Eco Audit tool

The Eco Audit tool estimates the energy used and CO₂ produced during the key life phases of a product (material, manufacture, transport, use, and end of life), and identifies which phase has the dominant contribution.

This is the starting point for eco-aware product design, as it identifies which parameters need to be targeted to reduce the eco-footprint of the product.

The next few exercises will take you through a case study for a brand of bottled mineral water. It is sold in 1 liter PET bottles with polypropylene caps. A bottle weighs 40 grams, the cap weighs 1 gram. Bottles and caps are molded, filled, and transported 550 km from the French Alps to England by a 7.5-16 tonne truck, refrigerated for 2 days and then sold. The overall life of the bottle is one year.

An example product file for this case study is installed with Granta EduPack in the Samples folder, with the filename Level 2 - Bottle PET.prd. Eco Audit .prd files can only be opened and saved from the Eco Audit tab, and are saved separately from selection project files (.ces).

Note: The Enhanced Eco Audit tool contains warnings about restricted substances, and options to include a cost analysis or a secondary process in the audit. For more information on these advanced features, see the Help or the teaching resources for EduPack on the Ansys Education Resources site.
