SUMMARY:Reduction of the carbon footprint:  low-carbon BF charge: Sintering substitution by cold process
DESCRIPTION:The paper presents a cold technology to produce a low-carbon BF feedstock which is used to supplement the sintering process of iron ore as it is currently known. The implementation of this production process of BF feedstock causes lower energy consumption compared to the high-temperature process of sintering. The result is quite a reduction of energy and significantly lower carbon footprint. 

A key factor in reducing the carbon footprint is the cold production process, as there are no direct CO2 emissions. In addition, the technology contributes to lower consumption of iron ore and coke and to efficient re-utilization of by-products from metallurgical processes like scale and fractions of dust and slag.

The BF burden produced by The EcolBriq® process shows mechanical product characteristics, very favorable mechanical and physical properties, such as: high strength 6-12 MP, which makes it easily ready as BF charge. An additional benefit of EcolBriq® is the possibility of year-round outdoor storage without changing the briquette properties. 

 A single production line with a capacity of 400KT / year can be utilized for a wide variety of materials with different structures, eg: powder, oxide, metal with sizes 0-200 mm. In contrast with sinter the briquette´s shape and size can be adjusted within a wide range to optimize the BF operation. This flexibility offers the possibility of creating an optimal low-carbon charge tailored to optimum blast furnace operation and quality of the hot metal. 

The presentation will show the advantages by two case studies, which quantify the results arising from:
i. Reduction of CO2 emissions for production of the EcolBriq®  feedstock compared to sinter
ii. Reducing the consumption of natural resources for EcolBriq®
iii. Dust reduction for EcolBriq® compared to sinter plant
iv. Maximizing the efficiency of the circular economy in BF operations
v. Reducing energy intensity
