Over 150 known applications — from grain storage to green concrete and beyond
Diatomaceous earth has been used by civilisations for thousands of years. Modern science continues to discover new applications for this fossil mineral's unique physical and chemical properties.
Applied at 1–2 kg per tonne of grain, DE creates a mechanical barrier against weevils, beetles, and moths — no chemical residues, no withholding period. Also used as a soil amendment improving water retention, cation exchange capacity, and silica availability for plant uptake.
Research shows 15% replacement of Portland cement with DE increases compressive strength by 53% while improving porosity and water permeability (ANOVA analysis, p<0.05). Portland cement alone pumps roughly 6 billion tonnes of CO₂ annually — DE is part of the solution.
DE works mechanically — absorbing the protective waxy coating of insect exoskeletons, causing dehydration. No chemical resistance can develop. No withholding period. Particularly effective for red mite, litter beetle, and fly larvae control.
Chemically inert, high-absorbency, non-reactive with most industrial substances. Non-crystalline profile provides safer workplace exposure documentation compared to calcined alternatives. Australian-sourced — supports local supply chain claims.
Amorphous silica enhances the absorption and bioavailability of other nutrients and herbs through multiple mechanisms — gut wall integrity (orthosilicic acid), physical carrier matrix (494.4 m²/kg surface area), prebiotic effect, and detoxification of gut interference.
Superior natural absorbency outperforms clay-based litter volume for volume. Natural odour control through moisture absorption. Non-crystalline and non-toxic — safe for household and pet environments. Biodegradable and naturally sourced.
Researchers at the University of California, Riverside have been exploring DE as a source of silica for EV battery anodes. Silicon is known to significantly improve battery energy efficiency — and DE provides a natural, abundant, low-cost silicon source with unique porous structure.
DE filters particles as fine as 1–3 microns — far finer than sand filters (20–40 microns). Used in swimming pools, water treatment, beverages, and food processing. Note: pool/filter grade DE is calcined and NOT BSiO₂ product — our grades are for the food and industrial anti-caking market.
DE is found in thousands of personal care products globally — its mild abrasive, absorbent, and light-diffusing properties make it valuable in cosmetic formulations. Used in skin care, toothpaste, and makeup.
Amorphous silica is used as an inert anti-caking agent and moisture absorber in ANFO (ammonium nitrate fuel oil) explosive formulations. Australia uses more commercial explosives than almost any other country — the mining sector represents a significant volume opportunity.
DE is registered as a natural insecticide in many countries. It works by mechanical dehydration — no chemical toxicity — meaning insects cannot develop resistance. Safe for beneficial insects when applied correctly (avoid flowers and pollinator areas).
