Plasma Arc Gasification

Table of Contents:


  • Plasma Arc Gasification, or PAG, is the process of turning trash into usable byproducts through super-heating it with a plasma arc converter, or PAC.

How it works

  • Plasma arc gasification works by creating usable materials from superheated trash. The plasma torch is used to superheat the trash and melt it into usable materials.


  • The process of plasma arc gasification was invented over 40 years ago, by NASA scientists.

What it does for us

  • Plasma arc gasification is primarily used as a method of trash disposal, so its primary benefit is the disposal of waste without taking up landfill space. Eliminating the necessity for landfills is not the only benefit of PAG, though. Some byproducts of the gasification process can have other uses.

  • One byproduct of PAG is syngas, a mixture of hydrogen and carbon monoxide. PAG plants scrub the syngas and use it as energy to power the gasification process.

  • Another byproduct of PAG is slag, a solid that can be used to make bricks, synthetic gravel, asphalt, and other materials that would normally be mined from the earth.

  • The final byproduct of PAG is heat. In most plants, heat is not currently used, although some experts claim it can be used as a secondary energy source.


  • PAG is generally praised by environmentalists, but there are still a few problems. For example, the process of capturing the potentially harmful gases produced by PAG is not perfect, and harmful gasses can escape. Another problem is that PAG costs a lot more than dumping trash into a landfill or incinerator.
