Singapore and Japan could provide useful lessons about waste reduction and incineration, Chief Executive Donald Tsang Yam-kuen said. Mr Tsang returned yesterday from a three-day visit to Singapore, where he learned about its latest efforts in environmental protection, health care and tourism. In a blog entry titled 'Rubbish - Risks and Opportunities', Mr Tsang wrote he was surprised to learn that 60 per cent of the waste in Singapore was incinerated, while Japan burned 67 per cent. 'What intrigues me is that incineration has been widely accepted by people in both places. Is there anything we can learn?' he wrote. The government faces stiff opposition to a proposal to use incinerators to ease the burden on landfills. Mr Tsang warned that recycling and waste reduction would not be enough to effectively keep the ever-increasing amount of rubbish under control. Recalling his visit to Tuen Mun West last week, Mr Tsang said he was shocked by the sheer size of the landfill there. 'Some 100 metres in height and the size of a football pitch, it was just like a big mountain. 'Waste management is an urgent task which brooks no delay. We could plan ahead early in a pragmatic way by drawing reference from these places,' he said.
