Toxic Tire Decontamination: Researchers Demonstrate Ability to Remove Toxic Particles from Used Tires
Evolution of heating performance, product distribution, and morphology in microwave pyrolysis of EOL tires. Credit: Nature Chemical Engineering (2024). DOI: 10.1038/s44286-024-00110-9 Tires are an essential part of daily life. Without these, our vehicles would simply be a mass of assembled parts, convenient to sit on but ineffective at getting us to our destination. While the usefulness of tires is undisputed,…

Innovative method aims to remove PFAS from wastewater
Credit: Pixabay/CC0 Public Domain Researchers at Oxford Brookes University have developed an innovative way to tackle one of the world’s most persistent environmental threats: toxic chemicals in the world’s water supplies. They developed a new machine called a hydrodynamic reactor that uses gas bubbles that form and collapse due to changes in pressure, a process called cavitation. This reactor removes…

DOI: 10.1002/app.55428 While water filters currently on the market can remove some contaminants, they are not designed to capture microplastics. In fact, some water filters can even introduce tiny plastic particles into your drinking water during the filtration process. Even…
