Life Cycle Assessment (LCA) del progetto Green Site

  1. 1. Project GREEN SITE “Supercritical fluid technologies for river and sea dredge sediment remediation” – LIFE 10 ENV/IT/343 – Federico Giovannone – eAmbiente Srl Federico Balzan – eAmbiente Srl
  2. 2. Index of the presentation LCA and CF Goals Methods Results 7a - LCA of the prototype 7b - Carbon Footprint of the decontamination 7c - Environmental benefits of the proposed technology Conclusions
  3. 3. LCA and CF What are they? LCA (Life cycle assessment) is an objective method for the assessment and quantification of energy and environmental 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.
  4. 4. LCA and CF What are they? 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.) Carbon footprint Carbon Footprint is actually a part of an LCA.

  6. 6. Results 7a - LCA of the prototype 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.
  7. 7. Results 7a - LCA of the prototype Modelling: Each input and output has been verified through mass balance outgoing and incoming
  8. 8. Results 7a - LCA of the prototype 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 subprocess in relation to the boundaries of the system. First step: • Type of material • Industrial Processes • Weights Source: Board materials or measurements in field Second step: • Collection of all inventory and allocation of flows for all processes
  9. 9. Results 7a - LCA of the prototype Third step: Creating the Model in SimaPro
  10. 10. Results 7a - LCA of the prototype 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.

The treated sediment from the project Green Site Colonna B Use not in direct contact as materials in the lagoon of Venice for the creation of mudflats, salt marshes, morphological recovery. Colonna C Destination at the site of the island of Tresse. Reference scenario for comparison Over Colonna C Destination as reclaimed materials in the “Molo Sali” site. Over Colonna C, dangerous Destination as waste at the “area 23 hectares” and subsequent disposal at the landfill "Moranzani"

  25. 25. Results 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 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.
