#Eggshells from agro-industrial waste for the recovery of #lime, #portlandite, and #calcite nanoparticles through the lime cycle: A circular economic approach
Highlights:
• The study proposes to obtain calcite (#CaCO3) from eggshell agro-industrial waste within a circular economy approach.
• The lime cycle can be used to transform calcite (CaCO3) into lime (CaO) or portlandite (Ca(OH)2).
• Eggshells contain trace elements that can aid in synthesizing materials for #EnvironmentalRemediation.."Eggshells from agro-industrial waste can be used as natural source to obtain nanometric CaCO3, CaO, and Ca(OH)2 using the lime cycle. The nanometric size and the phase identification of all samples were confirmed by X-ray diffraction and FWHM. The SEM images show that CaCO3, CaO, and Ca(OH)2 from eggshells are microparticles in the form of nanocrystals, which correlate with the DLS results. The Zeta Potential varies due to the loss of CO2 when CaCO3 is converted in CaO, and for this reason, the CaO is more negative. When CaO is hydrated, the Ca(OH)2 is more stable, and these differences can be attributed to the mineral content in the samples. Eggshells naturally have different trace minerals that maintain a long calcium cycle and show variation due to a concentration effect when the CaCO3 changes to CaO. There is a notable a decrease of the trace minerals when CaO. When CaO is converted to Ca(OH)2, there is a significant decrease in trace minerals as some ions are soluble in the water during soaking. It is recommended to carry out the conversion of CaO to Ca(OH)2 under controlled conditions (low humidity and CO2). These findings can be useful to treat #AgroIndustrial waste and to develop nanotechnological applications in different fields."

🌎 Mapping dominant chemical speciation in a polluted carbonate aquifer
In my recent modeling work, I modeled the dominant forms of element speciation in groundwater within a carbonate system.
Beyond pure geochemical curiosity, this approach provides a practical lens:
– it reveals where mineral precipitation is most probable,
– and helps identify zones where remediation can be most effective.💻 Combining thermodynamic modeling (PHREEQC) with spatial analysis in R and QGIS turns subsurface processes into actionable insights for water-quality management and contamination mitigation.
Two figures below show the modeled distribution of cadmium species across the aquifer and their evolution with dilution

It is also interesting to see how people spend significant time and effort to download digital facsimiles from academic repositories, edit every image, and upload them to the Internet Archive.
See, for example, scans of البلاغ الاسبوعي published in Cairo from 1926 onwards ( https://www.wikidata.org/wiki/Q60578577 ). Scans of the copies held by the University of Tübingen are hosted by the University of Bonn: https://digitale-sammlungen.ulb.uni-bonn.de/ulbbnioa/periodical/pageview/7282062.

#Sweden - Removal of #PFAS from water by #AquaticPlants
Maria Greger, Tommy Landberg
February, 2024Highlights
• High total biomass is important plant trait for high PFAS accumulation from water.
• Higher PFAS accumulation in shoot than roots with time.
• Degradation of PFAS with root peroxidases and laccases.Abstract:
"We have found that aquatic plants can reduce the content of perfluorinated alkyl substances (PFAS) within a short period of time. The aim of this study was to determine the variation in the uptake of PFAS from contaminated water by various #wetland plant species, investigate the effect of #biomass on PFAS removal, and determine whether laccases and peroxidases are involved in the removal and degradation of PFAS. Seventeen emergent and one submerged wetland plant species were screened for PFAS uptake from highly contaminated lake water. The screening showed that #EriophorumAngustifolium, #CarexRostrata, and #ElodeaCanadensis accumulated the highest levels of all PFAS. These species were thereafter used to investigate the effect of biomass on PFAS removal from water and for the enzyme studies. The results showed that the greater the biomass per volume, the greater the PFAS removal effect. The plant-based removal of PFAS from water is mainly due to plant absorption, although degradation also occurs. In the beginning, most of the PFAS accumulated in the roots; over time, more was translocated to the shoots, resulting in a higher concentration in the shoots than in the roots. Most PFAS degradation occurred in the water; the metabolites were thereafter taken up by the plants and were accumulated in the roots and shoots. Both peroxidases and laccases were able to degrade PFAS. We conclude that wetland plants can be used for the purification of PFAS-contaminated water. For effective purification, a high biomass per volume of water is required."

#Australia: Research shows #NativePlants can detox #PFAS-contaminated #water
New research from Australia's national science agency #CSIRO, the #UniversityOfSouthAustralia and the #UniversityOfWesternAustralia has found that PFAS chemicals can be removed from contaminated water using Australian plants grown in a floating #wetland.
May 4, 2022
"They’re the non-stick on #Teflon cookware, the stain resistance in #Scotchgard, and the suppression factor in #FirefightingFoam, but while the staying power of PFAS chemicals was once revered, it’s now infamous as PFAS substances continue to infiltrate the #environment and affect human health.
"Now, new research from the University of South Australia is helping to remediate the ‘indestructible’ PFASs as scientists show that Australian native plants can significantly remediate PFAS pollutants through floating wetlands to create healthier environments for all.
"Conducted in partnership with CSIRO and the University of Western Australia, the research found that PFAS chemicals (per- and poly-fluoroalkyl substances) can be removed from contaminated water via Australian #NativeRushes - #PhragmitesAustralis, #BaumeaArticulata, and #JuncusKraussii.
"Phragmites australis, otherwise known as the #CommonReed, removed legacy PFAS contaminants by 42-53 per cent from contaminated surface water (level: 10 µg/L).
"According to the US Environmental Protection Agency, exposure to PFAS may lead to a range of health issues including a decline in fertility, developmental delays in children, increased risk of some cancers, a reduced immune system, higher cholesterol, and risk of obesity.
"UniSA and CSIRO researcher Dr John Awad says that this research could alleviate many of these environmental and health risks by providing a clean, green, and cost-effective method to remove PFAS from the environment.
" 'PFASs are often referred to as ‘forever chemicals’ because they don’t break down, instead accumulating in the environment and in our bodies where they can cause adverse health effects,' Dr Awad says.
" 'In Australia, PFAS concerns often relate to the use of firefighting foam – especially legacy firefighting foam – which accumulates in the #SurfaceWater of our #waterways.
" 'Our research tested the effectiveness of Australian rushes to remove #PFASChemicals from #stormwater, finding that Phragmites australis was the most effective at absorbing chemicals through its roots and shoots.'
"The study used constructed floating wetlands as a mechanism for plants to grow #hydroponically. Dr Awad says floating wetlands present a novel and flexible way for natural #remediation systems.
" 'Constructed floating wetlands can be readily installed into existing urban environments, such as holding reservoirs and retention basins, making them highly manoeuvrable and adaptable to local waterways,' Dr Awad says.
" 'Plus, as this innovative water treatment system does not require pumping or the ongoing addition of #chemicals, it is a #CostEffective remediation system for PFAS removal.
" 'Add native plants to the mix and we have delivered a truly clean, green and environmentally-friendly method for removing toxic PFAS chemicals from contaminated water.' "
Notes to editors:
- So far, the floating wetlands system has only been examined under control laboratory conditions for PFAS remediation and the research team is looking forward to testing it in the real world, under natural conditions.
- This research is being carried out at the UniSA Mawson Lakes campus. PFAS has not been detected in or around Mawson lakes."Original press release:
