New filter captures and recycles aluminum from manufacturing waste MIT engineers designed a nanofiltration process that could make aluminum production more efficient while reducing hazardous waste. MIT News https://lnkd.in/ep62Jf3J

Advances in material innovation is reshaping industries, fostering cleaner production methodologies, extending lifecycle and opening uncharted horizons in mobility, health care, electronics and renewable energy. FRP is one such material whose versatility, high strength-to-weight ratio, corrosion resistance, and design flexibility make it valuable across a gamut of sectors from aviation to healthcare. However, the major challenge lies with the recyclability. Chemical structure of thermosets, fiber degradation, unavailability of recycling infrastructure, economic viability are few recyclability concerns. Reducing the environmental impact of these composites requires a combined step of material innovation, recycling technique, and systematic changes in manufacturing and waste management. #Materialinnovation #FRP #Recyclability #Wastemanagement

MIT engineers have developed a new nanofiltration process to curb hazardous waste generated from aluminum production. The study, authored by Professor John Leinhard, undergraduates Trent Lee and Vinn Nguyen, and Zi Hao Foo SM ’21, PhD ’24, shows nanofiltration could be used to capture waste aluminum ions, which can then be upcycled and added to the bulk of the produced aluminum, increasing yield while reducing waste. https://lnkd.in/gG43DkSk

A #Lithium Ion #Battery consists of more than the electrodes... What about the cell casing? The latest paper by Malena Staudacher, Tony Lyon and Urs Alexander Peuker is dedicated to the processing and #recycling of the battery casing. It discusses common #sorting processes and the influence of selective deformation on the composite material. This research is embedded in the German federal activities in battery recycling greenBattNutzung - Recycling & Green Battery and Battery Utilisation Concepts and EIT RawMaterials RIS Hub Adria #AutoBatRec.

Recycling Lithium-Ion Batteries: Pre-Treatment Process The recycling of lithium-ion batteries involves a comprehensive pre-treatment process to safely and effectively recover valuable materials. Here’s a step-by-step explanation of the process: ➡ Spent Li-Ion Battery: The process begins with collecting spent or used lithium-ion batteries that are no longer suitable for use. ➡ Discharging: The collected batteries are fully discharged to prevent any risk of short circuits or explosions during subsequent handling and processing. ➡ Battery Disassembling: After discharging, the batteries are carefully disassembled. This step involves separating the different components, such as the casing, electrodes, and electrolyte. ➡ Carbon Reduction: The disassembled battery components undergo carbon reduction. In this step, the materials are processed to remove carbon components and other impurities, preparing them for further treatment. ➡ Mechanical Crushing: The solid residues from carbon reduction are then mechanically crushed. Crushing helps to reduce the size of the material, making it easier to handle and process in the subsequent steps. ➡ Sieving: The crushed material is sieved to separate particles based on size. This step ensures that fine particles, which contain valuable electrode materials, are collected separately from larger, less valuable pieces. ➡ Electrode Material: The fine particles collected from sieving, which contain the electrode materials such as lithium, cobalt, nickel, and manganese, are then further processed. These materials are essential for manufacturing new batteries and other applications. By following these steps, the recycling pre-treatment process efficiently recovers valuable materials from spent lithium-ion batteries, contributing to resource conservation and environmental protection. #BatteryRecycling #SustainableRecycling #LithiumIonRecovery #EcoFriendlyTech #ResourceConservation #EnvironmentalProtection #AltairEnergy

Stewart Mitchell recently wrote about scalable Type V hydrogen tank fabrication and CFRP lifecycle management (link in comments). In that article, he describes Cygnet Texkimp's composite recycling system. Let's zoom in on what that entails... ♻️ End-of-Life Recycling: Cygnet Texkimp's system reclaims valuable fiber from resin matrices without burning, chopping, or weakening. 🚯 The DEECOM Process: Utilizing B&M Longworth Ltd’s patented DEECOM pressolysis, the system reclaims waste from thermoplastic and thermoset polymers. ♨️ Supercritical Steam: The DEECOM process employs supercritical steam and compression swings to fracture polymer contaminants, operating at extreme temperatures up to 600°C and pressures up to 15 bar. ⛓️💥 Efficient Resin Dissociation: During the process, pressure and steam cause resin dissociation, forming vapor that is condensed into a water/resin solution, leaving behind high-performance dry fibers. ✈️ Versatile Fiber Extraction: Cygnet Texkimp’s system extracts resin from diverse fiber-reinforced polymers, including lightweight products and thick aerospace parts, across various composite components. 👇 Stewart's full article is linked in the comments below 👇

Valuable metals can be recycled from electronic waste more efficiently and with reduced environmental impact thanks to a recycling method developed by researchers in Texas. The team was led by Rice University’s James Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering. Their findings are detailed in Nature Chemical Engineering. The new technique enhances the recovery of critical metals and builds on Tour’s earlier work in waste disposal using flash Joule heating (FJH). This process involves passing an electric current through a material to rapidly heat it to extremely high temperatures, transforming it into different substances.

The market for durable plastics is growing as they cater to the needs of modern society, offering strength and performance at high temperatures. An example is crosslinked polyethylene (PEX), used in demanding applications like water pipes and roofing films. The enhanced durability stems from their stable and interconnected chemical structure. However, this very structure poses challenges for #recycling through traditional methods. Not anymore! We tested our unique #chemicalrecycling technology, Hydrochemolytic™ Technology (HCT), on PEX samples and achieved results similar to those for conventional PE. The 85+% yield of lower molecular weight hydrocarbons, primarily in the C8-C28 range, further establishes our capability to recycle complex polymers into valuable hydrocarbons.
