This project analyzes the advantages associated with the use of AZA steel in the context of manufacturing towers and electrical substations. The carbon footprint of several BBosch projects using AZA steel is evaluated and compared with a scenario where the same towers and electrical substations are manufactured in Turkey and imported to Chile.

Objectives:

  1. Quantify the carbon footprint associated with the galvanizing process carried out by BBosch.
  2. Quantify the carbon footprint of seven tower and electrical substation projects executed by BBosch during 2023.
  3. Quantify the carbon footprint associated with the manufacturing and importing of seven tower and electrical substation projects from Turkey, equivalent to BBosch's projects.
  4. Identify the main factors influencing the carbon footprint in each scenario.
  5. Identify the contributions to carbon footprint reduction associated with the use of AZA steel profiles.

Conclusions:

  • The "BBosch Manufacturing" scenario has a significantly lower carbon footprint (CF) than "Manufacturing and Importing from Turkey."
  • The carbon footprint per ton of AZA profiles is 87% lower than that of Turkish profiles.
  • Projects using thinner profiles (and therefore more AZA profiles) have comparatively lower carbon footprints.
  • Marine transport generates between 4% and 9% of the carbon footprint, depending on the project and the number of profiles from Turkey.
  • If the towers from 2023 had 100% AZA profiles (hypothetical case), the reduction would be 70%.
