How collection works
From first enquiry to disposal notification. “WG” means waste generator, the company that produces the waste.
Before collection
- The WG tells Petrojadi it wants to subscribe to our services.
- The WG sends a waste sample to Petrojadi for preliminary evaluation and analysis.
- The WG opens an account by signing the SWTTA or SWRRA agreement, and the TWG.
- Petrojadi returns the signed SWTTA or SWRRA to the WG.
- Petrojadi sends a preliminary quotation and advises the recycling and recovery (R&R) cost, either for waste buying (WB) or waste charging (WC).
- When the waste is ready, the WG contacts Petrojadi to arrange transport.
Collection
- The WG packs and labels the waste, or asks Petrojadi for packaging services.
- Once a collection date is agreed, Petrojadi sends a Collection Transportation Instruction (CTI) for the WG to acknowledge. On confirmation, Petrojadi instructs the Waste Management Centre (WMC), and the WG prepares the E-Consignment Note (E-CN).
- Petrojadi collects the waste at the WG's premises and transports it to the WMC. The WG is then notified through EIWIS of the status of treatment or disposal.
Conformity test and payment
After collection, Petrojadi runs a conformity test on the waste. What happens next depends on whether the waste has value (waste buying) or a cost to treat (waste charging).
Waste buying
Petrojadi issues a Waste Reception Treatment Report (WRTR) to the WG. The WG invoices Petrojadi for payment, and a copy of the consignment note is returned to the WG within 30 days.
Waste charging
If the WG agrees with the conformity test, waste declaration or sample test result, Petrojadi invoices the WG within 15 days. A copy of the consignment note is returned within 30 days.
If the result differs, Petrojadi advises the WG of the test result and cost for its consent. If the WG objects, Petrojadi returns the waste and the WG bears all costs incurred.

Packaging
Proper packaging is vital for safe transport and handling of hazardous waste. The waste generator is responsible for the correct packaging, labelling, transportation and specification of the waste, as set out in the Environmental Quality (Scheduled Wastes) Regulations 2005.
Packaging must be durable, compatible with the waste and able to withstand transport by lorry. It must be leak-proof, and the container must not be weakened by bulging, corrosion or tear.
| Container | Suitable for | Condition required |
|---|---|---|
Bunghole drum (steel or plastic) | Inorganic or organic liquid waste. Do not use steel drums for corrosive waste such as acids or alkalis. Plastic drums suit most solvents, but solvents such as diethyl ether and chloroform should go in steel drums. | No hole, no bulge, free of dent and corrosion |
Open top drum with cover and clamp (steel or plastic) | Solid waste, for example sludge, e-waste, pharmaceutical and laboratory waste, contaminated gloves. Do not use steel drums for acidic or alkaline waste. | No hole, no bulge, free of dent and corrosion |
Intermediate bulk container (IBC) | A broad range of waste streams such as oils, solvents and acids. | No hole or crack |
Jerrican or carboy | Inorganic or organic liquid waste such as chemical wastes and solvents. | No hole or crack |
Clinical waste container | Clinical and pathogenic wastes. | No hole or crack |
Corrugated or carton box | Dry, solid waste with no free-flowing liquid, in small quantity, for example e-waste, contaminated rags, expired drugs, cosmetics. | No tear or hole |
Flexible intermediate bulk container (FIBC / jumbo bag) | Dry, solid waste with no free-flowing liquid, for example dust, slag, ash, clinker, e-waste, dry sludge, contaminated rags, garnet. | Preferably high density polyethylene (HDPE), double lined, filled to no more than 90% |
Standard packaging
- Bunghole drum, for liquid waste. Maximum height 90 cm, diameter 60 cm. Fill to no more than 90%. A filled drum must not weigh more than 200 kg.
- Open top drum with clamp, for solid waste. Maximum height 90 cm, diameter 60 cm. Fill no closer than 10 cm from the top. Not for free fluids.
- One-tonne polypropylene (PP) bag. Must be double-lined. Fill no closer than 10 cm from the top. Not for free fluids.
- Pallet. Fasten all drums and bags securely on a good-condition pallet of 120 cm x 120 cm: four drums per pallet, or one PP bag per pallet. Secure drums with plastic or steel tape or band, in one stack.
Choosing by waste type
- Liquid organic or inorganic waste: bunghole drum (steel or plastic) or plastic pallet tank with stopper.
- Solid waste and empty contaminated containers: open top drums with covers and clamp.
- Dry solid waste and contaminated rags: one-tonne PP bags.
- Pharmaceutical and laboratory waste: open top drums with cover and clamp.
Lorry loading
| Lorry | Pallets |
|---|---|
| 3 tonne | 3 |
| 8 tonne | 10 |
| 12 tonne | 12 |
| 20 tonne | 18 |
Double stacking is allowed provided the total net weight does not exceed the vehicle's permitted weight.
Labelling
Labelling must follow Regulation 10 of the Environmental Quality (Scheduled Wastes) Regulations 2005. Warning labels are available from Petrojadi.
- Remove or erase all obsolete marks and hazard labels.
- Mark the side of the package with: name of waste generator; address and telephone number of waste generator; warning label; scheduled waste code; date of first waste generation; and consignment number.
- The label is square, set at an angle of 45 degrees (a diamond), and at least 10 cm by 10 cm unless the container is too small.
- It may be a stick-on, a metal plate, or stencilled or printed on the container.
- Labels must withstand open weather without substantial reduction.
- If waste has two or more hazards, identify all of them clearly and label accordingly.
- All markings must be clear and easy to identify.
Example marking
| X 123456 | X is the waste group, 123456 is the consignment code number |

| C | Waste solvents containing halogens and/or sulphur below 1% | Acetone, alcohol (ethanol, methanol), benzene, turpentine, xylene. Waste should be pumpable, with under 50% water, 18 MJ/kg calorific value |
| H | Organic chemical waste containing halogens and/or sulphur below 1% | Glue, latex, paint, phenol, printing ink, synthetic oil, soap, epoxy |
| K | Waste containing mercury | Mercury, vapour lamps, COD fluids, mercury batteries |
| T | Pesticide waste | Insecticides, fungus and weed killers, rat poison |

| Z | Miscellaneous | Medicine waste, lab-packs, asbestos waste, mineral sludge, isocyanate (MDI, TDI), batteries |
Waste oil
Lubricating oil needs replacing at intervals, so engines, machinery and vehicles are a continuing source of waste oil. Other sources include machining and cutting oil emulsions, tank washings and sludges from storage tanks and refineries, oily bilge and ballast water, and oil from electrical equipment such as transformers and capacitors.
Waste oil can contain metals, chlorinated hydrocarbons and other organics that harm people and living organisms through inhalation, ingestion or skin contact. Oil from electrical equipment needs special care because it may contain polychlorinated biphenyls (PCBs), which are persistent, toxic and need a different regime of control and disposal.
Waste oil codes
- SW305: spent lubricating oil
- SW306: spent hydraulic oil
- SW307: spent mineral oil-water emulsion
- SW308: oil tanker sludges
- SW309: oil-water mixture such as ballast water
- SW310: sludge from mineral oil storage tank
- SW311: waste oil or oily sludges
- SW312: oily residue from automotive workshop, service station, oil or grease interceptor
- SW314: oil or sludge from oil refinery or petrochemical plant
Waste oil that still has economic value can be recovered by facilities licensed by the Department of Environment (www.doe.gov.my). Recovered or recycled oil that does not meet the required standard is still scheduled waste.
