Btsl phases

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

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

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 management1

3.2 Leachate Management


  • 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 management2

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 management3

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

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 management1

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

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


4 discussion1


  • 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


4 discussion2


  • 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
