• What is Bleaching Earth?

    Bleaching Earth is a solid waste material generated as a part of the refining process in the edible oil industry, worldwide. 

  • What is the current application of Bleaching Earth?

    Bleaching Earth is usually disposed of in landfills or waste dumps. Due to increasing cost of disposal and being an environmental hazard, it is desirable to recover oil using a Solvent Extraction process in an efficient and economical manner, before disposing off Bleaching Earth as per environmental regulations.

  • How much oil does Bleach Earth absorb?

    In refining, bleaching earth is used to remove color, metal, phosphatides, oxidized products and residual gums from the oil; however, in turn, it absorbs approximately 20-40 % by weight of the Bleaching Earth.

  • How much oil can be recovered during the Solvent Extraction process?

    The Oil in Bleaching Earth can be recovered using our patented technology leaving less than 1% in the Bleaching Earth which meets the environmental regulations for the disposal of  bleaching earth for any application

  • What are the areas of application of oil recovered from this process?

    The oil recovered immediately after the bleaching process by extraction with a solvent can be used as feedstock to a refinery. Otherwise it can be reused as a raw material for industrial applications to save costs in the processing industry. As the residual oil has a very high FFA and Peroxide Value, it can only be used for non-food applications, as feed stock for conversion to Biodiesel, and as a lubricant base for bio-lubricants as a feedstock to the oleo-chemical industry.

  • What are the process highlights?

    In our process, the oil can be recovered from Bleaching Earth using both a flammable as well as non-flammable solvent, which has been done for the first time in the world.

  • What are the applications for de-oiled Bleaching Earth?

    The output de-oiled Bleaching Earth is safe for disposal in land fill. It can also be used as a fuel in the boilers. The anhydrous clay can be used in Cement manufacturing. It can also be used in manufacturing Fertilizers containing silica/silicates or can be used as a soil amendment, as it poses no harm to the soil and acts as a soil conditioner

  • Is it safe to dispose of Bleaching Earth without treating?

    Due to the high oil content in the Bleaching Earth, its disposal can cause environmental hazards, since it is prone to catching fire, besides polluting the ground water. With the regulatory restrictions in place in most countries, the need to lessen the environmental impact is of growing importance and concern to the industry

  • What is the project implementation time?

    Usually the project implementation schedule varies from 8 months to 12 months depending upon the location and soil condition.
