Chemists are reimagining recycling to keep plastics out of landfills

It feels good to recycle. There’s a certain sense of accomplishment that comes from dutifully sorting soda bottles, plastic bags and yogurt cups from the rest of the garbage. The more plastic you put in that blue bin, the more you’re keeping out of landfills and the oceans, right? Wrong. No matter how meticulous you […]

Neuronal recycling: This is how our brain allows us to read

Letters, syllables, words and sentences–spatially arranged sets of symbols that acquire meaning when we read them. But is there an area and cognitive mechanism in our brain that is specifically devoted to reading? Probably not; written language is too much of a recent invention for the brain to have developed structures specifically dedicated to it. […]

New solvent-based recycling process could cut down on millions of tons of plastic waste — ScienceDaily

Multilayer plastic materials are ubiquitous in food and medical supply packaging, particularly since layering polymers can give those films specific properties, like heat resistance or oxygen and moisture control. But despite their utility, those ever-present plastics are impossible to recycle using conventional methods. About 100 million tons of multilayer thermoplastics — each composed of as […]

New solvent-based recycling process could cut down on millions of tons of plastic waste

The solvent-targeted recovery and precipitation (STRAP) process recycles multilayered plastic waste into pure, reusable plastic materials, such as polyethylene (PE), ethylene vinyl alcohol (EVOH), or polyethylene teraphthalate (PET).

Closing the plastic loop with a one-pot recycling process

Image credit: Hans Braxmeier from Pixabay When we started using plastics about 70 years ago, not much thought — if any — was given to the implications of their lifespan and the fact that they can take centuries to decompose. Consequently, as plastics have diversified and become easier to manufacture, the planet is now straddling […]
