Property managers yesterday collected cash vouchers and certificates as reward for their efforts to make public housing estates greener places to live.
Over 130 estate management staff collected their prizes at the Housing Authority's second Green Property Management Awards.
The initiative is to encourage better management and co-operation between estate staff, tenants and the government in promoting and implementing green initiatives.
The winner of the Housing Department Category was Butterfly Estate in Tuen Mun, so named because of the abundance of butterflies in the area 20 years ago.
The winning estate features sculpted shrubs, recycling corners, bamboo gardens and conservation information stations.
There is also an education corner where residents can learn about different butterfly species.
Other efforts include use of organic fertilisers to grow plants and putting sand-filled water bottles in toilet tanks to reduce the amount of water used for flushing, said housing manager Chin Tak-kout.
