We discharge water into nature in a clean and pure condition, that meets or exceeds legal requirements in almost every territory in which we operate. We are committed to wastewater treatment standards which require returning all water used in our manufacturing processes to the environment at a level that supports healthy aquatic life.
To further reduce our demand for freshwater, Swire Coca-Cola uses recycled wastewater. Bottling plants in Mainland China and Hong Kong have their own wastewater treatment systems. Treated wastewater is reused in cooling towers, cleaning, irrigation and toilet flushing. Backwash water from pump seal cooling lines and ozone generator cooling systems is reused in condensing towers.
In 2019, Swire Coca-Cola recycled 883.6 million litres of water, 192 million litres more than in 2017. Wastewater discharged from its bottling plants meets the water quality requirements of The Coca-Cola Company and the World Health Organisation. Performance is monitored and verified to ensure compliance with regulations. Internal wastewater is sampled daily and external wastewater annually. Swire Coca-Cola does not use recycled water in its drinks. In Mainland China, an online monitoring system to track wastewater compliance has been installed.
The bottling plant in Jinqiao, Shanghai, has upgraded their wastewater treatment facility, which has enabled them to reuse treated water. This is expected to save around 60 million litres of water annually.
At the Hangzhou bottling plant, final rinse water has been reused for cleaning since early 2019. In Yunnan, water metering has been installed to monitor and optimise water use.
The principal companies in the HAECO Group have wastewater treatment plants. HAECO Xiamen uses heavy metal monitoring equipment and detectors to check effluents before discharge. HAECO Xiamen uses treated wastewater for irrigation, vehicle cleaning, toilet flushing and apron watering. Taikoo Engine Services (Xiamen) uses treated water for toilet flushing. HAECO Group has 8% of water withdrawn being reused.
Cathay Pacific Catering Services collects condensate water from air handling units for use by chillers. This recovers 730 tonnes of water annually, representing 0.15% of its total water consumption, generates 9,000 kw/yr of electricity, and reduces CO2 by 4.6 tonne/yr.
At Swire Properties’ Brickell City Centre development, an elevated trellis provides shade from the sun, creates air flow and collects rainwater. At INDIGO, wastewater and rainwater are used for toilet flushing and irrigation. Recycling of sewage is planned, with a view to saving 85,000 tonnes of water annually. Recycled rainwater is used for irrigation at One Taikoo Place.
