The RDF production from MBT process

• The production of SRF represent the “evolution” of MBT process

• It is fundamental to identifythe final users to reduce the cost

• Reduction of landfill use

The good example: The Fusina plant

• Veritas is an integrated wastemanagement plant that include MBT process and matter recovery

• The plant treats all the wastecoming from Venice and itsneighborhood

• Low level of separate collection

• Production of RDF

• Sinergy with Enel Power plant

Veritas plant: flow chart

The use of biocell

The pellets production

The production of electric energy

• Close to Veritas plant = reduction of the cost

• Co-combustion with coal

• Total amount burned in 2013 = 62.000 t

• Dedicated controls in order to verify the quality of the emission

Average costs for MBT process in Veneto

• Our analysis confirm a treatment costs of 30/60 €/t

• Other relevant cost:• Management of scraps (into landfill) = 50-80 € /t in Veneto

(2012)

• Management of light scraps (incineration cost) = 80-95 €/t in Veneto (2012)

• Total average cost: 100/130 €/t

Are these costs sustainable?Are these costs competitive to other solution?

Conclusion and lesson learnt

• MBT process is very flexible and can face a wide range of situation

• It is fundamental to reduce the amount of biowaste into landfill

• In case of high rate of separate collection it is possible to convent the plant to:• Compostin process / Anaerobic digestion• SRF production

• The economic balance is possible only when the user is close to the producer and without dedicated plants

1988 2014Planning process

• MBT plant is a part of the solution

• MBT should be used to achieve only a part of the EU target

• Separate collection must be developed in cooperation with MBT

• Evolution to SRF including Industrial waste

• The landfill ban for untreated waste

• The ecological tax on untreated/unseparatedwaste
