Inorganic Mineral Recycling

Many inorganic wastes closely mimic the naturally occurring raw materials used in cement manufacture e.g. foundry sands are chemically very similar to the sand that is used in cement manufacture. In these instances, the wastes can be sometimes sent directly to the kilns themselves. Wastes which tend to be silica, calcium, aluminum or iron rich tend to be the types of waste which fall into this category.

Potential ARMs must undergo rigorous testing designed to model their effect on cement clinker quality and environmental emissions before determining kiln usage rate and handling requirements.  Finally written approval must then be sought from the Environment Agency.

Tradebe manages over 110,000 tonnes of tonnes of waste to date for direct recovery which specifically include:

  • Seashells – in particular whole/crushed scallop and whelk shells
  • Alumino-silicate waste/grog – waste bricks crushed/whole from refractory manufacture
  • Iron oxide filter cakes – from Iron & Steel industry.
  • Spent mineral based catalysts – from Petroleum refining
  • Shot/forming fibre waste – from rock mineral wool insulation
  • Wood boiler ash
  • Air Pollution Control Residues/bottom ashes – from thermal processes.
  • Environmental control plant/water treatment solids – from water treatment/purification.
  • Foundry sands/sand castings – from foundries
  • Paper making sludge ashes – paper making industry.
