Sustainability Report 2011
Saving Paper
The greater use of digital communication is increasingly seeing our transition into
a paperless operation. In addition to minimising the use of paper and ensuring it is
recycled in our day-to-day office pursuits, these endeavours are particularly visible in
our e-procurement and e-billing activities. The former reduces the need for paper both
among our suppliers and ourselves, while the latter not only saves paper, it also reduces
postage costs and saves the energy required to deliver these bills. With the launch
of a lucky draw to promote eBilling applications during the year, there were 59,676
registered eBilling customers at the end of 2011. This figure translates into the saving
of some 7.5 tonnes of paper annually.
Saving Water
In 2010, a new reverse osmosis water treatment facility was installed in our Tai Po
Plant. In its first year of operation, it saved more than 40,000 cubic metres of effluent
water as well as 65,000 kg of sulphuric acid and 96,000 kg of sodium hydroxide in
comparison to the previous facility.
In 2011, in view of the problems encountered with Legionnaire’s Disease in Hong Kong,
a major emphasis was placed on water quality. We participated in a territory-wide
Quality Water Recognition Scheme for Buildings and also completed a water quality
assessment at our headquarters, which confirmed that the disease was absent in our
water systems. Looking forward, we are also exploring the more efficient use of water
in our buildings, regulating the flow of water in toilets for example, and we are studying
the possibility of collecting rainwater at our production facilities, for the watering of
plants and other similar uses.
