34 HOP FUNG GROUP HOLDINGS LIMITED • Annual Report 2021 ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT (CONTINUED) 環境、社會及 管 治報告(續) 3. 環境、社會及管治表現 (續) 3.1 環境 (續) 3.1.1 排放物 (續) 透過實施上述減少廢棄物的 政策及措施,集團展示報告 期間的下列結果: 圖一 * 二零二一年度因政策禁止 進口廢紙,因此沒有產生 相關廢物。 減少大氣排放物 集團主要的氣體排放物源 頭為鍋爐釋出的廢氣,主要 包含煙塵、二氧化硫和氮氧 化物。同時,集團採用了不 同技術去控制氣體排放物: 於鍋爐排放的廢氣經煙氣濕 法空心噴淋塔,以鎂法脫硫 技術,減少煙氣中的二氧化 硫;採用 SNCR 脫硝技術降 低氮氧化物;以布袋除塵器 減低煙氣中的煙塵。 3. ENVIRONMENTAL, SOCIAL AND GOVERNANCE PERFORMANCE (Continued) 3.1 Environment (Continued) 3.1.1 Emissions (Continued) The Group has demonstrated the following results in the reporting period through the implementation of the aforementioned policies and measures for waste reduction: Figure I Total Annual Emissions (tonnes) 年度總排放量(噸) 2021 2020 Types of Wastes 廢棄物種類 二零二一年 二零二零年 Hazardous Waste 有害廢棄物 2 3 Non-hazardous Waste 無害廢棄物 –* 242 Waste Intensity per Employee (tonnes/person) 平均每位僱員所產生 廢棄物密度(噸╱人) 2021 2020 Types of Wastes 廢棄物種類 二零二一年 二零二零年 Hazardous Waste 有害廢棄物 0.01 0.01 Non-hazardous Waste 無害廢棄物 –* 0.43 * In 2021, due to the policy of suspending the import of waste paper, no waste was generated . Reduction in Atmospheric Emissions The main source of gas emissions for the Group comes from the boilers which mainly consist of soot, sulfur dioxide and nitrogen oxide. In the meantime, the Group utilized a variety of technologies to control the gas emissions: exhaust gas from boiler combustion is passed to the Wet Flue Gas Spray Tower for magnesium desulfurization to minimize t h e s u l f u r d i o x i d e i n t h e f l u e g a s ; S N C R denitrification technology is adopted to minimize nitrogen oxide; and the soot from flue gas is minimized through bag filters.
