As part of the Carbon Management Plan, until the end of 2022, MIA had replaced and purchased eight hybrid and three electric vehicles.
Food Waste Recycling Programme
MIA implemented the Food Waste Recycling Programme since 2013. In the past years, the Food Waste Composter treated the food wastes generated from the uneaten in-flight meals and the food wastes from staff canteen in Servair Macau and the food wastes from Airport Restaurants, Plaza Premium Lounge and coffee shops in PTB. Until the end of 2022 the Food Waste Composter had recycled over 112,000 kg of food wastes and turned them into organic compost, which were used for grass growing near the Runway area by Landscaping staff. This had helped to reduce the amount of wastes sent for incineration.
Green the Airport with Various Plants
All kinds of plants are located in different areas of the terminal building, namely: Calathea Makoyana, Rhapis excelsa, Fagraea ceilanica, Schefflera arboricola and Dracaena “Lemon Lime” placed in departure lounge. The plants rotate every season. Green plants can reduce emission of carbon dioxide, purify air and improve air quality, MIA determine to provide a memorable green airport experience for the all passengers!
Replacement of Airfield Ground Lighting (AGL)
Since 2013, with the subsidy from Environmental Protection and Energy Conservation Fund of Macau SAR Government, MIA had replaced the traditional Taxiway Edge Lights, Stop Bars, Taxiway and Apron Centre Line Lights. Since 2017, CAM had also invested in replacing the Sequential Flashing Lights (SFL) and Runway Threshold Identification Lights (RTIL) on both Runway 16 and 34 with LED ones. After the replacement of the abovementioned AGLs, over 16,000 kg of carbon emissions can be reduced.
Replacement of Chillers to Energy Efficient Models
In 2022, MIA had replaced the aging chillers with energy efficient models. After the replacement of chillers, total electricity consumption had decreased 11% in 2022 compared to that of 2021. These chillers consume more environmental-friendly type of refrigerant, which has a lower global warming potential than the type of refrigerant used for the previous chillers, therefore contributed to reduced carbon emissions.
