Annual Report 2020

70 Transport International Holdings Limited 2020 Annual Report Sustainability Report Energy Consumption To reduce fuel consumption, a number of measures have been adopted on the KMB and LWB bus fleets and across its operations: The aircraft-style “Posilock” fuel filling system is used to refuel buses; Ambient sensors are installed on air-conditioned buses to save energy by reducing unnecessary cooling; The use of synthetic gearbox oil extends the oil drain interval from 30,000 to 150,000 km, reducing waste oil by 80%; and The mileage-based oil change scheme brings about a 40% reduction in engine oil consumption and waste oil. Electricity Consumption We continue to explore environment-friendly initiatives and invested in the latest technologies to minimise energy use and reduce greenhouse gas emissions. Over 600 fluorescent tubes, flood lights and spot lights were switched off in the main depots. After the implementation of these saving measures, the depots reduce its total electricity consumption by around 6%, we have re- arranged the operation period of the air-conditioning units at depots, which has reduced the electricity consumption in that depot by around 2%. Through cooperation with a power company, a Solar Photovoltaic System consisting of more than 300 solar power panels has been installed on the roof of the Tuen Mun Depot. KMB will gradually introduce the system in major and satellite depots to strengthen the application of renewable energy and reduce greenhouse gas emissions. Water Consumption and Waste Water Treatment KMB and LWB as responsible corporate citizens are committed to reducing water consumption and properly treating effluents before discharge. Our depots are equipped with 10 automatic waste water treatment systems handling 400 cubic metres per day. The water used for bus washing was collected and recycled, bringing a reduction in total water consumption at depots of around 4%. However, owing to the COVID-19 pandemic, the total water consumption increased by 9.86% compared to 2019. More than 300 solar panels have been installed on Tuen Mun Depot’s rooftop for promoting the application of renewable energy With the environmental- friendly design, the automatic waste water treatment systems properly treat effluents Total Water Consumption of KMB & LWB # 80 60 40 20 0 20’ 19’ 18’ 74 71 + 80 m 3 /bus # The Water Consumption in all KMB and LWB premises, excluding tenants, were taken in account + Refer to GRI Standards 102-48, Restatements of information
