ABSTRACT
According to United Nations projections there will be nine billion people living on Earth in 2050. This is closely linked with consumer market growth, increase in consumption of raw materials and also increasing environmental pollution. Thus, it is apparent that global industry and business activities must assume responsibility and find new paths. In the tunnel industry this has started already in designs for upgrading or constructing new infrastructure systems. Our common goal should be to bring re-use and eco-efficiency to our industry to minimise our carbon footprint by reducing the demand for new raw materials. This paper describes the reuse of valuable TBM components in order to save valuable resources in the form of material and energy whilst giving individual TBM components, assemblies or complete TBMs a completely new life cycle.
