Spent bleaching earth; recycling and utilization techniques
Spent bleaching earth (SBE) is a waste created by the vegetable oil refining industries that right now have restricted alternatives for advantageous reuse. An overabundance of about 2 million tons for each time of SBE is created worldwide with significant amounts accessible in the Middle East countries where noteworthy volumes of edible oils

The spent bleaching earth (SBE) from the edible oil refining industry was successfully regenerated through an extraction process using different organic solvents for removal of residual oil
Abstract. A spent bleaching earth (SBE) from an edible oil refinery has been regenerated by thermal processing in oven, followed by washing with a cold solution of hydro-chloric acid (1M). Optimal regeneration conditions have been controlled by decolorization tests of degummed and neutralized soybean oil.
The reuse of spent bleaching earth: A feasibility study in
The bleaching stage in an edible oil refining process produces large amounts of spent bleaching earth (SBE) which contains high quantities of low-quality residual oil (20–50% w/w). SBE is usually disposed of in landfill, which is expensive, not environmentally friendly, and represents an inefficient use of a potentially useful and valuable by
naturally undesirable for edible oil producers. “Bentonites result in about 15-20% oil loss, whereas attapulgites and sepiolites cause about 30-35% oil loss. That oil loss is a very important contributor to the total cost of vegetable oil refining,” says Howes. Attapulgite and sepiolite can also pose a potential health hazard to oil refinery

The spent bleaching earth (SBE) from the edible oil refining industry was successfully regenerated through an extraction process using different organic solvents for removal of residual oil, followed by through heat treatment. The total percentage of extracted oil (PEO) for the solvents used s...
Types of Edible Oils Refining There are two oils refining types like chemical refining and physical refining (also called neutralizing distillation). Chemical refining removes free fatty acids by a neutralization step with sodium hydroxide; the neutralizing distillation removes these undesirable compounds (de-acidification) by distillation
[PDF] Recovery of Vegetable Oil from Spent Bleaching Earth
Vegetable oils undergo numerous refining steps in order to remove undesirable compounds and produce high quality, stable commercial products. Recovery of vegetable oil from spent bleaching earth is an area where ample opportunities exist for cleaner production and cost saving in the vegetable oil processing industry. Conventional oil extraction and refining processes, which involve multiple
regenerated spent bleaching earth, against 77.4 and 92.7% for the same oil processed by a commercial virgin bleaching earth. The results obtained after decolorization of an edible oil with a
