6.8.2 LIFE-CYCLE INVENTORY ANALYSIS
The LCI analysis is described in Chapter 2. Here, the existing results are used for
creating the eco-technology matrix of the environmental damage estimation for
industrial process chains.

6.8.3 LIFE-CYCLE IMPACT ASSESSMENT METHOD
The detailed results of the application of the LCIA method, eco-indicator 95, can
be found in Chapter 3, in which a comparison of the results for the two situations
based on the eco-indicator 95 is conducted. In the presented methodology, the impact
score is further applied for the dominance analysis.

6.8.4 DOMINANCE ANALYSIS AND SPATIAL DIFFERENTIATION
In the current case study, the predominant medium to which the emissions are emitted
is clearly air. The predominant pollutants are those that have been selected by
dominance analysis for the uncertainty analysis in Chapter 5. Figure 6.19 presents
the contribution of the considered processes in the LCI analysis to the total envi-
ronmental impact potential measured as eco-indicator 95. It is evident that, in this
case study, only the incineration process contributes with more than 10% to the total
environmental impact potential. Therefore, it is the only process that will be assessed
in a site-specific way by a particular study. The corresponding site is Tarragona.
The other industrial processes with more than 1% contribution will be considered
in two ways: 1) the data obtained from an IPA study of the incineration process in
Tarragona are considered valid for all processes in the Tarragona region and 2) the
remaining processes must be evaluated using damage information of similar situa-
tions obtained from the literature. The processes that contribute with more than 1%
and less than 10% to the total environmental impact are spatially differentiated in
the following way. The “production of CaO” and “treatment of ashes” processes
take place in the Tarragona region. In the LCI analysis, data for the “electricity
generation” are used from the so-called Spanish mix. The environmental impacts of
“transport” and “scrap-metal recycling” also depend on the Spanish region (see
Figure 6.19).
The results of the inventory analysis of the current situation for the relevant
processes and the selected environmental loads are presented in Table 6.6. This table
includes the eco-technology matrix with submatrices: the ELs from kWh to NO x
correspond to the first matrix for the economic damage parameter; the second matrix
for the ecological damage parameter consists only of SO and NO , and the third

matrix for the global damage parameter includes the other loads from CO to

trichloromethane (see Table 6.6).
6.8.5 FATE AND EXPOSURE AND CONSEQUENCE ANALYSIS
In the next step, the corresponding three damage-assigning matrices for the selected
three indicators are established. An attempt is made to give a particular value to
each environmental load for a specific region or site because the respective indicator
