Bioreactor landfills

  1. 1. BIOREACTOR LANDFILLS MADE BY: ANKITA PAYAL SONALI FARTIYAL
  2. 2. BIOREACTOR LANDFILL -AN INTRODUCTION  An innovative technology for biostabilization of municipal solid waste.  A controlled landfill where liquid and gas conditions are actively managed in order to accelerate or enhance biostabilization of the waste.  Control, monitor and optimize the waste stabilization process rather than simply contain the wastes.  It requires certain primary technologies to enhance and control the waste stabilization process like liquid or air addition, temperature, pH and nutrient level.
  3. 3. CONVENTIONAL VS. BIOREACTOR LANDFILL  Basic principle of conventional landfill is to contain and store the waste  Called as “Dry Tomb” landfill  Takes about 30-50 years for decomposition  Leachate generation and release of landfill gases can pose long term environmental risk  Basic principle of a bioreactor landfill is the treatment of waste by decomposition  Decomposition occurs in a shorter period of about 5- 10 years  Tackles some of the major environmental problems

  7. 7. TECHNIQUES OF LIQUID ADDITION Recirculation of leachate Surface Systems • Spray irrigation • Drip irrigation • Tanker truck application • Infiltration ponds • Leach field • Surface trench Subsurface System • Vertical injection wells • Horizontal trenches • Buried infiltration galleries • Combination of horizontal lines and vertical wells

  11. 11. VERTICAL WELLS
  12. 12. LANDFILL GASES Direct by-product of anaerobic waste decomposition Gas from anaerobic decomposition of waste is primarily composed of methane (CH4) and carbon dioxide.  Other trace components such as water vapor, hydrogen sulfide and a variety of organic chemicals, are also founds in LFG.

  15. 15. WHY BIOREACTOR LANDFILLS?  WASTE STABILIZATION  LEACHATE TREATMENT, CAPITALAND OPERATING COST  POTENTIAL FOR AIR SPACE RECOVERY  LANDFILL GAS GENERATION RATES  ENVIRONMENTAL IMPACTS  POST CLOSURE CARE, MAINTENANCE AND RISKS
  16. 16. CHALLENGES • Leachate Seepage • Temperature Control • Gas and Odor Control • Fire and Explosions
  17. 17. LEACHATE SEEPS
  18. 18. NON-TECHNICAL BARRIERS TO THE BIOREACTOR LANDFILLS • Limited regulatory awareness and negative perception. • Dearth of site-specific performance quantification. • Limited availability of project economic assessments. • Insufficient project sustainability experience. • Lack of financing experience. • Extended time expectations for planning permitting and licensing. • Increased regulatory constraints and conditions.
