Case 4 Soil retaining wall
LCA Studies
The use of Geosynthetics leads to lower impact in all categories:
-
~ 75% reduction of non-renewable cumulative energy demand (CED).
-
~ 85% reduction of cumulative greenhouse gas emissions.
-
Every 3 linear meters soil retaining wall (3 meter high) saves 30,000 MJ eq, which is equivalent to the energy consumption of one household per year.
