20.500.12556/RUL-156154 Composting of recovered rock wool from hydroponics for the production of soil amendment Due to its fibrous structure and high water holding capacity, rock mineral wool (RMW) has boosted the development of hydroponics. Consequently, the amount of waste RMW has also increased tremendously, which has stimulated the research and development of RMW reuse options. In this study, composting and degradability of RMW from hydroponics (gRMW) were tested in combination with different ratios of biowaste compost, including physical and chemical properties of the starting and final materials, and potential ecological hazards of the final product. gRMW had high water holding capacity and low organic matter content, which was easily degradable. Limits of toxic elements according to EU regulation were not exceeded. Degraded gRMW mixtures with compost did not exhibit toxicity to plants or aquatic bacteria and showed intermediate or limited habitat function for earthworms, which preferred the sole gRMW not mixed with compost. Overall, degraded gRMW exhibited parameters of safe soil amendment. recycling circular economy horticulture bioassay hexavalent chromium respirometer kamena volna hidroponika kompostiranje krožno gospodarstvo biološki preizkusi true false true Angleški jezik Slovenski jezik Članek v reviji 2024-05-10 16:37:40 2024-05-10 16:37:42 2024-05-11 03:58:07 0000-00-00 00:00:00 2024 0 0 Str. 29280-29293 iss. 20 Vol. 31 Apr. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 57 1614-7499 10.1007/s11356-024-33041-2 191675139 s11356-024-33041-2.pdf s11356-024-33041-2.pdf 1 429F6CE99FF8859E2CF462D6D834AE79 af03c630ed27be5300792efcc2a9110bda4756b9a81cf2bbebc78eed0c3f0dc7 2209ab04-0edb-11ef-99d3-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183458 https://link.springer.com/article/10.1007/s11356-024-33041-2 0 db10bed2-0eda-11ef-99d3-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183457 Zdravstvena fakulteta Fakulteta za gradbeništvo in geodezijo Biotehniška fakulteta 0 0 0
