Environmental Impact Assessment
Figure 1: Methodology for Environmental Impact Analysis
3. Results and conclusions
The program allows obtaining environmental impact data for the following categories: quality of the ecosystem, human health, natural resources and abiotic resources. The specific results of the EPS 2000 methodology for the pellet boiler establish that the depletion of resources represents 94% of the total contribution. It is also of interest that the impact on life expectancy (human health) turns out to be 4%. This impact is mainly produced by CO2 emissions. The combined action of the other two categories represents only 2%. Thus, through the EPS 2000 methodology, it is possible to identify how the greatest environmental impact during the life cycle of the boiler is identified in the manufacturing process of the boiler. This knowledge would allow acting on the selection of materials with less impact for the manufacture of the boiler, in order to reduce the overall impact of the same.
