Halting new marine plastic inputs by 2050 is the core objective of the Osaka Blue Ocean Vision, which was shared and endorsed alongside the G20 Implementation Framework for Actions on Marine Plastic Litter. However, stopping new plastic inputs will not remove existing marine debris, which can gradually fragment into microplastics that are difficult and costly to remove. Source reduction must therefore be accompanied by cleanup of legacy plastic debris.

A new process turns plastic waste into gasoline and diesel fuel

Scientists at Oak Ridge National Laboratory have developed a surprisingly simple way to turn polyethylene, the common plastic used in shopping bags and cutting boards, into gasoline and diesel-like fuels. The process uses inexpensive aluminum-based molten salts to break long plas

Laser temporarily reprograms ultrathin optical device without electrodes

A tiny device that can be reprogrammed using a laser could lead to adaptable devices for computing, imaging and telecommunications. Most devices are built to perform a particular job. If you want them to do something different, you generally need to replace a component, rewire th
