A study conducted by the Netherlands Organization for applied Science Research (TNO) compared the environmental impacts of using waste as an alternative fuel andraw materialin the cement industry, andburning wasteinhazardous waste incineratorswhilerecovering electricityand steam.

Steel slagis awaste material producedduring the process ofsteelmaking. For many years, a large amount ofsteel slagwas deposited inslag storing yards, occupied farmland, silted rivers and polluted the environment. Manysteel plantsin the world have already taken upinnovative waste recycling technologies...

The output of waste materials suitable as cement replacement (slags, fly ashes, silica fumes, rice husk ash, etc.) is more than double that of cement production. These waste materials can partly be used, or processed, to produce materials suitable as aggregates or fillers in concrete.

Thecement industrycan turn thewasteproblem into a value-creating opportunity by using thewasteto substitute fossil fuels and naturalraw materials: the co-processing. Co-processing is the use ofwaste materialasraw materialsor as a source of energy, or both, to replace natural mineral resources and fossil fuels such as coal, petroleum ...

Alternative Raw Materials for CementSteel manufacturing by-products such as Electric Arc Furnaceslag, Ladle Furnaceslagand mill scale are valuable secondaryraw materialsfor thecement industry. Under the Circular Economy context, industrialwasteand byproducts should be first considered as secondaryraw materialsoralternativefuels for ...

The mainraw materialused incement productionhas traditionally been limestone. Limestone is abundantly available, but over 60% of theindustry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.

Brazil: Votorantim Cimentos said that the proportion ofalternative raw materialsused in Braziliancementis one of the best in the world, according to data from the Brazilian constructionindustryassociation SNIC. In 2013, 91% of all thecementcommercialised in Brazil had some additive in addition to the clinker derived from limestone used incement production.

Abstract. Thecement industryhas for some time been seekingalternative raw materialfor the Portlandcementclinkerproduction. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicateraw materialfor theproductionof Portlandcement…

One way for Lafarge to emit less carbon dioxide (CO2) is to usealternative raw materialsto replace limestone in the manufacture ofcement. Derived from natural or industrial sources, suchalternativeshave the same properties as clinker, the main ingredient in conventionalcement.

Clearly, the Indiancement industry’s demand profile offers an opportunity to be a mega participant inwastemanagement. Withproductionat 298 mtpa in 2017-18 and expectations of over 550-600 mtpa by 2025, the demand profile ofraw materialsis equally large. To meet numbers like that, theindustrywould require over 51 million tonnes of ...

Waste slag as alternative raw materialin the ... - ALF-CEMIND.Waste slag as alternative raw material in the cement production. Ferrousslagis produced by adding slagging agents such as limestone or dolomite and/or fluxingmaterialsto blast furnaces and steel furnaces to strip the impurities from iron ore, steel scrap, and other iron or steel input feeds.
