Scheduled Waste Analysis in Malaysia
Scheduled Waste Testing and Analysis
Managing scheduled waste is a legal requirement under Malaysian law and an environmental responsibility for many. Our scheduled waste testing and scheduled waste analysis services help businesses accurately identify, classify, and manage their waste in compliance with the Department of Environment Malaysia (DOE).
We support manufacturers, factories, laboratories, workshops, healthcare facilities, and industrial operators across Malaysia with reliable laboratory testing and expert analysis to ensure safe handling, storage, transport, and disposal of scheduled waste.
What Is Scheduled Waste Analysis?
In Malaysia, scheduled waste refers to waste materials listed under the First Schedule of the Environmental Quality (Scheduled Wastes) Regulations 2005, such as chemical residues, heavy metal sludge, spent solvents, contaminated packaging, and oil-based waste.
There are 77 categories of scheduled waste as established by the DOE that requires proper management. Correct identification and permits are critical. Misclassification can lead to regulatory non-compliance, environmental harm, and penalties. That’s where professional scheduled waste testing and analysis become essential.
Depending on the waste type, testing may include analysis of:
- Heavy metals and toxic elements
- pH, corrosivity, and reactivity
- Organic and inorganic contaminants
- Oil, grease, and solvent residues
