Carbon recycling instead of plastic trash

Iron electrocatalysis breaks down polystyrene and delivers green hydrogen

14-Nov-2024 - Plastics are inescapable in our daily lives. The vast amounts of plastic garbage heaped in landfills and in the environment, however, are as problematic as the plastics are useful. In the journal Angewandte Chemie, a German research team has now introduced a new method for recycling polystyrene ...

How much microplastic are you drinking?

New tool can tell you in minutes

29-Aug-2024 - Micro- and nanoplastics are in our food, water and the air we breathe. They are showing up in our bodies, from testicles to brain matter. Now, University of British Columbiaresearchers have developed a low-cost, portable tool to accurately measure plastic released from everyday sources like ...

Scientists achieve more than 98% efficiency removing nanoplastics from water

The liquid-based solution uses a solvent to trap the plastic particles, leaving clean water behind.

20-Aug-2024 - University of Missouri scientists are battling against an emerging enemy of human health: nanoplastics. Much smaller in size than the diameter of an average human hair, nanoplastics are invisible to the naked eye. Linked to cardiovascular and respiratory diseases in people, nanoplastics continue ...

New polystyrene recycling process could be world’s first to be both economical and energy-efficient

Chemical method identified to tackle hard-to-recycle packaging material, cutting landfill waste

24-May-2024 - Engineers have modelled a new way to recycle polystyrene that could become the first viable way of making the material reusable. The team of chemical engineers, based at the University of Bath in the UK and Worcester Polytechnic Institute in Massachusetts, US, say their technique could be the ...

How to make ubiquitous plastics biodegradable

Understanding the function of a specific bacterial enzyme has paved the way for the biotechnological degradation of styrene

22-May-2024 - Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process. The ...

Plastic Recycling with a Protein Anchor

Peptide with a cobalt complex oxidizes polystyrene microparticles

22-Feb-2024 - Polystyrene is a widespread plastic that is essentially not recyclable when mixed with other materials and is not biodegradable. In the journal Angewandte Chemie, a German research team has introduced a biohybrid catalyst that oxidizes polystyrene microparticles to facilitate their subsequent ...

Scientists develop artificial ‘worm gut’ to break down plastics

Hopes for a nature-inspired way to tackle global plastic pollution

13-Feb-2024 - By feeding worms with plastics and cultivating microbes found in their guts, researchers from NTU’s School of Civil and Environmental Engineering (CEE) and Singapore Centre for Environmental Life Sciences Engineering (SCELSE) have demonstrated a new method to accelerate plastic ...

Bottled water can contain hundreds of thousands of previously uncounted tiny plastic bits

A new microscopic technique zeroes in on the poorly explored world of nanoplastics, which can pass into blood, cells and your brain

11-Jan-2024 - In recent years, there has been rising concern that tiny particles known as microplastics are showing up basically everywhere on Earth, from polar ice to soil, drinking water and food. Formed when plastics break down into progressively smaller bits, these particles are being consumed by humans ...

Not so silver lining: Microplastics found in clouds could affect the weather

Low-altitude and denser clouds contained greater amounts of microplastics

23-Nov-2023 - From the depths of the seas to snow on mountains and even the air above cities, microplastics are turning up increasingly often. Now, in ACS’ Environmental Science & Technology Letters, researchers have analyzed microplastics in clouds above mountains. They suggest that these tiny particles could ...

Polystyrene Upcycling

Recovering Valuable Chemical Building Blocks from Polystyrene Waste

31-Jul-2023 - Polystyrene, the main material in plastic tableware and insulating materials, is a widely used polymer but is currently difficult to recycle. Reporting in the journal Angewandte Chemie, a team of US researchers have now developed a thermochemical approach, making it possible to recover valuable ...
