HAZARDOUS WASTE PRODUCTION IN MALAYSIA
HAZARDOUS WASTE MANAGEMENT FACILITIES
Waste recovery facility
Recycling facility
Treatment facility
Fully integrated facility (Kualiti Alam Sdn Bhd, Faber Medi-Serve Sdn Bhd, Pantai Medivest Sdn Bhd, Radicare (M) Sdn Bhd )
Incineration plant
Physio-chemical treatment plant
Solidification plant
Secure landfill
Kualiti Alam treats 120 000 metric tons of Malaysia's industrial waste per year
Ash produced 14000 metric tons which disposed to secured landfill
Facility has capacity 15000 metric tons per year
To separate hazardous materials to less harmful materials
Constructed with some monitoring sensors in order to prevent ground contamination
In 2014, schedule waste generated decrease from 1880.9 tons to 1665.3 tons compared 2010

-address
-phone number generator
Handle all types of inorganic liquid waste
Zero emission
system and has no harmful effects compared incenerator
Does not
involve combustion and does not produce water, steam, odour, and smoke
Can process the maximum quantity of 300kg per hour and the residue
can be placed in the landfill.

scheduled wastes had been treated, it will be placed in the secured landfill.
CHALLENGES OF SCHEDULE WASTE IN MALAYSIA
The cost dispose schedule waste quite expensive
Lots of illegal dumping cases
Worst case in Malaysia was Sungai Kim Kim occurred in March until August 2019
Chemical detected were methane, toluene, xylene, ethylbenzene, and D-Limonene
Lead to acute poisoning
Improper knowledge on scheduled waste handling
lack of transfer station for waste
management
No proper disposal mechanism that has been introduced for e-waste discarded properly in Malaysia
Illegal dumping increases from year to year
