ENVIRONMENTAL, SOCIAL AND GOVERNANCE PERFORMANCE (Continued) 3.1 Environment (Continued) 3.1.2 Use of Resources (Continued) Water Conservation Measure (Continued) In the process of manufacturing containerboard, lots of wastes and useful fibers would be extracted from waste paper. Parts of the useful fibers would be retained in water (“White Water”). The Group has adopted the reuse of White Water at the Qingyuan Factory. After processing through the White Water recycling system, wastewater reaching the standards would be returned to the production lines for use in order to minimize wastewater generation and water consumption. Moreover, it has also been equipped with effective wastewater treatment technique, a n a e r o b i c d i g e s t i o n . Wi t h t h i s f a c i l i t y a n d technology, the Group has greatly reduced water consumption and hazardous substance in the wastewater. The thermal power station has been equipped with cooling system so that condensed wa t e r c ou l d b e r e c y c l e d f o r t he bo i l e r u s e . Technological upgrade to the facilities has increased the rate of reusing water and reduced the volume of wastewater emission. Office Resource Conservation T h e G r o u p a c t i v e l y p r o m o t e s e l e c t r o n i c documentation to implement the concept of a paperless office. Computer files are used instead of hardcopies to reduce the use of paper in offices. The Group also encourages employees to adopt other recognized management practices to avoid excessive use of resources by the Hong Kong and Qingyuan offices such as (1) re-usable eating utensils instead of disposable ones, (2) using single-side printed paper as draft paper, (3) encouraging double-side printing, (4) collecting waste office paper for recycling, and (5) collecting and returning empty ink cartridges to the qualified licence suppliers for recycling. Concurrently, those scrap paper and confidential documents must be shredded and stored at the recycling station, and finally passed to the qualified licence recyclers on a regular basis.
