ENVIRONMENTAL, SOCIAL AND GOVERNANCE REPORT 環境、社會及管治報告 HOP FUNG GROUP HOLDINGS LIMITED 合豐集團控股有限公司 34 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 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） 2019 2018 Types of Wastes 廢棄物種類 二零一九年 二零一八年 Hazardous Waste 有害廢棄物 3 3 Non-hazardous Waste 無害廢棄物 367 347 Waste Intensity per Employee (tonnes/person) 平均每位僱員所產生 廢棄物密度（噸╱人） 2019 2018 Type of Waste 廢棄物種類 二零一九年 二零一八年 Hazardous Waste 有害廢棄物 0.01 0.01 Non-hazardous Waste 無害廢棄物 0.63 0.59 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 the sulfur dioxide in the flue gas; SNCR denitrification technology is adopted to minimize nitrogen oxide; and the soot from flue gas is minimized through bag filters.
