Resource-efficient tunnelling: the new guideline of the Austrian Society For Construction Technology regarding the utilisation of tunnel excavation material.

Civil engineering contributes to the greenhouse potential by a third, holds a share of about 40% of the global energy demand and of more than 50% of the generated waste. Therefore, tunnel excavation material and its high-grade and preferably complete utilisation render a significant contribution to the development of a sustainable economic system by enhancement of efficiency and effectiveness. Discussion is presented of the Austrian legal framework for the utilisation of tunnelling waste, including waste management law, landfill ordinance, and remediation. Waste materials can be used in the production of concretes, mortar, road materials, as bulk material, or for backfilling, depending on its properties and grain size.
