The practice of Karang guni is common in Singapore. Its practitioners are a modern form of rag and bone men that visit residences door-to-door. They can either walk along corridors (if that particular HDB estate has a covered carpark) or for certain HDB estates where the carpark is right under the HDB blocks, walk through the carpark downstairs honking a horn. However, around landed properties, they may drive around in a lorry with a horn attached to it, instead of going door-to-door. They make visits in carts, collecting old newspapers and other unwanted items. These will be resold at specialized markets and eventually recycled or reused. "Karang guni" is a Malay phrase for gunny sack, which was used in the past to hold the newspapers. The Karang guni men would haul the heavy sacks on their backs as they walked their rounds to do the collection. Today, most of them use a hand truck instead.
