Rusting and Leaking: radioactive waste in Australia

image from wikipedia

The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is the federal government agency for scientific research in Australia.
CSIRO faces a $30 million clean up bill after barrels of radioactive waste at a major facility were found to be “deteriorating rapidly” and possibly leaking.

An inspection found “significant rusting” on many of the 9,725 drums, which are understood to contain radioactive waste and other toxic chemicals.  Much of the radioactive waste was trucked to Woomera from Sydney in the mid 1990s.  CSIRO flagged a $29.7 million budget provision for “remediation works” at a remote location in its latest annual report.

Almost 10,000 drums of radioactive waste are stored at a CSIRO facility in Woomera, South Australia.  The Woomera facility is currently one of Australia’s largest storage sites for low and intermediate-level radioactive waste.   A damning report of the Woomera facility was issued by the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) after an inspection in April 2016.   “Evidence was sighted that indicates the drums are now beginning to deteriorate rapidly,” read the report, seen by Fairfax Media.   “Significant rust on a number of the drums, deterioration of the plastic drum-liners and crushing of some stacked drums was observed.

Tests confirmed the presence of radioactive isotopes at one location and inspectors said there was a possibility the drums were leaking.”Although unlikely, there is the possibility that the presence of deceased animals such as rodents and birds may indicate that some of the drums, which contain industrial chemicals, may be leaking into the environment.”  The mixture of water and concentrated radioactive material inside some of the drums also had the potential to produce explosive hydrogen gas, inspectors found.

They also noted CSIRO had little knowledge of what was inside many of the barrels, some of which are believed to date back more than 50 years.  “Without full knowledge [of] the contents of the drums, risks cannot be fully identified and risk controls cannot be appropriately implements to protect people and the environment,” inspectors noted in the report.

Many of the drums are understood to contain contaminated soil generated by government research into radioactive ores at Melbourne’s Fishermans Bend throughout the 1940s and 1950s.  The toxic soil was discovered by the Department of Defence in 1989, who sent it to Sydney’s Lucas Heights facility before it was palmed off to Woomera in 1994.

The country’s other major radioactive waste storage facility at Lucas Heights, Sydney, is rapidly approaching full capacity. 

Coupled with issues at the CSIRO site, the revelations highlighted the urgent need for a national radioactive waste storage solution, experts said.

An explosion at a waste dump in Benin killed eight people, local mayor Robert Tolegbon said on on September 11, 2016. The blast occurred late onat a giant trash heap in Tori, a town about 40 km north-west of the capital Cotonou, as locals were sifting for food. Previously, the health ministry said two people had died.  Safety standards for waste management are poor in much of West Africa and debris is rarely filtered to eliminate toxic or flammable materials.

How to Reincarnate E-Waste

In the electronics recycling business, the benchmark is to try to collect and recycle 70 percent, by weight, of the devices produced seven years earlier…. Apple exceeds that, typically reaching 85 percent, including recycling some non-Apple products that customers bring in.

That means Apple will have to get hold of and destroy the equivalent of more than 9 million of 2009’s iPhone 3GS models this year around the world. With iPhone sales climbing to 155 million units in 2015, grinding up Apple products is a growth business.  Apple said it collected more than 40,000 tons of e-waste in 2014 from recycled devices, including enough steel to build 100 miles of railway track.

Brightstar Corp., based in Miami, Florida, TES-AMM in Singapore, Hong-Kong’s Li Tong and Foxconn Technology Group, the most famous manufacturer of iPhones, are part of a global network of recyclers that agreed to more than 50 rules, ranging from security, to insurance, to auditing, in the destruction of the phones.

The process starts at hundreds of Apple stores globally, or online, where the company offers gift certificates to lure iPhone owners to sell back their devices….Once Apple’s partners decide a phone must be scrapped, a deconstruction process begins that is remarkably similar to Apple’s production model, only in reverse.

Apple pays for the service and owns every gram, from the used phone at the start to the pile of dust at the end, said Linda Li, chief strategy officer for Li Tong. The journey, consisting of about 10 steps, is controlled, measured and scripted through vacuum-sealed rooms that are designed to capture 100 percent of the chemicals and gasses released during the process, she said…

While some brands salvage components such as chips that can be used to repair faulty phones, Apple has a full-destruction policy.“Shredding components takes more energy than repurposing,” Li said. Li Tong works with other customers to advise on how to design products that are easier to deconstruct, taking cameras from smartphones for reuse in toy drones, and adapting screens from Microsoft Surface tablets to use in New York taxis, she said.  Apple shreds its devices to avoid having fake Apple products appearing on the secondary market.

And once it’s ground into shreds, what becomes of your old iPhone? Hazardous waste is stored at a licensed facility and the recycling partners can take a commission on other extracted materials such as gold and copper. The rest is reincarnated as aluminum window frames and furniture, or glass tiles.

The Waste that Circles the World: Canada to Philippines

Image from Philippine Bureau of Customs

Fifty containers of Canadian garbage, including used adult diapers, have been languishing in the port of Manila in the Philippines for almost two years and setting off recent protests by environmental and public health activists.The activists, among them a Catholic priest, say the containers hold toxic and hazardous waste, although a recent study by Philippines officials suggests they’re simply stuffed with household garbage.

Late last year (2014), the Philippines government recommended the containers be returned to Canada under the provisions of the Basel Convention, which prohibits developed countries from shipping waste to developing nations.“The Basel Convention says, as a developed country, (Canada) cannot export waste,” Filipino environment secretary Ramon Paje said in a televised interview. “That would be considered as dumping.”…

A spokeswoman for Foreign Affairs (Canada) reiterated the government’s long-stated opinion that the case is a private commercial matter involving a Canadian company and its Philippines partner.….Chronic Inc., a plastics exporter based in Whitby, Ontario , shipped the containers — supposedly filled with recyclable Vancouver plastics — to the Philippines in the spring and summer of 2013. But upon inspection, the country’s Bureau of Customs found the containers were filled with stinking household garbage, including used adult diapers and kitchen waste.
The bureau said the material could “pose biohazard risks” and impounded the shipment.
Jim Makris, head of the Lee-Anne Goodmandenied last year that he shipped garbage to the Philippines….The Philippine Daily Inquirer reported in 2014 that the Bureau of Customs is investigating the 150-worker plant in Valenzuela City started by Makris to sort and sell the plastic he ships.

How to Mismanage Biomedical Waste, India

biohazard

*(India) Walk past any GVMC* [civic body that governs the city of Visakhapatnam, India]  garbage dump at Ramnagar, Maharanipeta or the areas around King George Hospital (KGH) and you can be sure to spot used syringes, saline bottles or bandages strewn around dustbins.  Rag-pickers and GVMC staff rummage through these bins and stray animals litter the hazardous biomedical waste on the roads – an open invitation to HIV, Hepatitis and other infections.

Though biomedical waste should be properly segregated and then incinerated in a separate plant at Kappulupada on the city’s outskirts, in reality the norms are often flouted blatantly and hazardous waste is dumped in regular garbage bins, jeopardising the health of denizens.

To blame are the ignorance and apathy of hospital staff and those collecting the waste as they don’t segregate it properly in respective colour-coded disposal bins. As per norms, biomedical waste should be segregated at the hospital itself and put into colour-coded bins or bags. Black bags are meant for throwing remnants of food, red bags for plastic disposables such as catheter, gloves and IV fluid bottles, while yellow bags are meant for disposing human waste including used dressing pads, plaster, and needles and so on. Also needle tips need to be destroyed in needle cutters and hubs disposed of in red covers.

Commenting on the improper segregation, a senior surgeon from King George Hospital (KGH), said, “Even though the paramedics, ward-boys and staff are trained, they callously dump the waste in any bin that’s close at hand, irrespective of colour codes. There’s neither proper supervision nor any disciplinary action being taken for these acts of omission,” he said.

The lack of timely availability of colour-coded bags, especially the frequently used yellow and black bags, also poses another problem. “The bags collected from various wards are overfilled and their mouths are not tied properly. Stray dogs cause a spillage while searching food,” pointed out another senior doctor.

There are also allegations that used saline bottles are sold and syringes and needles not destroyed before being disposed. “Sometimes, hospital workers sell used saline bottles outside for Rs 50-Rs 100 and these are recycled or reused, putting public health at risk. Needles are also disposed of without breaking them in needle cutters exposing rag-pickers, GVMC sanitation staff and even our garbage collectors to the risk of HIV and other dangerous ailments if they come in contact with them. Furthermore, disposal he vehicles that carry the uncovered biomedical waste litter them on the road….

Biomedical waste should be segregated at the hospital itself and put into colour-coded bins or bags, treated and incinerated in a separate plant at Kappulupada on the city’s outskirts.

The Global Regulation of Mercury

The Minamata Convention on Mercury – a global, legally binding treaty which opened for signature today – was agreed to by governments in January (2013) and formally adopted as international law…Countries began the recognition for this new treaty at a special ceremonial opening of the Diplomatic Conference in Minamata, the city where many local people were poisoned in the mid-20th Century after eating mercury-contaminated seafood from Minamata Bay. As a consequence, the neurological syndrome caused by severe mercury poisoning has come to be known as Minamata Disease.

The Minamata Convention provides for controls and reductions across a range of products, processes and industries where mercury is used, released or emitted. The treaty also addresses the direct mining of mercury, export and import of the metal, and safe storage of waste mercury.

“Mercury has some severe effects, both on human health and on the environment. UNEP has been proud to facilitate and support the treaty negotiation over the past four years because almost everyone in the world – be they small-scale gold miners, expectant mothers or waste-handlers in developing countries – will benefit from its provisions,” said Achim Steiner, Executive Director of the United Nations Environment Programme (UNEP) and Under-Secretary General of the United Nations….Other potential impacts include impaired thyroid and liver function, irritability, tremors, disturbances to vision, memory loss and cardiovascular problems.

“With the signing of the Minamata Convention on Mercury we will be going a long way in protecting the world forever from the devastating health consequences from mercury,” says WHO Director-General Dr Margaret Chan. “Mercury is one of the top ten chemicals of major public health concern and is a substance which disperses into and remains in ecosystems for generations, causing severe ill health and intellectual impairment to exposed populations.”

Under the provisions of the Minamata Convention, Governments have agreed on a range of mercury-containing products whose production, import and export will be banned by 2020. These items have non-mercury alternatives that will be further phased in as these are phased out. They include:

•Batteries, except for ‘button cell’ batteries used in implantable medical devices

•Switches and relays

•Some compact fluorescent lamps

•Mercury in cold cathode fluorescent lamps and external electrode fluorescent lamps

•Soaps and cosmetics (mercury is used in skin-whitening products)

•Some mercury-containing medical items such as thermometers and blood pressure devices.

Mercury from small-scale gold-mining and from coal-fired power stations represent the biggest source of mercury pollution worldwide. Miners inhale mercury during smelting, and mercury run-off into rivers and streams contaminates fish, the food chain and people downstream.  Under the Minamata Convention, Governments have agreed that countries will draw up strategies to reduce the amount of mercury used by small-scale miners and that national plans will be drawn up within three years of the treaty entering into force to reduce – and if possible eliminate – mercury.

The Convention will also control mercury emission and releases from large-scale industrial plants such as coal-fired power stations, industrial boilers, waste incinerators and cement clinkers facilities.

How to Break Toxic Ships: send them to another country

MV "HANSA BRANDENBURG.  Image from Black Sea News

WWF-Pakistan has warned Pakistan against the import of a European ship, which is suspected to have burnt containers and cargo that may contain a substantial amount of hazardous materials such as heavy metals or PCBs.  Moreover, the vessel is suspected to carry dangerous substances in fire fighting water as well as a significant amount of fuels and oil. This container ship caught fire in July (2013) and was later towed to Port-Louis in Mauritius. (MV “HANSA BRANDENBURG”,).MV Hansa Brandenburg is a 2002-built Liberian-flagged container ship operated by the German shipping company Leonhardt & Blumberg.

WWF-Pakistan considers that this ship if imported to Pakistan may cause severe marine pollution in the Gadani area, which is already stressed because of a number of economic and industrial activities. Unplanned construction such as Fish harbour has already had serious environmental impact in the area, which is also designated as energy corridor and construction of power plants may have impact on the marine environment of the area unless proper mitigative measures are taken. According to WWF-Pakistan Technical Adviser (Marine Fisheries) Muhammad Moazzam Khan, the area of the Gadani is a part of Sonmiani, which is considered to have a rich marine biodiversity especially around Churna and Kaio islands. Dumping of toxic waste might seriously harm the fragile ecosystem of the area.
