Tuen Mun Incinerator Plan PDF Print E-mail

Tuen Mun District Council Member Terry LI Kwai Fong has alerted goldcoastonline.hk to the Legislative Council plan to build a 'sludge' incinerator in Tuen Mun to burn sewage waste.

Legco has already made an appropriation of HK$ 5.15 billion to the Environment Bureau for building an incinerator in Tsang Tsui, Tuen Mun. On top of capital costs, the incinerator - which will reduce sludge by 90 percent - will need HK$145 million a year in maintenance. The Environmental Protection Department said continuing to bury at landfills could lead to slope failures and dangerous sludge-slides. The government said the incinerator will be commissioned by 2012 and handle 2,000 tonnes of sludge a day by 2016. It will also create 613 construction jobs and 60 permanent jobs, according to a Legislative Council paper.

Legco has identified an ash lagoon at Tsang Tsui near Nim Wan in Tuen Mun as a prospective site.

So Hong Kong needs to deal with 2 thousand tonnes of sludge and 20 thousand tonnes of waste every day - all well and good if the sludge needs to be disposed of...


"If the incinerator is working continually for 24 hours, the heat of the emitted fumes will cause a rise of 1 to 2 degree Celsius in the whole Tuen Mun district. In addition, the United Nations Convention also points out that incinerators are the main source of the production of dioxin which is carcinogenic. As far as we are concerned, the number of new cases of cancer is continually rising with an average of 2500 new cases per year within which the lung cancer rank the first place.  Incineration not only causes a rise in temperature which leads to the acceleration of global warming, but also affects the health of citizens.

Apart from the deteriorating problem of global warming, the toxic fumes emitted are our main concern. The government departments which support the construction of incinerator believe that incineration is the only solution to the problem as the landfills are going to be full soon. However, the side effects of this method outweigh the benefits of it. Incineration releases harmful substances such as sulphur dioxide (SO2), nitrogen oxides (NOx), heavy metals, Zinc and respirable suspended particulates which will destroy our breathing systems and cause cancer, sterility as well as genetic problems. As a result, incineration is not the cure and cannot be the long term solution as the hazardous pollutants not only affect us but also our next generation.

Despite the fact that the concentration of dioxin is within the “acceptable” level for human exposure from the health risk assessment report of the Environmental Protection Department, the actual concentration of dioxin emission is affected by the temperature of incineration and whether the waste is separated from plastic bags and bottles. Therefore, we urge the government to reflect the current waste disposal methods and take an initiative to enforce the programme on Source Separation of Domestic Waste.
To one’s surprise, Hong Kong as a cosmopolitan city is going to construct an incinerator to deal with the sewage from Hong Kong’s Victoria Harbour in order to improve the water quality known as Harbour Area Treatment Scheme and the sludge from the sewage treatment plants. The emission of toxic pollutants from incineration causes air pollution. Since the incinerator is required to work for 24 hours, the consumption of electricity must increase which in turn leads to the rise of carbon emission.

The construction of incinerator is contradictory to the campaigns promoted by the Hong Kong government to protect the environment and public health. Taiwan and Singapore have already tested the most advanced “room condition sludge dewatering technology*”.  This alternative is environmentally friendly which treats the sludge in room temperature and no incineration is required. Our group has invited the Environment Bureau to come and visit the new technology.  However, we have been turned down without reason. This issue is concerned with the public interests of environment and health risk but the government continues to turn a deaf ear to our opinions and insists on following the idea of sludge treatment proposed in 2005. For the sake of the safety of 7 million citizens, all of us should voice our opinions and express our concerns so as to urge the government to face the problem and abandon the incinerator project.

*HC Eco Technology announce the latest breakthrough advance in sludge processing technology

Press Release                               
15 July 2010

The World 1st Efficient Sludge Dewatering Technology
A new sustainable solution for sludge processing

HC Eco Technology Pte Limited, a Singapore based green technology company, officially announce a new sludge processing technology.

With 8 years R&D on various types of sludge, HC Eco Technology has developed the world 1st super efficient sludge dewatering technology achieving a dewatering ratio never achieved before! 

A real breakthrough of physio-chemical mechanisms and kinetic principles, the technology reduces the water content from around 98% to around 45% or further to below 10% under room condition (Non Thermal). This advancement in technology has fast become a vital component for sludge treatment which is low cost, low energy consuming, achieving 100% reused on sludge and zero emission.

Sludge is the fluid residue from sewage treatment and industrial process comprising mainly organic substances, with relatively low density, small solid particles and high water content but is difficult to dewater. Presently, the dewatered sludge from sewage treatment plants is still very high (around 80%) in water content and unstable, which is not suitable for immediate use or disposal. If sludge is discharged or disposed improperly, it will cause serious pollution to the environment.

This new technology is the ultimate sustainable solution to replace existing high cost high energy consuming technologies, incineration for example, as one of the major sustainable technology to save our Earth.
