Chemical recycling makes useful product from waste bioplastic

Chemical process can be used to break down real consumer plastics and produce green solvent

25-May-2020

A faster, more efficient way of recycling plant-based "bioplastics" has been developed by a team of scientists at the Universities of Birmingham and Bath. The team has shown how their chemical recycling method not only speeds up the process, it can also be converted into a new product - a ...

A peachy defense system for seeds

24-May-2016

Don't eat the core, it's poisonous: it's something parents often say to their children before they eat their first peach. Peach pits, which are hidden inside the nut-like husk, do in fact contain amygdalin, a substance which can degrade into hydrogen cyanide in the stomach. But peaches, apricots ...
