SUMMARY:Gaining value with ECOLBRIQ® - 2 possible applications of ECOLBRIQ®:  Reducing CO2 emissions and /or recycling of byproducts minimizing landfill
DESCRIPTION:Reducing CO2 Emissions:
Industrialization of the hydrogen reduction technology will take some years and further time will pass by until all blast furnaces worldwide will be substituted by hydrogen technology.  A bridging technology EcolBriq® offers tremendous value by reducing CO2 emissions on the regular BF production route partially substituting the iron ore sinter process. 

Recycling of by-products: 
Recapturing the valuable elements of by products and reducing landfill quantities is another EcolBriq® application creating a cost advantage.

The paper presents a cold technology to produce a low-carbon BF feedstock which can be used to supplement the sintering process of iron ore as it is currently known. The implementation of this production process of BF feedstock results in lower energy consumption compared to the high-temperature process of sintering. Thus, there is a significantly lower carbon footprint. 

In addition, the technology contributes to efficient re-utilization of by-products from metallurgical processes like scale and fractions of dust and slag. A single production line can be utilized for a wide variety of materials as feedstock with different structures, eg: from powder to lumps, minerals like oxide or metal ships with sizes 0-200 mm. 

The variety of advantages will be discussed:
i. Reduction of CO2 emissions for production of the EcolBriq® feedstock compared to sinter
ii. Dust reduction for EcolBriq® compared to sinter plant
iii. Maximizing the efficiency of the circular economy in BF operations
iv. Reducing energy intensity

Two case studies will show the results of briquetting two materials which cannot be recycled in sintering plant. First study is focused on briquetting of fine fraction of desulfurization slag and the second one will discuss recycling of oily scales.
