Food industry waste energy recovery by
thermal plasma process

This paper presents the experimental results of food
industry waste processing for energy recovery using
thermal plasma technology. The thermal plasma is a
technology where a gas is superheated and temperatures up
of 15,000 ° C can be reached . In this temperature range, the
superheated gas does not meet any of the properties of the
solid, liquid or gaseous, which causes the plasma is called the
"fourth state of matter." The heating of this gas occurs through
an electric arc in operation in controlled conditions to achieve
greater energy efficiency. Energy is applied to a reactor where,
under controlled conditions, gasification of the waste occurs.
In these temperatures, there is a molecular disassociation of
all gaseous materials, which increases the extractable energy
of the gasification process, as compared to other known
processes such as incineration, pyrolysis or gasification
by other thermal processes. A very important feature and
inherent thermal plasma process is the total destruction of
the processed material, not generating, after processing, any
type of waste requiring a specific disposal. processes. A very
important feature and inherent thermal plasma process is the
total destruction of the processed material, not generating,
after processing, any type of waste requiring a specific
disposal. Typically, the process residue with the thermal
plasma, we gas production, generation of a metal layer (if any
metals in the waste) and generating a vitrified phase material
not all gassing. These metal and glazed phases are totally inert
and may have specific disposal. The metallic phase may be
marketed for the metalworking industry and the vitrified
phase can be discarded or used as gravel for paving filling or
other uses in the construction area. The energy released by
the process gas can be utilized for generating steam, with the
use of a combustion chamber and a boiler. Depending on the
need of energy matrix where the processing is occurring, it
is also possible to use a system with a steam turbine and an
electrical generator to provide electrical energy.
