The Low Carbon Clinker project aims to develop a low carbon clinker by changing its mineralogy and with an effective reduction of CO2 emissions, around 15% compared to the current ones. For this, it will be necessary to develop a new grate cooler with the modification of the current satellites of Secil Outão's Line 9.
This new technology will allow the co-processing of silicate materials which may be natural or from waste with latent hydraulicity, with potential for thermal activation. The improvement of the clinker cooling conditions, which will be carried out by thermal exchange with the material at room temperature, increases production without additional consumption of fuel or dedicated material.
With the production of this new low carbon clinker, a new range of cement types will be developed, with minimisation of negative impacts on product performance. The production of a new product range with a lower ecological footprint from the co-processing of clay materials or silico-aluminous waste meets the needs of a more circular economy.
