Annual Report 2023

69 2023 Annual Report Transport International Holdings Limited Waste Reduction KMB and LWB are committed to good waste management through responsible storage and disposal of waste, recycling and reusing resources whenever feasible. Significant types of waste generated in our operations are reported as follows: Waste Water As responsible corporate citizens, KMB and LWB are committed to reducing water consumption and properly treating effluents before discharge. Our depots are equipped with nine automatic wastewater treatment systems handling 400 cubic metres per day. The water used for bus washing was collected and recycled, reducing total water consumption at depots by around 4%. Newly setup rainwater collection and water recycling systems have been introduced in some of our satellite depots. Tyres and Metals Used KMB and LWB tyres were retreaded by KMB’s appointed contractors, and waste metals were sent to recycling companies. Oil and Chemicals Solid chemical waste is processed and stored by type in designated areas at bus depots before disposal by a registered chemical waste collector at the Government’s Chemical Waste Treatment Centre, while waste oil is recycled or disposed of in accordance with the statutory standards. In the reporting period, KMB and LWB have improved the engine oil replacement cycle by changing new engine oil with extended oil drain intervals to reduce solid chemical waste. Batteries are disposed of by a licensed contractor complying with the instructions of the Environmental Protection Department (“EPD”), with some of them exported to overseas facilities approved by the EPD under the Basel Convention. The fleet is now using a new tyre model to extend the lifespan of tyres and reduce solid waste disposal
