General Overview

Upgrading to High quality RDF production

Existing Dry Fraction production plant :UNIECO is a 20 years concessionaire

Landfill expansion with biogas energy recovery

Magliano Project : 40,000 ton/y High quality RDFPROJECT

Post-processing of the Dry fraction from an existing MBT plantThe 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

Ozone Reactor

Tertiary ShredderHydraulic double rotor 7,5 ton/hMax. 12 ton/hSize < 20 mm (sieve)Optional for 15 mm sieve

Capacity: 7,5 ton/hO3 production: 10 kg/h

Plastics mixing and RDF loading systemRDF loading : 15 ton/h total to 90 m3 truckPlastic mixing : 7.5 max. ton/h

RDF Storage10 days storage0,22-0,23 ton/m3


Cogeneration of Heat and ElectricityThe 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.
