Conclusions

LCA and CF

LCA (Life cycle assessment) is

an objective method for the

assessment and quantification

of energy and environmental

loads and the potential

What are they?

loads and the potential

impacts on environment of a

product/process/activity over

the entire life cycle, from raw

material acquisition to the

end of life.

LCA and CF

CF (Carbon footprint) is an

evaluation throughout the life

cycle of a product in relation

to the impact category

"Global Warming" (expressed

in CO2 eq.)

What are they?

Carbonfootprint

Carbon Footprint is actually a

part of an LCA.

Results


Functional unit: the prototype, considering every phase of the construction project and disposal.

System boundaries: LCA is conducted by defining product systems as models that describe the key elements of

physical systems. The system boundary defines the unit processes to be included in the system.

Results


Modelling: Each input and output has been verified through mass balance outgoing and incoming

Results


Life cycle inventory (LCI): the determination of material and energy flows, taking into account the entire life of the

product. The flows of materials and energy are then determined based on the income and expenditure of each sub-

process in relation to the boundaries of the system.

First step:

• Type of material

• Industrial Processes

• WeightsSource: Board materials

Second step:

• Collection of all

inventory and

allocation of flows for

all processesSource: Board materials

or measurements in fieldall processes

Third step: Creating the Model in SimaPro

Results


Impact assessment of the life cycle (LCIA)

Assessment (according to specific environmental parameters and methods) of the flow of material and energy

calculated during the inventory analysis: this estimate is intended to detect, summarize and quantify the possible

environmental effects of the systems examined, as well as to provide essential information to their evaluation.

Conclusions

The analysis of the life cycle (LCA) of the prototype has shown, being very limited the use phase, a

charge of environmental impacts at the stage of production and assembly of the prototype

(including processes of raw material extraction and manufacturing inputs).

It was found, however, that in case of treatment of only 100 m3 (in projection) the impact of the

construction of the prototype falls below 10 %, going to amortize the initial investment.

The use phase showed an energy consumption as a function of the total weight of dredgedThe use phase showed an energy consumption as a function of the total weight of dredged

sediments and/or processed (t) very different from Green Site scenario and Tresse Island scenario. As

is obvious, however, the two services are very different.

The total environmental impact assessment (EIA) has shown clear advantages in Green Site scenario,

especially for the critical aspect of redistribution of sediments, fundamental in the Venice lagoon. It

remains to dissolve the critical aspect of energy consumption, which could presumably decrease if the

project was industrialized on a large scale.
