A paper on the recovery of silver from Midsummer's CIGS solar cells has been published in Science Direct. It shows a complete recovery of Ag and ITO particles from a flexible CIGS solar cell with a stainless steel substrate, with purities equal to 95.0 and 70.5 wt%, respectively. Midsummers' solar cells continue to be the probably most recyclable in the world.

As the demand for lithium-ion batteries strains resources, Flinders University researchers are pioneering Aqueous Zinc-Ion Batteries (AZIBs) as a low-cost, eco-friendly alternative. With zinc being abundant and safe, AZIBs could revolutionize energy storage for everything from electric vehicles to portable devices. Their innovative work on organic cathodes and affordable production methods promises a greener future for battery technology. #energystorage #battery #climate #energy #sustainability

Exciting news! Heriot-Watt University scientists have developed a breakthrough nanoparticle that enables #electrolysis to perform using #wastewater AND produced similar/slightly higher quantities of green hydrogen compared to fresh water! To make 1kg of #greenhydrogen, we need 9kg of water and #whiskydistilleries in Scotland produce c.1 million litres of wastewater a year from the distilling process. Using waste instead of natural ressources is the best way to meet our #net_zero_ambitions. https://lnkd.in/exwhGHe6

New decapsulation tech for solar module recycling: The Chinese Academy of Science has developed a new technique that uses non-toxic lemonene as a reagent to control the degree of EVA expansion during the decapsulation process of end-of-life photovoltaic modules. The proposed approach reportedly achieves the complete delamination of glass and backsheet without excessive damage to the solar cells #ModulesUpstreamManufacturing #TechnologyandRD #photovoltaic

In our latest collaborative work, involving Friedrich Schiller University Jena and Università degli Studi di Napoli Federico II, we introduce a novel electrolyte for lithium-ion batteries comprising LiTFSI salt dissolved in bio-based 𝜸-valerolactone (GVL). Moreover, we proposed a simple and sustainable aqueous-based recycling approach for recovering the imide-based lithium salt. We showed that this simple recycling method allows for a nearly complete recovery of the LiTFSI salt and the GVL solvent. The feasibility of the recycling process is validated by the reutilization of the recovered LiTFSI salt in electric double-layer capacitors, achieving performances similar to that of the pristine salt with exceptional long-term stability.   Thanks to Khai Shin Teoh, Massimo Melchiorre, Sandesh Darlami Magar, Christian Leibing, Francesco Ruffo and Juan Luis Gómez Urbano for the great work! #lithiumionbatteries #electrolyte #sustainability

I'm thrilled to share my latest scientific publication, now available in the AIP Conference Proceedings! 🚀🔬 In this study, we conducted a comprehensive literature review to explore the challenges and innovative solutions for recycling electric vehicle lithium-ion batteries. With a significant volume of these batteries expected to reach their end-of-life stage, efficient recycling processes are crucial. Our research focused on supercritical fluid extraction (SCFE) using CO2 to recover strategic metals like Li, Co, Mn, and Ni with a high efficiency. This sustainable method not only addresses the limitations of mainstream recycling technologies but also utilizes CO2 captured from the steel industry, advancing both resource preservation and the global energy transition.

Your guidance and collaboration were invaluable. 🙏 #Research #MetallurgicalEngineering #LithiumIonBatteries #Innovation #ScientificPublication #EngineeringExcellence #Sustainability #EnergyTransition

🌱🔋 I’m thrilled to share our new research paper, "Life Cycle Assessment of Bio-Based Hard Carbon for Sodium-Ion Batteries Across Different Production Scales." This work is a significant part of my PhD research, and I‘ve been eagerly anticipating this moment to share our findings with you all. The study dives deep into the environmental impacts of hard carbon production, crucial for advancing sodium-ion batteries as a sustainable and cost-effective alternative to lithium-ion batteries. Our findings highlight the importance of energy use and emissions, particularly from the pyrolysis process, and demonstrate how upscaling production can significantly improve sustainability. However, it also brings new challenges that need addressing…… find more in the Full Paper! 📖 https://lnkd.in/e3pbAZqb Special thanks to my supervisors Niklas von der Assen and Marcel Weil for their invaluable guidance and support throughout this work and my whole PhD.

🌟The Power of Synergy: Dark Fermentation and Microbial Electrolysis Igniting Sustainable Energy! 🌟 Dark fermentation, a promising biohydrogen production method, teams up with MECs to enhance efficiency and sustainability in hydrogen generation. This dynamic duo utilizes organic waste as a renewable resource, converting it into valuable hydrogen fuel through a two-step process. 🌱 Dark Fermentation: Microorganisms break down organic matter in an anaerobic environment, yielding hydrogen and volatile fatty acids (VFAs) as byproducts. ⚡ Microbial Electrolysis Cells (MECs): Harnessing the power of microbial communities, MECs employ electrochemical reactions to process VFAs, producing additional hydrogen and other valuable products. 🔄 Synergistic Benefits: By integrating these processes, we achieve remarkable advantages: 1️⃣ Enhanced Yield: Dark fermentation followed by MECs maximizes hydrogen production, optimizing resource utilization. 2️⃣ Waste Valorization: Organic waste becomes a valuable feedstock, reducing environmental impact and promoting circular economy principles. 3️⃣ Renewable Energy: Hydrogen generated through this synergy serves as a clean, sustainable alternative to fossil fuels, driving towards a greener future. 🌍 As we navigate towards a carbon-neutral tomorrow, collaborations like this exemplify the innovation and commitment needed to address global energy challenges. Join us in celebrating this remarkable advancement towards a more sustainable world! 🌿💡 #ISESLab #SustainableEnergy #HydrogenProduction #Innovation #RenewableFuture #CleanEnergy #DarkFermentation #MECs #GreenTechnology

Happy to announce the publication of our latest research in Academia Green Energy Journal. Our study, titled “Use of Building Wastes and Red Mud as CO2 Sorbent and Catalyst for the Production of Hydrogen”, that was conducted by Prof. Despina Vamvuka, Agapi Orfanoudaki and myself through our undergraduate studies, addresses the dual challenges of waste management and sustainable energy production within the framework of a low-carbon and circular economy. We have developed a method for producing hydrogen-rich biofuels by utilizing waste materials, including forest and agricultural residues, demolition waste from construction, and red mud (RM) from the aluminum industry as a novel CO2 sorbent and catalyst. This research highlights the potential for using industrial and construction waste materials as valuable resources for sustainable hydrogen production.
