Two new waste-handling stations are to be built to process construction debris. The move is part of the Government's efforts to meet ambitious recycling targets. The stations, at Tseung Kwan O and Chai Wan, will be built at a cost of about $50 million and are expected to separate debris into reclamation materials and regular refuse for disposal. Without the separation, mixed construction debris would be sent to landfills which could not be recycled, Deputy Secretary for Planning, Environment and Lands Kim Salkeld said yesterday. Unmixed construction waste is sent to public filling areas for reclamation. 'The new facilities are part of the process to increase the recycling rate and to put less unnecessary materials into landfills so we can extend their use cycles,' he said. About 79 per cent of construction waste is being recycled, mainly for reclamation, but the Government hopes to raise the figure to 84 per cent by 2003. Currently, only one waste-separation station operates in south-east New Territories. The Tseung Kwan O station is expected to be ready by the middle of 2000 while Chai Wan will be operational in 2002.
