Every year, millions of windshields are replaced worldwide, leaving behind a significant amount of waste in the form of the polyvinyl butyral (PVB) interlayer, which keeps shattered glass together. Recycling this material is complex and costly, often resulting in low-quality materials unsuitable for reuse. The sheer volume of PVB waste is substantial — over 175…

Lithium-sulfur (Li-S) batteries, often seen as a promising alternative to lithium-ion (Li-ion) technology, could offer higher energy densities and lower costs while using Earth-abundant materials like sulfur. However, significant hurdles, including short cycle life, material instability, and safety concerns, limit their commercial adoption. Potential and challenges of Li-S batteries Li-S batteries differ from Li-ion batteries…

Some argue that carbon capture, utilization, and storage (CCUS) are critical tools for reducing global carbon emissions, though questions remain about their scalability, cost-effectiveness, and long-term impact. Safe and efficient supercritical or dense-phase carbon dioxide (CO₂) transportation is critical for successfully implementing CCUS projects. According to the U.S. Department of Energy website, “Carbon capture, utilization,…

According to a recent study by U.S. and Canadian scientists, the carbon in our bodies may have traveled far beyond our galaxy before becoming part of Earth. Published in the Astrophysical Journal Letters, the research confirms that carbon and other elements forged in stars do not remain stationary in space but circulate through a vast…

Recent scientific evidence has brought increasing attention to microplastics—plastic particles less than 5 millimeters in diameter—and their pervasive presence in our environment. While their ubiquity raises legitimate concerns, our 2024 analysis “Microplastics are bad—but ignoring science is worse” reveals that commonly cited statistics about human plastic consumption often lack rigorous scientific validation. Emerging research continues…
