Is using grape-marc as fuel a risk?

Global greenhouse gas emissions need to be reduced. Implementing sustainable fuel sources in industry will help, but at what cost?

A Friday 13th risk assessment method was used to assess the inherent risk and economic impact of process failure. Historical data was collected from an Adelaide Brighton Cement Ltd. lime-kiln to produce input distributions used in the model. A thermal efficiency model of the process was produced, and a failure state defined.

Software was used to simulate the process and identify the probability of process failure. Substituting natural gas for grape-marc will have minimal impact on process failures while having an economic and environmental benefit. The uncontrolled variance in the natural gas flowrate has a much greater impact on the process than the proposed grape-marc substitution and could be investigated further.
