Abstract In comparison to fats, oils and grease (FOG) found in commercial industrial effluents, very little is known about FOG discharged at household level. To address this shortcoming, production was calculated following a year‐long monthly collection 2.3 kg/year per household, equivalent 0.8 capita. the United Kingdom, these numbers translate an annual estimated of 62 380 tonnes. Physico‐che...

The possibility of obtaining eco-safety surfactants and high-temperature dispersed phase thixotropic plastic systems based on waste food oils were demonstrated. structure the synthesized fatty acid alkanolamides was confirmed by IR 1H NMR spectroscopy. upper temperature limit (above 463 К) for use acids complex calcium grease determined thermogravimetric analysis. introduction to composition im...

The most commonly used method for biodiesel preparation is via transesterification of vegetable oil using alkaline catalysts. Biodiesel yield and oil conversion are affected by operating conditions including the catalyst formulation and concentration. Application of alkaline catalysts can also lead to undesired soap formation. This study evaluated the alkaline catalyst effects on biodiesel yiel...

This study concentrates on developing and tuning various oil analysis methods to meet the requirements of modern industry and environmental analytics. Oil analysis methods form a vital part of techniques used to monitor the condition of machines and may help to improve the overall equipment effectiveness value of a factory in a significant manner. Worm gears are used in various production machi...

Cooking oil waste leads to well-known environmental impacts and its bioremediation by lipase-based enzymatic activity can minimize the high cytotoxic potential. In addition, they are among the biocatalysts most commercialized worldwide due to the versatility of reactions and substrates. However, although lipases are able to process cooking oil wastes, the products generated from this process do...

Biodiesel has attracted increasing interest and has proved to be a good substitute for fossil-based fuels due to its environmental advantages and availability from renewable resources such as refined and waste vegetable oils. Several studies have shown that biodiesel is a better fuel than the fossil-derived diesel in terms of engine performance, emissions reduction, lubricity and environmental ...

Glycerol is the principal by-product of biodiesel production. For each gallon of biodiesel produced, approximately 0.3 kg of crude glycerol accompanies. Such crude glycerol possesses very low value because of the impurities contained. As the demand and production of biodiesel grow exponentially, the utilization of the glycerol becomes an urgent topic. The make-up of crude glycerol varies depend...
