We love a new
—particularly one that transforms would-be messy or bacteria-ridden household items into something sleeker, chicer, and cleaner.
Say hello to diatomaceous earth, a super absorbent substance crafted from an unexpected natural source.

What Is Diatomaceous Earth?

diatomaceous earth
Diatomaceous earth is a naturally-occurring material comprised of the
fossils of minuscule aquatic organisms
called diatoms. The resulting, silica-rich material can be used for pest control, pet care, and product innovation, all without much manmade interference.

Is Diatomaceous Earth Sustainable?

Yes, very.
Not only is diatomaceous earth regenerative, the eco material also serves as an atmospheric cleanser.
Living diatoms (a single-celled algae) have been found to remove carbon dioxide from the air, sinking it into the ocean and ultimately "capturing as much gas as nearly all of the trees," according to
Smithsonian Magazine

What Makes the Material Special?

Diatomaceous earth is natural, non-toxic, and, when processed, almost magical in its absorptive prowess. In fact, the material can hold nearly
150% of its own weight
in liquid.
