5. Magliano Project : 40,000 ton/y High quality RDF
General Overview
Existing Dry Fraction production plant :
UNIECO is a 20 years concessionaire
Upgrading to High quality RDF production
Landfill expansion with biogas energy recovery

6. Magliano Project : 40,000 ton/y High quality RDF
PROJECT
Post-processing of the Dry fraction from an existing MBT plant
The system is designed in order to meet strict specification for:
Size : < 20 mm (15 mm optional) , size is controlled by the bottom sieve
Odors and Biostabilization: Ozone technology from PRAXAIR is applied
Moisture: Physical drying technology will be applied
Calorific Value: Plastic adding by weight controller has been foreseen
Chlorine: Daily lab test on automatic collected samples will be done

Electricity Cogeneration of Heat and Electricity
The plant will run using the electrical
and heat energy produced by the
landfill gas generator. The electricity
produced will be 450 kWe, together
with Heat up to 650 kWth.
