WieBauIn: Innovative reuse of construction materials



WieBauIn: Innovative reuse of construction materials

Urban and rural areas are closely interlinked through the construction sector, as construction materials needed in urban areas are often produced in the vicinity of cities. Concurrently, waste from the urban construction sector is deposited in rural areas. This leads to the use of natural resources and land in rural areas without creating sustainable compensation.

Goal and Approach

WieBauIn aims to reduce the use of land and raw material resources in the construction sector by reusing components and recycling construction materials. Value chains, spanning from owners of buildings intended for demolition to users of the recovered components and materials, are developed in order to reduce environmental impacts and mutually increase value creation. A building and material cadaster will be set up, creating opportunities for rural and urban development through central development areas.

Expected Results and Transfer

Results from WieBauIn range from tools for addressing owners through the development of a building and material cadaster to a material flow model to reduce resource consumption. This is linked to transferable business models for the urban regional recycling economy. Training modules help architects, builders and craftsmen use recyclable components.
