20.500.12556/RUL-131847 Recycling of nonwoven polyethylene terephthalate textile into thermal and acoustic insulation for more sustainable buildings The construction and building sector is responsible for a large share of energy and material used during the life cycle of a building. It is therefore crucial to apply a circular economy model within the process wherever possible to minimize the impact on the environment. In this paper, the possibility of producing thermal and acoustic boards from industrial nonwoven waste textile is studied and presented. The nonwoven polyester textile obtained directly from the production line in the form of strips and bales was first shredded into smaller fractions and then in the form of pile compressed with a hot press to form compact thermal insulation boards. The first set of specimens was prepared only from waste polyester nonwoven textile, whereas the second set was treated with sodium silicate in order to check the material’s reaction to fire performance. The experimental work was conducted to define the acoustic properties, reaction to fire behavior and thermal conductivity of the produced specimens. The obtained results show that the thermal conductivity coefficient of specimens without added water glass dissolution is near to the values of conventional materials used as thermal insulation in buildings. The reaction to fire testing proved that the addition of water glass actually propagates the progressive flame over the entire product. It can be concluded that the presented thermal insulation can be used as an adequate and sustainable solution for building construction purposes. textile waste thermal insulation sound absorber sustainability circular economy recycling tekstilni odpadki toplotna izolacija zvočna izolacija trajnostnost krožno gospodarstvo reciklaža true false true Angleški jezik Slovenski jezik Članek v reviji 2021-10-04 13:32:52 2021-10-04 13:32:53 2023-05-17 03:56:54 0000-00-00 00:00:00 2021 0 0 15 str. iss. 18, art. 3090 Vol. 13 Sep. 2021 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 699.8 2073-4360 10.3390/polym13183090 76471811 polymers-13-03090-v2.pdf polymers-13-03090-v2.pdf 1 E3285F822FF78AE3C2A93C0C9A5D4FDF 07fdb68ace2de5cf31cc4ab729ab330cbbf621e4c5aaedb45f1146e0a030135b 97b5f813-f3d8-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=168876 https://www.mdpi.com/2073-4360/13/18/3090 1 85a6e53d-2506-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149262 Fakulteta za gradbeništvo in geodezijo 0 0 0
