  • Nonthermal plasma reactors and plasma chemistry

    The main goal of this paper is focused in reviewing the last 22 years of the use of nonthermal plasma reactors as alternative technologies for the treatment of residual fluid substances, regarding the destruction of hazardous compounds or the synthesis of other valuable compounds. The electrical discharge processing has emerged as alternative plasma-based technologies. Electrical discharges can ...

  • Plasma Methods for Technology Processing of Toxical Industrial Wastes

    Experimental study of thermal neutralization of some toxic chlorine and bromine industrial wastes, as well as of pesticides with a expired term of validity was carried out in the three-jet plasma reactor . Different physical-chemical methods were used for analysis of products of waste processing. It was shown that plasma technology provides effective processing of toxic ...


  • Atomic Layer Etching – Changing the Art of the Possible

    The society of vacuum coaters (SVC) deserves to be better known. It was founded in 1957 during a surge in the use of vacuum coating techniques such as sputtering and evaporation. The techniques go back a very long way: that man Edison filed a patent for coating phonograph cylinders in 1892 (It will never catch on). Did you know that the shiny surface inside your crisp packet is a vacuum ...

  • Let’s talk plasma

    Usually when I attend a conference on behalf of Tetronics I am about the average age of the other delegates. Not this time. Suddenly, I am old enough to be the father of most of the other people here, because this is a university-based conference hosted by the University of Liverpool. Yes, this is the snappily-titled International Workshop on Plasmas for Energy and Environmental Applications, or ...

  • UV LEDs making waves with clean water

    Oxford Instruments systems now facilitate water purification technology With World Earth Day last week I’ve decided to make this weeks blog about how new technology is being used to enhance people’s lives in a fundamental way. The UN recognises that clean drinking water is a global issue with over ...

  • Keeping APCr out of Landfill

    The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the ...

  • The Plasma Processing of Steel Plant Wastes

    ABSTRACT: Electric arc furnace (EAF) dusts, have been successfully treated in plasma-fired carbothermic reduction furnaces to recover metal values. Although the technology is equally applicable across the range from plain carbon to stainless steels, historically, it is the latter that has been the more commercially successful. Because the plasma heat source is independent of process chemistry, ...

  • Odour control with Direct Cold Plasma

    Odour emission during the production or processing of food and feed is often an unwelcome side effect. However, by using cold plasma technology, the smell can be reduced up to 95%. Increasingly, feed manufacturers are being required to address the issue of emitting of odour and harmful contaminants into the surrounding community. Local communities, special interest groups and government ...

  • Plasma gasification: Harnessing the power of lightning

    Plasma gasification is both a high-tech solution to the problem of waste management and a source of renewable power. The technology has great potential, but can it move from the fringes to the mainstream? The name "plasma gasification" conjures up images of men in lab coats late at night, investigating a far-flung corner of science that is light years away from commercial readiness. In reality it ...


  • CIWM Feature: Plasma Power - Dr Deegan gives a flavour of what plasma technology can offer

    Sustainability… what does this mean? It is often a term that means many different things to different people and organisations based on their perspective. When examined in detail, the definition is quite complex, something that Chartered Environmentalists will be more than familiar with. It is also something that is linked into addressing concerns around the subjects of strategic ...

  • Waste Advantage Magazine- The use of Thermal Plasma Technology for treating APC Residues

    The  growth in Energy from Waste plant capacity is leading a corresponding increase in the generation of Air Pollution Control (APC) Residues, making it one of the fasted growing waste sectors in the UK. In this article published in Waste Advantage Magazine, Dr Tim Johnson from Tetronics discusses how plasma technology is one solution to this ...

  • New Paper: Atomic layer etching using advanced plasma etch technology

    Scientists at Plasma Technology demonstrate Atomic Layer Etching (ALEt) of Silicon, using advanced technology  and plasma process knowledge. Read the article in JVST by Andy Goodyear and Dr Mike Cooke, Oxford Instruments Atomic layer etching using plasma is a cyclical etching process of gas dosing and surface bombardment that removes material layer ...

  • Garbage to Gold: Breakthrough Technology Uses Plasma to Convert Waste to Useable Products

    A breakthrough technology that uses high-temperature thermal plasma to turn household garbage into a renewable energy source, scrap metal and mineral wool is attracting worldwide attention for Huntsville-based Plasma Waste Recycling. […]  The PWR process doesn"t involve combustion, but a gasification process that is ...


  • Plasma resource recovery technology –converting waste to energy and valuable products

    Abstract Plasma Resource Recovery (PRR) is a revolutionary technology that can treat virtually any type of waste by combining gasification with vitrification. Vitrification produces inert slag that can be used as a construction material. Gasification produces a fuel gas containing carbon monoxide (CO) and hydrogen (H2), used for cogeneration of electricity and steam. The plasma fired ...

  • The use of thermal plasma technology for treating air pollution control residues

    Energy from waste (EFW) is an exciting industry to be in right now in the UK. As pointed out by Euston Ling and Dr. Adam Read's article "The Shifting Landscape for Renewable Energy in the UK" {Waste Advantage Magazine, June 2011), the EFW capacity in the UK is set to grow strongly in the next 10 years, with some commentators predicting a three-fold increase in EFW capacity from the current 4 ...
