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
A significant part of carpet waste consists of petroleum-based polypropylene. As a non-recyclable product, disposing of it has previously meant incineration or landfill. However, a new solvent is now making it possible to recover virgin-standard polypropylene from carpet waste — with no perceptible more
Polypropylene (PP) is one of the most widely used plastics in the world. By controlling the spatial orientation of the propylene building blocks and additional polar components, it should be possible to create a new generation of attractive, engineered, specialty plastics, with improved wettability more
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
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
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
