[GreenYes] Thermal Waste Treatment lnown outcomes of system using oxygen highly inefficent



And economically and environmentally unacceptable!
This is in practice what the Star Tech and Westinghouse system does but
without flame or Oxygen.
Thermal Waste Treatment: a Better Approach
Calaminus B., Stahlberg R.
Chemtech 1998, October, 40-46 (Eng.)
The Thermoselect High-Temperature Recycling process combines slow
compression, degassing, fixed-bed oxygen blown high temperature gasification, and
mineral and metal residue smelting in a closed-loop system to completely
transform municipal, industrial and other kinds of waste into directly usable
products. The Thermoselect process is presented on a diagram; the most important
chemical reactions taking place at each step of this process are listed on
another diagram. The article also contains a figure listing all steps for the
complete Thermoselect process. One metric tonne of waste and approximately 500 kg
of oxygen yields: 890 kg of synthetic gas (that could be used for conversion
into electricity, or as a substrate for chemical synthesis), 350 kg of water
used for cooling, 230 kg of carbon-free vitrified minerals (for use in
various industrial applications), 29 kg of ferrous metal alloy granulate for
reintroduction into the iron or copper industry, 10 kg of industrial quality NaCl,
3 kg of non-ferrous metal concentrate (mainly zinc and lead), and 2 kg of
industrial quality sulphur. The article also gives three examples of actual
implementation of the aforementioned process in plants located in Karlsruhe,
Ansbach, and Hanau, Germany.
Presented herein in support of further informed discussion of High heat non
incineration method of recycle proposed earlier.
