We develop sorting and recycling systems
for a circular economy.
Prevent release of highly climate‑damaging F‑gases from end‑of‑life insulation foams.
Enable circular material recovery
Support regulatory compliance for waste operators.
Ætheria is a climate-
tech company developing recycling technologies that mitigate ozone depletion and improve foam-waste logistics.
Our Mission is to:
A Hidden Threat
Ætheria addresses an overlooked climate threat: F-gases trapped in insulation foams
Insulation foam contains fluorinated gases, better known as ‘F-gases’.
These F-gases trap heat 6230 times more effectively than CO2. Making it one of the most worrisome greenhouse gases of all time.
On top of that, these F-gases are notorious ozone-depleting gases. Increasing the hole in the ozone layer drastically.
