The challenge: Construction projects require a huge amount of materials; they use and largely seal off whole areas of land, and produce considerable amounts of waste. Resource protection is therefore of particular importance to us. At inner-city sites, for example, HOCHTIEF endeavors to use derelict land and gaps between existing buildings or to refurbish older properties. Waste separation and recycling are standard practice worldwide, as is renaturation. Our Australian company Thiess, for example, is at pains to ensure that, once excavated, mines are partly filled and reforested.

Our objective: We aim to conserve natural resources and optimize the use of resources.
