shows, at least for now, this is a mind that has space
only in the ideal world.

“The plant has the function of
disposing, through the waste-to-
energy process, of the fraction with
fuel value contained in municipal
waste and similar to non-hazardous
urban waste downstream of the
separate collection

Therefore, waste-to-energy is the combination of
various processes aimed at achieving this following
goals:
• Optimal waste combustion;
• Production of electrical energy with high
thermodynamic efficiency;
• Minimize emissions in the environment.
“The plant, installed in Sardinia, has Fuctional sectors
The main processes which interact are: a nominal capacity of about 61000
• Preservation of the heat load and waste t/year of waste with an average
combustion; calorific heat of 13188 KJ/kg
• Temperature at the end of the post-combustion
chamber (T ); agricultural areas and deciduous forests. The plant

• Denitrification of the flue gases. The revamping project of the Macomer plant, costed
