Engineers develop all-in-one solution to catch and destroy 'forever chemicals'

Chemical engineers at the University of British Columbia have developed a new treatment that traps and treats PFAS substances—widely known as "forever chemicals"—in a single, integrated system. The research appears in Nature Communications Engineering. Per- and polyfluoroalkyl substances (PFAS) are widely used in manufacturing consumer goods like waterproof clothing due to their resistance to heat, water and stains. However, they are also pollutants, often ending up in surface and groundwater worldwide, where they have been linked to cancer, liver damage and other health issues. "PFAS are notoriously difficult to break down, whether they're in the environment or in the human body," explained lead researcher Dr. Johan Foster, an associate professor of chemical and biological engineering in the faculty of applied science. "Our system will make it possible to remove and destroy these substances in the water supply before they can harm our health."

4A Molecular Sieve: High-Performance Desiccant

Molecular Sieve 4A Desiccants are high-performance drying agents designed to effectively remove moisture from various applications. With a pore size of 4 angstroms, these desiccants selectively adsorb water molecules while allowing larger molecules to pass through, ensuring optimal performance in gas and liquid separation processes. Ideal for use in pharmaceuticals, food packaging, and industrial applications, they enhance product stability and shelf life by maintaining low humidity levels. Their reusability and high adsorption capacity make them a cost-effective solution for moisture control.

Activated Carbon: Addressing Challenges and Opportunities in the Global Market

The global activated carbon market size is expected to reach USD 4.80 billion by 2030 to expand at a CAGR of 3.7% from 2024 to 2030 according to a new report by Grand View Research, Inc.  This increase can be attributed by the need for a powdered and granular form is expected to increase as the demand for water and air purification in coal-fired plants grows and clinker cement industries. Asia Pacific dominated the regional segment due to the growing industrialization in Japan and the developing economies. North America is another key region contributing to market growth due to stringent emission regulations in the region.

Activated Carbon Market Report Highlights

Powdered activated carbon segment dominated the type segment as they are used in water treatment which is the major end use industry of the market

Asia Pacific witnessed the fastest growth rate due to factors like large availability of good quality coconut shell. The regional market is also driven by growing disposable income, surge in the automotive industry

Companies such as Cabot Corporation have fully integrated their processes. Raw material procuring, product preparation and distribution processes are fully integrated. The full integration strategy adopted by companies is done to offset the volatility involved in raw material procurement and to implement strict quality parameters on production

The spread of COVID-19 has negatively impacted each and every sector including chemical. The supply chain of raw materials of silicone-based adhesion market drastically impacted the production and consumption pattern

Various regulatory agencies have enacted strict environmental pollution control policies and encouraged the use in air and water treatment plants, which is expected to boost the market throughout the anticipated period. Implementation of regulations by various governments is expected to drive the product consumption in the forecast period.

The supply chain of the raw materials was drastically impacted by the COVID-19 outbreak, which further affected the production and consumption patterns globally. Powdered carbon type has dominated the product consumption since last decade. Consequently, halt in production of non-essential chemicals, ingredients or industrial products has drastically hampered demand. This resulted in negative impact on the market in 2020.

Discarded silk yarn can clean up polluted waterways—researchers develop hollow sphere silk particles to test adsorption

Cornell researchers have developed an elegant and sustainable way to clean up waterways: reusing one waste product to remove another. Led by Larissa Shepherd, assistant professor in the Department of Human Centered Design, in the College of Human Ecology, the team has proposed using discarded silk yarn for the removal of dye and oil from water. Studies on several different forms of silk: fabrics, yarns, and fibers revealed that yarn unraveled from silk fabric, soaked up methylene blue (MB), a common textile dye, from water at a substantially higher rate than other forms of silk they tested. What's more, the silk yarn can be cleaned and reused. Shepherd's group found that the textile can withstand at least 10 cycles, with minimal loss of functionality.

For this type of chemical reaction, the equilibrium may lie far to the right and, while adsorption is favoured under particular pH conditions, it is not simply dependent on whether there is a positive or negative charge on the surface of the solid.
