Annual Report 2025

67 2025 Annual Report Transport International Holdings Limited About the Report Safety First Caring for the Environment Caring for Customers Caring for Employees Caring for the Community Performance Statistics Reporting Content Index Table Energy Saving KMB and LWB implement a range of measures to reduce resource consumption and streamline waste-management procedures. All materials are handled and disposed of responsibly, in full compliance with relevant laws and regulations, ensuring no risk to human health or the environment. Fuel Across KMB, LWB and Sun Bus operations, several initiatives have been adopted to enhance fuel efficiency and reduce waste: Aircraft-style “Posilock” refuelling system: Helps shorten idling time during refuelling, lowering fuel consumption; Ambient sensors for air-conditioned buses: Reduce unnecessary cooling and improve overall fuel efficiency; Synthetic gearbox oil: Extends oil-drain intervals, reducing both oil use and waste-oil generation; Mileage-based oil-change scheme: Further reduces engine-oil consumption and waste; and Use of Biodiesel B5: Selected Sun Bus services use Biodiesel B5, a renewable fuel produced from animal fats and vegetable oils, to reduce carbon emissions and overall environmental impact. Electricity We continue to explore environmentally-friendly initiatives and invest in advanced technologies to reduce energy consumption and minimise greenhouse gas emissions. Beyond the one-off replacement of LED lighting and ongoing housekeeping measures, we have also adjusted our electricity-use patterns in line with operational needs, for example, optimising illumination schedules at parking depots and enhancing the efficiency of equipment supporting our facilities. Green Measures in the Office The green office concept guides the design and renovation of our premises. We maintain indoor temperatures at 25.5°C in support of the HKSAR Government’s Action Blue Sky Campaign and have adjusted operating hours to avoid unnecessary energy use outside office hours. All newly renovated offices are equipped with high-efficiency air-conditioning units. Recycling systems are in place for used toner cartridges, paper, and plastics, and regular awareness initiatives are conducted to encourage good housekeeping practices among staff to further promote energy saving. Waste Reduction KMB and LWB are committed to responsible waste management, including proper storage, disposal, recycling, and reuse of resources wherever feasible. The major types of waste generated in our operations are managed as follows: Wastewater KMB and LWB strive to reduce water consumption and ensure all effluents are properly treated before discharge. Our depots operate nine automatic wastewater treatment systems with a combined capacity of 400 cubic metres per day. Recycled water from bus-washing operations has helped reduce total depot water consumption by around 4%. Several satellite depots also incorporate rainwater collection and water-recycling systems. Tyres and Metals Used tyres from KMB and LWB are retreaded by appointed contractors, while metal waste is sent to licensed recyclers for processing. Oil and Chemicals Solid chemical waste is classified and stored in designated areas at bus depots before being collected by registered contractors for treatment at the Hong Kong SAR Government’s Chemical Waste Treatment Centre. Waste oil is recycled or disposed of in accordance with statutory requirements. During the reporting period, KMB and LWB further reduced solid chemical waste by extending engine-oil drain intervals. Batteries are handled by licensed contractors in compliance with Environmental Protection Department (EPD) requirements, with some exported to EPD-approved overseas facilities under the Basel Convention.
