Hong Kong Aircraft Engineering Company Ltd 香港飛機工程有限公司 Engaging Sustainability Through Wastes Conversion HAECO fully understands that climate change will bring energy crisis to the company and community. Therefore, HAECO is dedicated in providing high quality aircraft maintenance services and at the same time, committed to reduce the environmental impact caused by the aviation industry. They are endeavour to achieve sustainable development by reducing waste and carbon emissions and using water sources efficiently. HAECO was awarded the Gold Award of the manufacturing sector with their multiple outstanding projects: the aircraft exterior dry wash technique, waste conversion system and the patented long-range Wide Area Network. 轉廢為能 持續發展 港機工程清楚了解氣候變化會為公司及其 營運地區帶來嚴重風險。因此，他們除了全 力以赴提供優質飛機維修服務外，同時亦採 取積極行動來減少碳排放、廢物產生及耗水 量，以減輕航空工業對環境的不利影響，確 保未來業務可持續發展。憑藉其卓越的飛機 乾洗技術、廢物轉化系統及專利的遠程廣域 網（LoRaWAN），令港機工程再下一城，榮 獲大獎（製造業）金獎。 港機工程的飛機乾洗服務比傳統水洗可節 省多達九成用水，且有助縮短飛機於地面停 留的時間，節省能源消耗及碳排放。集團環 境經理鄧伙勝解釋：「飛機乾洗不但可節省水 源，乾洗劑不含受限制的成分，並且可以完 全達到生物降解，更可以令機身表面潔淨， 大減空氣阻力，降低飛行中的燃油消耗，一 舉兩得。我們經過多番努力與不同航空公司 洽談，成功令此乾洗服務被廣泛使用。」 為充分利用剩餘燃料並減少液體化學廢 物，港機工程最新開發的廢物轉化系統可將 此類燃料再用於吸收式製冷機組，以產生冷 量為中央冷卻器系統供水，預計每年可消耗 2.6萬升航空燃料及節省約30萬港元的化學 處理成本。 此外，其專利的遠程廣域網可實 現超長距離傳輸，同時高效減低碳排放量。 The aircraft exterior dry wash technique uses 90% less water than the traditional “wet wash” method, and also improves operational efficiency by shortening the towing time, lower fuel consumption and carbon emissions. Matthew Tang, Group Environment Manager, says, “This aircraft exterior dry wash technique not only saves water resources, it also keeps the aircraft surface clean which lower jet fuel consumption by reducing the drag in flight. The dry wash detergent does not contain any restricted substances and could be completely biodegradable. With all these advantages and company’s effort in exploring its application to different airline customers, this eco-friendly technique has been widely used.” HAECO’s latest development turns waste into energy, this system is to reuse the spent aviation fuel and absorption chiller to generate cool water for feeding the central chiller system. This can fully utilise the left-over fuel and reduce liquid chemical waste. This recycling system could reuse 26,000 litres of aviation fuel annually and saves chemical disposal cost around HK$300,000 per year. In addition, the patented digital wireless data communication technology, Long Range Wide Area Network, enables transmissions within a very long range which could effectively locate ground service equipment and minimise unnecessary carbon emissions.
