Engineering the Recovery of Our Atmosphere.
We recover, recycle, and destroy climate-damaging F-gases trapped in end-of-life insulation foams.
A Hidden Threat
Insulation foams contain fluorinated gases (F-gases) with a global warming potential up to 6,230x that of CO2. These same gases erode the ozone layer, contributing to more than 60,000 skin-cancer deaths every year.

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.
