CHAPTER 10
SUSTAINABLE WASTE MANAGEMENT
DEFINITION
To reduce the amount of natural resources consume in order to maintain the balance between environment, social and economics
In Malaysia
Waste generated in 2016 was 38200 tons/day with recycling rate 17.5%.
Expected in 2020, the waste generated was 45900 tons/day and government plans to reduce the waste disposed in landfill
Current Practices for Malaysia Municipal Solid Waste Management

Method of Waste Disposal in Malaysia
Technologies
Landfill-ultimate waste disposal method
161 landfill still operation, 141 are closed
Incinerators
In modern refuse-derived fuel plants, incineration occurs at extremely high temperatures around 900-1200 °C (1800-2100 °F) for long enough to minimize the release of pollutants.
Facility for construction and demolition
Anaerobic digester (food waste facility)
Composting plants
Recycling electrics and electronics device
Disposed in open landfill every year
Amount of e-waste grows 14% every year in Malaysia
Challenges
Lack of well recycling market
Insufficient funds
Insufficient technologies and facilities
Insufficient regulations
lack of awareness
Current Practices for Malaysia Construction Waste Management
Policy
Construction Industry Development Board (CIDB)- Transform industry by improving environmental performance
Established
Standard Specifications for Building works (SBW) - to ensure the garbage and construction clearance is done twice a week and will send to landfill whilst Pembinaan Malaysia Act 1994 is to prevent and reduce pollution that caused by construction
Technologies
Waste minimization
Waste reuse and recycling
Composting
Area that should sustainable waste management
Waste Segregation Facility (WSF)
Fully Anaerobic Bioreactor System (FABIOS) Plant
Waste Receiving Facility (WRF)
Power Generation Facility which includes Biogas Power Plant and Waste-to-Energy Plant
Collection and Disposal
Sanitary Landfill for commingled, inert solid waste and processed waste residuals
Leachate Treatment Facility
Salvaging Yard for combustible solid waste and recyclables
Operations & Maintenance of Waste
Facility Infrastructural
Ancillary Works
Methods
Waste prevention
Reduce waste generation
Practices grass cycling
Backyard composting

Recycling creates new products, Reuse, Reduce and Recovery
Advantages
Conserve resources
Reduce need for new landfill and combustor
Save energy
Reduce pollution
Prevent emission of greenhouse gases
