Spent bleaching earth (SBE) is a waste generated by the edible oil industry that currently has limited options for beneficial reuse. In excess of ∼2 million tonnes per year of SBE is generated world-wide with major quantities available in the middle-east where significant volumes of edible oils are produced. Low pressure compaction followed by heat treatment at 150°C causes polymerisation of th...

High free fatty acids in waste cooking oil can interfere with the re-use of oil. Therefore, absorption technique is one way that reduce contained Aim: The purpose this study to find out ability Reactivated Spent Bleaching Earth (RSBE) adsorb be biodiesel products. In study, was collected from fried food sellers Bekasi, while spent bleaching earth (SBE)-one solid wastes produced by refinery palm...

In this study, compressive strength, density, porosity, and methylene blue adsorptive intensity of sodium aluminosilicate monolith produced from coal fly ash (CFA), ceramic tile waste (CTW), spent bleaching earth (SBE) were evaluated. Using simple lattice mixture design, CFA-CTW-SBE blend with mass ratio 55.95% CFA, 38.73% CTW, 5.31% SBE, an alkali solution containing 80% 8M NaOH 20% silicate, ...

In the era of industry and technology in Indonesia, environmental problems due to waste are that require wise handling. Fly Ash (FA) from PLTU activities Spent Bleaching Earth (SBE) resulting palm oil production process very abundant, thus polluting environment. Indonesia is currently prioritizing physical infrastructure development, which aims improve connectivity encourage economic growth eve...

The objective of the study was to effects spent bleaching earth (SBE) and deoiled (DBE) filler-based NPK fertilizers on agronomical characteristics soybean as a model crop. A field experiment arranged in single factor randomized complete block design (RCBD) with four blocks replications. treatments were 1) fertilizer 10% BC (control), 2) 5% + SBE, 3) DBE. variables observed levels heavy metals ...

Bentonite bleaching earth is utilized for purifying used motor oil through a recovery process in order to improve the quality and stability of the final product. Indeed, spent bleaching earth is generated due to adsorbing oil impurities. Polluted spent bleaching earth contains 20-40% (w/w) oil and is flammable. Its disposal without pre-treatment leads to loss of oil along with environmental imp...
