Lesson 4: Tools Of Analysis<\/h2>\n

Definition of objectives and the scope of study<\/h3>\n
\n\n\t\t\t\t\t 1. The LCA approach
\n\t\t\t<\/path><\/svg>
\n\t\t\t<\/path><\/svg>
\n\t\t\t\t\t\t<\/summary>\n
1. The LCA approach starts by making clear what the purpose of the analysis will be and to whom (and how) the results should be communicated.
As well, data needs to be gathered for further analysis, more specifically<\/h5>\n
    \n
  1. \n
    1) Information about functional units — the processes that modify raw materials or semi-finished products and turn them into finished products; The system boundaries — which means defining the scope of what can be considered for analysis;<\/h5>\n<\/li>\n
  2. \n
    2) Allocation methods — the amount of energy or materials that go to each product individually is relevant when different products are being analyzed;<\/h5>\n<\/li>\n
  3. \n
    3)The limitations of the study or assumptions that will be made must also be acknowledged;<\/h5>\n<\/li>\n
  4. \n
    4) In the end, the impact categories that will be under investigation must be selected. Examples of such can be ocean acidification, ozone depletion, or mineral resources scarcity.<\/h5>\n<\/li>\n<\/ol>\n<\/details>\n
    \n\n\t\t\t\t\t 2. Inventory of flows.
    \n\t\t\t<\/path><\/svg>
    \n\t\t\t<\/path><\/svg>
    \n\t\t\t\t\t\t<\/summary>\n
    this essential step consists in inventorying and quantifying all the incoming flows (e.g. use of raw materials or energy consumption) and outflows (e.g. emission of polluting gases or the production of waste and\/or recycled materials), for each phase of the product life cycle.<\/h5>\n
    The final product of this phase is usually a flowchart containing all the activities’ inputs and outputs.<\/h5>\n<\/details>\n
    \n\n\t\t\t\t\t 3. Estimation of environmental impacts
    \n\t\t\t<\/path><\/svg>
    \n\t\t\t<\/path><\/svg>
    \n\t\t\t\t\t\t<\/summary>\n
    in this phase, an assessment of the whole effects caused by the flow of inputs and outputs is developed and the potential environmental impact of the life cycle under analysis is reached.<\/h5>\n
    In order to achieve this, impact categories, category indicators, and specific models must be selected.<\/h5>\n
    For instance, if the impact category is ocean acidification, a possible category indicator can be the pH level expressed by multiplying the amount of waste that enters\/leaves the system with its acidity.<\/h5>\n
    Accordingly, the flows capable of causing this impact will be analyzed and the chemical-physical models to be used will be designated.<\/h5>\n<\/details>\n
    \n\n\t\t\t\t\t 4. Analysis of the results and interpretation.
    \n\t\t\t<\/path><\/svg>
    \n\t\t\t<\/path><\/svg>
    \n\t\t\t\t\t\t<\/summary>\n
    results of the LCA are compared with the initial objectives of the study.<\/h5>\n
    This confrontation can lead to a well-founded list of recommendations with the purpose of revising the product design and optimizing its use in terms of environmental impacts.<\/h5>\n<\/details>\n
