SeaChange uses plasma arc technology to save the oceans from plastic waste

via Inhabitat.com

SeaChange will outfit its ships with something called the Plasma Enhanced Melter (PEM). The PEM uses plasma arc technology to zap plastic and other trash before it enters the ocean. Plastic is shredded before it enters the Plasma Arc Zone.

Instead of leaving harmful residues like conventional waste treatment methods, plasma arc technology uses high temperature and high electrical energy to heat waste, mostly by radiation. Organic material can be burned down into a combustible gas called syngas, which can be used as clean fuel for SeaChange’s ships. Inorganic components wind up as glassy slag. This reusable black glass is said to be nontoxic and safe for marine life.

A floating device created to clean up plastic from the ocean is finally doing its job, organizers say

via (CNN) A huge trash-collecting system designed to clean up plastic floating in the Pacific Ocean is finally picking up plastic, its inventor announced Wednesday.The Netherlands-based nonprofit the Ocean Cleanup says its latest prototype was able to capture and hold debris ranging in size from huge, abandoned fishing gear, known as “ghost nets,” to tiny microplastics as small as 1 millimeter.
