Fighting for rubbish

High value of unwanted goods spark karung guni turf wars and a punch-up in Tampines
Hedy Khoo, The New Paper 24 Aug 08;

SOME people cannot wait to get rid of their used stuff, and then there are some who fight over the junk.

This was what happened when a dispute arose between rival camps in the rag-and-bone business, better known here as karung guni men.

Mr Heng Kim Suan, 37, suffered a cut and swollen jaw after he was allegedly punched by a foreign worker who was also hunting for throwaway treasure last week at Block 883, Tampines Street 84.

Mr Heng, a karung guni man of three years, recalled that he had just finished picking up used goods around the block last Wednesday afternoon and was pushing his trolley towards his pick-up.

That was when he saw a China national approach him with an empty trolley. He claimed that the man then rushed up suddenly and rammed his trolley against his.

'He shouted at me in Mandarin that he could also collect things at the same block,' Mr Heng said.

'But before I could react, he swung a punch at me. I only realised my upper lip had been cut when I put my hand to my face and it was covered with blood.'

He said the man then ran off.

Too dizzy to chase

'I tried to chase him, but I couldn't because I felt too dizzy,' Mr Heng said.

He made a phone call to the police and an ambulance took him to the hospital for treatment.

Mr Heng said: 'The medical fee was $75, but I was given two days' medical leave. Not working means I lost two days of income.'

He also lodged a police report on the same day.

The resale value of old newspapers, plastic bottles and other used items such as electrical appliances, has become so lucrative that territorial disputes are now getting common.

Mr Wong Kin Yong, 47, who has been a karung guni man for seven years, said in Mandarin: 'We have had frequent disputes with the new karung guni men over collecting in the same area, but this is the first time someone has been hit.

'You don't need a licence to be a karung guni man, but those in the trade know the unwritten rules.

'We all work on an understanding that if you drive into a carpark and you see a fellow karung guni man's lorry parked below a block, you move on.'

He said many foreign workers had joined the trade in the past five years.

He complained: 'The problem is that the newcomers don't respect the unwritten rules. They don't care if they see another karung guni man's lorry, they still insist on collecting from there too.'

Another karung guni man, who wanted to be known only as Ronnie, said: 'Five years ago, we can earn up to $300 on a good day.

Tough competition

'The minimum is at least $100 a day. But in recent years, so many people have joined the trade that to even get $60 a day is difficult.'

Ronnie, 52, said that about 20 local karung guni men collect in the Tampines area.

'We have been here for years and we know each other. We follow the rules when it comes to collection.

'There is no demarcated territory. It is, simply, whoever gets there first is entitled to collect the used goods there,' he explained.

In the face of competition, some karung guni men have found more enterprising ways to make money.

Ronnie said: 'Some karung guni men got tired of the physical labour and they now work with foreign workers. They take about seven to 20 workers, depending on the size of their lorries.'

The karung guni men will then buy whatever used goods the workers manage to collect.

'That way, they don't need to do the manual labour themselves and their profit is higher,' he said.

'If the collection is good, these karung guni man can actually make more than $1,000 a day, if he takes 10 workersaround.'

He also said that in the past, karung guni men in the Tampines area had agreed to start collecting only from 10.30am.

'This is so we do not disturb the residents with our horns and shouts too early in the morning,' he explained.

Break rules

'But the newcomers don't care. They start at 9.30am and we lose out.'

Mr Heng said: 'It's really not worth it that I got punched over used goods.'

'We may not earn as much as we used to, but if everyone respects one another and show some courtesy, there is still money to be made.

'Every day, people will still have things to discard. Rubbish will not run out.'

Couple struck by lightning at Punggol jetty

Gracia Chiang, Straits Times 24 Aug 08;

A couple fishing in the open at Punggol jetty were hit by lightning yesterday afternoon.

The Singapore Civil Defence Force (SCDF) received a call at 1.45pm about the incident.

Two ambulances arrived in about 10 minutes.

Paramedics said the 61-year-old Chinese man was not breathing and there was no pulse. There were also burn marks on his chest.

'I just kept screaming for help and for someone to call the ambulance,' said his 54-year-old wife, who declined to be named.

The couple had been fishing for two hours when it started to drizzle. As it was not a heavy downpour, the couple decided to stay on.

'My husband was just saying that it's okay, there's no thunder today. Shortly after he said that, the lightning struck and he collapsed,' she said in Mandarin.

She added that had they gone to their usual fishing spot at the East Coast - where there is shelter - they might have averted danger.

They had chosen Punggol because it is nearer their home in Sengkang.

She said others who were fishing nearby had also felt an electric current but were uninjured.

When asked what else happened after her husband fell to the ground, she said: 'It all happened so fast. I can't remember. I was not very conscious.'

She escaped with numbness in her right foot and redness on her left arm.

The couple were sent to Changi General Hospital's Accident and Emergency Department.

The Sunday Times understands that the man's condition is critical and he is in intensive care while his wife has been transferred to a general ward.

The National Environment Agency has said that Singapore has one of the highest rates of lightning activity in the world.

Conditions here are favourable for the development of lightning-producing thunderstorm clouds and an average of 171 thunderstorm days are recorded annually.

Couple hospitalised after being struck by lightning
By Lynda Hong, Channel NewsAsia 23 Aug 08;

SINGAPORE: Lightning struck a couple at Punggol Jetty on Saturday afternoon.

The 51-year-old man was found with slight burns on his chest. He was not breathing and paramedics had to administer CPR throughout the trip to the Changi General Hospital, where he is currently being treated.

His 54-year-old wife suffered redness on her arms as well as slight numbness on her right foot. She was also admitted to Changi General Hospital.

The National Environment Agency (NEA) says Singapore, which lies near the Equator, has one of the world's highest rates of lightning activity.

This is because hot and humid weather throughout the year makes it easy for lightning-producing thunderstorm clouds to develop.

The NEA advises the public against using electronic equipment and holding metal objects like an umbrella when there is an approaching thunderstorm.

Climate change is real, compelling and urgent

Björn Lomborg has been a persistent global warming naysayer and his claims misrepresent my findings
Gary Yohe, guardian.co.uk 22 Aug 08;

In late 2009, the world's top climate scientists, environmental officials and business and NGO leaders will converge on Copenhagen to negotiate a solution to climate change. It will be a meeting with global repercussions, and its participants will be united by a common belief in the need for a comprehensive solution to this common threat.

The need for such a solution is supported by the best science available, including the report of the Intergovernmental Panel on Climate Change (IPCC), which was awarded the Nobel peace prize in 2007 and of which I was a member. The IPCC's message is clear: climate change is real, compelling and urgent - and we need a concerted, comprehensive and immediate effort to confront it.

But in the midst of this momentum and clarity, one voice has stood out as a persistent naysayer.

Bjorn Lomborg, author of The Sceptical Environmentalist, makes headlines around the world by arguing that capping carbon dioxide emissions is a waste of resources. He recently published a piece in the Guardian in which he dismissed efforts to craft a global carbon cap as "constant outbidding by frantic campaigners" to "get the public to accept their civilisation-changing proposals".

To support his argument, Lomborg often cites the Copenhagen Consensus project, a 2008 effort intended to inform climate negotiators. But there's just one problem: as one of the authors of the Copenhagen Consensus Project's principal climate paper, I can say with certainty that Lomborg is misrepresenting our findings thanks to a highly selective memory.

Lomborg claims that our "bottom line is that benefits from global warming right now outweigh the costs" and that "[g]lobal warming will continue to be a net benefit until about 2070." This is a deliberate distortion of our conclusions.

We did find that climate change will result in some benefits for developed countries, but only for modest climate change (up to global temperature increases of 2C - not the 4 degrees that Lomborg is discussing in his piece). But developed countries are relatively prepared to handle climate change's effects - they tend to be in colder areas, and they have the infrastructure to mitigate severe depletion of resources like fresh water and arable land.

That is precisely why our analysis concluded - and Lomborg ignores - that climate change will cause immediate losses for developing countries and the planet's most vulnerable, millions of whom are already facing challenges that climate change will exacerbate.

Downplaying the threat of climate change allows Lomborg to focus on his claim that "unlike even moderate CO2 cuts, which cost more than they do good, we should focus on investing in finding cheaper low-carbon energy." He attributes this finding to our analysis as well, but again he overlooks a key element of our work.

Of course the world needs to make significant investments in cheaper, low-carbon energy. But making those investments without also implementing a constraint on emissions would fail to address the problem.

Our analysis assumed that over the next century, $800bn will be spent confronting climate change - $50bn spent on R&D in the next 5-10 years, and the remaining $750bn spent on adaptation and mitigation. This allocation of resources will reduce the cost of "clean" technology and increase the effectiveness of policies - like capping emissions - that are designed to reduce global CO2.

In short, we never advocated research into new technologies as a stand-alone way to fight climate change, nor did we accept Lomborg's dismissive attitude toward the threat climate change poses.

The negotiators in Copenhagen will need credible, accurately reported analyses upon which to base their discussions. This is not the time to deny the scope of the problem or belittle efforts to implement solutions. We need all options on the table. This was the message of the Copenhagen Consensus Challenge paper, and even a sceptical environmentalist should understand that.

Canada creates new wildlife areas in far north

Reuters 22 Aug 08;

TORONTO (Reuters) - The Canadian government and a number of Inuit groups unveiled a pact on Friday that will shelter the habitat of polar bears, bowhead whales and other animals in the country's northern Nunavut territory.

Canada will spend C$8.3 million ($7.9 million) on the agreement, which will create three new national wildlife areas on and around Baffin Island, Canada's largest island.

The deal will also lead to co-management between the government and Inuit native groups of two existing wildlife areas and eight existing migratory bird sanctuaries across Nunavut, a territory the size of Western Europe.

"We're putting our money where our mouth is in today's action for the environment," Environment Minister John Baird told reporters in Ottawa.

Baird said the agreement will also help protect seals, walruses and various migratory bird species.

Russian government gives Far Eastern Leopard chance for survival

WWF website 21 Aug 08;

The survival of the 35 remaining Amur leopards of the Russian Far East has been given a huge boost following a government decision to establish a unified, centrally governed protected area.

The proposal will see jurisdiction of Russia’s oldest nature reserve, Kedrovaya Pad, as well as two adjacent wildlife refuges transferred to the Ministry of Natural Resources and Ecology from the three separate agencies that currently regulate them.

“Decentralised management of the protected areas in the leopard habitat made it impossible to implement a unified program for leopard restoration over many years,” said Igor Chestin, Director of WWF Russia. “Moreover, protection of Red List species, which includes the Far Eastern Leopards, did not fall under the remit of any of the other agencies.”

Russian Vice-Premier Sergei Ivanov served as arbiter in meetings between the agencies, and his support for the proposal was key to enabling all parties to come to an agreement.

“This announcement marks the culmination of five years of hard work by WWF” added Chestin “This is a real opportunity for the leopard population in the region to gain a foothold and pull themselves up from the brink of extinction."

Once established, the joint protected area will cover about 2,000 square kilometres, and will be home to half of the remaining leopard population.

Discussions at the meeting also turned to other threats to the leopard population, including poaching and construction projects through the protected area.

“Any construction in the region should take into consideration the fragile state of this leopard population,” said Chestin. “Activities undertaken should in no way threaten the existence of the species.”

The agreement also includes a mandate for the Russian Ministry of Foreign Affairs to start formal talks with the Chinese Government on an agreement for transboundary conservation of the Far Eastern leopard.

Ivory poachers decimate Congo elephant population

Joe Bavier, Reuters 22 Aug 08;

KINSHASA (Reuters) - Poachers in Congo have killed a fifth of the elephants in Africa's oldest national park this year as China buys more ivory, the park's director said on Friday.

Rwandan rebels have killed seven Savannah elephants in the past 10 days alone in the Virunga National Park, along Congo's eastern border with Rwanda and Uganda, Emmanuel de Merode told Reuters.

"We've definitely lost 20 percent of the population this year and probably more," he said. "We have rangers with them, and we're trying to reinforce them. But (the rangers) are outnumbered 20 to one."

The 790,000-hectare (2 million-acre) reserve was home to one of central Africa's largest Savannah elephant herds in the 1970s numbering around 5,000.

But a brutal 1998-2003 war, heavy poaching, corruption and mismanagement of the park have taken a heavy toll. Today conservationists believe no more than 300 elephants remain.

China, among the world's main destinations for illegal ivory, was granted permission last month to buy 108 tonnes of ivory stocks from Botswana, Namibia, South Africa and Zimbabwe by the Convention on International Trade in Endangered Species.

De Merode singled out China's growing appetite for ivory as one of the root causes of this year's increase in elephant killings, as poachers attempt to launder their illegal ivory for legitimate sale.

"It's very difficult to distinguish between legal and illegal stocks," he said.

Despite the official end of the conflict in Congo, the eastern borderlands remain a volatile patchwork of rebel strongholds and militia controlled zones.

Armed clashes between rival armed groups are a regular occurrence, limiting the rangers' ability to patrol, and providing cover for poaching.

The Savannah elephant is a sub-species of the African elephant, which is classified as a vulnerable species by the International Union for Conservation of Nature and Natural Resources.

Elephants Decimated in Congo Park; China Demand Blamed
Zoe Alsop, National Geographic News 29 Aug 08;

Since the beginning of this year, armed groups, soldiers, and poachers have killed 10 percent of the elephants in Congo's troubled Virunga National Park—allegedly driven by rising Chinese demand for ivory—park officials say.

The announcement raises fears that elephants could disappear forever from Africa's oldest and largest national park, which has recently made headlines for its gorilla murders.

Rangers plying the lawless central sector of Virunga have discovered the bodies of seven elephants in the past two weeks alone.

In one case they came upon Rwandan militia members hovering over the bodies of two elephants. The rangers managed to drive the men away before they could remove the animals' tusks.

In all, 24 elephants are known to have been killed in Virunga so far this year.

"We believe that less than ten were killed last year," said Samantha Newport, spokesperson for Virunga National Park. "Undoubtedly this year is a lot, lot worse. It's catastrophic."

Chinese to Blame?

The Democratic Republic of Congo (DRC) is one of the primary sources of illegally trafficked ivory in the world, according to TRAFFIC, a group that monitors the wildlife trade.

Recently, the tiny elephant population of Virunga in the conflict-riven east of the country has become the target of gunmen hoping to unload the illegal ivory into a thriving international black market, park officials say.

Virunga's elephant population is small—thought to number between 200 and 300 animals—and isolated. It will not be able to sustain itself if killings continue at this rate, said Noelle Kumpel, program manager at the Zoological Society of London, which is working to support the rehabilitation and management of Virunga.

There's been a surge in the volume of illegal ivory since 2004, said Tom Milliken, regional director of TRAFFIC for eastern and southern Africa. Experts attribute the trend to thriving and overt domestic markets in the contraband throughout central Africa, in combination with a newly tapped appetite for ivory among China's rising middle class.

"We are hemorrhaging elephants out of central Africa and the Congo Basin," Milliken said.

One study Milliken worked on estimated that unregulated ivory-carving industries in Africa and Asia could be handling as much as 83 tons of ivory every year, most of it from central Africa. That could be the equivalent of around 12,000 elephants, he added.

Tiny Population in the Crossfire

Virunga sits at the heart of one of the most deadly conflict zones on the planet, with at least four heavily armed and rarely paid factions fighting for control of the park.

"It's incredibly challenging for the rangers to do their job on the ground when, at every turn, they are confronted by an armed group that is obviously more powerful than they are," Virunga National Park's Newport said.

"Over the last ten years about 120 rangers have been killed doing their jobs. It's an African miracle that Virunga National Park still exists—and a credit to the rangers."

Surveys carried out in the 1960s found 2,889 elephants in the park. By 2006 that number had dropped to 400. Just two years later it's estimated there are as few as half that number.

For those protecting the park, elephant numbers are a litmus test for survivability of the park itself.

"Elephants are an indicator species," Newport said. "And now to have the elephants killed off—it's a black mark against conservation in Virunga."

Noelle Kumpel, Virunga program director at the Zoological Society of London, said, "The loss of the elephants will have very dramatic impact on the park.

"They act as ecosystem engineers by removing trees and thus opening up savannas. And in the forests trees rely on them for seed dispersal and other species rely those trees, and so it will have a knock-on effect."

Refuge … For Militias

Virunga's animal populations have survived over a decade of civil wars that have left more than five million people dead and have displaced hundreds of thousands more in eastern DRC.

"For militias, Virunga National Park is a refuge," park spokesperson Newport said. "It's a place to rest, to eat, to sleep, to train."

Many members of the warring factions moonlight as poachers, surviving off bush meat and, in at least one case documented by the BBC, trading ivory for ammunitions.

Black Market and Controversial Legal Trade

Trade in illicit ivory is on the rise, conservation groups say.

The Elephant Trade Information System, an ivory-monitoring body, reported that the volume of illegal ivory confiscated in 2006 was more than twice what had been discovered two years earlier.

And last month the Convention on International Trade in Endangered Species (CITES) certified China to pursue a one-time purchase of ivory, granting the country permission to bid on 108 tons of stockpiled ivory from four southern African countries: Botswana, Namibia, South Africa, and Zimbabwe. Japan has also been authorized to buy government-held ivory from those countries.

Some conservationists argue that the legal sale of ivory—even when the proceeds go toward conservation, as they must under current CITES regulations—destroys the taboo around buying ivory, which encourages demand.

On the ground in Virunga, that may mean poachers are more confident they'll find a market for their spoils.

"The perception on the ground from poachers and armed militias is that it's OK, because China wants the ivory and is allowed to have the ivory," Newport said.

But, TRAFFIC's Milliken said, "The market is already there—there's nothing to create."

And, he said, "by allowing China to participate in a legal ivory trade, it could undermine black market products."

Still, the ivory trade begins at the local level, where it often goes unprosecuted—a fact easily exploited by foreigners looking to ship it overseas.

"DRC has to do more if you can buy and sell ivory with no impediments within walking distance of the police headquarters in Kinshasa," Milliken said.

Real-World Recycling Puts U.S. to Shame

Meredith F. Small, LiveScience.com 23 Aug 08;

The other day I was walking through a store that specializes in ethnic goods from around the world, and I picked up a magnificent serving tray from Zimbabwe. It was about two feet across, a spiral of tightly woven white material marked with bright spots of blue and orange.

"What's this made of?" I asked the clerk, expecting him to name some exotic reeds, or maybe branches from a tree found only on the African savanna. "Plastic bags" was his answer, and even looking close, you couldn't tell.

But once I knew, I could imagine the artist gathering up all those plastic bags that now dot the roadsides of Africa and devising a way to make something useful, and beautiful, out of someone else's trash.

In Western culture, we think recycling is all about putting your newspapers and bottles in the right bins, and maybe using recycled paper in the printer or Xerox machine. But in other countries, ones that are not so awash in material goods, anything and everything has a second, third and maybe a fourth life.

In Bali, Indonesia, for example, a coke bottle is not just returned for deposit. Instead, all soda bottles are washed by hand at home and then refilled with all kinds of drinks from water to tea. These bottles also come in handy to transport gasoline to a stalled moped.

In most other countries, used car tires don't just stack up. They are cut into pieces and crafted into flip flops, becoming sandals with "all weather" tread.

In East Africa, people also make good use out of discarded tins. I've seen bright yellow Penzoil cans cut and reformed into votive lamps and palm oil cans flattened and used for roofing material.

Kids also take meat tins and beer cans and fashion them into various toys such as cars and boats. Along the roadside and in tourist camps, these kids scrounging for materials and with a little time and workmanship morph them into something just as good - and often more interesting - than a toy from a box.

But my favorite type of recycled good is the object of beauty.

I own a pair of Maasai earrings that I bought from a woman in Tanzania. They are flaps of leather eight inches long and two inches wide. The leather is covered with an intricate design of red, blue, and orange glass beads and set with several white shirt buttons. Hanging off the sides are arrowheads made of hammered metal from a can that probably held tuna, or peaches, or spam.

And only after hours of staring at these objects of incredible craftsmanship one day did I suddenly realize that the outline of each earring is made by one half of a zipper, presumably torn from a old pair of trousers left by the road by someone who apparently had no idea of their artistic value.

Although they are as beautiful as a pair of the finest Tiffany earrings, I only have the usual Western pin-sized pierced earring holes and my lobes simply can't accommodate two-inch wide flaps of leather.
And so this pair of earrings made of recycled goods hangs on my wall as a piece of fine art.

Flat-screen TV gases may be added to climate fight

Alister Doyle, Reuters 22 Aug 08;

ACCRA (Reuters) - New greenhouse gases emitted in making flat-screen televisions or some refrigerants might be capped under a planned U.N. treaty to combat global warming, delegates at U.N. talks in Ghana said on Friday.

Emissions of the recently developed industrial gases, including nitrogen trifluoride and fluorinated ethers, are estimated at just 0.3 percent of emissions of conventional greenhouse gases by rich nations. But the emissions are surging.

"I think it's a good idea" to add new gases to a group of six already capped by the U.N.'s Kyoto Protocol for slowing global warming, Yvo de Boer, head of the U.N. Climate Change Secretariat, told Reuters.

"It makes sense to address all gases that lead to climate change," he said on the sidelines of the August 21-27 talks in Ghana meant to help work out details of a new treaty to combat global warming due to be agreed at the end of 2009.

"The more gases you cover, the greater flexibility countries have" to work out how best to cut back, he said. He added that it was up to governments to decide.

More than 190 nations have agreed to work out a broad new pact to succeed Kyoto as part of a drive to avert rising temperatures likely to bring more heatwaves, floods, desertification and rising seas.

De Boer said the European Union had originally, in negotiations more than a decade ago that led to Kyoto, favored limiting the treaty to carbon dioxide, emitted by burning fossil fuels in factories, power plants and cars.

LIVESTOCK

But the addition of five other gases, such as industrial nitrous oxide or methane, emitted by livestock or rotting vegetation in landfills, had bolstered Kyoto, he said. Carbon dioxide is the main gas, accounting for 80 percent of emissions.

Among new gases, nitrogen trifluoride is used in making semiconductors such as in flat-screen televisions. Fluorinated ethers have been used in some refrigerants in recent years as replacements for another group of gases found to damage the earth's protective ozone layer.

Other new gases, such as iodotrifluoromethane or methyl chloroform, are used in the electronics industry or occur as by-products of industry.

"Very little is known about sources, current and future emissions and atmospheric abundance of these gases," according to a technical report presented to delegates.

"Emissions in 1990 are assumed to have been close to zero but are increasing exponentially," it said.

It estimated that current annual emissions were below the equivalent of 50 million tonnes of carbon dioxide -- or 0.3 percent of greenhouse gas emissions from human activities in rich nations.

For carbon markets, the impact of adding new gases was unknown but would "in principle, increase the demand for tradable units under the Kyoto Protocol," it said.

Disadvantages were that it could cost a lot to set up new monitoring and could distract focus from more important gases.

"I'm pushing this issue to get more clarity," said Harald Dovland, a Norwegian official who chairs a group in Accra looking into new commitments by backers of Kyoto.

Kyoto obliges 37 rich nations to cut emissions by 5 percent below 1990 levels by 2008-12. "There are not big amounts of these new gases emitted now. But many parties want to ensure that there are no increases," he said.

Nuclear waste containers likely to fail, warns 'devastating' UK report

Environment Agency reveals thousands of holders do not meet basic specifications for storage and disposal
Geoffrey Lean, The Independent 24 Aug 08;

Thousands of containers of lethal nuclear waste are likely to fail before being safely sealed away underground, a devastating official report concludes.

The unpublicised report is by the Environment Agency, which has to approve any proposals for getting rid of the waste that remains deadly for tens of thousands of years.

The document effectively destroys Britain's already shaky disposal plans just as ministers are preparing an expansion of nuclear power.

It shows that many containers used to store the waste are made of second-rate materials, are handled carelessly, and are liable to corrode.

The report concludes: "It is cautious to assume a significant proportion will fail." It says computer models suggest up to 40 per cent of them could be at risk.

Britain's leading expert on nuclear waste yesterday called the report "devastating" and Peter Ainsworth, the Conservative environment spokesman, said he would write to ministers to urge them to "make changes to ensure public safety". He added: "Such a warning from the Environment Agency must be taken extremely seriously. The failure of just one container could prove catastrophic."

The report says that "tens of thousands" of containers of immensely dangerous waste, bound in concrete, are simply being stored above ground, mainly at Sellafield, while the Government and the nuclear industry decide what to do with them. On present plans it is assumed they will remain there for up to another 150 years before being placed in a repository underground. It will take another 50 years to fill the repository, which will then remain open for another 300 years, while the waste is monitored, before being sealed up and buried.

Officially, containers are designed to last for the full five centuries before the repository is closed. But the Environment Agency report questions whether this is "realistic" and says there is an "absence of robust arguments which demonstrate that this target is achievable in practice".

It suggests that the containers are not made of the kinds of stainless steel best able to resist corrosion and questions whether the types used are "fit for purpose over an extended time period".

It reveals that their internal surfaces are not treated to remove vulnerabilities to corrosion, and that some have seals "that are not expected to be durable over periods of hundreds of years". It also discloses that some operators have touched the steel drums with their bare hands, although the rules require gloves, depositing sweat that can also lead to corrosion.

Tens of thousands of containers already in store have been produced to less exacting specifications, which do not even attempt to make them safe for the necessary 500 years. The report adds that the implications of this do not seem to have been "fully considered". Some 17,000 containers in storage contain a kind of nuclear waste that reacts with cement and so is expected to fracture the concrete encapsulating it within 140 years.

Computer models show, the report says, that 40 per cent of the containers could fail within 1,000 years, and that under "certain scenarios" this timescale could shrink to "less than 200 years". It concludes: "It is not clear how package integrity during storage can be assured over the extended timescales now being suggested."

Yesterday, Professor Gordon MacKerron, who until recently chaired the Government's official Committee on Radioactive Waste Management, called the report "devastating". He said that it should prove a "nail in the coffin" of proposals to keep the waste accessible for hundreds of years. He said: "If we are going to dispose of the waste, this should be done as quickly as reasonably possible."

The Nuclear Decommissioning Authority will consider the report this week.
