Lead to acute poisoning
Illegal dumping increases from year to year
Factors
Economy
Demand
Living standard
Population growth
Industrial and urbanization
Table statistic illegal dumping activities in Malaysia 2015
Improper knowledge on scheduled waste handling
lack of transfer station for waste
management
