Scheduled waste management
Category of health effects
Acute effect
Immediate effect, short duration of exposure, high dose.
Reversible, however, may be fatal if dose is very high.
Eg. irritation, skin burn, nausea, dizziness, and cardiovascular failure (cyanide poisoning).
Chronic effects
Delayed effect, repeated/long duration of exposure (months/years) to low dose.
Irreversible.
Eg. cancer, birth defects, infertility, neuropathy.
The rapid development of industrial in Malaysia have contributed in tremendous economic contribution to the country
But these sectors and their production activities have led to generation and accumulation of waste materials, including toxic and hazardous wastes
This caused a number of environmental related problems surfaced parallel to development efforts.
Regulations on Scheduled waste
Environmental Quality (Scheduled Wastes) Regulations 2005
Environmental Quality (Prescribed Conveyance) (Scheduled Wastes) Order 2005
Environmental Quality (Prescribed Activities) (Environmental Impact Assessment) Order 1989
Environmental Quality (Prescribed Premises) (Scheduled Wastes Treatment and Disposal Facilities) Regulations 1989
Environmental Quality (Prescribed Premises) (Scheduled Wastes Treatment and Disposal Facilities) Order 1989
Characteristics of scheduled waste

Labeling of scheduled waste
Must include the date of waste generated, name, address and telephone number of the waste
Symbolic labels (Third Schedule)
Waste code (First Schedule
Waste generator shall keep an inventory of scheduled waste
Accurate and up-to-date inventory must be maintained for at least 3 years.
Storage limit must comply with:
180 days from the date the waste was generated, provided the quantity is not more than 20 tonnes.
Cosignment note
Regulation 12
Notify the movement of wastes as required by sixth schedule of Regulation. Times of delivered and received wastes must be recorded accordingly by waste generator, contractor and receiver.
Notify the movement of wastes through consignment note
consists of 5 copies
waste generator
authority
waste facility/ receiver
waste generator
waste transporter
Safe Transport of Waste
carried by prescribed vehicle only(licensed by DOE)
Duty to ensure wastes are fit for carriage
Competent driver and worker
Emergency response plan
Spill & Accidental Discharge
Regulation 14
Inform rapidly to DG
undertake the studies on impact of discharge
provide technical expertise and support to the contractor in any clean up operation
Conduct Training
Ensure employees have adequate training on identification, handling, storing,labelling
Compounding offences
Compounded RM2000/offences
Hazardous Waste Management
Also known as “manufacturing process wastes,” and can be divided into seven categories
Spent solvent wastes
Wastes from Electroplating and Other Metal-Finishing Operations
Dioxin-Bearing Wastes
Wastes from the Production of Certain Chlorinated Aliphatic Hydrocarbons
Wood Preserving Wastes
Petroleum Refinery Wastewater Treatment Sludges
Multisource Leachate
When categorizing hazardous waste, the EPA breaks it down by four characteristics
ignitability, or something flammable.
corrosivity, or something that can rust or decompose.
reactivity, or something explosive.
toxicity, or something poisonous.
Workplace Regulations
Occupational Safety and Health Administration regulations require these protections.
Employees who may come into contact with hazardous materials must be fully trained in proper handling of these materials and equipped with all necessary protective gear such as gloves, goggles and coveralls.
Environemental Consequences
n serious health problems for those who consume contaminated water, air or food
cancer, nerve damage and birth defects
Verification by DOE
Improper storing
Hazardous Waste Management: Current status in Malaysia
Introduction
used materials now are seen as valuable resources.
it can be a source of living for many people
Recycling, composting of waste materials, generating energy from waste converting waste to other useful resources
sanitary landfill creates continuous environmental issue as more land needed to cater the increase in waste generation
disposal ativities require high cost and other problems such as odour, leachate
the traditional management tools are not sufficient under the present circumstances.
Overview of the current status of hazardous waste management in Malaysia
Industry and economic growth development
Has established a rapid growing manufacturing sector that plays an important role in economy.
industrial sector consisted of oil refining, machinery assembly, and light industries
become an important producer of radios, TVs, stereo equipment
in 1980's launched its national automobile project and started to export to international market in late 1980's.
in 1990s, growth in export-oriented electronics production including semiconductors, silicon wafers.
infrastructure ad utilities are developed to support industrial development and their capacity has increased.
the service sector was established to ensure industrial development wee met and sustained.
number of factories is increasing every year
But industrial waste production during extraction of resources, production processes and use by consumers has never been placed in manufacturing design.
Rapid economic growth and stability brought economic prosperity to a large proportion of population.
Hazardous waste in Malaysia perspective
Problem of hazardous waste in Malaysia:The control of airborne and waterborne toxic residuals does not address major issues if large quantities of hazardous materials after production.
DOE have the authority to define which one is hazardous or scheduled waste.
