1. Background The demand for raw materials continues to grow unabated, and efforts to decouple economic performance from resource consumption have so far been largely unsuccessful. According to estimates, global raw material consumption will at least double over the next 30 years (1). The construction sector plays a very important role in terms of efficient […]

Introduction At the end of the 1980s, a new landfill site was needed in the district of Bad Kissingen, as the Arnshausen landfill site that had been in operation until then was almost completely filled. A quarry in the immediate vicinity of the old landfill site, where shell limestone had been mined for gravel since
Introduction Tailings dams are mining waste dumps where the products of mineral extraction are deposited. These residues consist of fine-grained material and are usually deposited hydraulically. In principle, these processing residues can be generated in the energy sector (e.g. ash) or in the mineral extraction industry (gold). Neglected for decades, the industry's attitude towards tailings

Abstract In surface-parallel layered systems, such as surface sealing of landfills, geogrids are used to make these systems steeper. The geogrids absorb high tensile forces, which are anchored at the crest of the embankment in so-called anchor trenches. The previous design approach of EBGEO (2010) contains a number of assumptions that must be considered overly

GEG Limited Liability Company Landfill I: The oldest section of what later became the "Halle-Künsebeck Central Landfill" was filled with domestic and commercial waste from 1966 to 1982. The Halle-Künsebeck I and II landfills are located in quarried limestone pits on the southern ridge of the Teutoburg Forest. To the north, east and west, the
