  • 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 ...

  • FAQ About Plasma Arc Gasfication Process from Plasma Waste Recycling, Inc (PWR)

    What is Municipal Solid Waste? Municipal solid waste (MSW)—more commonly known as trash or garbage—consists of everyday items such as product packaging, grass clippings, furniture, clothing, bottles, food scraps, newspapers, appliances, paint and batteries. It does not contain industrial, hazardous, or construction waste. Since 1980, the total annual volume of MSW generated in the U.S. has ...


  • Decomposition of benzene by non-thermal plasma processing: Photocatalyst and ozone effect

    Plasma technology has some shortcomings, such as higher energy consumption and byproducts produced in the reaction process. However non-thermal plasma associated with catalyst can resolve these problems. Therefore this kind of technology was paied more and more attention to treat waste gas. A hybrid system comprising a non-thermal plasma reactor ...

  • Nonthermal Plasma Applications to the Environment: Gaseous Electronics and Power Conditioning

    Abstract—For nearly two decades, interest in gas-phase pollution control has greatly increased, arising from a greater respect for the environment, more attention to the effects of pollution, and a larger body of regulations and laws. Nonthermal plasma (NTP) technology shows promise for destroying pollutants in gas streams and cleaning contaminated surfaces, using plasma-generated reactive ...

  • Pyrolysis processing of used old tyres by thermal plasma technology

    Thermal plasma pyrolysis of used old tyres was studied in a nitrogen plasma reactor in order to evaluate the material and energy recycling potential. The main gaseous products from thermal plasma pyrolysis of used old tyres were identified by chromatography as H2, CO, CH4, C2H2, ...

  • A combined process of non-thermal plasma with sludge stabilization for the simultaneous reduction of odor and organic waste

    Odor emissions and sludge disposals have become most challenging issues in many sludge treatment plants, and separate chemical oxidation processes have been commonly employed for these problems. It is, therefore, necessary to develop a combined process that simultaneously reduces the odor emissions and the amount of waste sludge. In this study, a non-thermal plasma reactor using a dielectric ...

  • Nano-textured polymer surfaces with controlled wetting and optical properties using plasma processing

    Wettability control is of great importance in many applications, from manufacturing of water repellent surfaces to droplet frictionless motion in microfluidics, and biocompatibility tuning. Wetting or repellent behaviour is governed by both surface chemistry and topography. In particular, super-hydrophobicity is attained by combining high-aspect-ratio (HAR) geometrical characteristics with low ...
