Nanoparticles Survive Waste Incineration & Contaminate Fly Ash

07 December 2012

A new study conducted on behalf of the European Commission’s Environment Directorate-General (DG) has shown that nanoparticles can pass through the waste incineration process into fly ash and slag and end up in landfill.

According to the study, the first to follow the fate of engineered nanoparticles through the entire waste incineration chain, the use of nanomaterials in consumer goods is growing, as is their presence in waste.

Engineered nanoparticles are often designed to be insoluble and stable when incorporated into consumer goods, so as not to be released during use, but according to the report this can cause problems if they enter the environment as they may reside for a long time.

The study focused on the nano form of cerium oxide (nano-CeO2), which has a wide range of uses, for example, in ceramics and as a glass polisher.

The researchers added nano-CeO2 particles to waste destined for a large-scale incinerator. The nanoparticles were introduced either directly onto the waste before incineration or into the gas stream exiting the furnace.

Samples were then taken from the flue gas and the residues of the combustion process, such as the fly ash, slag and slag water, and were then analysed for cerium content.

The results showed that the filter systems in the incinerator were highly effective, removing nearly 100% of the nano-CeO2. According to the researchers this suggests that no significant nano-CeO2 emissions can be expected from thermal waste to energy plants provided they have up-to-date flue gas cleaning systems.

The study said that the filters are effective because the nano-CeO2 binds loosely to the solid residues from the combustion process, which can then be efficiently removed using the filter technology.

However, the report also found that the nano-CeO2 is still present in the residues of fly ash and slag and, moreover, its chemical and physical properties have remained unchanged.

This suggests that the problem of disposal is shifted to the handling of slag and fly ash residues in landfills and final deposits.

The study cautioned that exposure to nanoparticles may occur during transportation or immediate storage, or if the slag or fly ash is treated for material recovery, for example, to recover copper, aluminium or zinc.

The research strongly recommends the use of the precautionary principle in developing measures to control nanoparticle waste and further exploring development of degradable nanoparticles.

Hong Kong considers mandatory glass recycling legislation

Minister weighs legislation that would mainly target wine and other drink bottles

The government is considering legislation to make glass recycling mandatory, the environment minister said yesterday.

Secretary for the Environment Wong Kam-sing said the legislation would target mainly wine and other beverage bottles.

He did not say who would be responsible for the recycling, but an environmental group said it would probably be importers or retailers.

Wong expected details of the legislation to be released in March, with new measures introduced by the end of the year. Glass accounts for 3 per cent of all waste in the city, and only 5 per cent of it is recycled, he said.

“We can’t say it’s insignificant,” he said. “We have to minimise waste in every aspect.”

Wong said he hoped legislation would result in much more of the city’s glass waste being recycled.

Edwin Lau Che-feng, director of Friends of the Earth, welcomed the idea.

He said the current strategy of funding non-government organisations’ glass recycling projects was unsustainable, and introducing laws would make it more systematic.

“Bottle producers will have to hire their own contractors or fund NGO projects to collect the bottles [under the proposed laws]. This way, it would be more sustainable,” he said.

“But I hope the legislation won’t be limited to glass bottles, but all beverage containers, such as cartons.”

As the city mainly imports wine, Lau expected wine importers, wholesalers or retailers would be responsible for bottle collection.

Yo Chau Fuk-yau, director of wine wholesaler Yee Sang International, said it would be “very difficult” for the company to take on collection of glass bottles. “The costs would be very high, and it should be pubs and retailers who are responsible.”

Hong Kong’s political parties need fuller disclosure of their funding

Submitted by admin on Jan 5th 2013, 12:00am

Comment›Insight & Opinion

SCMP Editorial

Political parties in Hong Kong are odd entities. Increasingly, they play an active role in governance, taking seats in the district councils, legislature, government advisory panels, the chief executive’s cabinet and ruling team. Given their strong influence on policies and public affairs, they are expected to adhere to the highest standard of transparency and accountability for their operations. But, oddly enough, most parties are only registered under the Companies Ordinance, which means their disclosure responsibilities are no more than for a private company. They are still, regrettably, reluctant to disclose sensitive information such as how they are financed. Public scrutiny is woefully limited.

Some light was shed in late 2011 when a leaked document suggested pro-democracy publisher Jimmy Lai Chee-ying had donated about HK$28 million to the Democratic Party and the Civic Party over the previous few years. Interestingly, a court case involving the control of Nina Wang Kung Yu-sum’s Chinachem Charitable Foundation also revealed that the Democrats had received donations from her. The court heard that the charity had given the party HK$4.2 million between 1997 and 1999. The revelation dispelled the belief that tycoons shun pro-democracy parties for fear of upsetting Beijing. Alas, the details only came to light in a lawsuit after 15 years.

It is speculation whether the late tycoon would have donated to the Democrats had she known that it would be disclosed. But understandably, prominent figures may not want to be seen as openly backing groups opposed by Beijing. The concern of pan-democrats that compulsory declaration of funding sources may deter donations appears to be valid.

But non-disclosure undermines public monitoring of elections. Although candidates have to cap their spending and list their donations, records show many just declare having received a lump sum from their party. Since sponsors can get around the rules via a party donation, the public is unable to tell who is truly bankrolling a candidate.

When political parties mushroomed in the ’90s, it was argued that too much regulation might restrict development. However, party politics has since come a long way. As universal suffrage draws nearer, parties are expected to play a more important role in governance. It makes sense to give them clear recognition. A party law can enhance transparency, accountability and credibility, allowing for better development.scmpost_17oct12_ns_lai_tw6941a-20121016160123830-_31952239.jpg

Hong Kong’s public consultations are ineffective

Submitted by admin on Jan 4th 2013, 12:00am

Comment›Letters

I refer to the letter from Garmen Chan Ka-yiu of the West Kowloon Cultural District Authority (“West Kowloon hotel was clear about its plans”, December 28).

Whether the authority was clear about such plans is debatable. I must take issue, however, with Mr Chan’s statement that the “proposed development plan underwent extensive public consultation”.

Having managed consultation and community engagement for dam and infrastructure projects in many countries across the globe, I would like to point out that the extent and quality of such “consultation” exercises in Hong Kong over the last 15 years has been risible.

None of the consultations conducted by Hong Kong’s public bodies or the civil contractors whom they employ would be acceptable in Namibia or Malawi, let alone advanced economies like Australia or Canada.

For a consultation to be effective, a number of factors must be satisfied. First, engagement must be early, that is, at the inception stage. Input must be obtained on the nature of the problem. Approaching the public for the first time with proposals that have already been put forward, as the arts hub authority has done, is too late.

Second, there should be a range of activities where individuals are able to define the content of the consultation, clarify issues, input hard data and build consensus. Much of the consultation conducted in Hong Kong – such as the single public meeting and phone-in line for the 75,000 Tung Chung residents to give feedback on the development of their town – fail totally, being limited, restrictive and unimaginative.

Third, there needs to be a demonstration that consultation was incorporated into the proponent’s decisions and that agreement was reached by consensus. Based on the political backlash against the current Hong Kong government, this has evidently not been done.

The consequence of a consultation that is both ineffective and insincere is development that fails to serve the needs of the majority. Whether the wholly inadequate exercises conducted in Hong Kong to date are due to incompetence, a paucity of skills and knowledge within the government, or, as the Hong Kong public suspects, collusion with big business, is a matter requiring further investigation.

What cannot be denied is that the development of this city has proceeded to serve the interests of the conglomerates, while the rest of society has become increasingly marginalised and disconnected. Is it any wonder there is a social and political crisis?

Outrage over ‘shark fin rooftop’

Agence France-Presse in Hong Kong

Hong Kong conservationists expressed outrage on Thursday after images of a factory rooftop covered in thousands of freshly sliced shark fins emerged, as they called for curbs on the “barbaric” trade.

The city is one of the world’s biggest markets for shark fins, which are used to make soup that is an expensive staple at Chinese banquets and viewed by many Asians as a rare delicacy.

Activist Gary Stokes who has visited the site estimated there are 15,000 to 20,000 fins being laid to dry on the rooftop on Hong Kong island ahead of an anticipated surge in demand over Lunar New Year in February this year.

“This is shocking,” the Hong Kong coordinator for conservation group Sea Shepherd told reporters, saying it was the first time that he has spotted such a massive hoarding of shark fins in one place in the city.

“This is the most graphic, brutal and barbaric part of the industry – the element of chopping a shark’s fin off and throwing it back into the water is horrific and inhumane,” he added.

Stokes believed the large amount of shark fins were destined for China, and that traders moved to dry the shark fins on secluded rooftops instead of sidewalks – as they have done in the past – to avoid public anger.

Campaigns against consuming shark fins have gained ground in Hong Kong in recent years, after major hotel chains decided to drop the soup from the menus, and Cathay Pacific said in September it would stop carrying unsustainable sourced shark products on its cargo flights.

“The demand in Hong Kong is definitely decreasing but unfortunately, the demand in China is growing,” Stokes said.

“As long as there is no protection for the sharks, the (demand) will just keep going on and on,” he added, urging Hong Kong authorities to ban the trade.

Environmentalists say the sustainable shark fin industry is tiny and most of the products are harvested in a way that threatens scores of shark species deemed vital for healthy oceans.

About 73 million sharks are killed every year, with Hong Kong importing about 10,000 tonnes annually for the past decade, according to environmental group WWF. Most of those fins are then exported to mainland China.

The number of threatened shark species has soared from 15 in 1996 to more than 180 in 2010, mainly due to the growing Chinese demand for fins.

Most cities expected to fail to meet stricter new air pollution standards

Stricter air quality measurements on mainland are seen as step forward in government transparency, but only five of 120 cities hit standard

Only five of 120 mainland cities logged “blue-sky days” on New Year’s Day as the first up-to-the-hour air quality readings were reported under tougher pollution standards.

Data posted on the Ministry of Environmental Protection’s website yesterday showed that most cities saw “moderate” levels of sulphur dioxide and PM10, or large particulate matter, with 29 cities showing slight pollution.

In Beijing, even the chilly winter winds failed to clear the smog, with most of its 35 monitoring stations showing “moderate” air pollution. The 24-hour reading of PM2.5 fine particulates in the southern area of Yizhuang stood at 153, or moderate pollution.

The outskirts of the city seemed to fare the worst. The remote Liulihe monitoring station in the southwestern suburbs of Fangshan district recorded the worst air quality index (AQI) in the city, 210. Several cities that are near the capital, such as Baoding, Shijiangzhuang and Tianjin, saw the worst pollution in the country.

The environmental ministry warned last year that at least two out of three of cities including Beijing, Shanghai and Guangzhou would fail to meet the revised air quality standards, which still lag behind World Health Organisation recommendations.

The new standards announced in March apply to ozone, carbon monoxide and PM2.5 – particles less than 2.5 microns in diameter that are linked to respiratory diseases – along with sulphur dioxide, nitrogen oxides and large particulate matter. Figures are reported hourly from 496 monitoring sites in 74 cities.

More than two dozen cities have begun updating daily PM2.5 readings in the past few months. Several, including Beijing and Guangzhou, are providing real-time PM2.5 data on a trial basis.

But Tuesday was the first time that the 74 biggest cities – mostly municipalities, provincial capitals and affluent commercial hubs in the Pearl and Yangtze river deltas – published hourly and daily pollution readings on government websites.

“It’s remarkable that the number of cities offering public access to real-time PM2.5 data has gone from zero to 74 in just over a year,” said Ma Jun , director of the Institute of Public and Environmental Affairs.

Heeding public concerns over the quality of the monitoring data, Wan Bentai , a chief engineer at the Ministry of Environmental Protection, said in a statement that authorities were focused on ensuring minimum interference from local governments during the release of pollution readings.

Environmental officials in Beijing said the adoption of the new standards would also mean the end of the mainland government’s tally of blue-sky days, which had been widely criticised as glossing over the truth about pollution.

Sanya , in Hainan , was among the five cities to get the rating yesterday.

“It is simply unacceptable that local authorities such as those in Beijing have said air pollution will not be brought under control until 2030 given the palpable human toll of smog problems,” Ma said.

“How difficult can it really be to control the sources of pollution and cut emissions?”

Policy address is key for CY to salvage waning popularity

Leung likely to announce populist measures %in an effort to revive his flagging popularity

The environment and education are two of the main issues to be raised by Chief Executive Leung Chun-ying in the policy address that he is writing under mounting political pressure following Tuesday’s protest marches.

The speech, which is scheduled to be delivered on January 16, is seen as the key to boosting Leung’s flagging popularity. But a former senior government adviser says he is not optimistic it will help the chief executive regain support and overcome a political stalemate.

Professor Lau Siu-kai, former head of the Central Policy Unit, said the turnout for the anti-government march on Tuesday, which was significantly higher than in previous new year marches, was a warning.

Lau said the rallies organised by the rival camps on Tuesday were evidence of heightened polarisation, which was also a matter of concern in Beijing.

According to a source familiar with the drafting of the policy address, it will contain populist measures, such as implementing 15 years of free education, including subsidies to kindergartens for teachers’ wages.

Roadside air quality will also be among the measures, in which billions of dollars will go to the Environment Bureau to subsidise the phasing out of older, higher polluting vehicles. Forming a land reserve for housing will also be included.

In the largest demonstration, organisers said more than 130,000 people marched to demand Leung’s resignation while police put the turnout at 26,000.

Lau was pessimistic about whether Leung could resolve the political stalemate he faced with a policy address. “If Leung puts forward drastic and ambitious measures, which incur long-term public spending, it would only spark bigger controversy.”

Xinhua reported that Zhang Xiaoming, director of the central government’s liaison office, had met Leung but did not say when. Released a day after the march, the report quoted Zhang as saying Leung’s policies had won wide recognition from society and that state leaders had affirmed his work.

A University of Hong Kong public opinion programme survey from December 18 to December 28 found Leung’s popularity rating scored 49.1 out of a possible 100 marks, down 0.1 from a poll between December 1-4.

Trash Incinerator “Part Of The Past”

The Minister for the Environment believes that the trash incinerator in Kirkjubæjarklaustur is a part of the past, and has recommended that it be shut down.

As reported, incinerators in the West Fjörds, the Westman Islands and in Kirkjubæjarklaustur have been shown to be emitting dioxin, a highly toxic chemical that was at one time used to make the notorious herbicide Agent Orange. The matter was first brought to light when dairy producers in the northwest detected unusually high amounts of dioxin in milk.

Traces of the toxin, albeit far below dangerous levels, were also found to be in some meat originating in south Iceland. The Ministry for the Environment called for an investigation into the matter, conducting inspections on all the facilities.

RÚV now reports that a committee assembled by the ministry has come to the conclusion that the incinerator in Kirkjubæjarklaustur is not up to code. Speaking to the press, Minister for the Environment Svandís Svavarsdóttir told reporters that “according to the conclusions of the ministry, this age of incinerators is over.”

However, the municipality of Kirkjubæjarklaustur has until January 11 to raise objections to the decision. Until that time, said the minister, she cannot give a more detailed statement than this on the matter.

A food recycling scheme uses discarded vegetables from a wet market to cook food for the unemployed

Banquet-loving Hong Kong grapples with mountain of food waste

By Katie Hunt Business reporter, BBC News, Hong Kong

Food stall in Hong Kong

It is dusk at Hong Kong’s Tai Wo wet market and the stallholders are shutting up shop, separating browning bean sprouts and bruised oranges from the fruit and vegetables fresh enough to be sold the next day.

Unlike the waste from most of the city’s fresh produce markets, which is dumped in one of three fast-filling landfills, the leftovers from this one are collected by a local food-recycling scheme.

Run by the Hong Kong Confederation of Trade Unions, it uses the discarded vegetables to cook meals for the unemployed. The rest is sent to local farms to be composted.

“We usually collect around 180kg, and around 70% is edible,” says Christina Jang, who works for the project in Tai Wo, near Hong Kong’s border with China.

“That can feed 60 people.”

Buffets and banquets

The metal carts are being pushed by a group of teenagers from a local secondary school.

Equipped with white-cloth gloves, they giggle and squirm as they fill blue plastic boxes with pineapple peelings, green beans and garlic shoots.

A city that loves its buffets and banquets, Hong Kong dumped 3,600 tonnes of food waste a day in 2011.

“We believe this process would be profitable, although it depends on the scale”

Carol Lin City University of Hong Kong

That is 11% more than in 2010 and the city looks particularly wasteful when compared to nearby countries.

According to figures provided by Friends of the Earth, Hong Kong generates half a kilo of food waste per head daily, compared with 0.36kg produced in Singapore, 0.35kg in Taiwan and 0.29kg in South Korea.

Friends of the Earth has launched a campaign encouraging people cut at least two dishes from the traditional banquets held to mark weddings, business deals and other special occasions. The elaborate meals can stretch to more than 12 courses.

Some two thirds of the city’s food waste comes from households, and a third from the city’s supermarkets, food stores, restaurants, hotels and schools. But it is food waste from this latter group that is expanding quickest.

Recycling options are few and far between. Most people live in high-rise apartments, with no space for composting and, as yet, there is no city-wide formal recycling for food waste.

The issue has taken on greater urgency as the city’s three landfill sites reach bursting point. All three are expected to be full by 2018.

Food waste per capita (kg/day) 0.50 0.36 0.35
Population 7,103,700 5,180,000 23,194,000

Novel approaches

In this gap, charities, business and scientists are coming up with their own solutions to the city’s food waste problem.

Two dozen non-governmental organisations and charities are said to operate food recycling programmes similar to the one at the Tai Wo wet market.

Biotechnology is another alternative, says Carol Lin, a scientist at City University of Hong Kong.

She has pioneered a technique that takes bakery and other food waste and makes succinic acid, a chemical that is widely used in the production of plastics, fabric and other fibres.

“We believe this process would be profitable, although it depends on the scale,” she says.

Succinic acid is normally made from petrochemicals, so her bio-refinery offers a potential double benefit – a commercial use of food waste and a way to reduce reliance on finite resources such as oil.

So far, though, no company has been willing to make the 19m Hong Kong dollar ($2.5m; £1.5m) investment needed to build a plant in Hong Kong, where land is scarce and expensive.

Pay as you throw

The government has begun to consider a city-wide solution to mounting levels of leftover food. Recently, it pledged to cut food waste by 10% in three years.

It has also launched a public consultation on charging for waste collection – a strategy that has led to a significant fall in waste disposal in Seoul and Taiwan.Students carrying baskets of discarded vegetables

Hong Kong is trying to raise awareness of food wastage among students

A per-bag charging scheme introduced in Taipei in 2000 reduced domestic waste disposal by 62% and domestic waste generation by 20% over a 10-year period, according to the consultation document.

Taipei also closed refuse collection points and public litter bins to avoid illegal dumping and the scheme’s success allowed the country to delay the construction of rubbish incinerators.

It remains to be seen whether famously free-market Hong Kong will be prepared to adopt such charges.

However, a poll conducted by Friends of the Earth in November suggested that 65% of 1,000 people surveyed would be willing to pay a fee, up from 52% six months earlier.

Memorable meal

Back at the wet market, the students wheel their carts of unsold vegetables to a kitchen used by the union’s training centre.

Two cooks sift and weigh the salvaged vegetables and whip up a selection of dishes – papaya soup, tomatoes and eggs, stir-fried cauliflower and cabbage.

They are wolfed down by the hungry teenagers, who declared they would never have guessed their meal was made from discarded food.

Their teacher, Alice Lee, hopes the experience will encourage the students to think twice about the food they waste – many of them throw away their school lunches and eat instant noodles from the tuck shop instead, she says.

The project organisers hope it is a meal that will stick in the students’ minds and, ultimately, help take a bite out of the city’s food waste mountain.
