Hong Kong's Science and Technology Parks in Sha Tin will strive to attract companies that can develop overseas environmental technologies for applications on the mainland and in the rest of Asia, the parks' top executive says. The parks would also push to lure energy management companies to tap the region's growing market in power conservation and energy efficiency, corporation chief executive Anthony Tan said. It is all part of Hong Kong Science and Technology Parks Corporation's strategy to develop green technologies as its fifth cluster, after information technology, biotechnology, precision engineering and electronics and semi-conductors. Mr Tan said one of the key tasks now was to recruit green technology companies that would set up research and development bases. 'We will attract people whom we call integrators who can licence, introduce or develop technologies from developed countries like Europe or the United States in water treatment or air purification technologies or processes to reduce pollutants,' Mr Tan said. 'We can become the integrator of technologies for applications in China or Asia, as some of these technologies might not be able to be applied unless you know how to use them locally. I know Hong Kong has the engineering capability to do this.' Given rising global concern over climate change and government support for energy efficient buildings, companies focusing on energy management would also be welcomed, Mr Tan said. 'High-rise buildings in Hong Kong account for about 90 per cent of electricity consumption,' he said. 'If we can manage the energy inside the building, like cutting it by 10 per cent, it will have a big impact.' The park also planned to turn one of the buildings into a showcase for energy-efficient building technologies, and an education centre would be set up to demonstrate the benefits. Mr Tan said the science park would also continue to attract companies specialising in renewable energy with a focus on solar energy. Hong Kong's status as a a financial and trade hub with sound intellectual property protection and its close proximity to manufacturing bases in the Pearl River Delta would help it overcome rivals like Taipei or Singapore to lure technology companies. 'It is a successful business model which is hard to compete against,' Mr Tan said. More than 200 companies are now based at the Sha Tin park, employing 6,000 people. Park managers say the park will employ more than 12,000 people when its third phase is completed in 2013.
