Radical 7000 Degree Celsius Plasma Reactor Converts Hazardous Medical and Radioactive Waste to Energy and Useful Products

Garbage and hazardous waste are becoming valuable energy feedstocks, thanks to researchers from Ukraine, Russia, and Israel. Even low level radioactive wastes, medical wastes, and toxic wastes can be converted to useful products and energy, using a new high temperature plasma reactor.
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 has said 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 including building and paving roads.

Shrem added 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 uses plasma torches to break down the waste; carbon leftovers are then gasified and finally 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.

"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.__NextEnergyNews
This is but one of many exciting new "garbage to energy" processes coming on line currently, and within the next year or two.

Safe conversion of toxic waste, medical waste, and radioactive waste that also produces energy and useful materials for construction, would appear to be exactly what environmental groups such as Greenpeace, the Sierra Club, Earth First and WWF would promote. Unfortunately, many of those groups have more mundane monetary and power concerns other than actually making the environment better. Watch and see what they are actually promoting, as opposed to what they ignore. A cleaner, more energetic world may not be what they actually want.

I expect those folks would be horrified at the prospect of the gravy train being derailed.

There will be lots of people who will lend their support to stopping all these sorts of projects due to the inability of most people to comprehend that there is a difference between incinerating something at 7000 degrees and just putting it in a can and setting it on fire.

These links have been on my site for awhile and I think they re-enforce your article:

Yep, for most of them, it's all about the money, S-Woman.

Baron, the plasma melting process takes place in the absence of oxygen, which is even more differentiated from conventional incineration.

Thanks for the links, Bruce.

Energy from garbage, and toxic waste remediation, are both important processes. If you can get both from the same plant, all the better.

If the temperature in the reactor exceeds 7000 degrees, which material can withstand such a temperature?

If the temperature in the reactor exceeds 7000 degrees, which material can withstand such a high tempetature? Or is it like the heat is being withdrawn continuously?
