Stone Dust

The most geographically common source of raw materials — readily available in almost every area where quarrying takes place.

Problem / Context

The stone crushing process generates large amounts of fine dust (crusher fines) with no clear market, often resulting in dust pollution and resource waste.

Because quarries are found everywhere, this is the most logistically accessible source of raw materials.

Market size

Market size

  • Hundreds of millions of tons of rock dust are generated globally every year.
  • Widespread distribution → reduces costs and risks in the raw material supply chain.
  • The demand for local building materials is always present.

Technical specifications

Technical specifications

  • Mineral composition depends on the type of bedrock (granite, basalt, limestone, etc.)
  • Fine, angular particles — improve product density and consistency.
  • Inert, stable, low in hazardous impurities.

ProtectGD solution

Stone dust acts as a fine aggregate and reactive filler in geopolymer formulations, helping to optimize structure and reduce material costs. Its widespread availability makes it an ideal raw material for scaling up decentralized production models in many locations.

BRING VALUE

Economy

Cheap raw materials, wide distribution → easy to replicate local-scale factories; low logistics costs.

Treating dust emissions at mines reduces air pollution and utilizes wasted resources.
