed column adsorption system...
This paper presents an economic study of a novel thermal fry-drying technology which transforms sewage sludge and recycled cooking oil (RCO) into a solid fuel. The process is shown to have significant potential advantage in terms of capital costs (by factors of several times) and comparable operating costs. Three potential variants of the process have been simulated and costed in terms of both ...
Pharmaceutical industry represents a range of industries with operation and processes as diverse as its product. Hence effluents coming from pharma industries vary from industry to industry. Thus it is almost impossible to describe a typical pharmaceutical effluent because of such diversity. Waste water is generally evaluated in terms of temp, pH, Total suspended solid (TSS), BOD, COD, Oil & gr...
With ever increasing concern on oil prices and energy conservation, there is a fast growing interest in hybrid vehicles globally. Currently, all hybrid vehicles, including micro, mild and full hybrids, adopt internal combustion engines which are inefficient in general. The corresponding waste heat of exhaust gas constitutes up to 40% of the fuel consumption. So, it is a pressing need for resear...
Worldwide energy crisis forced the researchers to explore for new and alternate sources of energy. For the developing countries this problems are acute. Generation of any kind of waste is a problem to the environment. Some wastes have the characteristics of producing energy by different thermochemical conversion. In the present work, waste tires were pyrolysed in a fixed bed reactor. The influe...
