Air Pollution Control Measures
| Emissions from diesel-driven cranes. |
 |
Preventative maintenance program are undertaken to reduce the dark smoke and improve the efficiency of all the diesel-driven cranes. Air emissions are checked in accordance with the planned maintenance schedule against requirements and rectified if found to be below the standard. |
| Vehicle emission |
|
EURO III engine equipped vehicle is the standard for all new company diesel vehicles. |
|
more fuel efficient (25% Dark smoke reduction & 5% fuel reduction). |
|
Research for hybrid vehicle system. |
| Indoor Air Quality |
|
IAQ monitoring audits have been carried out quarterly to monitor the indoor air quality. |
|
Installation of Primary Air Handling Unit (PAU) which increase the fresh air supply to the building by 40%. |
|
Waste water and Water Conservation
| Waste water generated from Container Stacking Yard |
|
Washing bays to collect emulsified grease water generated from crane and vehicle washing for off-site disposal. |
|
Petrol filling stations surrounded with independent drainage system to underground oil interceptor. |
| Waste water generated from Canteen |
|
Under-sink grease traps remove large chunks of grease. |
|
Application of Dissolved Air Flotation (DAF) system to separate/retrieve the oil from the emulsified grease before going to the sewage treatment plant for off-site disposal. |
|
O & G and COD level could be reduced significantly (Removal rate is 94% and 45% respectively. |
|
Waste Management and Resource Efficiency
| General solid wastes and recyclables |
|
Household waste - Different color coded recycling bins. |
|
Collection traps in our office for used envelopes (for internal mail) and scrap papers (for rough works printing). |
| Chemical waste |
|
Chemical Waste Collection Points. |
|
Centralized Chemical Waste Storage Compound. |
|
Recycling of lubricant and hydraulic waste oil by dynamic oil purifiers. |
|
Waste Minimization & Cost Saving in treatment and lube oil usage. |
| Industrial waste |
|
Waste Segregation for recyclable materials such as batteries, scrap metal, printer toners and tyres. |
|
Management procedures to reduce waste generation, such as: |
| |
- A write off procedure to control the disposal of materials.
- Use rechargeable batteries instead of non-rechargeable ones to minimize the disposal of batteries.
- Use solar powered appliances such as calculators to avoid battery disposal.
- Sell out/donate the old furniture, used appliances and old computers to charitable bodies. |
