A group of academics and professionals has now melded their minds with the stubborn ones of Hong Kong officials, pushing for the building of an incinerator for the treatment of the city’s waste.
Representative statements include “We need to act now, or this will end with rubbish piling up on the streets,” from Professor Poon Chi-sun of Polytechnic University’s civil and environmental engineering department, and “Decision makers need to find the most sensible choice – can we take the risk of having so much uncertainty when we have thousands of tonnes of rubbish to handle?” from Professor Irene Lo Man-chi, of the University of Science and Technology’s department of civil and environmental engineering.
The most sensible thing to do, of course, is to first retain composure, lest such voices of panic pressures Hong Kong into making a disastrous decision just for the sake of having to ‘act now’.
A look at their statements reveal aspects meant to mislead and hoodwink audiences. Poon, for example, says, “We have strong reservations about the proposal to double the size of the Tuen Mun landfill, especially when incineration could effectively reduce the volume of waste by up to 90 per cent.” Retailers also attract customers by offering discounts “up to 90 per cent”, when most of the discounts never come close. In the case of incineration, 30% of incinerated waste ends up as toxic fly ash – requiring more landfills and leaving even deadlier pollution than conventional landfilling of waste.
In discussing plasma technology, Lo is reported to have said that problems with plasma technology had led to the closure of a 10-year-old plant in Japan, which had been down for two-thirds of that time. These problems are, in fact, not technical, but a matter of business dealings – in a country with thousands of incinerators, the plasma plant had to close “due to lack of feedstock (loss of long term feed contracts).” Incinerators are both waste treatment and business, and they require feedstock and fuels to remain operational; it is not surprising that the plasma plant couldn’t compete with an established industry over feedstock supplies. Lo’s statement, however, makes it easy to mislead readers over the exact nature of the cited case.
Lo also said the technology had been proved to be a reliable option that was safe in terms of emissions, syncing her opinion with the ‘proven technology’ refrain of Hong Kong officials. ‘Reliable’ is a very attractive word for the public, but it is unclear what exactly is meant when incineration is ‘reliable’. Having the ability to reduce the mass and increase the toxicity of the materials going to landfills does not seem to fit the idea of ‘reliable’. Incinerator accidents in Guangzhou and Shanghai shows that incinerators are not necessarily accident-free ‘reliable’; U.S. regulatory agencies have also found that incinerators are prone to various types of malfunctions, system failures and breakdowns, which routinely lead to serious air pollution control problems and increased emissions that are dangerous to public health. What is ‘reliable’ about incineration is its ‘reliable’ business opportunity for the operator and its beneficiaries, and its ‘reliable’ demand for feedstocks and fuel, which actively discourages recycling efforts and increases consumption of fossil fuel.
Likewise, ‘safe’ also makes for attractive reading, but ‘safe emissions’ has no real meaning other than to indicate a high level of control over the emissions of pollutants. Emissions that are captured are actually re-released into the environment as ash or sludge after treatment, in even higher concentration of toxicity. Meanwhile, ultra-fine toxic particles such as dioxins can still escape emissions control and seriously endanger human health.
The stubborn attitude displayed by Hong Kong officials over incineration has always been frustrating, but it is especially worrying that academics and professionals – people walking around with an air of credibility – is choosing to join in and support a move that will endanger the future of Hong Kong’s waste management, environment, and the health of its citizens. It is imperative, therefore, that Hong Kong citizens recognize the panic pressure that they are trying to generate, and the shrewd sales language that they use in trying to cajole the public into accepting incineration.
The issue was reported by Cheung Chi-fai of the SCMP.
