Total Green Area
To reduce heat island effect, lots of green is arranged.
Rooftop Gardening
Waste is separated into 20 different classifications in the buildings.
Waste generated daily is separated into 20 different classifications and 17 of these items are recycled.
17 items: Recycle
2 items: Thermal Recycle
Food, fish, oil, polystyrene form, news paper, magazine, copy paper, cardboard, etc.
Food waste, other burnable trash
1 items: LandfillOther non-burnable trash
