Case 5 Waterways

LCA Studies


The use of Geosynthetics leads to lower impact in all categories:


  • Greenhouse gas emissions are reduced by 12 to 26% through the use of geosynthetics

  • The cumulative energy requirement is reduced by 13% to 28% through the use of geosynthetics


At the same time, the use of geosynthetics generate cost savings (see graph below)

This study shows

​The use of geosynthetics leads to: 

  • 25% (min.) lower environmental impact for all indicators

  • ~ 25% lower non-renewable cumulative energy demand

  • ~ 20-30% lower cumulative greenhouse gas emissions

  • ~ 20% costs saving, as compared with conventional methods

LCA Case 5

Cross section

The functional unit is 1 meter of an inland waterway with a width of about 34 meters (water level, see below). The upper layer consists of water stones in both cases. The filter layer is either gravel/sand of two times 20 cm (left side figure) or a geosynthetic filter (right side figure)
