  • Using recycled material from the paper industry as a backfill material for retaining walls near railway lines [Elektronski vir]
    Fifer Bizjak, Karmen ; Likar, Barbara, gradbenica, 1985- ; Lenart, Stanislav
    The construction industry uses a large amount of natural virgin material for differentgeotechnical structures. In Europe alone, 11 million tonnes of solid waste is generated per year asa result of ... the production of almost 100 million tonnes of paper. The objective of this research is todevelop a new geotechnical composite from residues of the deinking paper industry and to present itspractical application, e.g., as a backfill material behind a retaining structure. After different mixtureswere tested in a laboratory, the technology was validated by building a pilot retaining wall structurein a landslide region near a railway line. It was confirmed that a composite with 30% deinking sludgeand 70% deinking sludge ash had a high enough strength but experienced some deformations beforefailure. Special attention was paid to the impact of transport, which, due to the time lag betweenthe mixing and installation of the composite, significantly reduced its strength. The pilot retainingwall structure promotes the use of recycled materials with a sustainable design, while adhering togovernment-mandated measures.
