The activated earth and carbon are removed by using a commercial filter. The spent earth-carbon, thus obtained, retains around 20%–25% oil content. Bleaching castor oil containing higher phosphatide and soap content often leads to high retention of oil due to the large amount of activated earth used and thus causes filtration issues.

Waste activated bleaching earth (ABE) that contained 40% rapeseed oil and was discharged by an oil refinery plant, was used for riboflavin production in a culture of Ashbya gossypii.When 125 g/L waste ABE that contained 50 g/L rapeseed oil was added into the culture, the riboflavin concentration was 1.12 g/L, which was almost 1.6-fold as high as that of pure rapeseed oil.

An estimate 120 Million MT of oil are processed with bleaching earth globally and 2.5 Million MT of spent bleaching earth is released. Assuming an average oil retention value of 30% for the bleaching earths normally used, approximately 75,000 MT of oil is lost in the bleaching process constituting a significant economic loss.
