Optimising AF co-processing

The co-processing of alternative fuels comes with a range of technical challenges such as the variability of fuel properties, control of system stability and the impact on clinker quality. An integrated technological framework has been developed to overcome these barriers and case studies have shown that thermal substitution rates of over 60 per cent can be achieved, resulting in significant reductions of CO2 emissions while maintaining stable clinker quality.
