Over 150 known applications — from grain storage to silicone sealants, green concrete and beyond
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.
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).
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.
One of the most exciting and underappreciated industrial applications for diatomaceous earth. DE is used as a functional filler and rheology modifier in silicone adhesives, sealants, and putties — improving performance in ways that synthetic fillers cannot match, while offering a natural, non-toxic ingredient story.
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.
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.
Amorphous silica is used as an inert flow 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 a proven functional additive in paints, coatings, and plastics manufacturing — used as a matting agent, pigment extender, anti-blocking agent, and rheology modifier. Its porous structure scatters light to reduce gloss without affecting colour.
