The Materials and Energy Potential Method for the quantitative distincion between Valorization and Elimination in the Cement Industry
report
This report proposes a quantitative method to distinguish between valorization and elimination of waste in a cement kiln. Examples are calculated to illustrate the consequences of the developed approach.
Valorization is defined as the processing of a waste in a cement kiln to substi-tute raw materials and/or fuels. In this case, the waste contributes, in a positive way, to the cement production process.
Waste combustion in a cement kiln without any substitution or process improvement and with the sole purpose of final waste processing is defined as elimination.
A review of proposed methods to define valorization shows that most approaches are based on the comparison of the waste with a fuel and that a clear appreciation of both the energy and the raw material value of a waste does not exist
