Hong Kong has been allocating significant resources toward tackling air pollution, water pollution and solid waste treatment problems. Opportunities also exist in the areas of clean production, clean energy and energy efficiency.
Hong Kong plans to construct a new Integrated Waste Management Facility (IWMF). Two possible sites for the IWMF have been identified and a, pending feasibility review. The core technology of the IWMF will be waste-to-energy incineration (the first phase calls for a capacity of approximately 3,000 tons per day), supplemented by sorting and recycling technologies. The pre-qualification process for the construction of the waste-to-energy plant will start in the latter half of 2010 to meet a commissioning date in 2015.
Among the Hong Kong Government’s (HKG) waste management initiatives is the establishment of EcoPark, a facility dedicated to value-added waste recycling. Phase I of the EcoPark has been completed and is now handling the recycling of waste wood, used cooking oil, used computer equipment, waste plastics, waste metal and waste batteries. HKG is setting up two waste collections and recycling centers in Phase II of EcoPark targeting the recycling of waste plastics, and electrical and electronic equipment waste. Phase II is scheduled for commencement in mid 2010.
The majority of Hong Kong’s wastewater undergoes primary treatment through the Harbor Area Treatment Scheme (HATS). Stage 1 of HATS was completed in December 2001. Stage 2A of HATS requires the provision of additional disinfection, the construction of sewage tunnels and expansion of existing chemical treatment capacity. Stage 2B requires the installation of biological treatment facilities. Detailed planning is underway with the aim of completing Stage 2A in 2014. The timing of Stage 2B, to be undertaken in 2010-11, will depend upon a review of water quality trends, population increase and sewage flow build up.
Hong Kong’s air pollution problem is a regional one. The HKG has agreed with the authorities in mainland China’s Guangdong Province to cut emissions of major air pollutants, i.e., sulphur dioxide, nitrogen oxides respirable suspended particulates, and volatile organic compounds (VOC), to meet more stringent caps by 2010. Power generation is the primary source of local emissions of these pollutants. The HKG signed the Scheme of Control Agreements with the two Hong Kong power companies, Hong Kong Electric and China Light and Power, on January 7, 2008, which stipulated that the permitted rate of return for the power companies would be linked to their emissions performance. Both power companies have started their own overall retrofit programs, and the project will be completed in phases between 2010 and 2011.
In neighboring Macau, the local government recently expanded its waste incineration facility, tightened emission standards, built a hazardous waste treatment plant, set up waste classification and recycling stations, and expanded its wastewater treatment plant. In the ten years after Macau’s handover to China in December 1999, the Macau Government spent close to US$500 million investing in new environmental infrastructure and conservation projects, as well as operating existing environmental facilities.
Macau imports power from the China Southern Power Grid to meet almost 70 percent of its total power need. Locally, Macau will increasingly rely on natural gas for power generation in response to the public’s desire for cleaner air. CEM (the only power generation company in Macau) will gradually replace the existing heavy fuel generation facilities at the Macau Power Station with gas-fired generation units.
The mainland of China is the primary supplier of potable water to Macau. Owing to deteriorating quality, the Macau Government aims to gradually decrease the share of its water supply that comes from the mainland 11 percent by 2015, 20.3 percent by 2020 and, ultimately, 29 percent by 2025. To achieve this goal, Macau will encourage the utilization of other water resources, such as rainfall and recycled water. The Macau government also announced in January 2010 that it will start distributing water-saving devices free of charge to local small- and medium-sized enterprises (SMEs) in the first half of 2010.
• Analytical instruments
• Vehicle emission particulate reduction devices
• Desulphurization/de-nitrification technologies
• Water saving devices
• Water filtration equipment (such as biological filtration)
• Disinfection technologies (UV, membrane & ozonation)
• Analytical instruments
• Mechanical-biological treatment (waste sorting & separation)
• Biological treatment (composting)
• Waste-to-energy technologies
• Recycling technologies for handling batteries, tires, electronic goods, plastics and wood
The market for industrial pollution prevention equipment has been growing. The HKG and the Guangdong Provincial Government jointly launched the five-year Cleaner Production Partnership Program (CP3) in April 2008. Under this initiative, the HKG allocated about US$12 million to encourage more than 60,000 Hong Kong-owned enterprises and factories in the Pearl River Delta (PRD) region to adopt cleaner production technologies and practices.
The HKG also allocated US$58 million to subsidize residential, commercial, industrial buildings in Hong Kong to carry out energy audits (reviewing the use of energy and quantifying the greenhouse gas (GHG) emissions associated with the buildings) in order to identify energy efficiency enhancements opportunities.
Moreover, China has plans to transform the PRD a green living areas. Business opportunities exist in the areas of clean power generation, clean production, renewable energy, electrical vehicles, water conservation, and resource recycling.
