Polyvinyl chloride (PVC) is among the world’s most widely used polymers. Recycling PVC via mechanical and high-temperature chemical processes is challenging due to its chlorine content.The startup company Plastic Back (Tel Aviv, Israel; www.plastic-back.com) aims to raise the rates of…
Understanding the forces acting on agitator impeller blades during turbulent flow in a mixing vessel is essential for successful and efficient operation. Presented here is information on the hydraulic force, its source, and how to calculate it Mechanically agitated vessels…
Electrically conductive plastics, also known as conjugated polymers, bring many cutting-edge benefits for flexible sensors, medical devices, energy-storage systems and more. They are currently produced at relatively small volumes and come with extremely high prices. A novel technology discovered at…
As the hydrogen economy matures and production scales up, critical equipment like valves must evolve to ensure safe and optimized handling and transport According to the Energy Transition Council, the overall share of fossil fuels is expected to decrease significantly…
Selecting the right technology to ensure accurate and reliable level measurement can help solve the unique challenges posed by storing and processing solid materials Advanced measurement solutions are helping to enhance process control, operational efficiency and safety throughout the chemical…
Drying can be defined as the vaporization and removal of liquids from a solution, suspension or other solid-liquid mixture to form a dry solid. Drying occurs as a result of the vaporization of liquid by supplying heat to wet solid…
AI, machine learning and predictive analytics encourage faster, data-driven decision making To help offset the loss of experienced operators and optimize operations, advanced features, such as artificial intelligence (AI), machine learning (ML) and predictive analytics, are being applied to software…
In October, the Royal Swedish Academy of Sciences awarded the 2025 Nobel Prize for chemistry to three pioneers who were instrumental in the development of metal-organic frameworks (MOFs). Richard Robson (University of Melbourne; www.unimelb.edu.au), Susumu Kitagawa (Kyoto University; www.kyoto-u.ac.jp and…
Processes to reuse plastics from end-of-life vehicles are complicated by solid contaminants — including pre-embedded metal and rubber components of different sizes and reinforcing glass fiber. Currently, recycling solids-containing waste-plastic parts is accomplished by physical sorting processes. Honda (Tokyo, Japan;…
Carbon-fiber reinforced plastics (CFRPs) are used in a broad range of products, including automotive parts, construction materials and many others. Economically recycling these materials has proven challenging due to their multi-material makeup. Typically, they are chopped into pellets or strips…
