Centralized Consolidation System that Overviews overall Hazardous Waste Management Process

All waste generated are subject to strict rule and regulation. These laws are binding to all waste management stakeholders from waste generator to the point of how the waste is securely disposed.

The continued increase in waste generation in Malaysia has been associated with the growing population and the growing economy. These factors create high demand for goods and services by the growing classes of people with an aim to meeting their varying lifestyles, while the environment bears the consequence of the increasing waste generation. The waste generated is projected to be 30,000 tons/day of waste generation by 2020.

According to the Malaysian Department of Environment, waste is defined as “any substance prescribed to be scheduled waste or any matter whether in a solid, semi-solid, or liquid form, or in the form of a gas or vapor, which is emitted, discharged, or deposited in the environment in such volume, composition, or manner as to cause pollution”.

Environmentally hazardous substance (EHS), under the Malaysian Environmental Quality Act (EQA) 1974, is defined as “any natural or artificial substances including any raw material, whether in a solid, semi-solid, or liquid form, or in the form of gas or vapor, or in a mixture of at least two of these substances, or any living organism intended for any environmental protection, conservation, and control activity, which can cause pollution”

Hazardous waste management during the boom in the manufacturing sectors was unsuccessful because no regulation was in place; thus, there were no comprehensive hazardous waste management facilities in Malaysia. industrial wastes were disposal freely into refuse disposal sites which were unsuitable as destinations for hazardous waste without proper treatment. The improper disposals led to poor air quality near the disposal sites, contamination of ground water, and surface water bodies by chemical and biological agents from the waste dumps/disposal sites causing adverse effects on human health and the environment.

The waste management facilities used by the various waste management operators in Malaysia depend on the waste that the operators handle. Below is the current hazardous waste management facilities used in Malaysia

  • Scheduled/hazardous waste transport facilities.

  • Off-site waste storage and waste transfer stations/facilities.

  • Secure landfill—for final disposal of stabilized wastes.

  • Scheduled waste incineration plant which can be on-site or off-site activities depending on the type of waste and volume generation.

  • Clinical waste incineration—specifically for the management of clinical and pharmaceutical wastes.

  • Off-site physio-chemical waste treatment facilities for waste stabilization or solidification for final landfilling.

  • Centralized waste treatment facility (e.g., electroplating park).

  • Resource recovery—this involves the recovery of reusable materials from hazardous waste such as oily wastes, metal dross/metal hydroxide, and catalyst.

  • Land treatment—treatment of contaminated land.

  • Waste water/sewage treatment facilities.

The complexity and tight regulation of hazardous waste management process made the process to oversee the whole process to be very hard and time consuming. Therefore, in order to properly protect the environment from harmful waste generated. Government needs to have a tool to track and make sure that proper process is done by licensed party. 

The system function as the single portal for each licensed party from generation, storage, handling, treatment, and final disposal to be able to act according to the set rule and regulation of hazardous waste management. Therefore, the government can easily manages and makes sure the waste generated are properly disposed and treated. 

In Conclusion

The dangerous effect of improper hazardous waste disposal can lead to long term damage to environment and people lives. The strict regulation that is put by the government can be more effective and efficient with the implementation of consolidating system that enables its users to manage all aspects of hazardous waste disposal.
