Gasification can be accomplished using MASS BURN
techniques which is in fact the most widely used
methodology throughout the US and EU. High tech
incineration as well as collection techniques from
landfill gasses are effective and commonly employed due
to their relative costs compared to plasma ( the most
expensive) and pyrolysis.

is clearly thought to be the way of the future in both
terms of efficiency and the environment.
Gasification is a flexible and clean energy technology
that can turn a variety of feedstock into energy, helping
to reduce dependence on carbon based energy
sources providing a clean alternative source of electricity,
fertilizers, fuels, and other useful by-products. Gasification converts
almost any material into a useable and efficient gas
(syngas). The syngas can be used to produce electricity
directly, via gas turbines or used to produce liquid fuels, bio
fuels, a substitute for natural gas (SNG), or hydrogen.
There are more than 140 gasification plants operating
worldwide. Nineteen of those plants are located in the
United States. Worldwide gasification capacity is
projected to grow 70% by 2015, with 80% of that growth
occurring in Asia.
There are many companies producing gasification
technologies. There are two main types of gasification;
Pyrolysis and Plasma Arc.

thermo chemical decomposition of organic material at
elevated temperatures in the absence of oxygen.
Pyrolysis typically occurs under pressure and at
operating temperatures above 430 °C (800 °F). The word
is coined from the Greek-derived elements pyr "fire"
and lysis "separating". Pyrolysis is a special case of
thermolysis, and is most commonly used for organic
materials. The Pyrolysis or gasification of wood, which starts at
200–300 °C (390–570 °F), and occurs naturally for example when
vegetation comes into contact with lava in volcanic
eruptions. In general, pyrolysis of organic substances
produces gas and liquids leaving a solid
residue richer in carbon content. Extreme pyrolysis,
which leaves mostly carbon as the residue, is called
or PLASMA ARC

Plasma arc gasification is a waste treatment technology
that uses very powerful electrical energy creating
extremely high temperatures
by an electric arc. This is like a continuous lightning
bolt and instantly breaks
down all material into elemental gas and limited
solid waste (slag), in a device called a plasma
The process has been intended to be a net
generator of electricity, depending upon the composition
of input wastes, and to dramatically reduce the volumes of waste
sent to landfills. Relatively high voltage,
high current electricity is passed between two
electrodes, spaced apart, creating an electrical arc.
Inert gas under pressure is passed through the arc into
a sealed container of waste material, reaching
temperatures as high as 25,000 °F (13,900 °C) in the arc
column. The temperature a few feet from the torch can be
as high as 5,000–8,000 °F (2,760–4,427 °C).
temperatures, most types of waste are broken into basic
elemental components in a gaseous form, and complex
molecules are separated into individual atoms. The
reactor operates at a slightly negative pressure,
meaning that the feed system is complemented by a
gaseous removal system, and later a solid removal
system. Depending on the input waste (plastics tend to
be high in hydrogen and carbon), gas from the plasma
containment can be removed as syngas.
