(57) A method and system for predicting enrichment type in terms of volatile components in a cement plant resulting from a variation in the amount of volatile components circulating in a volatile component circuit of the facility following the addition of biomass or waste as fuel, comprising the steps of: obtaining the amount and composition of raw materials and fuels used; establishing a desired degree of thermal substitution; estimating a measure of the amount of volatile components present in raw materials and fuels; predicting a measure of the amount of volatile components in raw material and fuel upon adding biomass or waste; and generating a model relating the predicted amount of volatile components to the amount remaining; estimating the amount of sulphur oxide and chlorine in raw meal and relating it to the amount of volatile components remaining, obtaining an estimate of the risk of failure.
