A new recycling technology has been developed to turn used tires into raw materials for rubber and nylon, achieving high selectivity of up to 92% and a yield of 82%. The process uses dual catalysis to convert waste rubber into valuable chemicals.
Researchers at ETH Zurich developed a groundbreaking method to recycle Plexiglas by breaking down polymer chains into individual monomer building blocks. The process relies on a chlorinated solvent and UV light, with yields of up to 98% even in multicoloured samples.
Scientists at the University of Groningen have created a novel microwave-assisted chemical recycling process for aramid fibers, including Twaron and Kevlar. The new method achieves a high conversion rate of 96% in just 15 minutes, without using organic solvents.
Researchers at Princeton University have developed a method to recycle two of the planet's most challenging plastics using a common additive called carbon black. The process involves intense light focused on plastic containing the pigment, jumpstarting depolymerization and producing valuable commodity chemicals.
A novel method for the selective chemical recycling of PET has been developed, allowing for the recovery of polyester from textile waste. The method uses alcohols and an inexpensive iron trichloride catalyst to yield diethyl terephthalate and ethylene glycol with high selectivity.
Researchers at Shinshu University propose a new chemical process to depolymerize cyclic α-substituted styrene-based vinyl polymers, resulting in the recovery of monomer precursors. This efficient recycling system can facilitate effective resource circulation and development of new plastic recycling technologies.
Researchers developed a novel solid-state mechanochemical reaction to synthesize FCMs from PTFE and graphite, producing materials with enhanced storage capacity and electrochemical stability. The new method bypasses toxic reagents and offers a safer alternative for practical applications.
Recent development in identification of oligomeric products from lignin depolymerization reveals understanding of formation causes and potential valorization routes. Common targeted products include monomeric phenols, aromatics, and cycloalkanes.
Scientists discovered the molecular basis of CAMSAP3's role in stabilizing microtubules, which is critical for cell survival and various cellular processes. The findings provide a key concept to understanding how microtubule dynamics control cellular phenomena.
Researchers developed an enzyme that can break down plastic waste in hours, making it a promising solution for the world's plastic problem. The enzyme, called FAST-PETase, has the potential to revolutionize recycling and reduce global landfill waste by billions of tons.
Researchers have developed a polymer that self-destructs upon activation, using low-temperature stability to break apart quickly. The material has been used in a rigid-winged glider and nylon-like parachute fabric for airborne delivery, and its potential applications include environmental sensors and building materials.
A study published in Developmental Cell reveals that actin depolymerization, not myosin motor contraction, is the main force behind yeast cell division. The research uses a novel quantitative microscopy model to confirm this finding and sheds light on cytokinesis mechanisms.
