Accessible from North-South Expressway (PLUS) via Bukit Tagar Interchange (Exit 113B)

4. Location Map

5. BTSL Plan

6. BTSL Phases

7. 3. DESIGN AND FACILITIES
Fully engineered Level IV landfill with complete High Density Polyethylene (HDPE) membrane liner
Leachate collection and treatment systems
Comprehensive ground and surface water monitoring systems
17 phases over 40 years
120 million metric tones of air space capacity
Serves municipal and non-toxic (scheduled) solid waste for Central region of Selangor and Kuala Lumpur
Primarily routed from Kuala Lumpur Solid Waste Transfer Station in Kepong

8. BTSL Schematic Design

9. 3.1 Landfill Operation
Manpower: 45. Headed by Operations General Manager. Three shifts, seven days a week (24-hours)
24-hours security patrols and checkpoint for screening of incoming wastes
Smartcard systems for vehicle identification and data logging
Full range of trucks and compactors

10. 3.2 Leachate Management Leachate Treatment Plant Features
Treatment capacity – 1,000 cubic meters per day
Four leachate holding ponds – 180,000 cubic meters leachate storage capacity
SCADA systems; computerized and automated controls of pumps and valves
Primarily biological reaction with series of chemical dosing
Equipped with four Sequential Batch Reactor (SBR) lagoons

11. 3.2 Leachate Management …continued
Red beds – consists of phragmites plant capable of absorbing residues in treated leachate
24 aerators
Chemicals storage and dosing systems
Balancing tanks
Sludge thickener
Dissolved air floatation plant

12. 3.2 Leachate Management Treated Effluent Management
Zero discharge policy
Treated effluent is irrigated into 120 acres field; allowing the effluent to undergo evapotranspiration and soil moisture retention processes
Leachate Quality Test
Conducted on daily, weekly and fortnightly basis at SBR lagoons
pH, nitrites, nitrates, ammoniacal nitrogen, dissolved oxygen (DO), BOD, COD

13. 3.2 Leachate Management Gas Monitoring
Waste gas is channeled via pipes and vented to outside environment
No specific gas collection system is currently employed
Future plan includes biogas collection system with biogasification plant to produce electrical energy for BTSL energy requirement

14. 3.3 Environmental Management
Surface Water Management System
Storm water runoff is diverted away from landfill via surface drains towards open water courses, silt traps and detention ponds
Daily earth cover to prevent ilfiltration of rain water
Regular desilting of silt traps

15. 3.3 Environmental Management
Environmental Monitoring
Surface and ground water monitoring on monthly basis
pH, nitrites, nitrates, ammonia, e-coli, suspended solids and trace metals
Ambient air quality and noise levels on quarterly basis
Quarterly Environment Monitoring Reports to be submitted to the DOE
Early Warning and Emergency Containment System (see chapter 3.4)

16. 3.4 Emergency Preparedness
Emergency response system
Leachate containment bund to prevent accidental leachate breakout
Continuous flow meter
Detention dam
Holding ponds
On-going training comprehensive training program to ensure optimum standards
Regular briefing
Trial runs on safety and emergency procedures

17. 4. DISCUSSION Location of landfill is suitable
Proper, direct and easy access via PLUS expressway
Not far away from Klang Valley
Minute area with sparse human population
Continue…

18. 4. DISCUSSION Superb design and facilities
Fully engineered Level IV landfill
World class technology with computerized, automated and integrated leachate management
Protection to the environment quite well done, but no ISO14001
Gas monitoring and collection
No collection of waste gas is being employed
Continue…

19. 4. DISCUSSION Environmental monitoring Environmental protection
Good efforts, but monitoring schedule only for quarterly basis
Environmental protection
Good efforts
Health and Safety
Can be improved; holistic medical surveillance of staff
PPE; should be supervised and updated from time to time

20. 5. CONCLUSION
BTSL is a newly operated Level IV landfill with advanced leachate treatment facilities
Currently, only Phase 1 is operational
Accepts municipal, non-hazardous solid waste from Central Region of Selangor and Kuala Lumpur
Future plan include utilization of biogas
Future land use for recreational purpose
