CHAPTER 9: Hazardous Waste Management :explode: :warning:
Introduction
Definition
Malaysia
Any waste falling categories waste listed in 1st Schedule of Environment Quality (Scheduled Wastes) Regulation 2005
International
Solid, liquid, contained gaseous matter no longer use
EQ(SW)2005
First Schedule
SW 1 Metal and metal bearing waste
SW101 Waste containing arsenic or its compoun
SW108 Leaching residue
SW102 lead acid batteries
SW103 Waste batteries contain cadmium, nickel, mercury or lithium
SW110 Electrical and electronic assemblies
SW 2 Inorganic constituents may contain metal
SW202 Waste catalyst
SW203 Immobilized scheduled waste
SW201 Asbestos waste in sludge

SW412 Sludge containing cyanide
SW417 Waste of inks, paints, pigments, lacquer, dye or varnish
SW407 Waste containing dioxins or furans
SW5 Other waste
Import/Export HW
Malaysia not allow HW including e-waste into the country
Allow importation used electronic equipment for direct reuse
Guidelines for the Classification of Used Electrical and Electronic Equipment in Malaysia, DOE 2008
Malaysia Hazardous Waste Management Strategy
Objective
human health protection
environmental cleanliness
Caurses
No regulation till 1989, thus no comprehensive hazardous waste management acilities
Industrial waste disposal freely
No proper treatment lead to poor air quality
Contamination of ground water
chemical and biological agents causing adverse effect on human and environment
After Sixth Malaysian Plan 1991-1995
Industrial began to treat, recycle, reuse waste material
stepped up programs to render all schedule waste
National Policy on the Environment
harmonizing economical development goals in line with environmental imperative
enforcement of regulation with tax rebates to promote compliance
Penalty for non-compliance
Scheduled Waste Management Facilities
Current facilities used in Malaysia
Clinical waste incineration
Off-site physio-chemical waste treatment facilities
Scheduled waste incineration plant which can be on-site or off-site
Centralized waste treatment facility
Secure landfill—for final disposal of stabilized wastes
Resource recovery
Off-site waste storage and waste transfer stations/facilities
Land treatment
Scheduled/hazardous waste transport facilities
Waste water/sewage treatment facilities
Process to estalish facilities
operator apply license through Environment Department Director General Offiece
Environmental impact assessment (EIA)
proposes site inspection
access suitability for the operation against environmental pollution
written permission
all qualifying document for the operator
prove capability to run the operation
conformity with the EQA, 1974 and other environmental regulations
Pre-licensing inspection
Processing of the operating license
Classification facilities
Including
waste storage facility
waste recovery facility
recycling facility
incinerator
contiguous land
secure landfill
Facility can fuction independently
type of hazardous waste that it handles
a combination of technologies
in the case of commercial facility
processing different types of wastes
Company
Kualiti Alam Sdn. Bhd
Begining
growing problem of hazardous waste generation
strategies to carterhazardous waste
surveys on hazardous waste generation and the effect on the environment were conducted by (DOE) in 1985
first legislation on hazardous waste in 1989
supported with national scheduled waste program
developing an integrated scheduled waste management system
Kualiti Alam Sdn. Bhd, a consortium of Malaysian
Responsibility
waste collection
transportation
treatment
final disposal of hazardous waste
Integrated scheduled waste management system
Stabilization/solidification and physical and chemical treatment facilities
stabilizes neutral inorganic waste
reduces hazardous substances mobility
Physical and chemical methods are often used
combination with solidification
to separate or transform hazardous substances to less harmful materials
Inorganic wastes
reduced to neutral pH values
stabilization employed
Incineration
treats 120,000 metric tons wastes per year
wastes contain organic carbon level above 10% are disposed only by incineration
Kualiti Alam Sdn Bhd incineration
a rotary kiln
secondary combustion chamber
flue gas-cleaning system
Operation
High temperature
volatilely destroys the hazardous waste
produce ash
disposed to secured landfills

Secured landfills
final destination of stabilized or reduced waste
Incineration by-products
slags
fly ash
flue gas cleaning products
other residues do undergo solidification
