The rapid industrial
development in Malaysia has created significant industrial waste pollution
problems which need immediate remedy. Industrial waste pollution has created a
lot of effluent.
Much of this effluent
contains toxic and hazardous waste. Management of industrial waste is a growing
concern in Malaysia. The waste if improperly segregated or disposed off can
cause dangerous results. This means that the proper management of such toxic
and hazardous waste requires discipline, vigilance and at times just common
sense.
The co-disposal of
toxic industrial waste together with household waste in landfill disposal sites
can cause potential release of toxic material into the environment through
leaching. Therefore, the best approach to waste management is not to produce
waste, but to produce less waste or to produce waste of reduced hazard. This
goal can be promoted in several ways, such as to apply proper waste management,
to select a process that inherently produces less waste, to recycle and reuse
generated waste and to select non-hazardous and less toxic material.
In Malaysia, the
control of hazardous waste is governed by the Environmental Quality Act passed
in 1974. A hazardous waste is a solid, liquid or gas that could pose dangers to
human health or the environment. Under the 1989 Environmental Quality
Regulations, scheduled waste is required to be handled properly. It can be
industrial, hospital and household waste. Currently, there are 107 categories
of scheduled wastes, listed under these regulations. These categories of waste
shall be disposed off at prescribed premises only and be treated at prescribed
premises or treatment facilities only. They have to be treated through some
microbial-based on-site processes to remove or detoxify the waste material.
Generally, the project
implemented, namely 'Leachate Treatment System Using Microbial Process' will
attempt to develop new microbial processes for waste treatment. This project
will look into bioremediation of solid waste in landfill sites and the effects
on groundwater and the environment.
The aims of the project
are to achieve cost-effective industrial wastewater management through new
approaches, the development of appropriate microbial treatment and
detoxification technologies and identification of resident microbes. The
benefits are comprehensive characterization and evaluation of leachate
generated from local landfill sites and identification of microbes.
The Leachate Treatment
System Using Microbial Process' project was one of the most comprehensive
studies to be conducted on local landfill leachate, which is a significant
source of aquatic pollution yet to be properly managed. The findings are
expected to provide the scientific and technical basis for the design and
operation of proper landfill leachate management systems in the future.
Meanwhile, new
guidelines passed on waste disposal have proved effective. They include
recommendations and procedures for handling and disposal of chemical waste from
laboratories in such manner that will not constitute a risk to human health,
safety or the environment. The guidelines outline the type of chemical waste
generated in laboratories, approaches in the minimization of chemical waste,
safety procedures in handling such waste, laboratory safety procedures and the
chemical waste disposal procedures.
To paint a brighter
picture, much progress has been made in waste disposal in the country. However,
a lot more still needs to be done for us to claim that the waste disposal
situation is safe for the people and the environment.
Summary: There is much
industrial waste in Malaysia. Much of this is toxic and dangerous. The waste if
improperly disposed off can cause dangerous results. Therefore, proper
management of such waste requires discipline and vigilance. The best approach
is to produce less waste or produce waste of reduced hazard. Hazardous waste
poses danger to human health and the environment. The 107 categories of
scheduled wastes have to be treated through some microbial-based processes to
remove waste material. The Leachate Treatment System Using Microbial Process
attempts to develop new microbial processes for waste treatment. The aims are
achieving cost-effective industrial wastewater management. New guidelines on
waste disposal have proved effective. They include recommendations and
procedures for handling and disposal of chemical waste from laboratories that
will not constitute a risk to human health, safety or the environment.
