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.

4. 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

14. 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.

18. MONITORING CATEGORIES
 Liquid Volume
 Liquid Head on Liner
 Leachate characteristics
 Landfill Gas Quality
 Landfill Gas Volumes
 Gas Emissions
 Waste Characteristics
 Landfill Settlement
 In-situ Instrumentation

20. 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

21. CHALLENGES
• Leachate Seepage
• Temperature Control
• Gas and Odor Control
• Fire and Explosions

22. LEACHATE SEEPS

23. 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.
