In the field of environmental engineering, the professional handling of mineral waste is becoming increasingly important - especially when asbestos is involved. Regulatory specifications, technical limits and occupational health and safety requirements place high demands on planning, dismantling and disposal.<\/p>\n\n\n\n
Against this background, this article deals with the Recycling ban for mineral waste with intentionally added asbestos<\/strong>. The categorisation is carried out from an environmental and legal perspective and is particularly relevant for infrastructure, transport and civil engineering structures. The technical classification takes place, among other things, in the context of the environmental expertise of BIG - Member of the SIERA Alliance<\/strong>.<\/p>\n\n\n\n The highly stressed road surface layers in particular often incorporate basic, magmatic rocks such as basalt, diabase or gabbro, which can contain natural proportions of asbestos minerals. In the 1960s and 1970s in particular, asbestos fibres were also intentionally added (e.g. in joint sealants for concrete road surfaces or as asbestos-containing spacers in bridge structures).<\/p>\n\n\n\n According to Section 3 (1) of the Chemicals Prohibition Ordinance (ChemVerbotsV) in conjunction with Annex XVII of Regulation (EC) No. 1907\/2006 (REACH Regulation), the manufacture, placing on the market and use of asbestos fibres and of articles and mixtures to which these fibres are intentionally added is prohibited. This ban does not apply to naturally occurring mineral raw materials and preparations and articles made from them that contain asbestos with a mass content < 0.1 %.<\/p>\n\n\n\n According to Section 16 (2) in conjunction with Annex 2 No. 1 (asbestos) of the Hazardous Substances Ordinance, the extraction, processing, further processing and reuse of naturally occurring mineral raw materials and preparations and products made from them that contain asbestos is only prohibited with a mass content of 0.1 % or more.<\/p>\n\n\n\n According to the specifications of TRGS 517, layers with a proportion of respirable asbestos fibres according to WHO < 0.008 M.-% must be declared \u201easbestos-free\u201c. \u201eSpecial measures\u201c for occupational health and safety are not required. With an asbestos content WHO \u2265 0.008 M.-%, the layers must be declared as \u201easbestos-containing\u201c, but are classified as \u201enon-hazardous waste\u201c up to the limit of 0.1 M-%.<\/p>\n\n\n\n According to the Hazardous Substances Ordinance, mixtures and products with an asbestos content of less than 0.1 M.-% may be reused. Irrespective of this, \u201especial measures\u201c for occupational health and safety are required for the removal of layers containing asbestos.<\/p>\n\n\n\n From a mass content of \u2265 0.1 M.-%, it is waste that may no longer be placed on the market and must be disposed of as hazardous waste.<\/p>\n\n\n\n Please note when specifying the results: Values are not rounded, i.e. a result of e.g. 0.099 M.-% is not rounded up to 0.1 M.-%. This means that the value is below the value of 0.1 M.-% and is therefore categorised as \u201enon-hazardous waste\u201c.<\/p>\n\n\n\n There are no exemptions from restriction regulations for intentionally added asbestos. As soon as asbestos is detected, it must be removed from the circular economy in accordance with the ChemVerbV in conjunction with the REACH Regulation, regardless of its mass content.<\/p>\n\n\n\n If it turns out that asbestos products have been used, it must be checked with regard to the KrWG whether these products can be separated from the rest of the building. If this is not the case, a mass analysis is required, i.e. the mass of asbestos must be converted to the mass of the building.<\/p>\n\n\n\n \u27a2 If the mass fraction is less than 0.1 M.-%, the demolition waste must be disposed of as non-hazardous waste with the waste code 17 01 01 concrete with the addition \u201econtains asbestos\u201c at a landfill authorised for this purpose.<\/p>\n\n\n\n With a mass fraction of \u2265 0.1 M.-%, the demolition material must be disposed of as hazardous waste with the waste code 17 06 05* Asbestos-containing building materials at a landfill authorised for this purpose.<\/p>\n\n\n\n It is not permissible to extrapolate the asbestos content to the total demolition material in order to make the declaration \u201easbestos-free\u201c. If spacers containing asbestos are present, the entire demolition material must be categorised as \u201econtaining asbestos\u201c.<\/p>\n\n\n\n For engineering and environmental projects - especially in transport and infrastructure construction - the Correct classification of asbestos content<\/strong> crucial for planning security, occupational safety and legally compliant disposal.
