Exergoeconomic methods provide an effective approach for identifying,   evaluating and reducing thermodynamic inefficiencies and costs in an energy   system. The aim of this paper is to show the potential for cost reduction on   the demand side, using the exergoeconomic method in the example of real   processes for coffee roasting. More than 6.5•109 kg of coffee beans is   roasted worldwide annually, mostly in batch roasters. Near the end of the   roast, roasting coffee emits volatile organic compounds, carbon monoxide and   other pollutants, which in many industrialized countries have to be oxidized   in afterburners. Afterburners release exhaust gases with a temperature of   250-450°C, depending on the roasting process and the method of exhaust gas   cleaning. The aim of this paper is to use exergy analysis and exergoeconomic   performance evaluation to determine the energy use for coffee roasting and   the afterburning process, and evaluate the way to utilize waste heat and   reduce costs in the factory. For roasters with the capacity of up to 4 tons   of green coffee beans per hour, the potential of heat recovery is 1.1 MW and   the possibility to save money is around 60,000 € per year. This case study is   similar to many others worldwide, and the results of this analysis could lead   to more general conclusions
