Diatomaceous Earth (DE)

Diatomaceous earth, also known as Diatomaceous silica (SiO₂*nH₂O), is the fossilized remains of tiny, aquatic organisms called diatoms that have accumulated, creating silica deposits. DE has high absorption, low bulk density, and high brightness. There are two primary types of diatomaceous earth deposits – saltwater and freshwater. Saltwater DE is commercially processed in the United States and primarily used as a filter aid. Freshwater DE is ideal for agricultural uses because it typically has a low crystalline silica content (amorphous), is highly absorptive, and is an ancient pest control agent. As awareness of and concern about chemical pesticides grow, diatomaceous earth has increased interest as a non-toxic and natural alternative. It is also seen as a natural anti-parasitic by farmers and ranchers.
Typical Applications

DE have been used in hundreds of industrial and agricultural applications. Current applications have DE being used as a filtration aid, mild abrasive in products including metal polishes and toothpaste, mechanical insecticide, absorbent for liquids, matting agent for coatings, reinforcing filler in plastics and rubber, anti-block in plastic films, porous support for chemical catalysts, cat litter, a stabilizing component of dynamite, a thermal insulator, and soil for potted plants and trees as in the art of bonsai.

Sustainable Qualities

Diatomaceous Earth is a naturally occurring, organic material mined from fossilized diatoms’ remains. This material is sustainable as it is a naturally occurring mineral that is biodegradable, non-toxic, and renewable. It is also highly effective as an absorbent, filtering agent, and abrasive material, making it ideal for a wide range of applications, such as water filtration, pet litter, insecticides, and polishing agents.
