These are simulated educational cases built around the decisions cement plants actually have to defend: process performance first, investment value second.
A low fuel price, a high exhaust temperature or a larger fan can look like a clear opportunity. The useful question is what happens after moisture, ash, capacity, pressure loss, maintenance and lost production are counted.
Decision cases about RDF/SRF, moisture, NCV, ash, chlorine, kiln capacity and fuel economics.
The supplier price per tonne is lower than the current fuel cost. The contract appears profitable until the plant checks moisture, NCV, ash, chlorine and the extra fuel mass required.
Your decision: Should the contract be approved from price per tonne alone?

Decision cases about recoverable heat, system limits, electricity generation and project return.
A preliminary WHR proposal uses one high exhaust-temperature reading and promises a short payback. The plant has seasonal production changes and frequent kiln stops.
Your decision: What must be checked before approving the CAPEX?
