Waste Plasma Processing Technology In The World

The problem of household and industrial waste recycling is acute, but it seems that plasma technology can be the right panacea to all the problems in the nearest future. Simdean, the innovator of industrial waste disposal, plasma waste disposal and a well-established industry researcher, continues to acquaint you with the news, advances and major events of plasma waste technology. Today’s article focuses on one of the most prospective regions as for plasma technology usage – Russia.

The state of affairs

Russia annually produces about 3.8 billion tonnes of waste. On average, 10% – 15% of garbage is recycled. Municipal solid waste is processed by only 3% – 4%, industrial – by 35%. Basically garbage dumped in landfills – there are over 11,000 of such areas in the country. They store about 82 billion tons of waste. That’s a significant figure.

Currently, this technology is being promoted and developed by a team of associates of specialized research Institute of Instrumentation (SNIIP) under the direction of Valery Gnedenko. Apart from doctors recognized by the Russian community the team includes experts from a number of international scientific organizations. Their main is to promote technologies for plasma processing waste using domestic equipment both inside Russia and around the world, including Europe, the USA and Japan. The results are impressive so far, 11 new facilities were launched since 2014, altogether allowing to process 10 million tons of waste monthly.

Why plasma processing

One of the most innovative ways of recycling, plasma gasification, is applied due to an impressive array of advantages over existing technologies, such as:

  1. No need in sorting
  2. The absence of harmful compounds (dioxins and furans) after processing
  3. The ability of recycling medium and low radioactivity, as well as disposal of hazardous chemical plants, hazardous medical waste.
  4. Generation of electricity and heat in the effluent synthesis gas.
  5. The ability to obtain diesel fuel of EURO class.
  6. The high-tech products from basalt residue, such as basalt mats for insulation, basalt fiber, basalt textiles and glassware.

Thus the use of this technology allows almost refuse from landfilling of certain materials, with the exception of processing medium and weakly radioactive waste. When processing low and medium radioactive waste using this technology, the volume of waste is reduced by hundreds of times.

The technology consists in the fact that under the influence of the plasma and high-temperature waste is transferred into gaseous and partially liquid forms at temperatures over 1300C. In these conditions the formation of dioxins and furans (this statement is confirmed by tests) is impossible. In consequence of such waste heat break elemental. In the process of cooling the solid component of the waste is obtained with molten vitrified slag (which in its composition is close to natural basalt). In the case of processing of medium and weakly radioactive waste vitrified basalt slag dissolves in itself and accumulates radioactive elements, thus completely excludes emission of radioactive elements in the atmosphere. Later vitrified slag is disposed at specialized stores . Fuel gas, as mentioned, is directed for processing, and depending on the selected mode of operation of the enterprise electric, thermal energy or synthetic liquid fuel can be obtained as a secondary product.
