Co Processable Waste


Holcim Group's vast international experience in this field, built over more than 30 years of uninterrupted commitment to environment care, ascertains that the following types of waste can be co-processed (pre-treated, if necessary, and co-incinerated) as alternative fuels (this list is not exhaustive though):

  • used oils (motor, transmission, industrial oils), including oil filters
  • sludge, acid and neutral tars, used earthy filters, wax waste resulted especially from oil and oil by-product processing etc
  • rubber (including whole/shredded tires)
  • wood (including wood treated with wood preservatives or painted wood)
  • paper (including printed paper), cellulose waste resulting from paper production or recycling
  • plastic masses (including used packagings)
  • tars from the steel industry (coke ovens)
  • waste resulted from water treatment (sludge)
  • organic components from the pharmaceutical industry and the chemical industry
  • organic components from the dyes, solvents and lacquers industry.

As for material recovery, the following types of waste can be co-processed in cement plants as alternative raw materials:

  • blast furnace slag, fly ash from coal-fired power plants, pyrite ash,
  • phospho gypsum and rhea gypsum (a residue resulted from the neutralization of sulphurous gas from thermo power plants)
  • silica wastes, used sands,
  • clay residual materials, especially from the metallurgical, steel, mining, energy and chemical industries.
