• Process converts polyethylene bags, plastics to polymer building blocks
  

  Polyethylene plastics — in particular, the ubiquitous plastic bag that blights the landscape — are notoriously hard to recycle. They’re sturdy and difficult to break down, and if they’re recycled at all, they’re melted into a polymer stew useful mostly for decking and other low-value products. But a more

• Microplastic pollution in the Northeast Atlantic: First long-term record from deep water layers of the open ocean
  

  Scientists from the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) for the first time analysed a long-term sample series on microplastic pollution in the Northeast Atlantic from 2000 m water depth with respect to number, size, mass, material and possible origin of the particles. Samples more

• X-ray insights may enable better plastics production
  

  An X-ray study at DESY is pointing the way towards a better understanding of plastics production. A team led by Utrecht University investigated so-called Ziegler-type catalysts, the workhorses in the world's polyethylene and polypropylene production, at DESY's X-ray source PETRA III. As the scientis more

Soap That Slides Off the Bottle

You thought getting ketchup out of a bottle was hard? Ohio State University researchers have tackled an even harder problem: getting shampoo out of a bottle. The chemicals that make soap “soapy” also make them stick to plastic, but here a microscopic coating makes the soap just roll off. more

A Guide to Common Household Plastics

Plastic is everywhere in our day to day lives – but, of course, ‘plastic’ is just a catch-all term for a range of different chemical substances. This graphic takes a look at some of the more common plastics we encounter on a regular basis, and examines their chemical structures. Below, we’ll also ta more

The Chemistry of Paper and Polymer Banknotes

Last week the UK put its first polymer note into circulation, and it plans to replace all of its paper banknotes with polymer notes by 2020 (with the current exception of the £50 note). It’s far from the first country to introduce polymer notes, however; in fact, Australia has been using them since more
