The biosolids derived biochar demonstrated >80% adsorption of long-chain PFASs and 19-27% adsorption of short-chain PFASs from PFAS contaminated water.]]> Wed 10 Aug 2022 11:48:20 AEST ]]> Remediation of poly- and perfluoroalkyl substances (PFAS) contaminated soils - to mobilize or to immobilize or to degrade? https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39613 Wed 10 Aug 2022 11:41:40 AEST ]]> Assessment of the fertilizer potential of biochars produced from slow pyrolysis of biosolid and animal manures https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46172 –1, respectively), while the highest P was found in biosolid biochar (40.5 g kg–1). The specific surface area of biochars ranged from 96.06–110.83 m2 g–1. Hierarchical analyses of the chemical compositions of feedstocks and biochars enabled grouping of the materials respectively into four and five distinguished clusters. Three principal components (PC) explained 86.8% and 83.3% of the variances in the feedstocks and biochars, respectively. The PC1 represented the content of the major nutrients (N, P and K), whereas PC2 and PC3 represented other nutrients (secondary and micronutrients) contents and physicochemical properties (pH and EC). The results of this study suggested that biochars produced from different manures and biosolids may potentially be a source of soil nutrients and trace elements. In addition, different biochars may be applied to different nutrient-deficient soils to avoid plausible nutrient and potentially toxic element contamination.]]> Wed 07 Feb 2024 14:49:22 AEDT ]]> A critical literature review on biosolids to biochar: an alternative biosolids management option https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38079 Tue 03 Aug 2021 15:12:30 AEST ]]> The impact of biosolids application on organic carbon and carbon dioxide fluxes in soil https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31956 −1 biosolids. Soil samples were analyzed for SOC fractions, including total organic carbon (TOC), labile, and non-labile carbon contents. The natural abundances of soil δ13C and δ15N were measured as isotopic tracers to fingerprint carbon derived from biosolids. An automated soil respirometer was used to measure in-situ diurnal CO2 fluxes, soil moisture, and temperature. Application of biosolids increased the surface (0–15 cm) soil TOC by > 45% at both sites, which was attributed to the direct contribution from residual carbon in the biosolids and also from the increased biomass production. At both sites application of biosolids increased the non-labile carbon fraction that is stable against microbial decomposition, which indicated the soil carbon sequestration potential of biosolids. Soils amended with biosolids showed depleted δ13C, and enriched δ15N indicating the accumulation of biosolids residual carbon in soils. The in-situ respirometer data demonstrated enhanced CO2 fluxes at the sites treated with biosolids, indicating limited carbon sequestration potential. However, addition of biosolids on both the clay loam and sandy loam soils found to be effective in building SOC than reducing it. Soil temperature and CO2 fluxes, indicating that temperature was more important for microbial degradation of carbon in biosolids than soil moisture.]]> Thu 21 Oct 2021 12:52:20 AEDT ]]> A study on carbon storage in soil using biosolids https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33451 Thu 12 Sep 2019 09:29:00 AEST ]]> Distribution, behaviour, bioavailability and remediation of poly- and per-fluoroalkyl substances (PFAS) in solid biowastes and biowaste-treated soil https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38586 Thu 11 Nov 2021 13:58:36 AEDT ]]> Utilization of biowaste for mine spoil rehabilitation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30338 Sat 24 Mar 2018 07:31:47 AEDT ]]> Identifying and ameliorating nutrient limitations to reconstructing a forest ecosystem on mined land https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24087 Corymbia maculata. The higher rate of fertilizer addition improved seedling establishment of Mimosaceae and the survival of Myrtaceae species. High nutrient treatments increased weed and grass densities, which may have reduced the nutrient benefit for native species. In conclusion, biosolids and the high rate of fertilizer application ameliorated the nitrogen and phosphorus deficiency of spoil to support growth and survival of reintroduced native species. However, potential benefits were attenuated by competition from accompanying weed growth that could be managed by implementing a control program.]]> Sat 24 Mar 2018 07:11:47 AEDT ]]> Uptake, accumulation, and toxicity of per- and polyfluoroalkyl substances in Allium cepa grown in soils amended with biosolids https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50286 Fri 14 Jul 2023 09:21:20 AEST ]]>
