1. INTRODUCTION
The Stake Holders
KUB-Berjaya Enviro Sdn. Bhd. (KBE)


Joint-venture company between KUB Malaysia Berhad
and Berjaya Corporation Berhad.
Public listed company (Plc.), listed on Kuala Lumpur
Stock Exchange (KLSE)
Supervision
Government of Malaysia

Ministry of Housing and Local Government
2. LOCATION
 Hulu Selangor district
 Approximately 50Km north of Kuala Lumpur
 Developed on 700 acres land area
 1,000 acres of buffer zone
 Surrounded by palm plantation
 Accessible from North-South Expressway
(PLUS) via Bukit Tagar Interchange (Exit
113B)

BTSL Plan
BTSL Phases
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
BTSL Schematic Design
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
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

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
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
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
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
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)
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
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…
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…
4. DISCUSSION
 Environmental monitoring
 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
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
