    Israeli discovery converts dangerous radioactive waste into clean energy

    Israeli discovery converts dangerous radioactive waste into clean energy
    By Karin Kloosterman March 18, 2007

    The laws of conservation of energy and mass say that energy or mass cannot be created or destroyed - only change form. With the help of Russian scientists, Israeli firm Environmental Energy Resources (EER), has taken the laws of science and turned them into a useful invention for mankind - a reactor that converts radioactive, hazardous and municipal waste into inert byproducts such as glass and clean energy.

    The problem of radioactive waste is a global one, and getting increasingly worse. All countries in the industrialized world are waking up to the need for safer hazardous waste disposal methods.

    "In the beginning, nobody believed that we could do it," says Itschak Shrem, chairman of investment company Shrem, Fudim and Keiner representing EER at a press briefing announcing the innovation last week in Tel Aviv.

    Shrem, himself an invoker of small miracles through the founding of one of Israel's most lucrative venture capital funds - Polaris (now Pitango) - points to a chunk of black, lava-like rock sitting on the table in front of everyone's coffee cups.

    The journalists cautiously eye Shrem as he assures them that the shiny dark material, emitted from EER's pilot waste treatment reactor near Karmiel in the north, is safe to touch.

    "It also makes a good recyclable material for building and paving roads," he assures them. Earlier, Shrem told ISRAEL21c that EER can take low-radioactive, medical and municipal solid waste and produce from it clean energy that "can be used for just about anything."

    Using a system called plasma gasification melting technology (PGM) developed by scientists from Russia's Kurchatov Institute research center, the Radon Institute in Russia, and Israel's Technion Institute - EER combines high temperatures and low-radioactive energy to transform waste.

    "We go up to 7,000 degrees centigrade and end at 1,400 centigrade," says Moshe Stern, founder and president of the Ramat Gan-based company.

    Shrem adds that EER's waste disposal rector does not harm the environment and leaves no surface water, groundwater, or soil pollution in its wake. The EER reactor combines three processes into one solution: it takes plasma torches to break down the waste; carbon leftovers are gasified and inorganic components are converted to solid waste. The remaining vitrified material is inert and can be cast into molds to produce tiles, blocks or plates for the construction industry.

    EER's Karmiel facility (and its other installation in the Ukraine) has a capacity to convert 500 to 1,000 kilograms of waste per hour. Other industry solutions, the company claims, can only treat as much as 50 kilograms per hour and are much more costly.

    According to the journal Research Studies (Business Communications, Inc.), 'The production of nuclear weapons/power in the US has left a 50-year legacy of unprecedented volumes of radioactive waste and contaminated subsurface media and structures... Nuclear waste generators include the national laboratories, industrial research facilities, educational and medical institutions, electrical power utilities, medical diagnostics facilities, and various manufacturing processes.'

    In the US alone, Research Studies predicts that this year's market for radioactive waste-management technologies in America will cap $5.5 billion.

    EER was founded in 2000 and has maintained a low profile until revealing its reactor last week.

    "We spent our time on R&D and building up the site in Israel which we started constructing in 2003. We realized that nobody was going to believe us unless we started doing the process physically. They always said it sounded too good to be true, so we had to prove it to them," said Shrem.

    Back in 2004, the Ukrainian government put out a tender searching for a solution that would provide safer hazardous waste disposal methods. At that time, the country was looking for a way to treat its low-radioactive waste zones resulting from the Chernobyl explosion. EER sent in their proposal, and their technology won the bid.

    According to Stern, the former Soviet Union was the first to build nuclear plants. Over the years they have generated "huge amounts of low-radioactive waste. They came to us looking for a solution," he said.

    The Chernobyl nuclear meltdown on April 26, 1986 - was beyond a doubt the largest civil nuclear explosion in the world and one still linked to thousands of deaths. More than 20 years after the explosion, tens of kilometers around the reactor is still highly radioactive; and some 30,000 radioactive homes remain buried along with household appliances, food and clothing, explained Stern.

    "The European community is afraid of what is happening there," notes Stern, warning that it is time for the clean up to begin, even if it means making only a small dent in the massive pile. "The low-radioactive waste is slowly contaminating the water and will continue to do so over the 300 years it takes to break down."

    And since new conventions have been set by The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal, first world countries are no longer permitted to traffic their hazardous waste to third world nations - forcing Western countries to drum up immediate and responsible solutions.

    With a strict eye over its operations by Israel's Ministry of Environmental Protection, EER revealed its proof-of-concept to Israeli and foreign dignitaries in Aeblin, near Karmiel last week, showing how it can take mountains of municipal waste and reduce it to a pile of black rubble.

    "We are not burning. This is the key word," Shrem said. "When you burn you produce dioxin. Instead, we vacuum out the oxygen to prevent combustion."

    EER then purifies the gas and with it operates turbines to generate electricity. EER produces energy - 70% of which goes back to power the reactor with a 30% excess which can be sold.

    "In effect, we are combining two of the most exciting markets in the US - the environment and clean energy," says Stern, "We also reduce the carbon footprint."

    The cost for treating and burying low-radioactive nuclear waste currently stands at about $30,000 per ton. The EER process will cost $3,000 per ton and produce only a 1% per volume solid byproduct.

    In the US, EER is working to treat low-radioactive liquid waste and recently contracted with Energy Solutions, the largest American company in the field with 75% of the US market.

    Based on the financial forecasts, EER is certainly giving a fresh meaning to the expression - one man's garbage is another man's treasure. But in EER's case, ones man's hazardous waste may very well be EER's goldmine.

    Looks like this is a breakthrough. With this maybe nuclear power plants will be used more without much worry of waste.

    Note that this is only for low level radioactive waste. The really bad stuff is still a big problem. I've seen something like this before, where they melted low level waste into a kind of inert glass that could be used for building and paving. Highly radioactive stuff still needs secure storage, or preferably to be converted into less radioactive stuff via nuclear reactions. Unfortunately we haven't really worked out the latter solution yet, and the former leads to the question "Where?" and the inevitable answer "NIMBY!"
    I enjoy being wrong too much to change my mind.

    So this gasifies the low-level waste, burns the Syngas to produce energy and then vitrifies the solid waste? I'm not seeing how this is all that much of an improvement. You're potentially turning low-level waste which you can just landfill into medium-level waste which you have to treat rather more carefully, and furthermore you risk discharging a small amount of radioactive ash to atmosphere.
    Looks suspiciously like a news article written from a press release by a hack with virtually no nuclear knowledge. I would also note that the costs are rather misleading - quoting $30,000/tonne for disposal versus $3,000/tonne for one part of the treatment process, and thus implying that their process is cheaper without saying what is done with the solid waste they produce.

    Rule 2: Treat all members of the press as French

    True, but this is still a sign of progress, maybe a small step or maybe not even a step, but progress in my opinion.

    There is an American company doing the exact same thing. The dude that invented the trash compactor came up with it. Same torch and all. It is in pop sci or pop mech like two months ago.

    Amazing... I hope to see this corroborated by others in the scientific community. If accurate, it would truly be a huge breakthrough.

    This information can be found on official Israel government websites, so perhaps it is very much true. If the process and its results as described are accurate, costs could be decreased via economy of scale.

    Perhaps this process could also be used for coal and oil power plants?

    Ironduke, of all chaps, I would have thought you the last to grant this tosh credence!
