Design & construction of secure waste landfill

  1. 1. Design & Construction of Secured Landfill for Municipal & Industrial Solid Waste 1
  2. 2. Types of Solid Waste  Municipal Solid Waste (MSW)  Industrial Hazardous Waste  Bio Medical Waste(from Hospital)  E- Waste (Electronic Waste) 2
  3. 3. Consists of :  Household waste (From Kitchen & household Rubbish)  Construction and demolition debris  Commercial waste (from shops- offices) Municipal Solid Waste (MSW) 3
  4. 4. Consists of waste from:  Petrochemical industries  Metallurgical industries  Pharmaceutical industries  Fertilizer industries  Other hazardous process industries Industrial Hazardous Waste 4
  5. 5. Waste Type Laws in India Action by Enforcement Authority Municipal Solid Waste Municipal Waste Management & Handling Rules -2000 City Municipality State Pollution Control Board Industrial Waste Hazardous Waste Management & Handling Rules- 1989 Industry State Pollution Control Board E-Waste E-waste Rules-2011 All Electronic users & manufacturers State Pollution Control Board Bio Medical Waste Bio-Medical Waste Rules -1998 Hospitals State Pollution Control Board Applicable laws for Waste Disposal 5
  6. 6. To ensure that: • Waste is disposed in scientific manner • So that waste disposal does not damage air, water, soil, human health due its chemical, acidic, radioactive characteristics. Scope of Waste Laws & Rules 6
  7. 7. Disposal Methods of Waste Landfill Incineration Recycle 7
  8. 8. Disposal of Waste to Landfill  Landfills are ultimate means of disposal of waste  These inert waste like construction debris etc have large volume approximately 60 to 70 % of MSW  Large area is required for secured landfill.  The cost of landfill construction is Rs 500 to Rs 1500 per ton of waste. 8
  9. 9. Time of Decomposition of waste Type of Waste Time to Decompose Organic wastes : vegetable & fruit peels, leftover food stuff etc. 2 - 7 days Paper 10-30 days Cotton Cloth 2 - 5 months Carpets 1 year Tin, Aluminum cans etc. 100-500 years Plastic Bags, one million years Glass Bottles Undetermined 9
  10. 10. Microorganism decomposes waste mass into leachate and methane gas First stage: aerobic organism converts waste into simple organic compounds, CO2 & H2O. Second Stage: anerobic organism converts organic compounds into H2,NH3,H2O, CO2 & organic acids. Third Stage: methane forming organism converts organic acid into CH4. Process of decomposition of Waste 10
  11. 11. Leachate (Toxic Liquid) is generated due to decomposition of waste in the landfill. Leachate contains acid, heavy metals, other toxic elements. Leachate contaminates ground water resources. Leachate is collected in wells inside landfill & pumped out for treatment. Leachate in landfill 11
  12. 12. Methane gas is generated in waste mass Gas is collected in pipe & taken out from landfill Gas is sent to power plant (high calorific value) Gas travels underground in cracks of rocks if not pumped out.  Gas accumulated in nearby area (foundation of buildings and causes explosion. Landfill Gas (Methane) 12
  13. 13. Design & Construction of Landfill (1) Characterization of waste (2) Design of Impervious Liner (3) Reclamation of Leachate (4) Construction of landfill (5) Operation of landfill (6) Environmental Monitoring 13
  14. 14. GUIDELINES FOR LANDFILL DESIGN (1) Central Pollution Control Board-India -1998  Guidelines for setting up of operative facility : Hazardous Waste Management (http://cpcb.nic.in/upload/NewItems/NewItem_133_M SW-REPORT.pdf) (2) USA Environment Protection Agency  The Guide for Industrial Waste Management (https://www.epa.ie/pubs/advice/waste/waste/EPA_l andfill_site_design_guide.pdf) 14
  15. 15. Major elements of Landfill The secured land fill consists • HDPE liner, • leachate collection well & pipe network, • earth moving machineries, • site office, • workshop • Green belt etc. 15
