The LCA of the associated product system has been based on the primary data from the BMI production facilities in Germany (Capeller Strasse 150, 59368, Werne) and the United Kingdom (Barton Dock Rd, Trafford Park, Stretford, M32 0YL, Manchester). Background data has been based on primary environmental data and Ecoinvent 3.6 database.
Product overlap when installing has been estimated at 10% of the products length and 6% of its width. |
