MASTER’S THESIS IN ENVIRONMENTAL STRATEGIES RESEARCH<br />
Figure 3: Conceptual frame work <strong>of</strong> def<strong>in</strong><strong>in</strong>g categories <strong>in</strong>dicator (CML, 2001)<br />
Life cycle <strong>in</strong>ventory results are analyzed based on impact categories. Characterization model and<br />
environmental impacts are considered for the model as the midpo<strong>in</strong>t analysis <strong>in</strong> the CML method. In<br />
SimaPro s<strong>of</strong>tware, CML model analyzes potential environmental impact us<strong>in</strong>g the follow<strong>in</strong>g different<br />
impact categories:<br />
• Abiotic Depletion<br />
• Acidification<br />
• Eutrophication<br />
• Global Warm<strong>in</strong>g<br />
• Ozone Layer Depletion<br />
• Human Toxicity<br />
• Fresh Water Ecotoxicity<br />
• Mar<strong>in</strong>e Ecotoxicity<br />
• Terrestrial Ecotoxicity<br />
• Photochemical Oxidation<br />
Characterization <strong>in</strong> LCA model gives the idea on how much environmental burden, the process or<br />
product contributes to the environment. Normalization value implies the level <strong>of</strong> significance based<br />
on reference normalization values. In CML method, different normalization values like West Europe<br />
(1995), Netherlands (1997) or World (1995) can be considered. In this study, West Europe (1995)<br />
values are considered for the model. Table 2 shows the different reference normalization value.<br />
