Title:

Building Products from Kota Stone Waste

Value Proposition:

The amount of wastes generated during cutting, querying, sawing and polishing processes from flaggy limestone industries easily reaches up to 10-12 MT per year. Flaggy limestone slurry consist of 85% water and 15% flaggy limestone powder. Thus, total solid waste generation easily reaches about 4.5-5 MT annually i.e. approx. 75-80% of total mined out reserves. It contains around 38% lime, 15-18% silica, 3-4% alumina and around 1-2% iron as FeO and Fe2O3. Thus, looking to such huge quantity of wastes as minerals or resources, there is a tremendous scope and need for recycling and using such stone wastes to develop sustainable building materials.

Summary Application:
  • Floor tiles- Light traffic loads & heavy traffic conditions
  • Paver blocks- Non traffic to Heavy traffic conditions
  • CFC blocks- Infill material & brick replacement
Advantages:
  • Employment generation through setting up of industry
  • Minimization in environmental pollution
  • Saving of natural resources through waste utilization
Commercialization Status: Already Commercialised
