Major Waste Streams or Area of Losses

  • 1. Dust, husk, traces, mudball and stones due to
    • removal from received seed
    • 2. Leakage of Hexane vapours due to
    • drying of DOC
    • dissolving in steam and water
    • leakage in different compartment
    • incomplete retrieval from mineral oil
    • evaporation losses and vent losses
slide7

3. Mineral oil wastages due to

    • inadequate recycling process
    • 4. Crude oil losses due to
    • Retention in DOC
    • Leakages during transportation and storage
    • Insufficient cooking and flaking
slide8

5. Energy losses due to

    • Inefficiency in conversion and transportation of steam
    • Poor quality of coal
    • Obsolete technologies
    • Poor maintenance

GP Policy For The Plant

  • We at Rama Phosphates Ltd will strive as an organization to reduce the level of hexane wastage as it will lead to better productivity and work towards our aim of sustainable development by conserving natural resources.
  • In order to achieve this, we aim to practice:
  • To meet relevant environmental legislation
  • To prevent pollution, reduce waste and resource consumption, encourage recovery & recycling as opposed to disposal, where feasible
  • To introduce state of the technology to enhance plant efficiency and reduce losses
  • To ensure proper health & safety working environment for all employees
