AG Ingenieurökologie - Recycle-KBE


Brief Description

In the project, the possible uses of substitute building materials in the context of the construction of Urban Green Infrastructure were investigated. In addition to the technical construction suitability of the materials and the fulfilment of environmental protection requirements, the aspect of the greening capability of these materials and their multifunctionality are also important. The project pursued the overarching goal of investigating the feasibility of replacing the primary raw materials previously used, such as gravel and crushed stone or topsoil, in construction applications with substitute building materials and to identify the resulting potential for strengthening the circular economy in Saxony-Anhalt, Germany. The mineral components of a geogrid-reinforced soil structure were completely replaced by substitute building materials in the project. A demonstrator was set up on the university campus and its feasibility was tested by means of soil-mechanical and ecological investigations.
