Increase in energy demand, stringent emission norms and depletion of oil resources have led the researchers to find alternative fuels for internal combustion engines. On the other hand, waste oils pose a very serious environment challenge because of their disposal problems all over the world. In this context, waste oils are currently receiving renewed interest. The properties of the oil derived...
Abstract Background & Aim: Increasing the population growth and the number of health care facilities Lead to use of disposable medical equipment, so it caused increasing the medical waste production. Improper disposal of medical waste poses a serious threat to the environment and public health. Thus the aim of the present study was to determine awareness of the nurses about medical waste man...
WASTE OIL RECOVERY. Prior to 1960, a significant portion of the demand for automotive lubricating oil was met by re-relined used oil. At the time, 150 re-refineries produced 300 million gal of motor oil annually. Since 1960, however, the production of re-refined oil has steadily declined. In 1981, for example, out of about 1.2 billion gal of automobile lubricating oil and 1.6 billion gal of ind...
In this study, waste edible oil was prepared by both heat and aeration treatment, and the increasing inhibitive effect of tocopherol treatment on the acid value (AV) and carbonyl value (CV) of the oil was investigated. The AV and CV of waste edible oil treated with tocopherol were 0.1-1.0% lower than those of the nontreated oil, indicating that tocopherol exerted a radical-scavenging activity. ...

Two bacterial strains phylogenetically identified as Pseudomonas aeruginosa strains RM1 and SK1 displayed extensive degradation ability on waste engine oil (SAE 40W) in batch cultures. Spectrophotometric analysis revealed the presence of various heavy metals such as lead, chromium and nickel in the waste engine oil. The rate of degradation of waste engine oil by the isolates, for the first 12 d...
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...
in this study,oil was extracted from the liver and visceral fat of patin (pangasianodon hypophthalmus) and refined. the yield of oil after refining was 49.98%. the major yield loss (34.20%) happened during the degumming procedure. fatty acids found in the crude and refined oil were c12:0, c14:0, c14:1, c16:0, c16:1, c18:0, c18:1, c18:2, c18:3, c18:4, c20:0, c20:1, c20:4, c20:5, and c22:6. the d...
